Patient-Friendly Explanation

Dementia is a decline in memory, thinking, and daily function, and carrying excess weight in mid-life is linked to a higher chance of developing it later. Obesity raises the risk through high blood pressure, diabetes, and inflammation, which can damage blood vessels and brain tissue over time. Keeping a healthy weight in midlife is one way to help protect long-term brain health.

Clinical Definition

Obesity in midlife is a recognised modifiable risk factor for all-cause dementia and Alzheimer disease. Proposed mechanisms include chronic neuroinflammation, insulin resistance, cerebrovascular disease, and adipokine dysregulation leading to hippocampal atrophy and impaired neurogenesis. Longitudinal studies show higher midlife BMI is associated with an increased hazard of late-life dementia, independent of comorbid diabetes.
