http://medicalxpress.com/news/2016-03-in...itive.html -- "Using an MRI scan, the researchers measured the volume of the hippocampus—a brain region integral to memory function—in adults aged 65 years and older who were cognitively intact and dementia-free.
Diminished hippocampal volume is a well-known sign, or biomarker, of Alzheimer's disease and the eventual development of dementia.
The study, led by Lisa Silbert, M.D., with the OHSU Layton Center for Aging & Alzheimer's Disease, found that an additional hour of computer use a day was associated with a .025 percent larger hippocampal volume. A smaller hippocampal volume is an indicator of increased risk for developing Alzheimer's disease. The researchers will continue to follow these participants to see if their smaller hippocampal volume and decreased computer use predict future cognitive decline.
Silbert and colleagues hypothesize that the reason that patients with smaller hippocampal volumes may spend less time using their home computer is it requires the use of multiple cognitive domains, including executive function, attention and memory."
