Intellectual and Developmental Disabilities are differences that are usually present at birth or in early life, and that uniquely affect the trajectory of the individual’s physical, intellectual, and/or emotional development. Many of these conditions affect multiple body parts or systems. Just as there is no single type of I/DD, there is no single cause for I/DD. Examples of how they impact individuals can be found at: https://pcsofca.com/blog/what-are-intellectual-and-developmental-disabilities-i-dd/
California is the only state in the USA that has an entitlement to services and supports for people with I/DD and their families; known as the Lanterman Developmental Disabilities Services Act, it creates a legal right for people with I/DD to receive services and supports, based on individual needs, to live as independent and productive lives as possible in the community. The California Department of Developmental Services (DDS) contracts with 21 Regional Centers throughout the state to coordinate services to over 400,000 individuals with I/DD and their families. The system of services and support for people with I/DD as well as the number of people being served, has grown, and changed dramatically since the enactment of the Lanterman Act in 1969.

The blue banner at the top reads, “I/DD” and below the umbrella are listed the names of different I/DD in blue caps text. From top to bottom and left to right they read, “down syndrome, adhd, cerebral palsy, fetal alcohol syndrome, muscular dystrophy, tourettes, spina bifida, fragile x syndrome, autism, turner syndrome, prader-willi syndrome, lead poisoning, epilepsy.” At the bottom of the image in the grass there is a white border box with white caps text inside that reads, “non-exhaustive list of examples.”
