TL;DR: Findings indicate that the &egr;2 and &egR;4 alleles have differential effects on cognitive aging, and that negative effects of &egra;4 may be partly mitigated by behavioral choices.

TL;DR: Hearing impairment is associated with accelerated cognitive decline with age, and should be screened for routinely, and higher education may provide sufficient cognitive reserve to counter effects of mild, but not more severe, hearing impairment.

TL;DR: The findings better characterize normal cognitive aging, a critical prerequisite for identifying individuals at risk for cognitive impairment, and lay the groundwork for future studies of health and behavioral factors that affect age-related decline in this cohort of older adults.

TL;DR: Moderate, regular alcohol intake was associated with better cognitive function relative to not drinking or drinking less frequently, which suggests that beneficial cognitive effects of alcohol intake may be achieved with low levels of drinking that are unlikely to be associated with adverse effects in an aging population.

TL;DR: It is found that memory-enhancing effects of psychostimulants observed at low doses are readily dissociable from their reinforcing and locomotor activating effects at high doses, and fear conditioning will be an especially fruitful platform for modeling the effects of psychoactive substances on long-term memory in drug development.
