This article guides parents of newly diagnosed autistic children, covering diagnosis, treatments, and supportive strategies. Autism Spectrum Disorder (ASD) is a lifelong developmental disability characterized by diverse behaviors and communication abilities. Diagnosis can start as early as 18 months but often occurs later. Although no cure exists, individualized treatment can improve functioning.
