Clinical Trials

Many recent research studies have focused on finding the earliest signs of autism spectrum disorder (ASD). These studies aim to help doctors diagnose children at a younger age so they can get needed interventions as quickly as possible.

For example, one early sign of ASD may be increased head size or rapid head growth. Brain imaging studies have shown that abnormal brain development beginning in an infant’s first months may have a role in ASD. This theory suggests that genetic defects in growth factors, which direct proper brain development, cause the brain abnormalities seen in autism. It’s possible that an infant’s sudden, rapid head growth may be an early warning signal, which could help in early diagnosis and treatment or possible prevention of ASD. Current studies on ASD treatment are exploring many approaches, such as:

You can read about future research plans on the Interagency Autism Coordinating Committee’s (IACC’s) website . The IACC is made up of representatives of Federal agencies and members of the public and coordinates efforts within the U.S. Department of Health and Human Services concerning ASD.
