Autism spectrum disorder (ASD) is a complex neurological and developmental disorder that begins early in life and affects how a person acts and interacts with others, communicates, and learns. ASD affects the structure and function of the brain and nervous system. Because it affects development, ASD is called a developmental disorder.
The symptoms of one person with autism can be very different from the symptoms of another person with autism. Health care providers think of autism as a spectrum disorder—which means that there is a range of similar features in different people with the disorder.1 One person with autism may have mild symptoms, while another may have more serious symptoms, but they both have autism spectrum ...
Currently, there is no medication that can cure autism spectrum disorder (ASD) or all of its symptoms. But some medications can help treat certain symptoms associated with ASD, especially certain behaviors. NICHD does not endorse or support the use of any medications not approved by the U.S. Food and Drug Administration (FDA) for treating symptoms of autism or other conditions.
ASD is a complex developmental disorder that affects how a person behaves, interacts with others, communicates, and learns. NICHD is one of many federal agencies and NIH Institutes working to understand ASD.

Scientists don't know exactly what causes autism spectrum disorder (ASD). Autism was first described in the 1940s, but very little was known about it until the last few decades. Even today, there is a great deal that we don't know about autism. Because the disorder is so complex and no two people with autism are exactly alike, there are probably many causes for autism. It is also likely that ...
Research shows that early diagnosis of and interventions for autism are more likely to have major long-term positive effects on symptoms and later skills.1,2,3,4,5 Autism spectrum disorder (ASD) can sometimes be diagnosed in children before they are 2 years of age. Some children with ASD whose development seems typical up to that point begin to regress just before or sometime during age 2 years.6
