Preventing or Better Managing Diabetes May Prevent Cognitive Decline

ScienceDaily (June 21, 2012)

Preventing diabetes or delaying its onset has been thought to stave off cognitive decline — a connection strongly supported by the results of a 9-year study led by researchers at the University of California, San Francisco (UCSF) and the San Francisco VA Medical Center.

Earlier studies have looked at cognitive decline in people who already had diabetes. The new study is the first to demonstrate that the greater risk of cognitive decline is also present among people who develop diabetes later in life. It is also the first study to link the risk of cognitive decline to the severity of diabetes.

The result is the latest finding to emerge from the Health, Aging, and Body Composition (Health ABC) Study, which enrolled 3,069 adults over 70 at two community clinics in Memphis, TN and Pittsburgh, PA beginning in 1997. All the patients provided periodic blood samples and took regular cognitive tests over time. Read more
