What are the symptoms and signs of autism in children and adults?

The current Diagnosis and Statistical Manual of Mental Disorders-Fourth Edition, Treatment Revision (DSM-IV-TR) identifies three features that are associated with autism:

  • impairment in social interaction,
  • communication, and
  • behavior.

Impairment of social interaction

Individuals with autism fail to develop normal personal interactions in virtually every setting. This means that affected persons fail to form the normal social contacts that are such an important part of human development. This impairment may be so severe that it even affects the bonding between a mother and an infant. It is important to note that, contrary to popular belief, many, if not most, persons with this disorder are capable of showing affection, demonstrating affection bonding with their mothers or other caregivers. However, the ways in which individuals with autism demonstrate affection and bonding may differ greatly from the ways in which others do so. Their limited socialization may erroneously lead family members and health professionals away from considering the diagnosis of autism.

As the child develops, interaction with others continues to be abnormal. Affected behaviors can include eye contact, facial expressions, and body postures. There is usually an inability to develop normal peer and sibling relationships and the child often seems isolated. There may be little or no joy or interest in normal age-appropriate activities. Affected children or adults do not seek out peers for play or other social interactions. In severe cases, they may not even be aware of the presence of other individuals.
