Neuropsychological and neuroradiologic correlates of emotional prosody comprehension

Abstract

We examined a series of 59 patients with acute stroke lesions for the presence of comprehension emotional aprosody. Based on a standardized assessment of comprehension of emotional intonation, 29 patients (49%) showed emotional aprosody (17% “mild” aprosody [n = 10] and 32% “severe” aprosody [n = 19]). Patients with comprehension emotional aprosody showed a higher frequency of extinction on double-simultaneous stimulation, anosognosia, and deficits in facial emotion comprehension. Patients with comprehension emotional aprosody also showed a higher frequency of right-hemisphere lesions involving the basal ganglia and the temporoparietal cortex and more severe frontal and diencephalic atrophy. Comprehension emotional aprosody was not necessarily associated with poststroke depression (PSD) since patients with and without PSD showed similar impairments in emotional prosody comprehension.
