A new study suggests the aging brain is adapting rather than declining, according to the article.

Researchers report the brain undergoes a major biological shift between the ages of 50 and 75.

The findings challenge long-held assumptions about cognitive deterioration in older adults.

The article says brain immunity may undergo a major overhaul in midlife.

Scientists stress that these biological transitions are an entirely natural part of aging.

Older adults often remember fewer details, but researchers say that might actually be a good thing.

Memory shifts toward general concepts over exact details, which the article says helps prevent cognitive overload.

The work may help doctors tell normal brain changes apart from disease, the piece says.

Future trials will track these milestones and test how lifestyle changes affect midlife shifts.
