Tightly controlling the blood sugar levels of diabetics, even with the attendant risk of dangerously low levels of blood glucose, does not damage mental abilities, researchers have found. Patients did not suffer in tests of intelligence, memory, coordination, language and other mental abilities, they reported in the May 3 issue of the New England Journal of Medicine. "It certainly helps decrease a worry that I get asked about a lot," Dr.

Low levels of testosterone in the bloodstream could indicate that a man is at increased risk of developing Alzheimer's disease. Scientists have long thought that estrogen protects cognitive function in women and wanted to see if testosterone might have a similar effect in men, either reducing the incidence of Alzheimer's or delaying its onset.

Five medications have been approved to treat the cognitive symptoms of Alzheimer's disease. The drugs can reduce some symptoms — such as difficulties with memory, language, attention and reasoning — especially in the early stages of the disease. They can, accordingly, improve quality of life, but they don't work for everyone, and none of them works permanently. Eventually the disease will overtake the drugs' ability to compensate. Four of the medications are cholinesterase inhibitors.

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.

The numbers are staggering: Almost 7% of the U.S. adult population - about 17.6 million people - is diagnosed with depression, according to the National Institute of Mental Health. The national Centers for Disease Control and Prevention report that depression costs 200 million lost workdays each year at a cost to employers of $17 billion to $44 billion. There are effective treatments for depression, including, researchers said recently, meditation. But neither talk therapy nor the existing medications work for everyone.

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.

Winners of the Indianapolis 500 drink milk to celebrate their victory; perhaps winners of the Nobel Prizes do the same after receiving a congratulatory phone call from Stockholm. That's one theory to explain why countries in which people drink the most milk, per capita, also win the most Nobel Prizes , per capita, according to a new study . Take Sweden, the country that's home to the Nobels. Citizens there have won 31.855 prizes for every 10 million people. They also consume about 350 kilograms of milk each, on average, over the course of a year. At the other end of the spectrum is China, a country that has won a mere 0.060 Nobels per 10 million people and where the average person drinks less than 50 kilograms of milk per year. The United States fall close to the middle, with a Nobel-winning rate of 10.731 per 10 million citizens and milk consumption of abotu 250 kilograms per person per year. Coincidence?

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.

Lapsed musical instrumentalists (and their disappointed parents): Take heart! The child that gets even a few years of formal musical training before quitting those weekly lessons continues to show evidence that his or her brain has been changed in ways that improve mental function, says a new study. The latest research found that even years after they stopped practicing, young adults who had taken as little as two or three years of instrumental music training in their elementary or middle-school years showed a more robust brain response to sounds than those who had no formal musical training.

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.
