According to the National Institute of Neurological Disorders and Stroke, Autism Spectrum Disorder (ASD) "is a range of complex neurodevelopment disorders, characterized by social impairments, communication difficulties, and restricted, repetitive, and stereotyped patterns of behavior."
Attention Deficit Disorder (ADHD)
Attention deficit-hyperactivity disorder (ADHD) is a neurobehavioral disorder that affects 3-5 percent of all American children. It interferes with a person's ability to stay on a task and to exercise age-appropriate inhibition (cognitive alone or both cognitive and behavioral). Some of the warning signs of ADHD include failure to listen to instructions, inability to organize oneself and school work, fidgeting with hands and feet, talking too much, leaving projects, chores and homework unfinished, and having trouble paying attention to and responding to details. There are several types of ADHD: a predominantly inattentive subtype, a predominantly hyperactive-impulsive subtype, and a combined subtype. ADHD is usually diagnosed in childhood, although the condition can continue into the adult years.
Down Syndrome is a genetic condition that causes life-long delays in the way a child develops mentally and physically. An abnormality occurs during cellular division, called “non-disjucntion”, producing an extra copy of a chromosome. This extra genetic material effects the way a child develops.
