Attention deficits of patients with chronic-stage traumatic brain injury: a behavioral study involving a dual...

We quantitatively evaluated memory performance in patients in the chronic stage of closed traumatic brain injury using dual visual tasks. Simple memory tests and questionnaires concerning activities of daily living (ADL) were also utilized to evaluate any correlation with the results of the dual tasks. The results of dual tasks and memory tests were correlated with the daily activity scores, but there was no correlation between the results of dual tasks and memory tests. We concluded that the dual task was effective for detecting memory and ADL disturbances, which were not disclosed by conventional memory tests.
