Which of the following is an example of a biomedical approach for autism?

The gluten-free diet is considered a biomedical approach for autism because it pertains to dietary interventions that aim to modify bodily functions or health conditions believed to be associated with autism. This strategy is based on the premise that certain dietary components, such as gluten (a protein found in wheat and other grains), might exacerbate symptoms in some individuals with autism. Advocates of this approach believe that removing gluten from the diet can lead to improvements in behavioral and health outcomes for some children on the autism spectrum.

Biomedical approaches can include a variety of interventions that focus on physiological changes and may involve nutrition, supplements, and medications to address underlying biochemical or physiological issues. This distinguishes the gluten-free diet from strategies like visual schedules, social skills training, and behavior modification, which are primarily psychological or behavioral techniques rather than biomedical interventions.
