Number of long-term inpatients in Japanese psychiatric care beds: trend analysis from the patient survey and the 630 survey.

Background: The number of psychiatric care beds and the mean length of stay in psychiatric care beds in Japan have decreased over the past 10 years. However, as has long been indicated here and elsewhere, Japan lags behind other countries in terms of deinstitutionalization. Furthermore, the population of inpatients in psychiatric care beds is aging dramatically.

Next-generation sequencing analysis of multiplex families with atypical psychosis.

Atypical psychosis (similar to acute and transient psychotic disorder, brief psychotic disorder) is highly heritable, but the causal genes remain unidentified. We conducted whole-genome sequencing on multiplex Japanese families with atypical psychosis. The patient group of interest shows acute psychotic features including hallucinations, delusions, and catatonic symptoms while they often show good prognosis after the onset.

Comparative Analysis of the WISC between Two ADHD Subgroups.

Objective: The prevalence of attention deficit/hyperactivity disorder (ADHD) in school-age children is 7.2%, and ADHD is divided into clinical subtypes.

Methods: The current study explored whether specific cognitive profiles as assessed using the Wechsler Intelligence Scale for Children (WISC)-IV could be obtained for each clinical ADHD subtype (ADHD-Inattentive type and ADHD-Combined type) and investigated the correlation between WISC scores and parental age at their children's birth or birthweight.

[The Unitary Psychosis Theory].

Since E. Kraepelin isolated schizophrenia and bipolar disorder as heterogeneous diseases, attempts to categorize mental illnesses have continued to the DSM-5. Meanwhile, cases of psychosis occurring as a result of neurosyphilis have been reported.

Correlation between frontal lobe oxy-hemoglobin and severity of depression assessed using near-infrared spectroscopy.

Introduction: The search for objective biomarkers of psychiatric disorders has a long history. Despite this, no universally accepted instruments or methods to detect biomarkers have been developed. One potential exception is near-infrared spectroscopy, although interpreting the measures of blood flow recorded with this technique remains controversial.
