Dmae - Dimethylaminoethanol - Deanol
What do you think of DMAE as nootropic? As a supplement is cheaper than others.
Memory and acetylcholine: http://www.ncbi.nlm.nih.gov/pubmed/19756528 2009 " In rat experiments, DMAE p-Glu increased the extracellular levels of choline and acetylcholine in the medial prefrontal cortex, as assessed by intracerebral microdialysis, improved performance in a test of spatial memory, and reduced scopolamine-induced memory deficit in passive avoidance behavior. Clinical study results show that scopolamine induced a memory deficit and that DMAE p-Glu produced a significant positive effect on scores in the Buschke test, as well as a slight but significant difference on choice reaction time.
These results indicate that DMAE p-Glu reduces the deleterious effect of scopolamine on long-term memory in healthy volunteers and suggest that DMAE p-Glu might be effective in reducing memory deficits in patients with cognitive impairment."
Mood: http://www.ncbi.nlm.nih.gov/pubmed/12844472 2003 " Both scores revealed a better mood for the active drug group thus corroborating the results from EEG analysis. Therefore the vitamine-mineral drug combination containing DMAE can be interpreted to induce a psychophysiological state of better feeling of wellbeing on both levels of analysis mood and electrical pattern of brain activity in subjects suffering from borderline emotional disturbance."
Memory: http://www.ncbi.nlm.nih.gov/pubmed/864168 1977 " The results thus suggest that although deanol may not improve memory, it may produce positive behavioral changes in some senile patients."
Acetylcholine: http://www.ncbi.nlm.nih.gov/pubmed/15164765 2004 " Dimethylethanolamine does not prevent liver failure in phosphatidylethanolamine N-methyltransferase-deficient mice fed a choline-deficient diet.
Mice that lack phosphatidylethanolamine-N-methyltransferase (PEMT) and are fed a choline-deficient (CD) diet suffer severe liver damage and do not survive.
We conclude that although PC and PDME exhibit similar physical properties, the three methyl groups of choline are required for hepatic function in mice."
Acetylcholine: http://www.ncbi.nlm.nih.gov/pubmed/512912 1979 " [2H6]Deanol was a weak competitive inhibitor of the high affinity transport of [2H4]choline, thus reducing the synthesis of [2H4]acetylcholine.
Treatment of rats with [2H6]deanol significantly increased the concentration of choline in the plasma and brain but did not alter the concentration of acetylcholine in the brain.
However, since [2H6]deanol did increase brain choline, it may prove therapeutically useful when the production of choline is reduced or when the utilization of choline for the synthesis of acetylcholine is impaired."
