      Stress and Trauma Risk Factors for Alzheimer’s

      Researchers linked midlife stress and childhood trauma to an increased risk of Alzheimer’s disease and neuroinflammation. Analyzing 1,290 volunteers, researchers found that stressful life events, especially during midlife, correlate with higher levels of β-amyloid protein, crucial in Alzheimer's development, and that childhood stress is associated with later life neuroinflammation. Interestingly, the study also uncovered sex-specific effects, with stress leading to amyloid protein accumulation in men and brain atrophy in women.
