About this trial
As individuals grow older, a number of factors can reduce our cognitive (or thinking) abilities such as "normal" aging, neurodegenerative diseases, and cardiovascular disease. This study will evaluate whether cognitive rehabilitation and transcranial electrical stimulation (TES) can improve cognitive abilities. Cognitive rehabilitation refers to methods that are used to improve tasks people have trouble doing in everyday life. Transcranial electrical stimulation uses small amounts of electricity to try to alter brain functioning. These approaches may help improve cognitive abilities like attention, learning, memory, finding words, and problem solving as well as everyday functioning. The goal of this study is to identify how to best use these methods, either alone or in combination.
