: We describe a patient who was ill for more than 15 years. She was treated predominantly as a neurological case because of multiple motor signs. The diagnosis of catatonia was considered at the time when she was hospitalized in a psychiatric hospital after a suicidal attempt. The "therapeutic blindness", which was obviously present during 15 years of her illness, is discussed: the ICD--10 is perhaps misleading regarding this diagnosis while it associates it too tightly only to schizophrenia.
