Well before signs of dementia trigger a diagnosis of Alzheimer's disease, a person's cholesterol levels may be a bellwether of amyloid plaque build-up in the brain, a new study finds. Long considered a reliable predictor of heart attacks and strokes, worrisome cholesterol levels may now raise concerns about dementia risk as well, prompting more aggressive use of drugs, including statins, that alter cholesterol levels. The current study does "not convincingly exclude the possibility" that taking statins might lower amyloid deposition, the researchers said.

Elderly people who have both mild cognitive impairment and a history of serious concussion showed higher amounts of the protein deposits associated with Alzheimer's disease , according to a new study. The results, published Thursday in the journal Neurology, suggest a potential link between a history of head trauma and later cognitive decline. Researchers at the Mayo Clinic in Rochester, Minn., enlisted 589 elderly residents of surrounding Olmsted County, beginning in 2004, and administered a battery of cognitive and memory tests, along with brain scans that reveal both structure and metabolic function.

Los Angeles County's mortality rate dropped 19% between 2001 and 2010, according to a new report from the Los Angeles County Department of Public Health. Data compiled for the report , which was released Monday, showed that death rates due to coronary heart disease fell 37% over that decade. Death rates due to stroke fell 35%. One ailment that bucked the trend was Alzheimer's disease, which saw death rates double, a sign of the aging population as well as increased awareness of the condition, the report noted.

Shortly before she entered graduate school at Johns Hopkins University in 1970, Candace Pert broke her back in a riding accident. Dulling the pain from her injury with morphine led her to speculate about how the drug exerted its effects on the brain. Her graduate advisor, neuroscientist Solomon H. Snyder, set her to searching for an insulin receptor and discouraged her from following her interest in morphine. According to Pert's account, he ultimately forbade her to attempt to explain morphine's mechanism of action.

The mounting problem of caring for an aging population isn't unique to the U.S., according to a new report from the coalition Alzheimer's Disease International. Around the world, about 101 million people ages 60 and older need special care today. By 2050, that number will increase to 277 million, report author and King's College London psychiatrist Dr. Martin Prince and collaborators wrote, noting that most long-term care for the elderly is targeted at patients who suffer from dementia -- and that those patients present a particularly difficult challenge for the care system.

New research finds that copper in amounts readily found in our drinking water, the foods we eat and the vitamin supplements we take likely plays a key role in initiating and fueling the abnormal protein build-up and brain inflammation that are hallmarks of Alzheimer's disease. While the mineral is important to healthy nerve conduction, hormone secretion and the growth of bones and connective tissue, a team of researchers from the University of Rochester Medical Center suggested that too much of it may be a bad thing, and they set about to explore copper's dark side.
