There is insufficient evidence to support a causal relationship between GLP-1 receptor agonists and the risk of other common mental illnesses, including ADHD, Anorexia Nervosa, Autism Spectrum Disorder, and PTSD.

Based on this genetic study, GLP-1 drugs do not appear to reduce the risk of ADHD, Anorexia, Autism, or PTSD. Patients with these conditions should not rely on GLP-1 medications as a treatment for their mental health symptoms. Further research is needed to confirm these negative findings.
