Abstract
Although there is increasing evidence that cerebellar loss of grey matter volume GMV is associated with affective deficits this has not been tested for patients suffering from Huntington’s disease HD who show a pronounced impairment in the recognition of anger We assessed GMV in 18 symptomatic HD patients and 18 healthy controls using voxelbased morphometry The GMV of cerebellar subregions was correlated with participants’ intensity and accuracy ratings for facial expressions of basic emotions from the Karolinska Directed Emotional Faces Lundqvist et al 1998 The patients gave lower and less accurate anger ratings for angry faces than controls This anger recognition deficit was correlated with atrophy of selected hemispheric and vermal regions of the cerebellum Furthermore cerebellar volume reductions of the HD patients were associated with longer disease duration and greater functional impairment The data imply that anger recognition deficits could potentially serve as indicators of disease onset and progression in HD Furthermore the patients might profit from specific affect trainings
