Curry a cure for Alzheimer's Disease?

As much as I don't feel the need to promote the miracle that is curry any more than I already do, I read today in the Hindustan Times that a substance found in curry can prevent the onset of Alzheimer's Disease.

Alzheimer's is a progressive brain disorder that destroys a person's memory and ability to learn, reason, make judgments, communicate and carry out daily activities. It mainly affects people in the over 65 group, with the chances of someone suffering from it rising to 50 percent by the age of 85. It is caused by plaques or tangles of protein in or outside brain cells that build up over time. You can find out more about Alzheimer's at the Alzheimer's Association.

The substance curcumin, which gives curry its yellow pigment, was found by researchers at California University to inhibit the onset of these protein build-ups at least as effectively as other drugs already used to treat Alzheimer's.
