Complementary and alternative medicine use in adults with autism spectrum disorder in Germany: results from a multi-center survey.

BACKGROUND: Complementary and Alternative Medicine (CAM) is widely used both in the general population and for the treatment of somatic and psychiatric disorders. Studies on CAM use among patients with autism spectrum disorder (ASD) have so far only focused on children and adolescents. The aim of this study was to investigate patterns of CAM use among adults with ASD. METHODS: A questionnaire survey concerning current and lifetime use of CAM was distributed to adults with ASD between November 2015 and June 2016. Participants diagnosed by experienced clinicians using the current diagnostic gold standard were recruited from four ASD outpatient clinics in Germany. Questionnaire data was then linked to supplementary clinical data. RESULTS: The final sample consisted of 192 adults (response: 26.8%) with a mean age of 31.5 years (80% male; diagnoses: Asperger's syndrome (58%), childhood autism (27%), atypical autism (12%)). 45% of the respondents stated that they were currently using or had used at least one CAM modality in their life. Among the participants with lifetime CAM use, almost half had used two or more different types of CAM. Alternative medical systems (e.g. homeopathy, acupuncture) were most frequently used, followed by mind-body interventions (e.g. yoga, biofeedback, animal assisted therapy). Overall, 20% of respondents stated that they would like to try at least one listed CAM modality in the future. CONCLUSIONS: This is the first study on CAM use in adults with ASD, demonstrating considerable CAM use in this population. Given the popularity of CAM, patients should be informed about the effectiveness and potentially dangerous side effects of CAM treatments, as evidence for the majority of CAM methods in ASD is still limited.

Willingness to try and lifetime use of complementary and alternative medicine in children and adolescents with autism spectrum disorder in Germany: A survey of parents.

Regardless of their limited evidence and potential adverse effects, use of complementary and alternative medicine is common in children with autism spectrum disorder. Nevertheless, data on complementary and alternative medicine use in children with autism spectrum disorder in Germany are lacking. Therefore, a questionnaire survey on the use of complementary and alternative medicine was distributed to parents of children with autism spectrum disorder from three academic autism spectrum disorder outpatient clinics in Germany. Of 211 respondents, 46% stated that their child currently used or had ever used some form of complementary and alternative medicine in their life. The complementary and alternative medicine modalities most frequently used were manipulative and body-based methods (e.g. craniosacral therapy). And 18% of caregivers expressed willingness to try complementary and alternative medicine treatments for their child with autism spectrum disorder in the future, with mind-body interventions predominating. Health professionals should be aware of the considerable complementary and alternative medicine use prevalence among children with autism spectrum disorder and offer parents information about its effectiveness and potential side effects.

Use of complementary and alternative medicine in children and adolescents with autism spectrum disorder: A systematic review.

Despite limited evidence, complementary and alternative medicine treatments are popular in autism spectrum disorder. The aim of this review was to summarize the available evidence on complementary and alternative medicine use frequency in autism spectrum disorder. A systematic search of three electronic databases was performed. All research studies in English or German reporting data on the frequency of complementary and alternative medicine use in individuals with autism spectrum disorder were included. Two independent reviewers searched the literature, extracted information on study design and results, and assessed study quality using an established quality assessment tool. Twenty studies with a total of 9540 participants were included. The prevalence of any complementary and alternative medicine use ranged from 28% to 95% (median: 54%). Special diets or dietary supplements (including vitamins) were the most frequent complementary and alternative medicine treatments, ranking first in 75% of studies. There was some evidence for a higher prevalence of complementary and alternative medicine use in autism spectrum disorder compared to other psychiatric disorders and the general population. Approximately half of children and adolescents with autism spectrum disorder use complementary and alternative medicine. Doctors should be aware of this and should discuss complementary and alternative medicine use with patients and their carers, especially as the evidence is mixed and some complementary and alternative medicine treatments are potentially harmful.
