Psychiatric comorbidity significantly increases suicide risk among people with autism spectrum disorder (ASD) in Denmark. Studies show that individuals with ASD alone do not have substantially higher rates of suicide attempt or suicide compared to the general population. However, over 90% of those with ASD who attempted or died by suicide also had at least one additional psychiatric disorder such as anxiety, affective disorders, schizophrenia spectrum disorders, or ADHD.
This means psychiatric comorbidity is a major risk factor requiring targeted suicide prevention efforts. Females with ASD show particularly elevated suicide attempt rates. Tailored mental health interventions are crucial to address this increased risk. More information can be found at DRISP Research on Autism and Suicidal Behaviour.
