Using data collected from a long term study started over 60 years ago, Charles DeCarli and his research team has found a connection between brain health (injury to white matter) and blood pressure.
MRI imaging effectively showed 30 year olds with high blood pressure had similar brains to 40 year olds with normal blood pressure. Injury to white and grey matter in the brain increased as blood pressure increased.
The researchers speculated that high blood pressure which leads to arterial stiffness, reduced oxygen and nutrient flow to the brain.
