Pharmacological correction of CNS functional disorders and parkinsonian syndrome in old animals.

The effects of 2-ethyl-6-methyl-3-hydroxypyridine (3-HP) on age-related and alcohol-induced impairment of memory and learning were studied in rats and mice. 3-HP was found to accelerate the acquisition of the conditioned reflex of active avoidance and to improve the retention of the conditioned reflex of passive avoidance in old (24 months) rats. 3-HP consumption during chronic (5 months) alcoholisation improved learning ability and prevented lipofuscin accumulation in brain of ethanol-treated mice.
