Narrator: This is Science Today. There's so much information coming out about new treatments and possible cures for Alzheimer's Disease that Carl Cotman, director of the University of California, Irvine's Institute of Brain Aging and Dementia, says the public needs help weeding out what's accurate and what's not.

Cotman: There's just not enough neurologists, psychiatrists and specialists to ever see the bulk of the people and so really, this has to be translated ultimately to family medicine. That's really where the working grassroots basis is for so much of the health care and the elderly today.

Narrator: There's also a need for more experimentation.

Cotman: What would happen if a person was on estrogen plus an ibuprofen plus an antioxidant? This is kind of an educational cycle. Some of these dietary interactions among the elderly are still fairly undescribed and unexplored and we're constantly asked by our families and patients, well, how much should we take? When should we take it? And you know sort of what's wrong but then you gotta figure out what's right for these individuals.
