| Abstract: |
Neuropsychological deficits are a main feature of Huntington's disease(HD) with previous data suggesting involvement of attentional functions. Attentioncan be divided into several different dimensions: intensity, selectivity andsupervisory attentional control. These different aspects of attention wereinvestigated in a group of 13 patients with HD and 13 healthy matched controlsubjects. HD patients were impaired mostly for the intensity dimension: contraryto controls, and like other neurological patient groups, they were not ableto speed up their reaction times when an auditory warning stimulus precededa visual target which suggests a deficit in ‘extrinsic alertness.’In addition less severe impairments were found in the dimensions selectivityand supervisory attentional control.
