Efficacy of Web-Based Social-Cognitive Interventions in Right Hemisphere Stroke and Frontotemporal Dementia

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.

The study will be based out of the Johns Hopkins Hospital where patients will be assessed
three times in total. Patients will be assessed upon enrollment in the study and after each
of the two treatment conditions. The training itself will be completed at home on a provided
laptop, with monitoring and support by the study team. This study uses a crossover design,
which means that all patients will receive the training treatment and a control treatment
during their participation in the study. The approximate timeline for the study is 9 weeks
total.
