Understanding Autism - Symptoms
What Are the Symptoms of Autism?
Symptoms of autism include:
- Extreme difficulty in learning language.
- Inappropriate response to people. A child with autism may avoid eye contact, resist being picked up or cuddled, and seem to tune out the world.
- Inability or reduced ability to play cooperatively with other children or to make friends.
- Inability to understand other people's feelings.
- Need for a rigid, highly structured routine -- and being very distressed by changes in routines.
- Extreme hyperactivity or unusual passivity, and extreme resistance to change.
- Repetitive body movements including pacing, hand flicking, twisting, spinning, rocking, or hitting oneself.
- Insensitivity to pain or lack of response to cold or heat.
- Impulsive behavior and no real fear of dangers.
- An unusual attachment to inanimate objects such as toys, strings, or spinning objects.
- Frequent crying and tantrums for no apparent reason.
- Peculiar speech patterns. An autistic child may use words without understanding their meanings.
- Abnormal responses to sensations such as light, sound, and touch. At times an autistic child may appear deaf. At other times the child may be extremely distressed by everyday noises.
- Some of these symptoms occur in children with other disabilities. Symptoms can change as the child grows older.
Autism Spectrum Disorders
The forms of autism are thought to overlap considerably. But the fact that there is wide variation in symptoms among children with autism led to the concept of autism spectrum disorder.
Autism seems to be on the rise, and autism spectrum disorders affect between two and six children out of every 1,000 in the U.S. It's unclear, though, whether the growing incidence of autism represents a real increase or just improved detection.
Early diagnosis of an autism spectrum disorder is important. That's because detection leads to treatment, and with early treatment, a child with autism can gain improved language and social skills.
