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. In autopsies on the brains of 774 men after their deaths, scientists found that those who took beta blockers to help control hypertension had fewer of the brain lesions and less of the brain shrinkage seen in Alzheimer's than men who took other types of blood pressure medications and those who left the condition untreated.

After sparking widespread comeback chatter last year with his album "The Bravest Man in the Universe," soul singer Bobby Womack has announced that he's experiencing early symptoms of Alzheimer's disease. "The doctor says, 'You have signs of Alzheimer's,' " Womack told the BBC's Gilles Peterson in an interview on the latter's Radio 6 program. "It's not bad yet, but it's gonna get worse. " Womack, 68, admitted that he's having trouble remembering things, including the name of Damon Albarn, who co-produced "The Bravest Man in the Universe" with XL Recordings chief Richard Russell.

A biological medication already widely used to treat plaque psoriasis may be able to slow the accumulation of amyloid plaques in the brain that are the hallmark of Alzheimer's disease, a new study has found. The same study found that in older mice with established Alzheimer's, this treatment approach, which suppresses the brain's immune reaction to beta amyloid, brought a marked improvement in cognitive function and may even halt or reverse early signs of Alzheimer's. The new study was published this week in the journal Nature Medicine.

Asserting "we are at an exceptional moment" in the hunt for an Alzheimer'sdiseasetreatment, National Institutes of Health director Dr. Francis Collins on Tuesday promised a raft of new research aimed at stopping and reversing the memory-robbing disorder by the year 2025. In unveiling a first-ever "national strategy" on Alzheimer's disease, Collins launched several new projects and clinical trials--including a whole-genome sequencing effort to identify genes that confer vulnerability to--or protection against-- Alzheimer's, and a trial to explore whether an inhaled form of insulin will slow progression of the disease.

There is no cure for Alzheimer's disease, and as far as treatment goes, the best doctors can do (for now) is try to slow its progression. Identifying people in the earliest stages of the disease - even before any symptoms appear - would thus be very useful. But how? By using MRI scans to measure the thickness of specific parts of the brain, that's how. A new study from the journal Neurology reports that an “AD signature” can predict which people with normal brain function are most likely to suffer cognitive decline in the relatively near future.

Pretty much everyone who wanders into Pat Summitt's office or visits her basketball practice these days has learned to fear the iPad. The coach keeps her tablet filled with brain-wrenching games. Crossword puzzles and Sudoku. Math quizzes and memory tests. "When people come by," said Tyler, her son, "she gets them to sit down and try one of those things. " It was seven months ago that doctors diagnosed Summitt with early-onset dementia, Alzheimer's type, an incurable brain disease that affects memory, thinking and behavior.
