Which therapy for autism has been proven ineffective?

Secretin therapy is considered ineffective for the treatment of autism. Secretin is a hormone that is naturally produced in the body and is involved in the digestive process. Some proponents of secretin therapy suggested that it could help with the symptoms of autism by influencing gastrointestinal issues purported to be related to the condition. However, research studies and clinical trials have consistently shown that there is no significant evidence supporting the efficacy of secretin therapy in improving core autism symptoms or overall functioning.

In contrast, speech therapy, occupational therapy, and behavioral therapy have all been shown to provide benefits to individuals with autism. Speech therapy assists with communication skills, occupational therapy helps with daily living and sensory integration skills, and behavioral therapy, particularly applied behavior analysis (ABA), has a strong evidence base for improving behavioral and educational outcomes for many children with autism. These therapies are backed by research and are widely used in practice, illustrating their importance in supporting individuals on the autism spectrum.
