My experience with autism sits very close to home. My 2 cousin’s ages 7 and 9 were both diagnosed with pdd-nos. Both girls were young when they were diagnosed but there symptoms did not start being recognized till the oldest was 3 the youngest was 2. We will use the name "Marie" for the oldest, and "Rose" for the youngest.
Their mom was noticing some strange behavior with Marie. She got stuck on things, such as watching a certain episode of a show over and over again for hours. She also didn't answer any who, what, where and why questions. She also had problems with touch. She did not like to be touched or hugged. Loud noises were an issue for her as well as transitions. She also had some what was thought to be defiant behaviors and did not have good eye contact. Her mother sat down with their pediatrician for a consultation. Mom asked for this because she was very worried about the "defiance".
Marie would not take no for an answer, would tantrum by banging her head and would not communicate. This is when the pediatrician, by asking questions about her behaviors, decided to refer them to the "Ladders program". This program has since been renamed to "Lurie Center for Autism"(McDougle, 2013).
When mom first sat down with the clinician's and evaluators they started discussing "Rose" also and came to the conclusions that she also showed some signs of autism and should be evaluated also.
Tests, do not just take an hour. The process is lengthy
