Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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. 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. The study aims to understand how our computer program can affect cognition and attention in those with acquired brain injury.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Following consent, participants will engage in an assessment process to determine eligibility. Once eligibility is confirmed, participants will be scheduled for another assessment session 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 an Internet browser-delivered training sessions conducted on any internet-accessible computer. The computerized training sessions can be done up to 7 times a week (once a day) or at participant's convenience (we recommend 5 times a week). Following the completion of training, the participant's cognitive function will be re-assessed and again after 3-month no-contact period. Participation is voluntary and participants may withdraw from the study at any time.
