Cognitive Effects of Transcranial Direct Current Stimulation in Older Adults

Completed · Not applicable · Has a placebo group

Conditions studied: Aging

In brief

This research is being done to determine whether transcranial direct current stimulation (tDCS) can improve certain mental abilities. In this research, a 9 volt battery is used to deliver very weak electrical current to the surface of the scalp while participants complete cognitive tasks. Our aim is to find out whether tDCS will improve task performance in adults over the age of 55.
