Abstract: ObjectiveTo evaluate the attentional ability following brain injury.Methods26 patients with brain injury including traumatic brain injury(TBI) and stroke, and 30 normal volunteers were randomly selected. Different attention tests(Continuous Performance Test, Stroop Color-Word Interference Test, Trail Making Test and Paced Auditory Serial Addition Task) were applied to assess the attentional ability of the patients and normal volunteesrs. Then the data were sorted out before statistical analysis was performed.ResultsThere was significant difference between the normal and brain injury groups in scores(P＜0.05). There was no significant difference between TBI and stroke in scores(P＞0.05).ConclusionThe multiple aspects of attention deficit existed in the patients with brain injury, including sustained attention, selective attention, divided attention and attentional switching. Clinical manifestations of attention deficit after traumatic brain injury and stroke is closely related with the injury site.
