Exercise helps to prevent alzheimer's disease

There is much research going on regarding alzheimer's disease. Because it severely impacts the life of the patient and people around him or her, many studies are devoted to find out how we can prevent development of alzheimer's. A previous study revealed that diet may play an important role, but according to scientists from Kyoto University, exercise is actually more important.

Scientists set up experiments to assess the benefit of both diet and exercise when it comes to preventing alzheimer's. A mouse model was used to assess the effects, meaning three groups of mice were created: one group received a modified diet, another group was forced to exercise, while a third group had to endure both. They then looked at the tendency to develop a mouse variant of alzheimer's, which is induced by a genetic defect.

After analysing the effect of diet, exercise and the two combined, the scientists noted that increasing the level of exercise is much more beneficial than restricting access to unhealthy food. Exercise was deemed efficient in removing deposits of a protein called ß-amyloid in the brain, which eventually cause brain damage and induce typical alzheimer's symptoms. Providing the mice with a healthy diet in addition to exercise was not found to be much more efficient.

This study adds to the proof that exercise is healthy. Working out may prevent build-up of ß-amyloid and therefore delay the onset of alzheimer's. How effective this is in human beings is currently unknown, as the study was performed in a mouse model set to mimic the human situation. Also, no long-term studies were performed, which are required to assess the effect properly. Exercise has been shown to reduce the chance of breast cancer and increase your life span as well.
