Autism & Autism Spectrum Disorder (ASD)
People with autism experience social deficits, communication problems and have repetitive or restricted behaviors, with an onset in at least one area by age 3. It may or may not be associated with language delays or intellectual disability. An estimated 1.5 million individuals in the U.S. and tens of millions of people worldwide are affected by autism. While there is no medical test to diagnose autism, a diagnosis is based on observed behavior, educational and psychological testing. Get more information on autism and autism spectrum disorders.
Down syndrome is a genetic condition that causes delays in physical and intellectual development. The majority of children with Down syndrome have mild to moderate intellectual disabilities. It occurs in approximately one in every 800 live births, making it the most frequently occurring chromosomal disorder. Although individuals with Down syndrome have distinct physical characteristics, generally they are more similar to the average person in the community than they are different.

Fetal Alcohol Spectrum Disorder (FASD)
FASD describes the broad spectrum of effects that can occur in an individual whose mother drank alcohol during pregnancy. FASD can cause physical and mental disabilities of varying levels of severity (including intellectual disability). The good news is FAS is not hereditary and can only occur if a woman drinks alcohol during her pregnancy. There is no cure for this condition and it does not appear to get better with age. However, early identification can help children receive services that maximize their potential. Get more information on fetal alcohol spectrum disorder.
People with intellectual disabilities generally have a lessened mental capability which affects their ability to reason, plan, solve problems, think abstractly, comprehend complex ideas, learn quickly, and learn from experience. Studies show that somewhere between 1% and 3% of Americans have intellectual disabilities. There are many causes of intellectual disabilities that include physical, genetic and/or social factors. The most common syndromes associated with intellectual disabilities are autism, Down syndrome, Fragile X syndrome and Fetal Alcohol Spectrum Disorder (FASD).

Shaken Baby Syndrome (SBS)/Abusive Head Trauma (AHT)
Shaken baby syndrome (SBS) or Abusive Head Trauma (AHT) is caused by vigorous shaking of an infant or young child by the arms, legs, chest or shoulders that can lead to brain damage, intellectual disability, speech and learning disabilities, paralysis, seizures, hearing loss and even death. One in four babies die as a result of this abuse, making it the most common cause of mortality and accounts for the most long-term disability in infants and young children due to physical abuse.
