Autism is a brain disorder in which communication and interaction with others are difficult. The symptoms of autism may range from total lack of communication with others to difficulty in understanding others' feelings. Because of the range of symptoms, this condition is now called autism spectrum disorder (ASD).
High-functioning autism (HFA) is at one end of the ASD spectrum. Signs and symptoms are less severe than with other forms of autism. In fact, a person with high-functioning autism usually has average or above-average intelligence. The differences from other forms of autism have led many psychiatrists to consider high-functioning autism as similar to or the same as Asperger's syndrome. However, usually children with HFA have language delays early on like other children with autism. Children with Asperger’s, though, don’t show classic language delays until they have enough spoken language to assess language difficulties.
Because there aren't specific medical tests for autism, it's best to get a diagnosis from a physician or psychologist who specializes in developmental disabilities and has experience diagnosing Autism Spectrum Disorders (ASDs).
The diagnosis of autism is made by taking into account the child's complete medical and behavioral history, lengthy observation of the child's behavior, and ruling out other problems that may cause some of the same symptoms. It is important to distinguish autism from other...
Whether it's labeled high-functioning autism or Asperger's syndrome, coping with this condition presents daily challenges for those who have it and for their family and friends.
What Are the Symptoms of High-Functioning Autism and Asperger's Syndrome?
Other than the difference in their language development, people with high-functioning autism and people with Asperger's syndrome share many similar characteristics. They typically have average or above-average intelligence. They may, though, show other behaviors and signs similar to what's seen with other types of autism. These include:
A delay in motor skills
A lack of skill in interacting with others
Little understanding of the abstract uses of language, such as humor or give-and-take in a conversation
Obsessive interest in specific items or information
Strong reactions to textures, smells, sounds, sights, or other stimuli that others might not even notice, such as a flickering light
Unlike people with other forms of autism, people with high-functioning autism or Asperger's syndrome want to be involved with others. They simply don't know how to go about it. They may not be able to understand others' emotions. They may not read facial expressions or body language well. As a result, they may be teased and often feel like social outcasts. The unwanted social isolation can lead to anxiety and depression.
