Guest guest Posted August 18, 2005 Report Share Posted August 18, 2005 Doing some research and this hit me as something you probably already know. Are these waves that are known as " autism-like spikes " that are often on the EEG reports of people with autism? 10. A number of different kinds of seizure like EEG activity have been reported in patients with lithium induced encephalopathy. These include " runs of periodic sharp waves ... triphasic complexes ... widespread slow activity alternating with runs of periodic sharp waves " ( and Kocen, 1988); " increased slow waves, sharp waves and high voltage activity ... sudden appearance of high voltage paroxysmal groups with sharp waves and spike wave like activity " (Itil et al., 1971); " pseudo periodic discharges " (Prima Vera et al., 1989); " increased theta and delta especially in frontal areas with triphasic waves and sharp waves in frontal areas " (Broussolle et al., 1989). The possibility that lithium induced seizure activity may contribute to the encephalopathic syndrome observed in lithium neurotoxicity is suggested by some observations on mental status changes in a series of patients with non convulsive status epilepsy. (Lee, 1985). http://psycprints.ecs.soton.ac.uk/archive/00000524/ Also, this study mentions inosital as a possible anti-convulsant. Know anything about that? I've been wondering if Allie's brain is having some abnomormal waves that might be getting her " stuck " in thoughts. One thing I thought about is increasing magnesium baths, now I'm thinking about boosting the inositol as well. Another thing, this study also mentions acetylcholine. Reminded me of www.megson.com study with urocholine. In the Megson study she states the urocholine stimulates post-synaptic cell membranse via receptors for acetylcholine. The first study I referenced states: et al. (1990) found that lithium increased both intracellular and extracellular evoked post synaptic potentials (EPSP) as measured in the mid portion of the stratum radiatum of region CA1 of hippocampus. While cholinergic agonists produced opposite (decremental) effects on these same evoked potential measures, lithium prevented the cholinergic effects ( et al., 1990). Excitatory effects of cholinergic agonists in brain depend primarily on inhibition of potassium currents in postsynaptic neurons (Krnjevic, 1993). Thus, the fact that lithium potentiates the epileptogenic effects of cholinergic agonists may be explained by its presynaptic effects. Does this mean that urocholine produces a decremental effects on the same evoked potentials that lithium increases? Doesn't that mean that this finding that cholinergic agonists do the opposite of what Megson found? Please explain in English. Bottom line, will lithium supps help Allie's brain function or send her into definite epileptic issues? TIA, Debi Quote Link to comment Share on other sites More sharing options...
