Narcolepsy is characterized by excessive diurnal drowsiness with irresistible sleep attacks and cataplexy. Theobjective of this study was to assess, using the Rorschach test, affective characteristics of a sample of 16narcoleptics patients compared to 20 non-narcoleptics subjects. Based on a literature review, three hypotheseswere tested: narcoleptics, in comparison with non-narcoleptics, should demonstrate: 1) lower engagement inaffective situations; 2) greater affective constriction; 3) greater control in affective expression. Hypothesis 1and 2 were supported, but not hypothesis 3 because narcoleptics had shown lower control of affective reactionsthan non-narcoleptics. The results demonstrate the impact of the disease in the life of narcoleptics and indicatethe relevance of psychosocial care in treatment.
