Abstract [en]

Background: The association between serum total cholesterol (TC), lipid-lowering drugs and cognition in the elderly is currently controversial. Objective: To investigate the relationship between TC, lipid-lowering drugs and cognitive functions in non-demented elderly. Design and Setting: Participants of the Cardiovascular risk factors, aging and dementia (CAIDE) study were derived from random, population-based samples previously studied in 1972, 1977, 1982 or 1987. Analyses are based on 1382 non-demented participants re-examined in 1998 after an average follow-up of 21 years. Results: High midlife TC was associated with poorer late-life episodic memory and category fluency. TC decreased in most individuals over time. A more pronounced decrease was related to poorer late-life episodic memory and psychomotor speed, but not if subjects used statins. Conclusions: The TC-cognition relationship seems bidirectional. High midlife TC is associated with poorer late-life cognition, but decreasing TC after midlife may reflect poorer cognitive status. Statins may be beneficial for cognition in non-demented elderly.
