WHAT IS AUTISM? <ul><li>Very complex, often baffling developmental disability </li></ul><ul><li>First described by Leo Kanner in 1943 as early infantile autism </li></ul><ul><li>“ Auto” – children are “locked within themselves.” </li></ul><ul><li>For next 30 years, considered to be an emotional disturbance </li></ul>
  4. 4. WHAT IS AUTISM? <ul><li>3 categories for autism in IDEA? </li></ul><ul><li>Today, autism is a severe form of a broader group of disorders </li></ul><ul><li>These are referred to as pervasive developmental disorders (later) </li></ul><ul><li>Typically appears during the first 3 years of life </li></ul>
  5. 5. WHAT IS AUTISM? <ul><li>Very likely neurological in origin – not emotional, not the refrigerator mom </li></ul><ul><li>Prevalence figures vary widely (textbook says 5/10,000, but recent data say as high as 1/1000 or even 1/500. </li></ul><ul><li>4 times more prevalent in boys </li></ul><ul><li>No known racial, ethnic, or social boundaries </li></ul><ul><li>No relation to family income, lifestyle </li></ul>

  11. 11. 3. Pervasive Developmental Disorder – Not Otherwise Specified (PDD-NOS) <ul><li>Often referred to as atypical autism </li></ul><ul><li>Used when a child does not meet the criteria for a specific diagnosis, but there is severe and pervasive impairment in specified behaviors </li></ul>
  12. 12. 4.
