Guest guest Posted March 12, 2005 Report Share Posted March 12, 2005 Hi Gerard, The one cited study was published in the year 2001, and the other in 2003. Consensus in 2005 seems to be that BPD may result from either genetic or environmental factors, or a combination of both. In other words, the BP's brain may be mis-wired (ie, genetic/heredity) influence; and, BPD may result from an invalidating home environment, childhood abuse, trauma, & etc (ie, environmental factors). As much as we'd like to know the answers, it really is too soon. Research studies are only now beginning to shed light on the etiology of this terrible, complex, mental disorder. Historically: 1980 - BPD was admitted to the DSM 1989 - Kreisman's book, " I Hate You - Don't Leave Me " appeared 1995 - The first WelcomeToOz lists for NonBPs were started 1998 - " Stop Walking On Eggshells " was first published 2000 - UBM by Lawson was published 2002 - SWOE Workbook was published 2003 - Roth & Friedman's book, " Surviving A Borderline Parent " was published BPs, NonBPs and KOs need to have patience while reading, studying, and learning about everything that is happening research-wise related to BPD.

Guest guest Posted March 12, 2005 Report Share Posted March 12, 2005 I'll apologize ahead of time but, what its just dumb luck that some astonishingly high precentage of these folks Do have abuse in their background? Sorry but I think this is western medicine running itself amuck yet again. The abuse may change the chemistry or like alcholism you can go back to a defective gene but something has to trigger the defective gene (in my oinion). Hey if they can come up with a chemical to make these folks " right " bless them but ignoring the abuse is not a great idea again in my opinion.

Guest guest Posted March 12, 2005 Report Share Posted March 12, 2005 Unfortunately I guess, I have a degree in statistics, and I checked more than once to make sure I was not crazy,but yep, I read there were 15 people in the BPD group and 15 in the normal group. Uhh - sorry, but that is a very, very, miniscule sample. You can't make ANY kind of generalization from that. A study like that could only give you a possible idea to do a bigger study, but nope - bad practice to make generalizations from something like this. Of course this is why I hate reading studies in the psych field - many of them are done quite sloppily. It's bad enough when you come across it in the hard science field. If you ask me, their conclusions section does not make complete sense. Of course neither does the Results, really. Their methods section kind of sucks. I think a 9th grader could do better on that one, even. Do these people really have a degree in something? Sorry 'bout that - just really irks me because I know sorry research when I see it and I know people tend to make generalizations about stuff from this kind of next to garbage and it's even worse when they report junk on the news and so everyone thinks it's true just because it's on the news. I think if this were to be done halway properly they need to get actual neurologists involved.

Guest guest Posted March 13, 2005 Report Share Posted March 13, 2005 Hi Larry, There is scientific research done towards abuse of bp's in their background, namely 'Memories of abuse in borderline patients: True or false ? ' (1995, J. Paris, Harvard Review of Psychiatry, 3, 10-17.) Paris summerizes the results as follow: 1/3 make no mention of traumatic antecedents 1/3 report annoying events in their youth of relative lenient character 1/3 report very radical experiences in their youth The query is: can the stories of bp's about their youth fully be trusted ? The characteric feature pre-eminently by bp's is their impulsivity. It cannot be dismissed that bp's also set about it the impulsive way when they have to answer queries about their youth. That's why the following advice of Paris to therapists who treat bp's: 'Given the problems concerning the validity of repressed memories in BPD, therapists would be best advised to treat recovered memories of abuse with respectful skepticism.' If this cautiously starting point do hold for the clinic, than do hold it a fortiori/all the more reason for KO's and....the courtroom !

Guest guest Posted March 13, 2005 Report Share Posted March 13, 2005 Thanks for posting. I am not a big fan of Roseaane but, she had a comment on the question, have you been sexually abused. Her contention which, I sadly subscribe to is: Yes or, I don't know! I concur that anything coming out of the mouth of a BP at BEST is suspect. Secondly with repressed memories its ANYBODY's guess. I can tell you from my own PERSONAL exoperience that just Friday I had new information come up relative to my abuse. There are some on here suggesting (?) " programming " and mind control. I am new enough here to not know the context of how that is being refferenced. Do they mean conscious mind screwing with true programing or is that just a consequence of a BP's beahvior? I don't know and I am not suggesing a judgement on my part either way. For MY experience I had DELIBERATE mind manipulation AND programming at the hands of some VERY able people via a cult while I was a toddler. Some of it multiple levels deep which came to the surface Friady. So questionaires in my opinion might not even be worth the paper they are wirtten on. I just don't subscribe to theories that people get " invloved " in seriously dysfunctional behavior(s) because mom did or didn't make them eat brocolli one night for dinner. I don't subscribe to theories that people make bad choices or happen to be this way. I think people for the most part are born good (with obvious exceptions of crack babies etc) and that they didn't wake up when they were 4 and go I can screw up my life or someone else's by drinking too much or whatever. There is just way to much " dumb luck " that the reported abuse levels in people with BPD is way to high. And even if you don't buy into that look at the behaviors they engage in and that tends to roll back to LOGICAL forms of abuse that destroyed those boundaries. It strikes me that in the very brief time I have been on the BP lists that the level of extra sexual relationships is dispraportinate to the general population. I have no clue as to why these things go the way they do but it strikes me that society is having a tough time owning that they are VERY seriously abusing their children. As has already been posted - the: this will hurt you more than it will be but its for your own good, just ain't cutting it. Its ABUSE the human form can't deal with it and sadly, very sadly (I am in one of my more compassionate moments) some folks adaption is BPD. Hey its just one more victims opinion, that GLADLY didn't compensate with BPD!

Guest guest Posted March 15, 2005 Report Share Posted March 15, 2005 Hi Theresa, I think your conclusion is not fair. We have to realize that the Methods that the -biological- psychiatrists/researchers has used in this case was 'functional Magnetic Resonance Imaging',(MRI-scan). MRI is an important research instrument. With MRI it is possible to make an image of the brain of living humans. In that manner you can get an striking clear image of the living brain. The MRI-scan is through that very suitable to trace distinct illnesses in the brain. Until recently it has not been possible to test hypothesis in the brains of living humans. MRI is very expensive. The number of 15 BP's and 15 Nonbp's is, I think, acceptable in consideration to the mentioned RESULTS and the CONCLUSIONS of this research. A scientist have not to search further for the same outcome he already has.

Guest guest Posted March 15, 2005 Report Share Posted March 15, 2005 My point was just that they should not sound so much like they are generalizing the results with such a small sample size. To me, it sounded like they were a little too conclusive. In the results when they say " significantly greater " what does that mean? They don't say. Significantly greater by how much? With the small sample size the power of the study is not going to be strong enough to make a statistical significance so that is why I wonder why they say significantly greater. What is their p value? What is the power of the study? How do they determine significance? HOw did they even determine their sample size? This kind of thing needs to be mentioned at least in their methods section. Again, this kind of study can only point to further research on a much larger scale as in this study can only be used to form a hypothesis. It cannot at all be used as a cause-effect relationship. Statistical laws are unfortunately not empathitic to the fact that MRIs and such tests are very expensive. To have an appropriate power of a study, a sample size has to be appropriate, so this type of study does need to be done on a much larger scale to show there in fact the result the researches saw in the smaller study and not due to chance or some confound factors or something else . When you say, " A scientist have not to search further for the same outcome he already has, " that's not what you would call good scientific method. In the past things have been held as scientific theory for years and years and then several years down the road someone proved it wrong. Look at how long spontaneous generation lasted, for instance.

Guest guest Posted March 16, 2005 Report Share Posted March 16, 2005 The abstract on the list summarizes the main points: BACKGROUND, METHODS,RESULTS and CONCLUSION of the scientific article (Biol Psychiatry 2003 Dec 1;54(11):1284-93, comprises ten pages) Statistics are facts which are obtained from analyzing information expressed in numbers, for example information about the number of times that something happens. In this study, we talk about, came the information from medical scans. So as, if a pregnant woman has a scan, a machine using sound waves produces an image of her womb on a screen so that the doctor can see if her baby is developing normally. The hypothese in this study was: 'amygdala hyperreactivity contributes to hypervigilance, emotional dysregulation, and disturbed interpersonal relations in BPD'. MRI-scans showed sygnificantly greater left amygdala activation by BP's (by examining 15 BP's and 15 Nonbp's). For the purpose of this research (to refute the hypothese) is that enough, the hypothese is not refuted, and the pictures can indeed be used as probes to study the neuropathopsysiologic basis of borderline personality disorder. In statistics the validity of the measuring-instrument is very important: do we really know -for 100 %- that we indeed measure with this instrument what we want to measure ? If you think that 15 + 15 + post scans, are not enough for this purpose how many scans are -according you- necessary ? 100 ? 1000 ? 100.000 ? Who will tell ? What is your measuring-instrument in this case ? We have to live with hypothesis until they are refuted, therefore scientists always have to test these hypothesis perhaps with new and better measuring-instruments and sometimes they have succes. This finding with MRI-scans opens a whole new perspective on the etiology of the bp-disorder.

Guest guest Posted March 16, 2005 Report Share Posted March 16, 2005 It takes a rather complicated statistical process to figure out the appropriate samples size for the power of the study which is why researchers need to be careful with these things before getting too excited about results and which the average lay person cannot easily understand. It's not " according to me " but rather according to the laws of statistics. " Who will tell? " There is a way to tell and it takes a statistician to do so. It has nothing to do with me. But speaking with general experience, 15 pre and post are only enough to do an observational type study and give an interesting result which the researcher may take to mean they want to actually perform a larger study.

Guest guest Posted March 17, 2005 Report Share Posted March 17, 2005 If staticians indeed knew a way, as you said, to know how much MRI- scans 'should be' necessary to refute the hypothese, the hypothese was already -on that basis- refuted. Further research about the validity of the hypothese should not be necessary anymore. Also in this case, staticians are not able to predict how much MRI- scans 'should be' necessary to refute -if possible !- the hypothese, only God knows that, if he exist. Staticians are only able to analyze information expressed in numbers from the past. In some cases they can only -predict- a possible trend for the future. As you know: statistical results from the past are no garanty for the future. The results of this study, and the other study I mentioned (Am J Psychiatry 2001; 158:775-782), are indeed very interesting, especially for KO's, because: These results/findings opens a whole new perspective on the etiology of the bp-disorder: not traumatic antecedents, but a Genetic Rooted Neurochemical Defect is responsible for the symptoms.

Guest guest Posted March 18, 2005 Report Share Posted March 18, 2005 Hi Edith, As you say: " Consensus in 2005 seems to be that BPD may result from either genetic or environmental factors, or a combination of both. " So: BPD may result from: 'either, or, or a.' The query is which one of this three possibilities results to BPD ?

Guest guest Posted March 18, 2005 Report Share Posted March 18, 2005 Hi Edith, As you say: " Consensus in 2005 seems to be that BPD may result from either genetic or environmental factors, or a combination of both. " So: BPD may result from: 'either, or, or a.' The query is which one of this three possibilities results to BPD ?

Guest guest Posted March 18, 2005 Report Share Posted March 18, 2005 You'd be surprised, actually, how much questionable stuff gets published. So, yes, to understan whether a study has any questionability to it, it does help tremendously for the reader to have a background in research including statistics. When researchers do not always set up their experiments properly, they are actually taking advantage of the reader who has no such background. Shouldn't be that way, but happens all the time.

Guest guest Posted March 19, 2005 Report Share Posted March 19, 2005 The scientific study we talk about (#36430) has Edith send to the list. She was/is professor of psychology at Cerritos College in Norwalk, California, see pade 5 + 6 of SWOE and moderator of this list. The truth of a scientific pronouncement is in principle free from the social positions and the meanings of scientists and is not the outcome but the direction-indicator touchstone of the social process that is called science. Either, for me the posts of Edith are always reliable. *wink* Gerard > > > > > > It is absolutely not necessary for readers of scientific article's to > > have a complete understand of a statician's job. > > > > Scientific article's are only published in scientific magazines after > > that other scientists have examined that article and after they have > > given their permission to publish that article.
