What is IDD?
Intellectual and Developmental Disabilities (IDD) affect thinking, physical development, or both. Some of the most common conditions include Down syndrome, autism, and cerebral palsy. In the U.S., 7.38 million people (2.2% of the population) live with an IDD.
That's millions of families navigating support systems, services, and everyday challenges.
When Does IDD Begin?
IDD typically appears during development, before age 18. There are many early signs that might include differences in how a child learns, moves, or interacts with others.
Some conditions are detectable as early as during pregnancy, others are only detectable after birth or even later in life.
How Does IDD Affect Daily Life?
IDD can affect various aspects of life, from learning and communication to self-care and social interactions. Each person's experience is unique, with different strengths and support needs.
What Support is Available?
Many resources and services exist to support individuals with IDD and their families. This includes educational support, healthcare services, community programs, and various therapies.
