How does aging affect the brain?

Aging affects the brain by causing subtle structural changes like shrinkage in certain areas (frontal lobe, hippocampus) and reduced blood flow, leading to slower processing, attention issues, and mild memory recall difficulties, while vocabulary and reasoning often improve; these normal changes differ from severe cognitive decline like dementia, and the brain retains plasticity for learning new things, with lifestyle choices influencing brain health.

What age does your brain start to decline?

What's normal and what isn't? Cognition is the ability to learn, remember, and make judgments. It peaks at age 30. Starting in your 60s, you may notice normal cognitive aging when your brain's processing speed slows down.
