Autism is a developmental disability that usually shows up before age 3. Autism may be linked with a wide range of traits. These include:
Extreme resistance to changes in daily routines
Unusual responses to things such as touch
Inability to interact with environment
People with autism may have major problems with both speech and nonverbal communication. They may also find it very hard to interact socially. For these reasons, speech therapy is a central part of treatment for autism. Speech therapy can address a wide range of communication problems for people with autism.
There is considerable overlap among the different forms of autism. The wide variation in symptoms among children with autism, however, has led to the concept of autism spectrum disorder, or ASD.
ASDs affect one out of every 68 children in the U.S. They occur more often among boys than girls. While autism appears to be on the rise, it's unclear whether the growing number of diagnoses shows a real increase or comes from improved detection.
Early diagnosis is important. That's because early treatment...
Utter grunts, cries, shrieks, or throaty, harsh sounds
Hum or talk in a musical way
Babble with word-like sounds
Use foreign-sounding "words" or robotic-like speech
Parrot or often repeat what another person says (called echolalia)
Use the right phrases and sentences, but with an unexpressive tone of voice
About one out of three people with autism has trouble producing speech sounds to effectively communicate with others. The person's language, if present, is simply too hard to understand.
Communication problems. A person with autism may have one or more of these communication challenges:
Trouble with conversational skills, which include eye contact and gestures
Trouble understanding the meaning of words outside the context where they were learned
Memorization of things heard without knowing what's been said
Reliance on echolalia -- the repeating of another's words as they are being said -- as the main way to communicate
Little understanding of the meaning of words or symbols
Lack of creative language
Because of these challenges, a child with autism must do more than learn how to speak. The child also has to learn how to use language to communicate. This includes knowing how to hold a conversation. It also includes tuning into both verbal and nonverbal cues from other people -- such as facial expressions, tone of voice, and body language.
