More study needed on electronics, Alzheimer's

Posted August 10, 2015 1:00 am

In a July 21, 2015 article addressing the potential risks associated with Alzheimer's disease and related cognitive impairment from watching too much television, the author stated that children and young adults, who are more than ever glued to the screens of electronic gadgets, are also at risk for future cognitive decline and its devastating consequences.

I submit that watching TV is predominantly a passive activity, whereas computer engagement is a very active cognitive process requiring alertness, quick thinking, and a host of mental and fine motor gymnastics.

It is therefore logical to hypothesize that computer viewing and accompanying activity has a differential and relatively more positive effect on cerebral functioning than simple TV watching.

A definitive study comparing the effects of computer engagement and television viewing on brain development and decline would provide some clarity.
