Emotional sequelae of stroke: a longitudinal perspective.

This study investigated emotional change following stroke at acute (2-week), 2-month, and 6-month time intervals. Five dimensions of emotional functioning were examined in a sample of 19 stroke subjects: indifference, inappropriateness, depression, mania, and pragnosia (a defect in the pragmatics of social communicative style). Results showed that, at the 2-month point, differential recovery rates become apparent depending on hemispheric side of the stroke lesion. Increased indifference, inappropriateness, and depression appear to account for these results and suggest a slower rate of recovery on these variables in the left hemisphere group (LH n = 9) compared to the right (RH n = 10). Results further indicate that, at the 6-month point, emotional functioning in RH subjects appears to worsen. In contrast, emotional recovery in LH subjects seems to stabilize at this time. Clinical implications of these findings in terms of type and timing of intervention are discussed.
