Auditory attention in early Parkinson's disease: an impairment in focused attention.
Focused attention in the auditory modality was studied in a group of Parkinson patients and compared to matched controls using a Dichotic monitoring task. Parkinson patients detected more phonemic distractors on the unattended input than the normal controls, despite a high level of ipsilateral responses for target detection and target discrimination. This impairment in focused attention may be attributed to degenerative changes in the ascending monoamine pathways which have been implicated in the role of auditory attention.
