Art Interventions for Children With Autism Spectrum Disorder: A Scoping Review.

IMPORTANCE: Autism spectrum disorder (ASD) is a neurological condition characterized by impairments in social interaction, communication, and behavior. Occupational therapy practitioners use creative arts interventions for children with ASD, but relevant evidence for these interventions is lacking. OBJECTIVE: To provide occupational therapists evidence of the benefit of creative arts interventions for children with ASD by evaluating treatment efficacy and connecting the evidence with the Occupational Therapy Practice Framework: Domain and Process (4th ed.; OTPF-4). DATA SOURCES: We searched peer-reviewed articles in six databases: CINAHL, Cochrane, PubMed, Ovid, PsycInfo, and Scopus. Eighteen articles published between 2000 and 2020 met Level 1b or 2b evidence criteria and were retrieved for full review; 15 were included in this scoping review. STUDY SELECTION AND DATA COLLECTION: We used Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to extract data. Inclusion criteria were as follows: (1) Level 1b or 2b study; (2) quantitative data; (3) published in English; (4) population of children (ages <18 yr); (5) primary diagnosis of ASD; and (6) creative arts intervention in the forms of drawing, painting, or coloring; music; or theater. FINDINGS: Creative arts interventions benefited children with ASD in two OTPF-4 areas (process and social interaction) pertaining to the Performance Skills domain and one OTPF-4 area (body functions) pertaining to the Client Factors domain. We found similar effects for group and individual intervention sessions, and significant improvements required multiple sessions. CONCLUSIONS AND RELEVANCE: Our findings provide evidence for the efficacy of creative arts interventions to enhance occupation-based outcomes for children with ASD. What This Article Adds: Our findings support occupational therapy practitioners' use of creative arts interventions to improve OTPF-4-based client factors and process and social interaction skills for children with ASD.

Effects of immunization with heat-killed Mycobacterium vaccae on autism spectrum disorder-like behavior and epileptogenesis in a rat model of comorbid autism and epilepsy.

Autism spectrum disorders (ASDs) and epilepsy are often comorbid. The basis for this co-occurrence remains unknown; however, inflammatory stressors during development are a shared risk factor. To explore this association, we tested the effect of repeated immunizations using a heat-killed preparation of the stress-protective immunoregulatory microbe Mycobacterium vaccae NCTC 11,659 (M. vaccae) on the behavioral and epileptogenic consequences of the combined stress-terbutaline (ST) rat model of ASD-like behavior/epilepsy. Repeated immunization of the dam with M. vaccae during pregnancy, followed by immunization of the pups after terbutaline injections, prevented the expression of ASD-like behavior but did not appear to protect against, and may have even enhanced, the spontaneous epileptogenic effects of ST. Maternal M. vaccae injections transferred an anti-inflammatory immunophenotype to offspring, and repeated injections across development prevented ST-induced increases in microglial density at early developmental time points in a region-specific manner. Despite epidemiological comorbidity between ASD/epileptic conditions and shared environmental risk factors, our results suggest that the expression of ASD-like behaviors, but perhaps not epileptogenesis, is sensitive to early anti-inflammatory intervention. These data provide support for the exploration of immunoregulatory strategies to prevent the negative neurodevelopmental behavioral effects of stressors during early critical periods.
