(HealthDay News) -- Autism, a complex neurological disease, often appears in infants as a lack of responsiveness to others.
The U.S. National Institute of Neurological Disorders and Stroke says symptoms of the disease include:
- Impaired social interaction, which can range from inability to connect with others, to an obsessive focusing on one thing to the exclusion of anything else.
- Problems with verbal or nonverbal communication.
- Repetitive behaviors, such as rocking or twirling.
- Failing to respond to one's name and avoiding eye contact.
Researchers do not know what causes autism, though there may be a genetic link.
There is no cure for autism. But some with the disorder can improve with therapy.
