Scavenger cells could be key to treating HIV-related dementia
Understanding macrophages could lead to ways to prevent HIV-associated dementia Macrophages, long-living white blood cells often considered the scavengers of the immune system, actually may damage a part...Fruit fly reveals a potential connection between dementia and cancer
By expressing a protein associated with Alzheimer's disease in the brain of the fruit fly, researchers have demonstrated an intriguing link between neuronal death and proteins previously associated with cancer. Neurons in the brai...Hopkins study suggests commercially available antibiotic may help fight dementia in HIV patients
An antibiotic commonly used to treat a variety of serious infections may also help prevent dementia in HIV patients, according to a test-tube study of human brain cells by Johns Hopkins University School of Medicine neurologist Jeffrey Rumbaugh, M.D., Ph.D. Results of the lab study with ceftriaxone are expected to be presented at the American Academy of Neurology's 58th annual meeting on A...In-home sensors spot dementia signs in elderly
An Oregon Health & Science University study shows motion and door sensors placed in elders' homes can help track activity patterns thought to relate to memory changes that are early signs of dementia. The study results, presented last week at the 10th International Conference on Alzheimer's Disease and Related Disorders in Madrid, show that continuous, unobtrusive monitoring of in-hom...Viral genetic differences are possible key to HIV dementia
The study of 18 HIV-positive subjects shows that HIV in the brain and central nervous system is genetically different from HIV that lives in the blood and peripheral tissues. The study appears in the July 2006 issue of Brain. It was...Moderate alcohol consumption protects against dementia
Daily moderate consumption of alcohol, which has already been shown to help prevent heart disease and strokes, may also ward off Alzheimer's disease and other types of dementia.// The study also found that it doesn't seem to matter what people drink - the effect is the same. Researchers say moderate alcohol consumption between one and three drinks a day may protect against dementia. Th...Alcohol decreases risk of dementia
According to a new study carried out by researchers at Erasmus University in the Arizona moderate consumption of alcohol provides some protection// against dementia. We already know that moderate alcohol consumption - one to three drinks a day - reduces cardiovascular risk. Since blood vessel disease also affects the brain, might alcohol also protect against dementia. According to this...
