A large portion of autism research dollars fund studies of genetics and cognition as opposed to autism treatments.
This review article describes the state of the current research on autism. There were 16,059 research articles on autism published from 1978 to 2008. About 8% of these papers are on treatments for autism. Other topics of research include genetics, intelligence, and neurobiology. The authors note that there is very little research on early and intensive behavioral interventions such as applied behavior analysis (ABA). Drug therapy is the autism therapy that is most studied and most published.
