Alzheimer’s disease (AD) is the most common form of dementia, a neurologic disease characterized by loss of mental ability severe enough to interfere with normal activities of daily living, lasting at least six months, and not present from birth. AD usually occurs in old age, and is marked by a decline in cognitive functions such as remembering, reasoning, and planning.
People who reliably took the ginkgo biloba supplement had a 68 percent lower risk of developing mild memory problems. – Taking the supplement ginkgo biloba had no clear-cut benefit on the risk of developing memory problems, according to a study published in the February 27, 2008, online issue of Neurology, the medical journal of the American Academy of Neurology.
Rates of cognitive impairment among older Americans are on the decline, according to a new study supported by the National Institutes of Health (NIH) comparing the cognitive health of older people in 1993 and 2002. Higher levels of education were associated with better cognitive health. – Higher levels of health education improved cognitive health among older Americans. Rates of cognitive impairment among older Americans are on the decline, according to a new study supported by the National Institutes of Health (NIH) comparing the cognitive health of older people in 1993 and 2002.
Good news on gray matter: Memory loss and other cognitive impairment becoming less common in older Americans, U-M study finds; Better education, finances & cardiovascular care may be boosting brain health. – It appears that memory loss and thinking problems are becoming less common among older Americans. A new study shows a downward trend in the rate of “cognitive impairment” – the umbrella term for everything from significant memory loss to dementia and Alzheimer’s disease – among people aged 70 and older.
Changes in folate, vitamin B12 and homocysteine associated with incident dementia. – Folate deficiency is associated with a tripling in the risk of developing dementia among elderly people, suggests research published ahead of print in the Journal of Neurology Neurosurgery and Psychiatry.
UCI study identifies the specific role for gene linked to cortical development, cerebral cortex points to potential stem cell treatments. – University of California, Irvine researchers have identified a gene that is specifically responsible for generating the cerebral cortex, a finding that could lead to stem cell therapies to treat brain injuries and diseases such as stroke and Alzheimer’s.
A large US study suggests that statin, cholesterol lowering drug use does not lower the risk of Alzheimer’s disease (AD). – Taking statins, which are cholesterol-lowering drugs, offers no protection against Alzheimer’s disease, revealed by US researchers at Rush University Medical Center in Chicago.
UF scientists are testing the safety of experimental drug Compstatin for vision loss in macular degeneration patients. – University of Florida UF scientists are testing the safety of experimental drug Compstatin for vision loss in macular degeneration patients. In a first-of-its-kind safety research study, University of Florida researchers have injected an anti-inflammatory compound into the eye of a person with a sight-robbing disease.
New Tel Aviv University (TAU) research links depression to loss of the sense of smell, suggesting that the blues may have biological roots. – Can’t smell the roses? Maybe you’re depressed. Smell too much like a rose yourself? Maybe you’ve got the same problem. Scientists from Tel Aviv University recently linked depression to a biological mechanism that affects the olfactory glands. It might explain why some women, without realizing it, wear too much perfume.
Scientists have for the first time identified brain sites that fire up more when people make impulsive decisions. In a study comparing brain activity of sober alcoholics and non-addicted people making financial decisions, the group of sober alcoholics showed significantly more “impulsive” neural activity. – Alcoholics are more impulsive than non-addicted people making financial decisions, revealed by researcher Charlotte Boettiger at the University of North Carolina at Chapel Hill.
There may be a difference in response to treatment in Alzheimer’s Disease (AD) patients with and without white matter disease in selective areas of the brain.
– Researchers at Sunnybrook have shown that there may be a difference in response to treatment in Alzheimer’s Disease (AD) patients with and without white matter disease in selective areas of the brain.
