Although deficits in empathy and social interaction are relatively common in certain forms of FTD and stroke, there are currently no proven treatments for these symptoms. Spouses and caregivers often cite these symptoms as a major concern, and these deficits can have a negative impact on the quality of life that patients experience. The purpose of this study is to evaluate whether or not web-based social training exercises can improve social-cognitive impairments in patients with FTD or right hemisphere stroke. These training exercises have been shown to improve social skills and empathy in other disorders. This study will be the first to examine if these exercises can be effective and feasible for treating social deficits in stroke and FTD.
