Assessment of Cognitive Functions in Adults Aged 18 to 70 With Focal Brain Injuries from Stroke or Surgery

What this Trial Is About

This research focuses on studying cognitive difficulties linked to specific brain injuries and their locations. The aim is to build a large database of patient behavioral responses during cognitive tasks to better understand brain function. The study includes patients with focal brain lesions caused by stroke or surgical removal of brain tissue, which affect functions like attention, language, memory, decision-making, and executive function. Participants will undergo cognitive tasks that assess various higher brain functions such as attention, language, memory, decision-making, and executive skills. These tasks are observational and involve patients who have had focal brain injuries either from stroke or brain surgery. The study collects data during routine visits scheduled at 3, 6, 12, or 24 months after the brain lesion, with up to four sessions lasting about two hours each. During the study, participants will perform cognitive tasks while their behavioral performance, including reaction times and error rates, is recorded. These assessments happen during routine follow-up visits over two years. Researchers will analyze this data to explore links between brain structures and cognitive functions. The total participation may involve up to four sessions, each lasting approximately two hours, to track changes over time and better understand cognitive deficits after brain injury.
