ABSTRACT

Background and objectives Psychotic symptoms, such as delusions and hallucinations, in autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) have been increasingly reported in recent literature. In the present study, the prevalence and duration of psychotic symptoms, comorbid psychotic disorders, and clinical characteristics of adults with ASD and ADHD were retrospectively examined via a chart review. Methods The participants were 98 adults (mean age, 28.5 years; 72 men) who were admitted to the psychiatric emergency wards of Showa University Karasuyama Hospital, and who were diagnosed with ASD and/or ADHD according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria. Results Among 69 individuals with ASD, 21 (30.4%) experienced psychotic symptoms, and among 29 individuals with ADHD, 5 (17.2%) exhibited psychosis. While all psychotic symptoms were classified as transient and none had comorbidity with schizophrenia and other psychotic disorders in adults with ADHD, 38.1% of psychosis was classified as prolonged and 10.3% had comorbidity with schizophrenia and other psychotic disorders in adults with ASD. Conclusion The results showed that a significant proportion of adults with ASD and ADHD experience psychosis during their course of illness, and provide evidence for the existence of a shared etiology between neurodevelopmental and psychotic disorders.

ABSTRACT

AIM: The purpose of this study was to examine the symptoms of autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) in the adult clinical population using the Autism-Spectrum Quotient (AQ) and the Adult ADHD Rating Scales self-report screening version (CAARS-S:SV). METHODS: We included 50 adults with ASD and 52 with ADHD diagnosed using the DSM-5 criteria. Clinical symptoms were evaluated using the AQ and CAARS-S:SV. RESULTS: The AQ score was elevated in the ADHD group and the CAARS scores were increased in the ASD group. Specifically, the total AQ score in adults with ADHD was lower than that in the ASD group, but was higher than that in controls. Similarly, the CAARS scores in adults with ASD were lower than in those with ADHD, but were higher than those in controls. No significant correlations were found between AQ, CAARS Inattention/Memory Problems, and CAARS Hyperactivity/Restlessness scores in both the ASD and ADHD groups. CONCLUSION: While adults with ASD and ADHD exhibited similar clinical symptoms, the absence of AQ-CAARS correlations suggests the need for examining factors other than the apparent similarity of clinical symptoms of the two disorders.

ABSTRACT

Recently, organic donor-acceptor (D-A) cocrystals have attracted special interest as functional materials because of their unique chemical and physical properties that are not exhibited by simple mixtures of their components. Herein, we report the preparation of one-dimensional novel D-A cocrystals from C60 and 5,10,15,20-tetrakis(3,5-dimethoxyphenyl)porphyrin (3,5-TPP); these cocrystals have near-infrared (NIR) light-sensing abilities, despite each of their component molecule individually having no NIR light-sensing properties. Micrometer-sized rectangular columnar C60-3,5-TPP cocrystals were produced by a simple liquid-liquid interfacial precipitation method. The cocrystals exhibit a new strong transition in the NIR region indicative of the existence of charge-transfer interactions between C60 and 3,5-TPP in the cocrystals. The C60-3,5-TPP cocrystals showed n-type transport characteristics with NIR light-sensing properties when the cocrystals were incorporated in bottom-gate/bottom-contact organic phototransistors, revealing that organic cocrystals with suitable charge-transfer interaction are useful as functional materials for the creation of novel NIR-light-sensing devices.
