Comorbidity of Autism Spectrum Disorder and Personality Disorders with Eating Disorders, PTSD, and Somatic Symptom Disorder: Clinical Challenges and Treatment Implications

This clinical review examines the prevalence and mechanisms underlying comorbidity between autism spectrum disorder, eating disorders, and PTSD when occurring alongside personality disorders, noting that such combinations typically increase symptom severity and suicide risk. Evidence-based treatments exist but novel approaches are needed, with future research prioritizing ASD-personality disorder trajectories and trauma-informed interventions addressing emotion dysregulation and patient engagement.
