Nutritional modifiers of aging brain function: Increasing the formation of brain synapses by administering uridine and other phosphatide precursors

Brain phosphatide synthesis requires three circulating compounds: docosahexaenoic acid (DHA), uridine and choline. Oral administration of these phosphatide precursors to experimental animals increases the levels of phosphatides and synaptic proteins in the brain and per brain cell, as well as the numbers of dendritic spines on hippocampal neurons. Arachidonic acid (AA) fails to reproduce these effects of DHA. If similar increases occur in human brain, giving these compounds to patients with diseases – like Alzheimer’s disease – which cause the loss of brain synapses – could be beneficial.
