Understanding Autism

Autism Spectrum Disorder (ASD) is a complex developmental disorder that affects behavior, communication,
social skills, and learning. Typically, the symptoms of autism are diagnosed by the age of three, yet some

to be a spectrum because of the myriad of symptoms a person may have when they are diagnosed with
autism.

age-inappropriate levels of activity, lack of focus, and constant fidgeting. This disorder is often
diagnosed during childhood when parents and teachers notice the child is unable to sit still, listen to
instructions, and control their impulses.

On average, ADHD affects 5% of children and 3% of adults worldwide. The disorder may persist into
adulthood leading to low self-esteem, poor work performance, and trouble with personal relationships,

ADHD and build coping skills.
