Everyday exercise Can lower risk of Alzheimer's disease

University of California, Los Angeles said:"Grey matter houses all of the neurons in your brain, so its volume can reflect neuronal healt." Alzheimer's disease are the most common early symptom is difficulty in remembering recent events (short-term memory loss).

As the disease advances, symptoms can include problems with language, disorientation (including easily getting lost), mood swings, loss of motivation, not managing self care, and behavioural issues. The disease process is associated with plaques and tangles in the brain. Exercise can increase the level of grey matter volume in key brain areas which are responsible for memory, enabling the active adults to protect their brain from cognitive decline.

People with highest calorie expenditure had larger grey matter volumes in key areas on initial brain scans and were half as likely to have developed Alzheimer's disease five years later according to the findings. Mr Raji also said that "Rather than wait for memory loss, we might consider putting the patient on an exercise programme and then rescan later to see if there are any changes in the brain." the team examined the data obtained over five years from nearly 876 people 65 year or older participating in the multicenter Cardiovascular Health Study according to the Journal of Alzheimer's Disease.
