R1. Relationship Between Attention and Discourse in Patients with Right Hemisphere Damage: A Treatment Efficacy Study
Patients with right hemisphere damage following stroke (RHD) typically demonstrate a variety of cognitive deficits that impact on the effectiveness and efficiency of their communication skills. One of the most salient characteristics of RHD is the presence of unilateral neglect, a complex disorder in which patients ignore, or do not respond to stimuli on the contralateral side to the lesion, although they have the motor and sensory capacity to do so. Several studies have targeted intervention techniques for unilateral neglect. While training effects were evident, they were restricted to measures that shared stimulus characteristics with the training materials and did not generalize to tasks that are more functional. Conversely, functional tasks that have been used clinically have not been systematically evaluated for their efficacy. The purpose of this study is: 1) to develop two rehabilitation techniques for patients with persistent unilateral neglect; and 2) to evaluate and compare the effects of these interventions on the patient's communication skills and subsequently on his/her quality of life. In addition, the study evaluates the relationships between attention, unilateral neglect, and discourse in patients with acute RHD.
