Relative absence of psychopathology in benign essential blepharospasm and hemifacial spasm.

We report on the psychopathology and illness-related changes of life in patients with benign essential blepharospasm (BEB) or hemifacial spasm (HFS). Fifty-six patients with BEB and 40 patients with HFS completed the SCL 90R, a screening instrument for psychiatric symptomatology, and the Freiburg Questionnaire for Dystonia (FQD), a questionnaire about psychosocial changes in subjects with movement disorders. In both BEB and HFS patients, the mean scores on all but one subscale of the SCL 90R remained within the double standard deviation of normal. In comparing BEB to HFS patients in illness-related changes of life, BEB patients were more severely disabled in all areas of life examined. Psychological distress in BEB, but not in HFS, correlated with physical disability and in particular with impairment of vision.
