It has the makings of a science fiction movie: Zap someone's brain with mild jolts of electricity to try to stave off the creeping memory loss of Alzheimer's disease....

Beta blockers, a venerable class of blood pressure drugs that has fallen from favor in recent years, may help protect the aging brain against changes linked to Alzheimer's disease and other forms of dementia that rob memory and mental function, new research indicates.

Scientists have identified a new gene variant that seems to strongly raise the risk for Alzheimer's disease, giving a fresh target for research into treatments for the mind-robbing disorder.

The new class of drug, which can be taken orally, is designed to protect the brain by combating the damaging effects of inflammation. Results from early stage clinical trials have yet to be announced, but studies on animals suggest the therapy could be effective against a wide range of conditions which also include motor neurone disease and complications from traumatic brain injury.

Though current trials and several others about to begin probably will be too late to benefit Frost, research is showing the importance of early diagnosis. Once the process that destroys brain cells has begun, the disease is irreversible. But if researchers can find a way to catch it early and slow it down, they think they can prevent much of the worst damage.

Dr. Sujatha Reddy joins CNN's Fredricka Whitfield to discuss how drinking more coffee can help delay Alzheimer's.

Look for a fundamental shift in how scientists hunt ways to ward off the devastation of Alzheimer's disease - by testing possible therapies in people who don't yet show many symptoms, before too much of the brain is destroyed....

Would you go to the gym or pick up those free weights to prevent memory loss, sharpen your thinking, and protect you from dementia and Alzheimer's? New evidence suggests exercise is the best way to take care of your brain.

In some cases, Alzheimer's disease may in fact be the result of an infection, and may be even be transmissible, a new study in mice suggests.

Scientists are closing in on a long-sought goal: A blood test to screen people for Alzheimer's disease. An experimental test did a good job of indicating how much of the telltale Alzheimer's plaque lurks in people's brains, Australian researchers reported Wednesday. If the test proves accurate in larger studies, it could offer a way to check people having memory problems to see who needs more definitive testing for the disease.
