Computerized Attention Training for Individuals With Acquired Brain Injury

Computerized Cognitive Treatment of Vigilance Deficits in Individuals With Acquired Brain Injury

Problems with attention are a common and debilitating consequence of brain injury. Studies show that poor attention is the number one predictor of poor cognitive functioning one year post-injury. This is due to the fact that attention is a necessary component of more complex cognitive functions such as learning & memory, multi-tasking and problem solving. In many cases, individuals may exhibit problems with spatial attention known as 'hemi-spatial neglect syndrome' or simply 'neglect'. Many studies now show that the processing machinery of the brain is plastic and remodeled throughout life by learning and experience, enabling the strengthening of cognitive skills or abilities. The investigators own research has shown that brief, daily computerized cognitive training that is sufficiently challenging, goal-directed and adaptive enables intact brain structures to restore balance in attention and compensate for disruptions in cognitive functioning.

Participants will first engage in an assessment process to determine current level of cognitive function. This process consists of paper-pencil surveys and computerized tests. Following the assessment process, participants will engage in Internet browser-delivered training sessions conducted on any internet-accessible computer. These trainings can be done up to 7 times a week (once a day) or at participant's convenience (the investigators recommend 4-5 times a week). Following the completion of training, participant's cognitive function will be re-assessed. Participation is voluntary and participants may withdraw from the study at any time.
