Down Syndrome

Down syndrome is a genetic condition caused by an extra copy of chromosome 21. It is present at birth and affects each child differently.

Children with Down syndrome may reach developmental milestones later than other children. They may need extra support with communication, learning, movement, and everyday skills. Every child with Down syndrome has their own strengths and abilities.

Under the New York State Early Intervention Program, Down syndrome is a diagnosed condition with a high probability of resulting in developmental delay. Because of this, a child with Down syndrome is eligible for the Early Intervention Program.

Every child in the Early Intervention Program receives a multidisciplinary evaluation. The evaluation helps identify the child's strengths and needs and is used to develop an Individualized Family Service Plan (IFSP).

Early Intervention services should begin as soon as possible after a diagnosis of Down syndrome. Early support can help children build communication, movement, learning, social, and everyday living skills while helping families support their child's development.

If your child has been diagnosed with Down syndrome, you can refer your child directly to your county's Early Intervention Program to begin the evaluation process. Parents can make a referral if they have concerns about their child's development or if their child has a diagnosed condition.
