The effects of age on cognition and intelligence are related, at least in part, to vascular disease that selectively affects the
A) visual cortex.
B) level of the neurotransmitter serotonin.
C) density of brain white matter.
D) prefrontal brain.

Question

Quizplus · Accepted Answer

Vascular disease associated with aging can cause damage to the prefrontal cortex, which is involved in executive functions such as working memory, decision making, and planning. This can lead to declines in cognitive abilities, including intelligence. Research has shown that age-related declines in prefrontal function are associated with changes in white matter integrity, suggesting that vascular damage may affect the density of brain white matter as well. However, the other options (visual cortex and serotonin levels) are not as closely linked to age-related cognitive declines as the prefrontal cortex and white matter integrity.
