Guest guest Posted May 14, 2010 Report Share Posted May 14, 2010 could virgin coconut oil (MCTs) of course with vitamin B6, zinc, also have omega 3 (fish oil, salmon, flax) be a great help to feed the brains of the children? from Kathy's information w/ more from willis go to <http://livinlavidalowcarb.com/blog/?p=4181> http://livinlavidalowcarb.com/blog/?p=4181 to read about it to listen to this: http://www.thelivinlowcarbshow.com/shownotes/wp-content/uploads/llvlc240-dr- mary-newport.mp3 and turn up your computer speakers to listen. after listening, I believe the cinnamon capsules would also be beneficial. decreased glucose uptake? if you get cold sores, you should take coconut oil go to You must supplement vitamin B6, zinc, also have omega 3 (fish oil, salmon, flax) go to <http://coconutketones.com/> http://coconutketones.com/ for more information excerpt: In Episode <http://www.thelivinlowcarbshow.com/dr-mary-newport-coconut-oil-alzheimers-c ure-episode-240/> 240 of “The Livin’ La Vida Low-Carb Show with Jimmy ,” we are privileged to hear from Dr. Newport <http://www.coconutketones.com/biography.html> who I first found out about after reading this <http://tampabay.com/news/aging/article879333.ece#comments> St. sburg Times story about how feeding her husband coconut oil greatly IMPROVED his Alzheimer’s. It was such an extraordinary story that I just HAD to book her for an interview to tell this remarkable story to my listeners. She correctly identifies the glucose connection to Alzheimer’s disease which is now becoming well-known as Type 3 diabetes <http://livinlavidalowcarb.com/blog/?p=3495> , how ketone bodies are the preferred fuel for brain function, and why medium chain triglycerides (MTCs) found in coconut oil are a miracle for her husband’s condition. This is one of the most stunning personal testimonies of how a high-fat, low-carb ketogenic diet can dramatically improve health. You can’t help but be a believer after listening to Dr. Newport gush about her husband Steve is overcoming his tremors, regain cognitive function, and DEFEATING his Alzheimer’s. Note: You must supplement vitamin B6(p5p), zinc, and magnesium when using coconut oil. i get mine at iherb.com Scroll down for more detailed information. There are lots of ways to get coconut oil into the diet: stir coconut oil in some tea; make macaroons; replace some of the butter in baking with coconut oil; and use it in cooking/sautéing. 's oil blend (see below) is a good way to incorporate coconut oil in cooking and salad dressings. More detailed information from forum below. What are MCT's? Dear Doug: This is an abbreviation for Medium Chain Triglycerides. This fatty acid isn't digested in the manner of other fats, but is converted to ketones which the brain can use as fuel. The recommended amounts of coconut oil is one tablespoon to three tablespoons a day, depending upon the degree of insulin resistance. It is said that diabetics, whose bodies are already converting other fats to ketones may need to be cautious. There are ketone strips to keep track. MCT oil may cause diarrhea when it is consumed in large amounts (small amounts throughout the day promote greater tolerance). To utilize these MCT oils requires coenzyme B6 (Pyridoxal 5' Phosphate, often referred to as P5P), and magnesium. Some might have essential fatty-acid deficit symptoms, but the problem could really be a lack of vitamin B6 and magnesium. You must supplement vitamin B6, zinc, and magnesium, especially when using coconut oil. Remember, that a zinc deficiency adversely influences coconut oils tending to a fatty liver. P5P is apt to be more effective because a large majority of " healthy " people do not convert the regular vitamin B6 to its metabolite form. One study showed 19% were deficient in one or more B-vitamins, but 62% were deficient in the necessary metabolites. Zinc deficiency can also look like a fatty acid deficiency, and children with milk intolerance have been shown to be deficient in EFAs. MCTs can improve liver function and fat absorption. Unlike other fats and oils, they are not transported through the lymphatic system during digestion, but go directly to the liver where they are burned to provide energy. Burned like carbohydrates, MCTs are a good source of energy for athletes. They have been shown to lower cholesterol levels and help people with irritable bowel problems MCTs Promote Weight Loss Several studies have shown that medium chain triglycerides (MCTs) promote weight loss. One study showed that rats fed long chain fatty acids (LCTs) stored body fat, while rats fed MCTs reduced body fat and improved insulin sensitivity and glucose tolerance...(See June, 2003, Obesity Research) In March of 2003, this same journal published findings that Medium-chain triglycerides increase energy expenditure and decrease adiposity in overweight men. The study was conducted with twenty-four healthy, overweight men with body mass indexes between 25 and 31 kg/m. They consumed diets rich in MCT or LCT for 28 days, each in a crossover randomized controlled trial. Those consuming MCTs lost more weight and had more energy than those consuming LCTs (in this case olive oil). An earlier study in 2002, The Journal of Nutrition came to the same conclusion. They reported that MCTs are more readily oxidized in the liver than LCTs, which leads to more energy and less weight gain. The study concluded that MCTs increase energy expenditure, may result in faster satiety, and facilitate weight control when included in the diet as a replacement for fats containing LCTs. Scores of people have discovered the benefits of MCTs firsthand. Sharon writes the following to the coconut discussion group: I have had the same problem with sluggish metabolism and weight gain since having children. Even a no-calorie diet (fast) for 5 days did not work. As soon as I started taking Virgin Coconut Oil the fat began to melt and I have lost 20 pounds. Over the same period of time, my 13- year- old daughter who was very chubby and very worried about it, but could not bring up the self-control to renounce some of her favorite fatty foods, lost about 10 pounds. She now has the perfect figure, to her great joy! Pants she was bulging out of a year ago hang loose on her! To obtain MCTs cook with a quality coconut oil and use if for salad dressing. Mix it in a smoothie. Start with a very small amount. I append a paper that elaborates on the subject. Warmly, Willis Hello List mates: Some have recently asked about MCT oils. Here are the answers.

Uses of MCT Oils By Darnley, RD ---------------------------------------------------------- Dietary fat and the fat stored on our body as adipose tissue are in the form of triglycerides, which contain long-chain fatty acids (14 carbons or more) [1]. The most prevalent fatty acids found in food are oleic (C18:1), palmitic (C16:0), stearic (C18:0), and linoleic (C18:2). Due to molecular distillation in the early 1960's, it became possible to prepare a mixture of triglycerides that contain only medium-chain fatty acids (MCFA; 6-12 carbons). MCFA's are naturally found in coconut oil, palm kernel oil, and milk. Medium-chain triglyceride (MCT) oil is comprised of primarily caprylic (C8:0) and capric (C10:0) acids with a very small percentage of caproic (C6:0) and lauric (C12:0) acids, which are esterified to a glycerol backbone. MCT oil is a light yellow, translucent, odorless liquid at room temperature (MCT's are also available in powder form). Although completely saturated, it is not atherogenic [2] or solid in consistency like other saturated fats, due to the shorter chain lengths of the fatty acids within the oil. The energy value of MCT oil is approximately 7-9 Calories per gram, and this fat is metabolized differently than long-chain triglycerides (LCT). Complete hydrolysis to MCFA's and small amounts of monoglycerides occurs in the stomach with very little secretion of pancreatic lipase or bile acids. After MCFA's are absorbed into the intestinal mucosal cells, they are not resynthesized into triglycerides and incorporated into chylomicrons as are long-chain fatty acids. MCFA's bypass the lymphatic system and are carried by the portal vein directly to the liver, where they are metabolized to produce carbon dioxide, ketones, and acetate. Therapeutic uses Due to the unique properties of MCT's, they are used as a fat source in many disease states. MCT oil can be used to add calories to a formula or diet in the case of malabsorption syndromes. Due to a more rapid digestion and absorption, MCT's increase the osmolality of formulas. Since it requires lower concentrations of bile or pancreatic lipase for digestion and absorption, patients with bile acid and pancreatic lipase deficiencies benefit from adding this fat source to the diet. MCT's comprise the lipid component in many infant formulas because infants rely on lingual lipase for lipid digestion when pancreatic function is not fully developed. MCT's are contraindicated for people with diabetes, due to the risk of hyperketonemia. MCT's are also generally not recommended for people who have compromised hepatic function because a diseased liver does not have the ability to clear the increased levels of MCFA's. Essential fatty acids and fat-soluble vitamins must be added to MCT oil if it is a significant source of fat in the diet. MCT oil is also unpalatable for some people and may cause diarrhea when it is consumed in large amounts (for people who experience GI distress, small amounts throughout the day promote greater tolerance). The high cost of MCT oil is another limitation to its use in the diet. These factors should be addressed by the dietitian or physician after it is determined whether a client or patient can benefit from MCT oil. Using coconut oil is more economical. Alternative uses Besides being used to alleviate the effects of malabsorption syndromes, MCT's have some nontraditional applications. The ketogenic diet has been effective in treating chronic seizures. MCT's are used to induce ketosis in these patients. When MCT's are substituted for long-chain triglycerides in the diet, animals gain less weight, store less adipose, and experience an increase in metabolic rate [3, 4, 5]. MCT-fed mice also have been shown to possess increased endurance over that of LCT-fed mice [6]. It is probably these factors that have brought MCT oil into the market of ergogenic aids and dietary supplements. Due to the caloric value of MCT oil, it can be effective in adding energy to the diet. There is far less research conducted in human subjects, and the results from animal studies do not necessarily apply to humans. The amount of this fat that is consumed by animals to create a performance effect is far more than the average human consumption of fat. Nevertheless, it could be beneficial to substitute MCT oil for other oils that contain long-chain fatty acids, since scientific evidence indicates that MCT's may be less easily stored as adipose. Recipes using MCT oil have been published [7], and MCT oil can be substituted in place of most cooking oils. _____ From: Williss [mailto:Williss ] Sent: Thursday, May 13, 2010 7:35 AM Williss Subject: more on virgin coconut oil and alzherimers A <Williss;_ylc=X3oDMTJjYzY0cm84BF9TAzk3MzU5NzE1 BGdycElkAzM0Njg5NwRncnBzcElkAzE3MDUxMjYxNzEEc2VjA2hkcgRzbGsDaHBoBHN0aW1lAzEy NzM3NTA0ODQ-> place to exchange ideas and experiences and find help for Autistic and ADHD Kids, unrestricted by stringent *moni Messages In This Digest (2 Messages) 1.

Do we not owe it to ourselves and to our family to care for ourself FIRST? What does the Stewardess say on preparation for takeoff? " Mother's, put the oxygen mask on yourself first, then put one on your children " . This makes sense. Who will put the mask on the children if you pass out? Please, consider your worth and the need to care for yourself first. You said there were supplements he could take in the place of the Risperdal. Can they be taken in addition to the Risperdal and used as an adjunct to keep him from needing a larger dose? Yes, to all those questions. I would never suggest your stopping Risperdal without the help of your doctor in reducing dosage as you wean off. To quit these type drugs cold turkey can be disastrous. These are some of the side effects of continued usage. I realize you are taking half milligram, whereas the normal dose is up to 6 mg, nevertheless, I know one adult who, on the low dose, had to change drugs because of elevated liver enzymes. >>>Risperdal has been linked to diabetes and, more specifically, Type 2 diabetes. Other serious side effects include Neuroleptic Malignant Syndrome (NMS), a potentially fatal syndrome involving muscle rigidity, liver damage, and irregular blood pressure and pulse.[vii] >>> >>>risperidone is often used; however, a major study followed children for only 8 wk; some patients develop tardive dyskinesia after several months. >>> Risperidone is usually thought to antagonize the overactive serotonin and dopamine receptors, but it also affects norepinephrine: >>>risperidone (0.5 mg/kg), the 5-HT (serotonin) syndrome was completely inhibited, and the Noradrenaline (NA) level increased to 6.5 times the pre-administration level. >>> Dopamine antagonists, such as Risperdal, can be very effective in controlling Exposure anxiety, panic attacks, and OCD. Dopamine increases proportionately to the amount of stress. The higher the adrenaline level, the greater the increase in dopamine. Serotonin also increases. Dopamine and serotonin decrease during partial, toxic withdrawal states. But as long as caffeine remains in the toxic body, neurotransmitters never adjust to the victim's natural state. >>> In addition to caffeine and stress induced adrenaline raising dopamine levels, mercury is a known inducer of excess dopamine levels. >>>Citation: Faro LR, do Nascimento JL, Alfonso M, et al. Protection of methylmercury effects on the in vivo dopamine release by NMDA receptor antagonists and nitric oxide synthase inhibitors. Neuropharmacology. 2002 Sep42(5)612-8. PMID:11985818. Abstract: The possible protective effects of NMDA receptor antagonists dizocilpine (MK-801) and D(-)-2-amino-5-phosphonopentanoic acid (AP5), and nitric oxide synthase (NOS) inhibitors L-nitro-arginine methyl ester (L-NAME) and 7-nitro-indazol (7-NI) on the methylmercury (MeHg)-induced dopamine (DA) release from rat striatum were investigated using in vivo microdialysis. Intrastriatal infusion of 400 microM or 4 mM MeHg increased the extracellular DA levels to 1941+/-199 and 7971+/-534% with respect to basal levels. Infusion of 400 microM or 4 mM MeHg in 400 microM MK-801 pretreated animals, increased striatal DA levels to 677+/-126 and 2926+/-254%, with respect to basal levels, these increases being 65 and 63% smaller than those induced by MeHg in non-pretreated animals. Infusion of 400 microM or 4 mM MeHg in 400 microM AP5 pretreated animals, increased striatal DA levels to 950+/-234 and 2251+/-254% with respect to basal levels, these increases being 51 and 72% smaller than those induced by MeHg in non-pretreated animals. Infusion of 400 microM MeHg in 100 microM L-NAME or 7-NI pretreated animals, increased the extracellular DA levels to 1159+/-90 and 981+/-292%, with respect to basal levels, these increases being 40 and 50% smaller than those induced by MeHg in non-pretreated animals. In summary, MeHg acts, at least in part, through an overstimulation of NMDA receptors with possible NO production to induce DA release, and administration of NMDA receptor antagonists and NOS inhibitors protects against MeHg-induced DA release from rat striatum. >>> <<<Elevated dopamine levels are closely linked to schizophrenia. Excess dopamine may cause sleep disorders and Insomnia. >>> >>>dopamine(DA). Low levels of dopamine are vasodilatory (can be blocked by nimodipine and hydergine). High doses are vasoconstrictive. <<< >>>One therapeutic approach in the treatment of patients with infantile autism involves the use of dopamine antagonists. The dopaminergic system of the brain affects motor behaviors. Its abnormalities involve excess motor activity and stereotypes similar to those observed in autistic patients. Intellectually subnormal autistic children, particularly those with severe hyperactivity and stereotypes, were found to have excess dopaminergic activity as measured by high levels of homovanillic acid in the CSF (Cohen, et al) Note: Low dose Risperdal™ (0.5 mg) has freed one adult from OCD, Exposure Anxiety, and panic attacks apparently through its effect in reducing dopamine activity. Why not build acetylcholine by supplementing lecithin, or choline, or CDP Choline, or N-acetylcholine, or perhaps better, DMAE? Omega-3 fatty acids of cod-liver oil are more effective than drugs used for schizophrenia according to studies done at Harvard medical School. See " Mastering Autism " , Section " Managing Fatty acids " for the correct way to introduce fatty acids. >>>The N-Methyl d Aspartate receptor (NMDA is activated mainly to amplify the effect of glutamate during periods of especially intense excitation. Since the blockade of NMDA receptors in the cerebral cortex enhances the release of dopamine from lower brain regions, reduced glutamate transmission could be the ultimate cause of excessive dopamine activity in the brains of schizophrenic patients. High levels of another NMDA receptor blocking agent, kynurenic acid, are found in the spinal fluid of patients with AIDS dementia and in many autistic children. The amino acid glycine and (at much lower doses) its chemical relative, the antitubercular drug D-cycloserine, indirectly activate NMDA receptors and may reduce apathy, withdrawal, and cognitive impairment in schizophrenic patients. >>> The natural NMDA receptor blocking agent (calcium channel blocker) is magnesium, manganese, and zinc. We normally need a blocker not an activator. The schizophrenic and those with a dopamine overload need an NMDA activator. >>>Excess dopamine is typically caused by a vitamin B6, zinc, and/or acetylcholine deficiency, or a Clostridia overgrowth (produces dopamine). Cadmium toxicity suppresses norepinephrine, serotonin, and acetylcholine, but not dopamine. Removal of heavy metals allows restoration of near-normal levels of acetylcholine. High estrogen levels from soy foods and from flax-oil tend to cause increased absorption of copper and cadmium. Cadmium affects verbal ability more and lead affects performance measures more. The high estrogen and/or excess dopamine can create anxiety in the child. When anxious and fearful, the sympathetic nervous system kicks in and or having been made predominant, anxiety is the result. It's sort of a Chicken or egg question. The Sympathetic Nervous System is balanced by the Parasympathetic Nervous System. The overactive Sympathetic is suppressed by magnesium and the diminished Parasympathetic function is stimulated by potassium. Here we see a need for magnesium and potassium supplementation to restore a balance. Magnesium deficiency keeps potassium from being replenished in the cell. Cigarette smoke (including secondhand smoke) reduces MOA (, an enzyme needed to break down dopamine and other chemicals, compromising the body's ability to detoxify itself of many harmful substances. Smoking (and eating white flour) builds cadmium toxicity and also depletes the amino acid cysteine needed to make metallothionein, sulfates, and glutathione necessary to detoxify the body of heavy metals, phenols, amines, and other poisons. The result may be an out-of-control, panic-stricken child suffering Environmental Anxiety. This behavior is often dramatically controlled by ¼ to ½ mg Risperdal™. It's better to correct the above problems and to build acetylcholine, though the latter may be difficult in view of cadmium suppressing the needed enzyme. Magnesium, calcium, selenium, zinc, melatonin, and metallothionein protect the cells against cadmium and mercury, and germanium protects the liver against damage from cadmium. Heavy metals can be chelated by oral supplements of Ambrotose AO™, IP-6 (phytic acid), zinc, manganese, selenium, N-acetylcysteine (NAC), serine, melatonin, Cilantro, transdermal or oral glutathione, and vitamins B6, C, and E. The initial treatment must be gradual to avoid a sudden dumping of metal toxins from tissues, which could cause kidney damage and a worsening of symptoms. Choline (Lecithin) is antidopaminergic, as is anything that will build acetylcholine. See " Mastering Autism " for several ways to build acetylcholine. Supplementing DMAE (crosses the BBB and supplies choline) will work well for the overmethylated person. >>> I have mentioned building Acetylcholine several times. That seems the logical and effective way to balance excess dopamine, which is often an imbalanced ratio with acetylcholine, but this won't work for the undermethylated (55%) of Autistic children. See Dr. Walsh's explanation below. See " Mastering Autism " for details of undermethylation. What would Gaba do, if I tried it along with the Risperdal? It is logical that the lower dose he can take the better off he will be. Yesterday was his 3 day on the .5mg. He had 1 episode; milder than the others. The day before he had none. The doctor said to increase on day 5 to 1 mg. if he showed no side effects and his behaviors were not under control. I would certainly ask the doctor about the use of low dose GABA. Should you decide to use it, start at a low amount and increase as you observe his response. Too much will make him lethargic. I have wondered for a while if some of the issue is the MSG in the KFC strips. He has been eating them daily since he was 9 and seems to crave them. He increased from 3 to 6 about a month before these behaviors got really out of control. Is that a possibility? This is typical allergic response. When this occurs, there is only one solution: Tough Love! You have to remove all KFC foods. Frequently the addiction is to their French Fries. No, he won't starve. After a couple of days for the allergens to clear, he will begin eating a more normal diet. He was also taking Bentyl and Allegra. The interaction of these two is possible. They are listed on the handout as likely to interact. The pharmacist said that possible side effects from Bentyl was psychosis and Allegra, panic attacks. Isn't that just Lovely? When we stopped the medication the episodes did not go away, however. Also, he has antibodies to gluten. Could the little bit of gluten in the breading for the strips and a hotdog bun send him over the edge like this? If he doesn't eat the 2nd 3 strips, he eats a hotdog with ketchup in the evening. The time of day these start is about 4-5 hours after he has eaten his lunch(3 Crispy Strips & mashed potatoes and gravy-also full of msg.) Problem is he refused to eat anything else. That is only a problem for a tenderhearted Mother! He must be denied all these foods until he is free from the allergens and ready to eat normally. T his diet will not long sustain health or normal function. The hotdogs are loaded with phosphates which bind calcium and magnesium. Ketchup is loaded with sugar and salicylates. the chicken strips are loaded with MSG, as you said, and with oxidized fats, probably hydrogenated soy oil. The bread and breading is loaded with gluten. When one is gluten sensitive, it only takes the use of a utensil used with gluten in preparing non gluten meal to cause a reaction. Remember how the Jews use a new plate for certain things to avoid cross contamination? Yes, those exposures to gluten are deadly to those sensitive. Thanks again. Drissia I append a discussion of controlling dopamine. Summarized these are points of interest: The following things enhance dopamine levels: 1. Stress, and these kids are stressed to the breaking. High adrenaline levels promote high dopamine levels that, among other things, is vasoconstrictive. 2. Mercury and cadmium toxicity, and probably other metals. Cadmium suppresses norepinephrine and serotonin, but not dopamine. Soy and flax oils and bleached flours increase cadmium and lower acetylcholine, leading to anxieties and stereotypes of Autism. Magnesium, calcium, selenium, zinc, melatonin, and metallothionein protect the cells against cadmium and mercury, and germanium protects the liver against damage from cadmium. Heavy metals can be chelated by oral supplements of Ambrotose AO™, IP-6 (phytic acid), zinc, manganese, selenium, N-acetylcysteine (NAC), serine, melatonin, Cilantro, transdermal or oral glutathione, and vitamins B6, C, and E. The initial treatment must be gradual to avoid a sudden dumping of metal toxins from tissues, which could cause kidney damage and a worsening of symptoms. 3. Caffeine and nicotine. Avoid all exposure to second-hand smoke. Cigarette smoke prevents the breakdown of dopamine. 4. Blocking of the NMDA receptors reducing glutamate transmission. The NMDA receptors can affect different persons differently. Typically, activating of the NMDA activates a signal for a body function. Repeatedly signaling for that activity can cause overactivity (excitotoxity), hyperactivity, and even neuronal death. If overactivity is evident, then blocking needs to be promoted. If underactivity is evident, then activation is desired. These snips present the dilemma of determining what is needed. >>> N-Methyl d Aspartate receptor (NMDA is activated mainly to amplify the effect of glutamate during periods of especially intense excitation. Since the blockade of NMDA receptors in the cerebral cortex enhances the release of dopamine from lower brain regions, reduced glutamate transmission could be the ultimate cause of excessive dopamine activity in the brains of schizophrenic patients. High levels of another NMDA receptor blocking agent, kynurenic acid, are found in the spinal fluid of patients with AIDS dementia and in many autistic children. The amino acid glycine and (at much lower doses) its chemical relative, the antitubercular drug D-cycloserine, indirectly activate NMDA receptors and may reduce apathy, withdrawal, and cognitive impairment in schizophrenic patients. >>> The natural NMDA receptor blocking agent (calcium channel blocker) is magnesium, manganese, and zinc. We normally need a blocker not an activator. The schizophrenic/autistic who is apathetic apparently need glycine as an activator. <<< 5. A deficiency of vitamin B6, zinc, and/or acetylcholine. Yet building acetylcholine may be contraindicated. DMAE is the best way to supply choline and build acetylcholine, but that is very damaging to anyone who is undermethylated. 6. Clostridia overgrowth. They produce dopamine in the gut and it is absorbed. 7. Subclinical PKU enhances dopamine levels. One suffering high dopamine should test for PKU. 8. Amphetamines and cocaine greatly increase dopamine levels. Addicts are self-medicating. 9. Excitotoxic conditions tend to diminish GABA. The tetanus virus inhibits GABA. A cautious supplementation of GABA may be indicated. 10. Phenolics prolong the life of and intensify cellular responses to catecholamines (epinephrine, norepinephrine, etc.). They each act as cardiac stimulants. Nicotine (and probably caffeine) was observed to have a pronounced effect on biological membranes, that is, it increases the permeability of these membranes to certain pharmacologically active substances, such as norepinephrine, epinephrine, dopamine, etc. Peristalsis is increased in the intestine and distribution of blood is altered by these phenolics because of sensitizing smooth muscles to epinephrine, norepinephrine, and other physiological stimulants. This is particularly vital to those diagnosed as PST. There must be an aggressive effort to " unload the donkey " . Love, Willis I came across these bits of information that offer a new insight into controlling dopamine without drugs. If you wish, we can talk about it. (Some of this is a repeat of some of the above.) >>>Experiments on mice at Massachusetts General Hospital showed that caffeine could maintain levels of dopamine in the brain, a neurotransmitter that allows brain cells to communicate.>>> Additionally: >>>Dopamine and norepinephrine levels can be raised by eating a high protein meal and by using a supplement of the amino acid phenylalanine or tyrosine. >>> It would appear that one should avoid caffeine and high protein meals or dopaminergic supplements if taking dopamine antagonists like Zyprexa, or Risperdal. A lack of zinc (a widespread lack among us) will cause over-activity of these catecholamine neurotransmitters (dopamine, epinephrine, and norepinephrine). >>>Citation: Faro LR, do Nascimento JL, Alfonso M, et al. Protection of methylmercury effects on the in vivo dopamine release by NMDA receptor antagonists and nitric oxide synthase inhibitors. Neuropharmacology. 2002 Sep42(5)612-8. PMID:11985818. Abstract: The possible protective effects of NMDA receptor antagonists dizocilpine (MK-801) and D(-)-2-amino-5-phosphonopentanoic acid (AP5), and nitric oxide synthase (NOS) inhibitors L-nitro-arginine methyl ester (L-NAME) and 7-nitro-indazol (7-NI) on the methylmercury (MeHg)-induced dopamine (DA) release from rat striatum were investigated using in vivo microdialysis. Intrastriatal infusion of 400 microM or 4 mM MeHg increased the extracellular DA levels to 1941+/-199 and 7971+/-534% with respect to basal levels. Infusion of 400 microM or 4 mM MeHg in 400 microM MK-801 pretreated animals, increased striatal DA levels to 677+/-126 and 2926+/-254%, with respect to basal levels, these increases being 65 and 63% smaller than those induced by MeHg in non-pretreated animals. Infusion of 400 microM or 4 mM MeHg in 400 microM AP5 pretreated animals, increased striatal DA levels to 950+/-234 and 2251+/-254% with respect to basal levels, these increases being 51 and 72% smaller than those induced by MeHg in non-pretreated animals. Infusion of 400 microM MeHg in 100 microM L-NAME or 7-NI pretreated animals, increased the extracellular DA levels to 1159+/-90 and 981+/-292%, with respect to basal levels, these increases being 40 and 50% smaller than those induced by MeHg in non-pretreated animals. In summary, MeHg acts, at least in part, through an overstimulation of NMDA receptors with possible NO production to induce DA release, and administration of NMDA receptor antagonists and NOS inhibitors protects against MeHg-induced DA release from rat striatum. >>> Apparently, mercury can be a cause of excess dopamine activity. Many drugs control " excess " dopamine, whether Ritalin for ADHD or Zyprexa for psychosis. Unfortunately, they have horrendous side effects. Nutrients can be balanced by avoiding certain substances or by supplementing the right natural-food substances, without the side effects. This from Dr. Wm. Walsh of Pfeiffer Treatment Center is vital to understanding this: Choline adds methylation to DNA and would seem the " right " thing for building acetylcholine to balance the effects of dopamine. This letter shows why this is not necessarily true: Kathy, The benefits for choline are very significant for overmethylated persons, but can harm undermethylated persons. This seems counter-intuitive since choline enhances methylation. Here’s the reason: Choline supplements increase the production of acetylcholine, a dominant neurotransmitter in the brain. Acetylcholine is anti-dopaminergic, meaning it reduces brain dopamine levels. Undermethylated persons tend to be depressed in dopamine & the net effect of choline is to make it worse. We learned this the hard way in our early clinical practice – Undermethylated patients had nasty side effects from choline, but the overmethylated persons thrived on it. We now give DMAE to all overmethylated persons --- Choline can’t pass the blood/brain barrier, but DMAE readily passes into the brain. DMAE is a “vitamer” that converts to choline, and helps reduce excess dopamine. This is especially potent in helping overmethylated ADHD space cadets. There is a published study that indicates DMAE is more effective than Ritalin for ADHD and LD kids. Bill Walsh, MD, Pfeiffer Treatment Center Overmethylated, according to other communications with Dr. Walsh comprise about 15% while undermethylated comprise about 55% of patients. That leaves about 30% " normal " . Bolte notes that tetanus infection of the intestines leads to the formation of toxic compounds called phenols. As a corrosive substance, phenol (also known as carbolic acid) denatures proteins and generally acts as a protoplasmic poison. Studies of autistic individuals have detected markedly elevated levels of the phenolic metabolite of tyrosine (precursor of dopamine) called 3-(3-hydroxyphenyl) - 3-hydroxypropionic acid (HPHPA). Several autistic children with high HPHPA levels, " have shown a significant reduction in stereotyped behaviors when treated with antimicrobials effective against intestinal Clostridia " -a genus of bacteria that includes tetanus. " When certain bacteria of the CLOSTIRIDUM family (genus) are present in high numbers, phenylpropionic acid or 3-hydroxytrosine may be formed in the intestinal tract. Either of these compounds may then be converted to 3-hydroxphenyl-propionic acid that is, in turn, converted to HPHPA by the enzymes in the human mitochondria that break down fatty acids " - Shaw, Great Plains Laboratory. " We have noticed that the molar ratio of the urinary concentration of the dopamine metabolite homovanillic acid (HVA) to that of the epinephrine/norepinephrine (adrenaline/noradrenaline) metabolite vanillylmandelic acid (VMA) in urine is commonly elevated when HPHPA is elevated. This appears to indicate that a by-product involved in the formation of HPHPA likely inhibits the conversion of dopamine to norepinephrine, leading to relative dopamine excess. Animal studies indicate that dopamine neurons mediate behaviors such as hyperactivity and stereotypical behaviors common in autism. Of course, the drugs such as the phenothiazines and Haloperidol (and Risperdal), commonly used to treat autism and schizophrenia, are well known to block the action of excessive dopamine at the receptor level " -Biological Treatments for Autism and PDD, Wm. Shaw. It is noted that excess dopamine contributes to tics, OCD, and Exposure Anxiety that keeps the Autistic child in constant fight-or-flight mode. Additionally, phenolics prolong the life of and intensify cellular responses to catecholamines (epinephrine, norepinephrine, etc.). They each act as cardiac stimulants which accounts for the accelerated pulse that Dr. Arthur F. Coca so wisely deduced was symptomatic of an allergenic response. Nicotine (and probably caffeine) was observed to have a pronounced effect on biological membranes, i.e., it increases the permeability of these membranes to certain pharmacologically active substances, such as norepinephrine, epinephrine, dopamine, etc. Peristalsis is increased in the intestine and distribution of blood is altered by these phenolics because of sensitizing smooth muscles to epinephrine, norepinephrine, and other physiological stimulants. There is evidence for increased entry of potassium ions into the cell under the influence of epinephrine. This could account for the electrolyte imbalances and water retention (edema) noted in allergies. Now the $64.00 question is, what raises HPHPA and interferes with the neurotransmitters? That is a well-known answer. It is from the amino acid phenylalanine! Now, why would this essential amino acid be a problem? Two reasons: 1) you inherited a problem with metabolizing it called Phenylketonuria (PKU). This is a condition tested for today at birth, and if found, a diet free of phenylalanine is prescribed, but it is notorious that the guidelines for treating what I will call subclinical phenylketonuria is allowing many to have the problem without being treated. This could be you. 2) Clostridia overgrowth. When these are present in high numbers, the phenylpropionic acid or 3-hydroxytyrosine may be formed by these bacteria from phenylalanine in the intestinal tract. What is the chance you have clostridia? You might want to have an OAT and a stool test by Great Plains Laboratory to determine if you have the gut problem, and you could have your GP run a test for Phenylketonuria. If one or both of these prove to be a cause of high dopamine, then you are drug free! If your PKU test shows a value 5 or higher treat for PKU (restrict phenylalanine). If suffering Clostridia, kill them off. The children treated for clostridia (usually with Flagyl™) become more sociable, speak more, improve their eye contact, and are less hyperactive and hypersensitive. It should be noted that very high doses of L. Acidophilus GG is usually equally effective as metronidazole (Flagyl™). Additionally, Flagyl™ has a lot of side effects, and can upset the ecological balance in the gastrointestinal tract and lead to a yeast overgrowth. Dr. Shaw warns that the die-off effect can be even more severe than that of Candida. Some combination of AlkaSeltzer Gold™, bentonite clay, and charcoal, should be used to minimize the die-off effect and protect from damage. Bolte adds, " Parents also noted that regression occurred very quickly " after treatment was discontinued. Given these findings, Bolte says, " Parents, doctors, and researchers must combine efforts to determine if some people diagnosed as autistic are actually suffering from unrecognized forms of sub-acute tetanus. " This is very significant to that large block of children who do not handle phenol well (PST). The use of ORGANIC ACID TESTING (OAT) can provide a valuable tool guiding therapy so that harmful microorganisms may be eliminated before treatments with amino acids like phenylalanine that might actually cause neuropsyciatric symptoms to worsen. It is most interesting to note that phenol poisoning, as suffered by the PST child, deadens the nerves endings much as does aspirin (a phenol), thereby masking pain. In addition, she notes, inhibitory neurons that release the neurotransmitter GABA are a preferred target for tetanus neurotoxins-and the Purkinje cells of the cerebellum, that often appear highly abnormal in autistic individuals, are inhibitory neurons that release GABA. Additionally, GABA is reported to stimulate the brain to release human growth hormone (HGH), and to stimulate the anterior pituitary function. Glutamine, a precursor of GABA, readily passes through the blood-brain b arrier and is a good supplement to take if one wants to increase brain levels of GABA, since glutamine, once it is in the brain, converts into GABA, however, excess glutamine can become excitotoxic. Due to that possibility, GABA may be the preferred supplement. GABA activity is found in glands controlled by the sympathetic nervous system, namely: the pancreas and thymus. It is estimated that 30-40% of all CNS neurons utilize GABA as their primary neurotransmitter! Glutamic acid decarboxylase (GAD) the active enzyme capable of decarboxylating glutamate to GABA requires pyridoxal 5-phosphate (P5P) as cofactor. This enzyme found in the liver is often the target of autoimmune attack in type I diabetics and when inhibited, can lead to excitotoxicity from unused glutamate. When there is not enough GABA a person can have a seizure because receiving neurons can be flooded with signals that say, " pass on this message. " A different type of neurotransmitter that promotes message transfer triggers the " go " messages. The charged signals they set off are positive. This time, more positively charged sodium particles (Na+) enter the neuron, which tells the receiving neurons to pass on the message. Valproic Acid (Depakote™), on the other hand, blocks GABA transaminase activity, thereby elevating GABA levels, thus alleviating seizures. Why depend on a drug that robs the body of L-carnitine and folic acid, and probably vitamin E and alpha-ketoglutaric acid, when GABA can be increased nutritionally with glutamine, zinc, and P5P (or GABA)? Further, Depakote™ (Epilum) is a bad choice of anticonvulsants due to the risk of fatal hepatotoxicity, and it acts on the metabolic pathways, which could further lower the platelet levels. The hepatotoxicity is probably due to valproate-induced carnitine deficiency. Drug induced tremors and tics are common, and Depakote™ can cause them. To prevent, use at least 333 mg each of vitamins C and niacinamide, and 66 mg each of vitamins B6 and E with a good broad-based, vitamin-mineral supplement. In one ten-year study, not a single case occurred! If already suffering the devastating effects of this doctor-induced condition, use 5 to 10 times as much, and pray. I believe Ambrotose® and PhytoAloe®, and PLUS by Mannatech, Inc. would be mandatory. Of course, when using Depakote™, supplement Carnitine and folic acid also. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Dopamine increases proportionately to the amount of stress. The higher the adrenaline level, the greater the increase in dopamine. Serotonin also increases. Dopamine and serotonin decrease during partial, toxic withdrawal states. But as long as caffeine remains in the toxic body, neurotransmitters never adjust to the victim's natural state. Caffeine Toxicity is known to cause excitement, agitation, restlessness, shifting states of consciousness, and toxic psychosis (10), mimicking amphetamine psychosis. Allergic individuals may be erroneously diagnosed, medicated, and lost in a dark disturbed world, until death. Adenosine receptors are blocked by caffeine (11,16), maintaining neuronal firing. Persons remain excited and often euphoric. Caffeine toxicity may be mistaken for bipolar disorder (1,12). Symptoms include: chattiness, repetitive thought and action (resembling obsessive compulsive disorder, OCD), restlessness, psychomotor agitation, alternating moods, anger, impulsiveness, aggression, omnipotence, delirium, buying sprees, lack of sexual inhibition, and loss of values. Allergy can mimic Attention Deficit Disorder (ADD) (13). As far back as 1902, T. D. Crothers noted that many caffeine consuming children " exhibit precocity " and " functional exaltation " (14). Caffeine poisoning may also resemble schizophrenia. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>.. dopamine Dopamine is a chemical naturally produced in the body. In the brain, dopamine functions as a neurotransmitter, activating dopamine receptors. Dopamine is also a neurohormone released by the hypothalamus. Its main function as a hormone is to inhibit the release of prolactin from the anterior lobe of the pituitary. Dopamine can be supplied as a drug which acts on the sympathetic nervous system, producing effects such as increased heart rate and blood pressure. However, since dopamine cannot cross the blood-brain barrier, dopamine given as a drug does not directly affect the central nervous system. To increase the amount of dopamine in the brain of patients with diseases such as Parkinson's disease, a synthetic precursor to dopamine such as L-DOPA can be given, since this will cross the blood-brain barrier. (DMAE would be contraindicated for it will cross the barrier and generate acetylcholine.) Biochemistry Dopamine molecule Enlarge Dopamine molecule Dopamine has the chemical formula (C6H3(OH)2-CH2-CH2-NH2). Its chemical name is 4-(2-aminoethyl)benzene-1,2-diol and it is abbreviated " DA. " As a member of the catecholamine family, dopamine is a precursor to epinephrine (adrenaline) and norepinephrine (noradrenaline) in the biosynthetic pathways for these neurotransmitters. Arvid Carlsson won a share of the 2000 Nobel Prize in Physiology or Medicine for showing that dopamine is not just a precursor to these, but is a neurotransmitter as well. Dopamine is synthesized in the body (mainly nervous tissue and adrenal glands) by the decarboxylation of DOPA by aromatic-L-amino-acid decarboxylase. In neurons, dopamine is packaged after synthesis into vesicles, which are then released in response to the presynaptic action potential. The inactivation mechanism of neurotransmission are 1)uptake via a specific transporter; 2) enzymatic breakdown; and 3) diffusion. Uptake back to the presynaptic neuron via the dopamine transporter is the major role in the inactivation of dopamine neurotransmission. The recycled dopamine will face either breakdown by an enzyme or be re-package into vesicles and reused. Functions of Dopamine in the Brain Role in Movement Dopamine is critical to the way the brain controls our movements and is a crucial part of the basal ganglia motor loop. Shortage of dopamine, particularly the death of dopamine neurons in the nigrostriatal pathway, causes Parkinson's disease, in which a person loses the ability to execute smooth, controlled movements. Role in Cognition and Frontal Cortex Function In the frontal lobes, dopamine controls the flow of information from other areas of the brain. Dopamine disorders in this region of the brain can cause a decline in neurocognitive function, particularly those linked to memory, attention, and problem solving. This function is particularly related to the mesocortical dopamine pathway. Role in Pleasure and Motivation Dopamine is commonly associated with the 'pleasure system' of the brain, providing feelings of enjoyment and reinforcement to motivate us to do, or continue doing, certain activities. Certainly dopamine is released (particularly in areas such as the nucleus accumbens and striatum) by naturally rewarding experiences such as food, sex, use of certain drugs and neutral stimuli that become associated with them. This theory is often discussed in terms of drugs (such as cocaine and amphetamine) which seem to directly or indirectly related to increase dopamine in these areas, and in relation to neurobiological theories of addiction, which argue that these dopamine pathways are pathologically altered in addicted persons. The mechanism of cocaine and amphetamine is different. Cocaine is acting as dopamine transporter blocker to competitively inhibit dopamine uptake to increase the lifetime of dopamine in synapse, while amphetamine is acting as a dopamine transporter substrate to competitively inhibit dopamine uptake (sic) and increase the dopamine efflux via dopamine transporter. However, the idea that dopamine is the 'reward chemical' of the brain now seems too simple as more evidence has been gathered. Dopamine is known to be released when unpleasant or aversive stimuli are encountered, suggesting that it is not only associated with 'rewards' or pleasure. Also, the firing of dopamine neurons occurs when a pleasurable activity is expected, regardless of whether it actually happens or not. This suggests that dopamine may be involved in desire rather than pleasure. Drugs that are known to reduce dopamine activity (e.g. antipsychotics) have been shown to reduce people's desire for pleasurable stimuli, despite the fact that they will rate them as just as pleasurable when they actually encounter or consume them. It seems that these drugs reduce the 'wanting' but not the 'liking', providing more evidence for the desire theory. Other theories suggest that the crucial role of dopamine may be in predicting pleasurable activity. Related theories argue that dopamine function may be involved in the salience ('noticeableness') of perceived objects and events, with potentially important stimuli (including rewarding things, but also things which may be dangerous or a threat) appearing more noticeable or more important. This theory argues that dopamine's role is to assist decision making by influencing the priority of such stimuli to the person concerned. Dopamine and Psychosis Disruption to the dopamine system has also been strongly linked to psychosis and schizophrenia. Dopamine neurons in the mesolimbic pathway are particularly associated with these conditions. This is partly due to the discovery of a class of drugs called the phenothiazines (which block D2 dopamine receptors) that can reduce psychotic symptoms, and partly due to the finding that drugs such as amphetamine and cocaine (which are known to greatly increase dopamine levels) can cause psychosis. Because of this, all modern antipsychotic medication is designed to block dopamine function to varying degrees. See the article on the dopamine hypothesis of psychosis for a wider discussion of this topic.
