Signs & Symptoms

Symptoms of Autism Spectrum Disorders usually show before the age of 3. According to Centers for Disease Control and Prevention (CDC), one third of half of parents of children with ASD noticed signs before third child's first birthday, and nearly 80% to 90% saw signs by 24 months of age. It is important to know that not all children with ASD show every single sign of autism. However, the impairments tend to make life very challenging for both the child and the family. Individuals with ASD usually show warning signs in the following areas: social, communication, and behaviors
