Age-related changes in the acetylcholinesterase activity were measured in the hippocampus, brain stem and cerebellum of rats (aged 4, 8, 16 and 24 months). The age-dependent decrease in the enzyme activity first appeared in the hippocampus; the brain stem was affected later while the cerebellum remained unaffected. Centrophenoxine, usually considered as an ageing reversal drug and also regarded as a neuroenergeticum in human therapy, increased the acetylcholinesterase activity in the hippocampus of aged rats, the activity was also elevated in the brain stem but no in the cerebellum. The acetylcholinesterase-stimulating influence of the drug is likely to be implicated in the pharmacological reversal of the age related decline of the cholinergic system. This effect of the drug may also mediate its effects on cognitive and neuronal synaptic functions.
