• Some are never able to speak or their speech is limited.  Picture cards, hand-held communication devices, computers, or other assistive techniques may aid communication.
• The onset of speech may begin at the typical age range, or even earlier than usual, but may be followed by a loss or plateau in the use of words.  Parents often become concerned about delays when the child is about 18-24 months of age.
• Receptive language (what they understand) and/or expressive language (what they say) are often delayed.  Receptive language delays are due at least in part to difficulties with auditory processing (making sense).
• Limitations in reciprocal speech often results in talking at rather than with someone.  Speech is more likely to be used to respond to rather than to initiate communication.
• Communication differences may include: echolalia (repeating what they have heard, either immediately or after a delay); concrete thinking; pedantic speech; repetitive questions; persistent monologues about favorite interests without regard for the listener's response.  Most of these language issues are a part of pragmatic language, including facial expressions, gestures, body language, and the unspoken nuances of language that give meaning to what we communicate.

What we presently understand about autism is that early, correct diagnosis leading to appropriate early intensive education and treatment offers the best opportunity for individuals with Autism Spectrum Disorders to reach their potential.
