The perception of emotional facial expressions in stroke patients with and without depression
Published online by Cambridge University Press: 24 June 2014
Emotion perception may be impaired after stroke. No study on emotion perception after stroke has taken the influence of post-stroke depressive symptoms into account, although depressive symptoms themselves may hamper emotion perception.
To compare the perception of emotional facial expressions in stroke patients with and without depressive symptoms.
Twenty-two stroke patients participated whose depressive symptoms were classified using the Montgomery-Åsberg Depression Rating Scale (cutoff = 10) and who were compared with healthy controls. Emotion recognition was measured using morphed images of facial expressions.
Patients with depressive symptoms performed worse than controls on all emotions; patients without depressive symptoms performed at control level. Patients with depressive symptoms were less sensitive to the emotions anger, happiness and sadness compared with patients without depressive symptoms.
Post-stroke depressive symptoms impair emotion perception. This extends findings in bipolar disorder indicating that emotion perception deficits are strongly related to the level of depression.
