Statistics for 2009 show that a child is 18 times more likely to become diagnosed now than in the 1960’s. Based on this, it is important now more than ever for parents to know about the general behavior characteristics to look for. This page outlines those as determined by the DSM-IV, which is the tool used to officially diagnose children.

If you are looking for more of a general list, you may like the other pages I have provided available on the autism symptoms page. There are some that specifically focus on infants and toddlers, to help parents with identifying any noticeable signs in kids of all ages.

It’s hard to say exactly why there has been such a dramatic increase when definitive causes have not completely been determined at this time. Despite this there are many theories including a correlation between characteristics for autism and vaccinations.

The following provides autism signs as determined by the DSM-IV Revised Fourth Edition written by the American Psychiatric Association.

Treatment for Autism Signs

I have an entire page dedicated to listing the most up to date treatments, with descriptions for each, including DIR/Floortime and Relationship Development Intervention. There is also a section dedicated to ABA autism therapy, that will help explain the different types and how they can improve symptoms in children.

Picture exchange communication systems are also very commonly used since one of the most prominent autism signs is inability to communicate. If you are interested in learning more about these therapies, be sure to click on the link above.
