What are developmental disabilities?

Developmental disabilities are conditions that are usually present at birth. They can affect a child's growth and development. These conditions can cause physical, learning, language, or behavior issues. They can include:

• Learning disabilities. These conditions affect the ability to learn.
• Autism spectrum disorder (ASD). This is a disorder that affects behavior, communication, and social skills.
• Cerebral palsy (CP). This is a condition that affects movement, coordination, and balance.
• Physical disabilities. These could include blindness or deafness.
• Conditions that can affect both physical and mental abilities. This could include Down syndrome.

These conditions can cause lifelong challenges in learning. Completing daily tasks may be difficult. Early treatment may help your child learn important skills and make the most of their strengths.

• Observing your child's behavior and how they interact with other people
• Testing your child's intellectual and school performance
