Find all causes of Alzheimer's disease and a cure

There have been an abundance of preventative measures highlighted in the news about ways to ward off Alzheimer's Disease, everything from curry to crosswords.  And a recent piece in The New York Times suggested many such measures are not valid.  However, while the media can get carried away with some that are far-fetched, there is an accumulating and substantial evidence that suggests physical exercise lowers the risk of developing Alzheimer's.

Cure Alzheimer's Fund-affiliated researcher Sam Sisodia and colleagues have conducted mouse studies that support the anti-Alzheimer's benefits of exercise.

They have found:

• The positive benefits of exercise on cognition and prevention of age-associated neurodegenerative conditions, including vascular dementia and Alzheimer's disease, are well established.
• Exercise largely forestalls the onset of amyloid deposits in mice (amyloid deposits are the signature lesions of Alzheimer's).
• A number of genes are known to be "upregulated" (or turned on) in brains of exercised mice.  This information reveals that the protein products of these genes have a positive influence on decreasing amyloid deposition.
• Exercise is known to increase the production of neural stem cells and their neuronal differentiation in the hippocampus, a region critical for memory formation.
