The exergamers had better executive function when the study ended, and fewer progressed to mild cognitive impairment, often a precursor to dementia. They also had higher levels of a brain growth factor in their blood, possibly a sign that the exercise was stimulating changes in the brain.
Cay Anderson-Hanley, a Union College neuropsychologist who led the study, said cybercyclists did not exercise harder than the others, so the cognitive improvements likely were related to the experience of making decisions in a virtual environment while exercising.

Free pamphlet on drug-abuse treatment choices is available
The National Institute on Drug Abuse has a new, free pamphlet for families struggling to choose a drug-treatment program.
The eight-page booklet, "Seeking Drug Abuse Treatment: Know What to Ask," describes the principles of care and how to evaluate a program.
The brochure recommends asking about the scientific basis for the program, how it is tailored to individual patients' needs, the usual duration of treatment, and how 12-step programs fit in.
The booklet also describes available medications and behavioral therapies, the reality of relapse, and the role of community-level support.
A copy can be ordered by calling 1-877-643-2644 or downloaded from www.drugabuse.gov/publications/seeking-drug-abuse-treatment. - Marie McCullough
