Stroke is the leading cause of long-term disability with an increasing incidence, especially in young adults. Among the cognitive difficulties following brain damage, deficits in attention are frequent and pervasive, affecting between 46% and 92% of stroke survivors. The current project targets patients with acquired brain injury, including stroke, traumatic brain injury, and brain tumor. The main objective of this study is to evaluate the use and the efficacy of a training program targeting attention and executive function difficulties, using gamified and digitized versions in virtual reality of standard cognitive exercises for patients with brain lesions.
