Introduction:
Deficits of emotion recognition after ischemic stroke are often overlooked by clinicians, and are mostly not spontaneously reported by patients. However, impaired emotion recognition after stroke negatively affects the ability to return to work and the quality of life. It is still unknown how often impairments of emotion recognition occur shortly after ischemic stroke. We aimed to estimate the occurrence of impaired emotion recognition after ischemic stroke and to characterise these patients with impaired emotion recognition.
Patients And Methods:
Two hundred thirty patients were included, derived from a prospective study of cognitive recovery. Five weeks after ischemic stroke a neuropsychological assessment was performed, including an emotion recognition task (i.e. Ekman 60-faces test). Emotion recognition was regarded as impaired if the total score was below the fifth percentile for a large independent reference sample.
Results:
Emotion recognition was impaired in 33.5% of patients. Patients with impaired emotion recognition were more likely to have an abnormal Montreal Cognitive Assessment during hospitalisation, and 5 weeks after their stroke, a higher proportion of them had a vascular cognitive disorder (VCD). Even 20% of patients without VCD had impaired emotion recognition.Discussion: Emotion recognition was often impaired after ischemic stroke. This is clinically relevant, since impaired emotion recognition negatively impacts social functioning.Conclusion: Even when there was no cognitive disorder in traditional cognitive domains, emotion recognition was impaired in 1 out of 5 patients. Clinicians should systematically ask patients and their caregivers about deficits in emotion recognition, and, if needed, test for these deficits.
