Dementia Begins at Age 27

Man's brain starts to decline in late 20s, studies say. Yeas, a new study on aging indicates that reasoning, speed of thought and spatial visualization begin to decline in that age, the BBC reports.
Professor Timothy Salthouse of Virginia University, who worked on the research, said: "Results converge on a conclusion that some aspects of age-related cognitive decline begin in healthy, educated adults when they are in their 20s and 30s."



In the study, the BBC says, Salthouse had his subjects solve puzzles, recall words and details of stories, and spot patterns in letters and symbols. In nine out of 12 tests, the BBC says, 22 was the average age for peak performance. Marked decline began at 27.

It means that just the findings could mean that therapies designed to slow or reverse the aging process may need to start much earlier.
