The author reviewed 55 patients who had been treated as anorexia nervosa at the neuropsychiatric department of Okayama University Medical School and at the internal medicine department of Misasa Branch Hospital, Okayama University Medical School, for the past ten years from 1970 to 1980. The criteria for the present study was as
follows; 1) absence of psychosis and no known physical
illness for ematiation, 2) weight loss of at least 2096 of original body weight, 3) duration of anorexia of at least three months. 55 patients were classified into three groups
according to the age of onset ; pre-puberty group. adolescent group and adult group. Analysis of two female adolescent cases was described in this report for the preliminary study. The results were as follows : 1) Onset of self-starvation coincided with competitious hyperactivity in sport and/or study. Self-starvation seemed to have psychological meaning of retaliation towards the mother of each patient, of compensatory gain in the dependancy need. and of keeping a pride in pubertal competitions including a pursuit in the slim body image. 2) There was the evidence of a disturbed female-identification which originated from the disturbed mother-child interaction. 3) Catharsis with analytically oriented psychotherapy improved gastro-intestinal disorders such as anorexia and constipation and reversed the negative BMR (basal metabolic rate) to the positive BMR. Recovery of menstrual periods was followed in an accordance with re-gain of the original body weight.
