INSIGHT

Chemical Changes Affect Cognitive Function

  • Brain chemical drops in dopamine and acetylcholine affect motivation and focus with age. - These changes alter behavior, making older adults more risk-averse and slower to recall memories.
INSIGHT

Wisdom and Emotional Control Improve

  • Despite cognitive declines, vocabulary and language skills often improve with age. - Older adults enhance emotional control by focusing more on positive information and less on negative.

Brain Scaffolding Maintains Function

  • Older brains show less activity in some regions but compensate by recruiting others, a concept called scaffolding. - This adaptive process helps maintain cognitive function despite aging-related declines.
