As one can see in my article, Autism Symptoms there are quite a few behavioral symptoms for Autism Spectrum Disorder. I think though that it is important to look for the red flags of autism that often show themselves quite early during a child's development. At the web site for the Autism Society of America there is a list of red flags used as diagnostic tools to screen for autism. These five behaviors can occur early on in a child's development. These early warning signs do not automatically suggest autism, but are simply guidelines for parents, caregivers and family physicians. These early behaviors should be monitored in all children and if exist further evaluation should occur. This aids in early detection and treatment for Autism Spectrum Disorder. (ASD). Your child's pediatrician should be asking questions regarding your child's developmental milestones at each regular check-up and if you have any concerns share it with your doctor.
