Cognitive decline is slower if you were born later in the 20th century

Takeaway

  • People born between 1921 and 1935 have better late-life cognitive performance and slower cognitive decline than their same-aged counterparts born two decades earlier.

Why this matters

    This study cohort is unique because it included racially and ethnically diverse people whose education ranged from 0–20 years; it reveals that sociocultural inequalities play a key role in the underlying mechanisms behind variations in cognitive aging and dementia.
