Abstract

Autism spectrum conditions (ASC) without intellectual disability are often diagnosed late in life. Little is known about co-occurring psychiatric disorders and differential diagnosis of ASC in adulthood, particularly with regard to personality disorders. What kind of comorbid psychiatric disorders occur in ASC? Which are the most prevalent differential diagnoses in a sample of patients who seek autism specific clinical diagnostics? 118 adults who were referred with a presumed diagnosis of autistic disorder, were diagnosed with autism specific instruments and the prevalence of further psychiatric disorders was investigated. 59 (50%) fulfilled the criteria of ASC. 36% of the individuals with ASC fulfilled also criteria for a DSM-IV axis-I psychiatric disorder. Affective disorders (24%) and social phobia (14%) were the most prevalent comorbid disorders. The most frequent differential diagnoses were depression, social phobia, paranoid, avoidant and narcissistic personality disorder.
