I've seen kids who look low functioning at age 2 or 3 make huge progress and not look so bad by age 7-8. While these certainly help, it is debatable whether they help the child vs. the child's caretaker s more. In addition, when started in childhood the long term risk of developing complications from such meds such as tardive dyskinesia is HUGE and this is why we are generally very reluctant nowadays to start such meds in autistic childen unless there is just no other option. These things are total quackery. This argument over theory, however, is in some ways beside the point.
Women are usually carriers, and males are usually affected with the syndrome.
Most affected individuals have developmental delays - ranging from mild to severe, and many clinically fall into the Autism spectrum of disorders. While the majority of kids with autism spectrum disorders do NOT have Fragile X, the majority of Fragile X probably do have autistic characteristics. Undesired behaviors are ignored, not punished. However, as time goes on the the child learns the program, learning accelerates. This may sound difficult, but the rewards are worth it.
