White matter hyperintesities are areas of the brain where damage has occurred to the neurons. These areas are associated with peri/menopausal hot flushes because the brain is starved of energy and is cannibalising itself for energy.
White matter hyperintesities are also associated with dementia and Alzheimer’s but recent research shows that exercise can help to reduce the risks of decreasing brain function:
“…as people age, the presence of Alzheimer’s-related brain changes increases—including the buildup of amyloid, slower breakdown of glucose by brain cells, shrinking of the volume of the hippocampus (central to memory), and declines in cognitive function measured in standard recall and recognition tests.
But they found that in people who reported exercising at moderate intensity at least 150 minutes a week, as public health experts recommend, brain scans showed that these changes were significantly reduced and in some cases non-existent compared to people who were not active. “The association between age and Alzheimer’s brain changes was blunted,” says Okonkwo, “Even if [Alzheimer’s] got worse, it didn’t get worse at the same speed or rate among those who are physically active as in those who are inactive.”
