tDCS: All participants randomized to tDCS will receive active tDCS
Exercise: Participants will exercise at Toronto Rehab.
Sham stimulation: The same procedure for tDCS will be used for the sham condition, except without active current.
Treatment as usual: Exercise education/ treatment as usual will include routine advice about physical activity.
Study summary
People with vascular conditions are at risk of having memory problems, and these memory problems increase the risk for further cognitive decline. Brain stimulation has been used to improve mood and memory. Transcranial direct current stimulation (tDCS) is believed to work best on brain cells that are active or "primed" before stimulation. The purpose of this study is to compare the effects of exercise and tDCS on memory performance in patients who have completed cardiac rehabilitation and are at risk of cognitive decline.
