High blood pressure linked to dementia risk

The American Heart Association (AHA) has suggested that high blood pressure, especially in middle age, is linked to certain forms of dementia.
A review of previous studies led AHA experts to conclude that high blood pressure “disrupts the structure and function of cerebral blood vessels”, which leads to damage to the white matter parts of the brain that are critical for cognitive function.
The research team is hoping to carry out further studies to establish whether treating high blood pressure, especially in middle age, can limit the risk of damage to cartain parts of the brain later on.
The findings come after UK research earlier this year that showed how over four million people showed a link between high blood pressure and the risk of vascular dementia.
Vascular dementia is the second most common cause of dementia after Alzheimer’s disease and is caused by a reduction in blood flow to the brain resulting from a stroke or damage to small blood vessels
