Regular exercise 'could prevent Alzheimer's brain injury'

Posted on 16 August 2011

Undertaking regular exercise could help those paying for care to stave off the brain damage seen in neurodegenerative conditions such as Alzheimer's disease, research has indicated.

Exercise taken before the onset of damage is able to modify the brain environment in order to protect neurons from severe injury, according to the study published in journal Brain, Behaviour and Immunity.

Mice that exercised regularly produced an immune messenger called interleukin-6 in the brain, which is believed to lessen the harmful inflammatory response to the damage, preventing the loss of function in the learning and memory region of the brain.

Dr Ruth Barrientos, of the University of Colorado, suggested: "Perhaps the greatest challenge with this line of research will not be more discoveries of compelling evidence of the anti-neuroinflammatory effects of exercise, but instead, getting humans to exercise voluntarily and regularly."

In other news, Lancaster University researchers believe a breakthrough medication for Alzheimer's disease could be as little as five years away.
