Developmental disabilities are a group of conditions that begin at birth or during childhood. These conditions are chronic and impact an individual throughout their lifetime. Often, these difficulties occur in several important life activities such as self-care, learning, physical movement, speaking and understanding language. The most common developmental disabilities are autism and intellectual disabilities.
