Autism and misdiagnosis: is early detection always accurate?

Autism is a brain-based disorder that involves disrupted social interactions and communication development along with stereotyped patterns of behaviors and interests. Early detection and intervention is crucial for children diagnosed with autism. While current trends in research and detection are leaning toward earlier diagnosis of the disorder, limited research exists to support that earlier diagnoses are accurate. The present study utilized archival research and interviews to examine the accuracy of early diagnosis in children identified as autistic using DSM-IV criteria, standard screening and diagnostic tools and genetic testing. Results indicated that genetic testing was the most reliable tool for accurately diagnosing autism. Earlier diagnosis of autism spectrum disorders has significant implications for primary healthcare providers and diagnostic and therapeutic service
