Around the time of menopause, many women complain of mental slippage. But, as if to inflict some perverse trick upon them, cognitive scientists have found that they actually perform no more poorly than women who do not have such complaints. (Reassuring in a way: You're not losing your memory, but you may be losing your mind.) A new study finds that both the women who complain of memory problems and the cognitive scientists are right. These women haven't fallen behind -- not yet at least-- because their brains are working harder to keep up. The study, presented Sunday at the Society for Neuroscience's yearly confab -- held this year in Washington, D.C. -- recruited 22 healthy women with an average age of 57, all post-menopausal.

Middle-aged men who consume an average of more than 2½ alcoholic drinks per day accelerate the rate at which their memories decline by almost six years over a 10-year span, says a new study. And while a higher consumption of spirits such as vodka, gin, whiskey or scotch was linked to the fastest rates of mental decline in men, researchers saw little difference between the cognitive loss seen in heavy beer drinkers (who drank more than 2½ 12-ounce beers per day) and that seen in men who quaffed a half-bottle of wine or more per day. Compared with men who drank no more than 1½ drinks per day on average (up to 19.9 grams of alcohol daily)

With no cure in hand for Alzheimer's disease, many ask why someone would necessarily want an early diagnosis. But research continues to focus on detecting the earliest signs of dementia, and on the factors that give rise to some dementias or fuel their relentless progression. Those findings may point the way to prevention strategies. And they may allow physicians to recognize Alzheimer's disease and other dementias before they have taken a measurable toll. Stopping or slowing it there might be easier than reversing it, and could, for all practical purposes, be as good as a cure.

There's little argument that exercise is good for your body, but researchers have found that exercising to music may make you smarter too. An Ohio State University study found that verbal skills improved significantly in cardiac rehabilitation patients who exercised on a treadmill while listening to Vivaldi's "Four Seasons." "There have been a number of studies that have looked at the effects of just exercise or music on cognitive function," said Charles F.

Ginkgo trees, native to China, can live as long as 1,000 years. It may be this longevity that has convinced people over the ages that the leaves can give elderly people more vigor. As far back as ancient China, ginkgo biloba was considered to be good for the heart and lungs. Extracts made from the tree's leaves continue to be among the most popular herbal remedies in the world today.

Adolescent soccer players need better education about the symptoms of concussion and dangers of playing with head injuries, medical experts said Tuesday. In a new report, the Institute of Medicine, part of the National Academy of Sciences, said that studies of the effects of "heading"--hitting the ball with the head--have been inconclusive and that additional research is needed. But the risk of concussion in contact sports, including soccer is real, according to the report.

Walking promotes good physical health, but it may also help maintain memory and cognitive function for years, a study finds. The research, published online Wednesday in the journal Neurology , is based on a study of 299 men and women, average age 78, who were followed for nine years. The study participants were asked about their physical activity, which was calculated as number of blocks walked per week (walking was the most common exercise). Study subjects walked from zero to 300 blocks over a one-week period.

A biological medication already widely used to treat plaque psoriasis may be able to slow the accumulation of amyloid plaques in the brain that are the hallmark of Alzheimer's disease, a new study has found. The same study found that in older mice with established Alzheimer's, this treatment approach, which suppresses the brain's immune reaction to beta amyloid, brought a marked improvement in cognitive function and may even halt or reverse early signs of Alzheimer's. The new study was published this week in the journal Nature Medicine.

I'm 46, and there are days when it feels like I'm completely losing my mind. I misplace my car keys, struggle to remember details of recent conversations, and can't recall seemingly anybody's name. To help cope with my mental cloudiness, I always keep an extra set of keys nearby, write endless sticky notes to myself, and frequently opt for the generic "hello" over more personalized greetings. Strategies like these may help me get through my day, but they fail to calm the nagging concern that something is seriously wrong with me. They also do nothing to combat the other "symptoms" that have developed over the last year or two, namely trouble sleeping and a vague sense of doom and gloom.

Scientists have performed the first successful neural stem cell transplant into the brains of four boys with Pelizaeus-Merzbacher disease. The disorder is a rare but tragic condition that impacts motor abilities, coordination and cognitive function. Pelizaeus-Merzbacher disease does its damage by stripping away the fatty substance called myelin that surrounds brain cells. Myelin acts as an insulator, like rubber on the outside of a wire, helping the electrical impulses that carry information in the brain travel at high speeds.
