Prevent Alzheimer's? No evidence you can: panel
| Reuters: "Fish oil, exercise and doing puzzles may all be good for the brain but there is no strong evidence that any of these can prevent Alzheimer's disease, an expert panel concluded on Wednesday.

Nor can any other supplements, drugs or social interaction, the independent panel meeting at the National Institutes of Health outside Washington concluded.

The group of experts looked at the dozens of studies that have suggested ways to prevent Alzheimer's -- a devastating and incurable breakdown of the brain -- and found none were strong enough to constitute proof."
