Aita C, Mizoguchi Y, Yamamoto M, SeguchI Y, Yatsuga C, Nishimura T, Sugimoto Y, Takahashi D, Nishihara R, Ueno T, Nakayama M, Kuroki T, Nabeta H, Imamura Y, Monji A., Oxytocin levels and sex differences in autism spectrum disorder with severe intellectual disabilities., Psychiatry Research, 10.1016/j.psychres.2018.12.139, 273, 67-74, 2018.12, There were few reports of oxytocin (OXT) concentrations of autism spectrum disorder (ASD) patients with severe intellectual disabilities. We measured serum OXT concentrations in 79 hospitalized patients with severe intellectual disabilities (16-60 years old, 50 males and 29 females, 54 ASD patients) and investigated the associations between serum OXT concentration, symptom scores, sex differences, and autism spectrum disorder. There were no significant effects of diagnosis, severity of intellectual disabilities, and total score of the Japanese version of the Aberrant Behavior Checklist (ABC-J), the Childhood Autism Rating Scale-Tokyo Version (CARS-TV), and the Japanese version of the Repetitive Behavior Scale-Revised (RBS-R). However, there were sex differences in the correlations between OXT concentrations and subscale scores in the ASD group. The male ASD group (n = 39) showed negative correlations between RBS-R Self-injurious and Sameness subscale scores and serum OXT concentrations. In the female ASD group(n = 15), CARS-TV Nonverbal communication subscale scores and RBS-R Compulsive subscale scores were seen to positively correlate with serum OXT concentrations. These findings suggest that OXT functions differ in males and females with severe intellectual disabilities and that OXT partly affects autism and related to some of the repetitive behaviors and nonverbal communication, in ASD patients with severe intellectual disabilities..

1. 黒木 俊秀, Outcome research on traditional Morita Therapy and the notation of therapeutic recovery in Morita Therapy., The 9th International Congress of Morita Therapy, 2016.09, The efficacy of traditional Morita therapy has been discussed by Dr. Morita and his followers using a number of clinical case studies and case illustrations. Researchers have also used follow-up outcome survey data for both descriptive and non-inferential statistics for analysis. The researchers who have reported these studies are practitioners of Morita therapy themselves, and according to them, over 80% of residential clients became able to resume a normal and active life after the treatment. It should be noted that successful treatment of shinkeishitsu clients using traditional Morita therapy does not require the elimination or minimization of anxiety symptoms and other ego-threatening feelings and traits. Recovered clients may still experience anxiety from time to time, but they do not stay preoccupied with resisting anxiety and uncomfortable feelings any longer. One traditional Morita therapist has said: “A cure is achieved by a non-cure.” This notion of therapeutic recovery in traditional Morita therapy may not be compatible with the modern outcome research methodology for evaluating therapeutic effects of psychotherapy..
