I'm a little late on this one (study was published in December 2010), but I want to cover it today because I feel this is very relevant to many people. This was a review on previous research and clinical trials that have evaluated nutritional ingredients in brain and cognitive function.
The lead researcher says, "the rates at which brain neurons form new dendritic spines and synapses depend upon brain levels of...uridine, DHA, and choline."
The researchers explain the brain of patients with Alzheimer's are deficient in DHA and choline, and previous experiments on animals treated with uridine, DHA, and choline increased quantity of synaptic membrane in the whole brain, while a human study showed improved memory.
Keep in mind that this study only looked at three compounds, but from my own research, there are a number of other good natural brain-health ingredients. Ingredients that can improve the quantity of acetylcholine (neurotransmitters), delay acetylcholine's degradation, or improve the conduction velocity of brain signals. That's beyond the scope of this post, but maybe I'll cover it one day.
