Overview of forensic outpatients on the Medical Treatment and Supervision Act in Japan
In Japan, the Medical Treatment and Supervision Act (MTSA) has been in effect since 2005, and a support system has been established for those found not guilty by reason of insanity (NGRIs). Under this law, the reintegration of the subjects into society is underway. This paper summarizes the status of forensic outpatients during the seven years after its enactment. Information on forensic outpatients was obtained from 224 designated outpatient med…
Clinical Characteristics of Missed Child-to-Parent Violence (CPV) in Child and Adolescent Psychiatric Patients
This study investigated the clinical characteristics of missed child-to-parent violence (CPV) in child and adolescent psychiatric patients via a retrospective case-control design. Data were obtained from 177 patients aged under 15 years during their initial consultation at the National Kohnodai Medical Center, Japan, between April 2022 and March 2023. We obtained CPV cases identified via the Child-to-Parent Violence Questionnaire Parents' Version…
Violent Behavior Prior to Admission Is Not a Factor in Further Prolonged Length of Stay
Background: This study assessed the hypothesis that violent behavior prior to admission prolongs psychiatric hospitalization and evaluated the likelihood of hospital discharge to a community care setting based on demographic and clinical factors, with an emphasis on violent behavior. Methods: We retrospectively selected 362 patients who were involuntarily admitted to a psychiatric hospital in Japan from December 1, 2015 to November 30, 2017, stay…
Treatment Response Distinguishes Persistent Type of Methamphetamine Psychosis From Schizophrenia Spectrum Disorder Among Inmates at Japanese Medical Prison
Introduction: Persistent methamphetamine-associated psychosis (pMAP) is a disorder similar to schizophrenia, so much so that the differences in clinical symptoms and treatment response between the two remain unknown. In this study, we compared the features of pMAP with those of schizophrenia spectrum disorders (SSD). Materials and Methods: This was a retrospective quasi-experimental case-control study of inmates in a medical prison. The behaviora…
Risk Factors for Problematic Behaviors among Forensic Outpatients under the Medical Treatment and Supervision Act in Japan
The Medical Treatment and Supervision Act (MTSA) was enacted in 2005 in Japan to promote the reintegration of clinical offenders with mental disorders into society. Under the MTSA, individuals who committed serious crimes in a state of insanity or diminished responsibility are diverted from the criminal justice system to the mental health system. Based on court decisions about MTSA-based treatment, clinical offenders have an obligation to engage …
Impulsivity is Associated with Early Sensory Inhibition in Neurophysiological Processing of Affective Sounds
Impulsivity is widely related to socially problematic behaviors and psychiatric illness. Previous studies have investigated the relationship between response inhibition and impulsivity. However, no study has intensively examined how impulsivity correlates with automatic sensory processing before the drive for response inhibition to sensory inputs. Sensory gating (SG) is an automatic inhibitory function that attenuates the neural response to redun…
