Autopsy study of mild cognitive impairment

A study led by Mayo Clinic demonstrates that mild cognitive impairment, a memory disorder considered a strong early predictor of Alzheimer's disease, not only results in behavioral symptoms, but also structural changes that can be identified in the brain. Findings will be published in the May issue of Archives of Neurology.

Brain scan could reveal who will get Alzheimer's disease

According to researchers in California, a brain scan may possibly identify structural and metabolic brain changes that predict dementia or cognitive decline in normal older adults.

New study describes molecular basis of NeuroAIDS

Using multi-disciplinary analysis that included cognitive, neurophysiologic, virologic, and molecular techniques, the team found both a low-level viral infection in the brain and immune cells that had infiltrated the brain in order to protect against the virus.

Amyloid protein content in the brain linked to Alzheimer's disease risk

Researchers from the Flanders Interuniversity Institute for Biotechnology (VIB) connected to the University of Antwerp are the first to show that the quantity of amyloid protein in brain cells is a major risk factor for Alzheimer's disease. Amyloid protein has already been known to be the primary component of the senile plaques in the brains of patients. The new discovery demonstrates that the greater the quantity of the protein that is produced, the younger the dementia patient is.

Friends and family can protect against Alzheimer's disease

Having close friends and staying in contact with family members offers a protective effect against the damaging effects of Alzheimer's disease according to research by physicians at Rush University Medical Center in Chicago. The study, which is currently posted online in The Lancet Neurology, will be published in the May print edition of the journal.

Promising treatment for Huntington's disease soon to be tested clinically

At the Institut Curie, CNRS and Inserm researchers have shown that cysteamine, which is already used to treat a rare disease called cystinosis, prevents the death of neurons in Huntington's disease. Like Alzheimer's and Parkinson's, Huntington's disease, is characterized by the abnormal death of neurons.

Mediterranean diet reduces risk of Alzheimer's disease

Americans who ate a Mediterranean diet--lots of fruits, vegetables, legumes, cereals, some fish and alcohol, and little dairy and meat--had a reduced risk for Alzheimer's disease as they aged. These findings are published in the April issue of Annals of Neurology.

Anxiogenic-like effect of chronic corticosterone in the light-dark emergence task in mice

Neuroscientists at Harvard Medical School and its affiliate McLean Hospital have shown that long-term exposure to stress hormone in mice directly results in the anxiety that often comes with depression.

Cystamine and cysteamine increase brain levels of BDNF in Huntington disease via HSJ1b and transglutaminase

Huntington disease (HD) is a degenerative brain disease in which brain cells called neurons die as a result of aggregations of the polyQ-huntingtin protein.

Maintaining high blood pressure treatment may reduce the risk of dementia in old age

Lead author of the study Rita Peila, Ph.D., an epidemiologist at the National Institute on Aging (NIA), said "For every year of hypertension treatment, there is increased protection against dementia."

A drink or two a day may be associated with better cognitive function in women

"Women who had up to two drinks a day scored about 20 percent higher on the Mini Mental State Exam (MMSE) than women who didn't drink at all or who consumed less than one drink a week," said Clinton Wright, M.D., M.S., lead author of the study.

Removal of a woman's ovaries raises risk of dementia

Mayo Clinic researchers have found that ovariectomy, surgical removal of a woman's ovaries, raises her risk of developing dementia or cognitive impairment. Risk is especially increased if a woman has her ovaries removed at a young age.
