Brain and exercise

"Could exercising regularly and not smoking help to delay dementia?" Scientific American, Dec. 2010.

We who are in the midst of dementia caregiving can no longer delay dementia for the person for whom we provide care, but we can support their overall health and we can take care of our own health. Research from Group Health Research Institute in Seattle has found in the brains of people with dementia evidence of very tiny strokes -- strokes so small they can only be detected after death. This leads researchers to consider whether dementia might be caused by the tiny strokes. At this point it is impossible to say if the tiny strokes cause dementia, co-exist with dementia or are unrelated. But, it may bring new treatment and prevention with early cardiovascular treatment to prevent the microinfarcts (strokes).
