Facts about intellectual and developmental disabilities
- Every year approximately 50,000 teens with autism age out of school-based services and enter adulthood.
- One-third of people with autism have epilepsy.
- Over half of people with autism also have intellectual disability.
- Nearly half of those with autism wander or bolt from safety.
- Autism affects 1 in 37 boys and 1 in 151 girls (2018)
- The most common motor disability in childhood.
- Cerebral Palsy affects over 500,000 people in the U.S.
- It is caused by brain damage while the baby is in utero, during labor and delivery, or shortly after birth. Premature infants are at a higher risk of developing cerebral palsy.
- There are many different kinds of cerebral palsy, based on the body parts affected, ranging in severity.
- Many have co-existing medical conditions, such as hearing and vision impairments, seizures, cognitive disability, ADHD, behavioral issues, feeding problems, scoliosis, and others.
- Most children with cerebral palsy have average or above average intelligence. Many adults with cerebral palsy work as doctors, attorneys, teachers and more.
- Most children with cerebral palsy have the same life expectancy as anyone else.
- Down Syndrome is one of the most common chromosome abnormalities in humans, affecting 1 in 1,000 babies born each year.
- These individuals have an increased risk of other health problems, including congenital heart defects, epilepsy, leukemia, thyroid diseases, and mental disorders.
- Half of those with Down Syndrome have obstructive sleep apnea.
- Hearing and vision disorders occur in more than half those with Down Syndrome.
- Hip dislocations may occur without trauma in up to a third of individuals.
- Growth is slower and they are at increased risk for obesity.
- Social skills are generally strong and behavior problems are not as common as in individuals with other intellectual and developmental disabilities.
- Fragile X is a genetic disorder caused by changes in the fragile X mental retardation gene ( FMR1) that makes a protein necessary for normal brain development.
- Fragile X syndrome is the leading known cause of inherited intellectual disability.
- Fragile X syndrome occurs in both males and females.
- Males with FXS usually have some degree of intellectual disability, ranging from mild to severe. Females with FXS can have normal intelligence or some degree of intellectual disability.
- Fragile X syndrome is the leading known genetic cause of autism. Approximately 2-6% of children with autism are diagnosed with Fragile X syndrome.
- Approximately 1 in 3,600 to 4,000 males and approximately 1 in 4,000 to 6,000 females have the full mutation of Fragile X.
- People with Fragile X syndrome (FXS) can cause a variety of behaviors like shyness, anxiety, difficulty making eye contact, and short attention spans.
