Study identifies specific brain regions damaged by high blood pressure linked to dementia

For the billion people living with high blood pressure, the threat has long extended beyond the heart — but the path from elevated pressure to lost memory remained poorly understood. An international research team, drawing on genetic and imaging data from 33,000 individuals, has now mapped nine specific regions of the brain's white matter where hypertension leaves its mark, quietly dismantling the architecture of thought, memory, and emotional regulation. Crucially, they found that it is systolic and pulse pressure — not diastolic — that drive this cognitive erosion, resolving decades of contr
