Two-thirds of patients sick enough to land in a hospital intensive care unit come away from the experience with substantial mental deficits, a new study has found. The new research, which quantifies a phenomenon long observed by critical-care physicians, found that three months after leaving the hospital, 4 in 10 patients continue to have cognitive problems on a par with those seen in cases of moderate traumatic brain injury. And more than a quarter experience a decline in mental function akin to that seen in patients with mild Alzheimer's disease, the study says.

If you have one of those kids who always has a nose buried in a book, here's a reason to be happy: Scientists say activities at any age that stimulate the brain may help preserve brain power into old age. The scientists assessed 294 people from the Chicago area who were ages 55 and older, using annual tests to measure thinking and memory and questionnaires about past reading, writing and other mentally stimulating activities. At death, which occurred at an average age of just over 89, they looked at their brains for signs of dementia.

Today, the term "fitness" is as likely to encompass the body as it is the mind. More than simply memory, "brain fitness" refers to a diverse suite of cognitive functions, including attention, working memory, perception, decision-making and emotional regulation, says Dr. Adam Gazzaley, a neuroscientist at UC San Francisco. "The field of brain fitness is built on the underlying concept of brain plasticity - the idea that the brain can modify or shape itself," he says.

An omega-3 fatty acid plentiful in fish oil boosts the ability of healthy young adults, whose brains are already at their peak levels of speed and performance, to hold several items in memory for a short time, a study has found. The study is the first to suggest that fish oil might enhance cognitive performance in healthy people by boosting their working memory. The latest research adds to evidence of fish oil's beneficial neuropsychiatric effects: Supplementation with the docosahexaenoic acid (DHA)

The Mediterranean diet has been linked to a host of health benefits, including a lower risk of heart disease , cancer and diabetes . A study finds that the diet may also be associated with a decreased chance of small vessel damage in the brain. The diet , popular in Mediterranean countries, includes little red meat but lots of fresh vegetables and fruit, lean proteins, whole grains and healthy monosaturated fats from olive oil and nuts. In the study, released Monday in the Archives of Neurology , researchers analyzed diet information on 966 people, average age 72, who answered a food questionnaire to see how close they came to consuming a Mediterranean diet.
