Autism Spectrum Disorder is a neurodevelopmental disorder that presents itself differently in each child. Symptoms of the disorder vary in severity but are characterized by weaknesses in communication, social interactions and often daily living skills. Limited interests and repetitive behaviors are also characteristics of Autism Spectrum Disorder. The severity of one’s Autism Spectrum Disorder is generally determined by the degree to which communication and reciprocal language are effected, the need for “sameness” in activities and environment and the exhibiting of repeated or perseverative behaviors. Sometimes known as “stims”, examples of such behaviors are preoccupations, obsessions and physical movements such as hand flapping. Due to the spectrum nature of this disorder, many people diagnosed with ASD appear typical and go on to lead very productive lives, while others experience more difficulty integrating into their communities. Behavioral therapy beginning with Early Intervention is crucial in helping the effected child reach their greatest potential.
