New research shows shrinking in the hippocampus of the brain could be a precursor to dementia. Researchers performed MRI scans on 142 patients -- 64 with Alzheimer's disease, 44 with mild cognitive impairment and 34 with no memory or thinking problems. They found that patients who did not have dementia at the beginning of the study, but had smaller hippocampal volumes and higher rates of shrinkage were two to four times more likely to develop dementia than those with larger volumes and slower...

Running errands, attending parties, and cheering on your favorite sports team, may actually help protect you from dementia, according to researchers. People who kept both a busy social schedule and were not easily stressed had a 50 percent lower risk of developing dementia compared with men and women who were isolated and prone to distress, said researchers. The findings were reported in the journal Neurology. "In the past, studies have shown that chronic distress can affect parts of the...

Researchers at Northwestern University in Chicago say they have found a critical way a man can transmit the HIV virus to a woman. The researchers showed that the HIV virus can penetrate a woman's normal, healthy genital tissue to a depth where it can gain access to immune cell targets. This is an unexpected and important result, principle investigator Thomas Hope said in a statement. We have a new understanding of how HIV can invade the female vaginal tract. Scientists had long believed...

By MARILYNN MARCHIONE By Marilynn Marchione The Associated Press CHICAGO A milder type of mental decline that often precedes Alzheimer's disease is alarmingly more common than has been thought , and in men more than women, doctors reported Monday. Nearly a million older Americans slide from normal memory into mild impairment each year, researchers estimate, based on a Mayo Clinic study of Minnesota residents. That's on top of the half-million Americans who develop full- blown...

A Canada-U.S. research team has solved a major genetic mystery: How a protein in some people's DNA guards them against killer immune diseases such as HIV. In an advance online edition of Nature Medicine, the scientists explain how the protein, FOX03a, shields against viral attacks and how the discovery will help in the development of a HIV vaccine. "HIV infection is characterised by the slow demise of T-cells, in particular central memory cells, which can mediate lifelong protection against...

NEW YORK (Reuters Health) - Behavioral problems and lower than average scores on tests measuring development and intellectual capacity are common in HIV-infected children, according to a report in the journal Pediatrics. HIV-infected children are at high risk for developing neurological and neurodevelopmental impairments, the authors explain, but the effect of HIV infection on specific behavioral issues is poorly understood. Dr. Molly L. Nozyce from the Bronx Lebanon Hospital Center,...

By Amy Norton NEW YORK -- Older women who say talk shows and soap operas are their favorite TV programs tend to score more poorly on tests of memory, attention and other cognitive skills, researchers reported Monday. That doesn't mean that daytime television is a brain drain, they say, since it's not clear that there's a direct relationship between the two. But the findings do point to some association between TV choices and intellectual function, and that could prove useful in evaluating...

Researchers studying the evolution of the human immunodeficiency virus (HIV) in the brain have found that the body's own defenses may cause HIV-related dementia. Publishing in the Sept. 2005 issue of the Journal of Virology, the researchers show that HIV in the temporal lobe mutates at a rate 100 times faster than in other parts of the body, triggering white blood cells to continually swarm to attack the infection. The associated overcrowding and inflammation appear to cause the dementia....

Washington -- By combing through dozens of Alzheimer's disease (AD) studies, psychologists have gained a clear picture of cognitive problems in people who will develop the degenerative brain disease. The meta-analysis reveals that people can show early warning signs across several cognitive domains years before they are officially diagnosed, confirming that Alzheimer's causes general deterioration and tends to follow a stable preclinical stage with a sharp drop in function. The findings...

INDIANAPOLIS "“ How can the U.S. health-care system and more specifically, primary care doctors - the physicians from whom older adults receive most of their care - prepare for the huge wave of dementia patients expected to engulf us in 2010, the year the baby boomers begin to reach 65? Researchers from the Indiana University School of Medicine, the Regenstrief Institute, Inc. and the Indiana University Center for Aging Research begin to answer this difficult question in a study...
