Less frequent computer use ‘could predict early cognitive decline’

People who use their computers less often may be more likely to experience early cognitive decline as they age, according to a new study.

Researchers from Oregon Health and Science University used MRI scans to measure 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 at the outset.

It was found that an additional hour of computer use a day was associated with a .025 percent larger hippocampal volume, indicating these people have a lesser risk for developing Alzheimer's disease.

The scientists have hypothesised patients with smaller hippocampal volumes may spend less time on the computer because it requires the use of multiple cognitive domains, including executive function, attention and memory.

These participants will continue to be followed to see if this smaller hippocampal volume and decreased computer use can accurately predict future cognitive decline. Generally, diminished hippocampal volume is seen as a key warning sign of the eventual development of dementia.
