A number of anatomic structures and endogenous substances are involved
in memory processes, which are also influenced by interdependent cere
bral activities. Age-related memory impairment (ARMI) documented by ps
ychometric tests capable of ruling out memory loss due to disease or m
edications is the result df normal age-related circulatory, energetic,
biochemical, and neuroinformational alterations, whose severity vary
widely across individuals. Passive preventive measures include elimina
tion of substances with adverse effects on neurons (tobacco, alcohol,
amnesia-inducing medications), appropriate nutrition, and treatment of
metabolic disorders (diabetes mellitus, hyperlipidemia), Active preve
ntive measures aim at stimulating cerebral function. Early detection a
nd evaluation of ARMI allows use of symptomatic drugs, including cereb
ral vasodilators, metabolism-enhancing agents, and psychostimulants, w
hich should be carefully selected based on their pharmacodynamic profi
le and the health status of the individual patient. Considerable hope
lies with molecules (antioxidants, gangliosides, nerve growth factor)
that selectively block the aging process.
