The present study identifies the prevalence and types of comorbid psychiatric disorders associated with Asperger syndrome (AS)/high-functioning autism (HFA) in a combined community- and clinic-based sample of fifty 9- to 16-year-old subjects using the Schedule for Affective Disorders and Schizophrenia for School-Age Children, Present and Lifetime Version. The level of functioning was estimated using the Children's Global Assessment Scale. The results support common (prevalence 74%) and often multiple comorbid psychiatric disorders in AS/HFA; behavioral disorders were shown in 44%, anxiety disorders in 42% and tic disorders in 26%. Oppositional defiant disorder, major depressive disorder and anxiety disorders as comorbid conditions indicated significantly lower levels of functioning. To target interventions, routine evaluation of psychiatric comorbidity in subjects with AS/HFA is emphasized.

We examined upper facial basic emotion recognition in 57 subjects with autism spectrum disorders (ASD) (M = 13.5 years) and 33 typically developing controls (M = 14.3 years) by using a standardized computer-aided measure (The Frankfurt Test and Training of Facial Affect Recognition, FEFA). The ASD group scored lower than controls on the total scores of FEFA and perceived ambiguous stimuli more often as a negative emotion. The older ASD group (> or =12 years) performed better than the younger ASD group (<12 years) on the blended emotions of FEFA. The results support the findings that individuals with ASD have difficulties in emotion recognition. However, older subjects with ASD seem to have better skills than younger subjects with ASD.

The aim of the study was to examine psychiatric symptoms in high-functioning adolescents with autism spectrum disorders reported by multiple informants. Forty-three 11- to 17-year-old adolescents with Asperger syndrome (AS) or high-functioning autism (HFA) and 217 typically developed adolescents completed the Youth Self-Report (YSR), while their parents completed the Child Behavior Checklist (CBCL). Teachers of adolescents with AS/HFA completed the Teacher Report Form (TRF). The informants reported significantly more psychiatric symptoms, especially withdrawn, anxious/depressed, social and attention problems, in adolescents with AS/HFA than in controls. In contrast to findings in the general population, the psychiatric problems of adolescents with AS/HFA are well acknowledged by multiple informants, including self-reports. However, anxiety and depressive symptoms were more commonly reported by adolescents with AS/HFA and their teachers than their parents, indicating that some emotional distress may be hidden from their parents.
