6.1.1: What Is a Developmental Disability?
A disability is an impairment of functioning. Functional impairments may be physical (affect the body) or cognitive (affect mental functioning). A developmental disability is a disability that may affect physical, cognitive, learning, language, or behavioral development (CDC, 2015c). This means that there may be a developmental delay in normal development (how a person grows and functions) or an impairment of functioning (the person may not be able to function according to normal developmental processes). Developmental disabilities occur across all gender, racial, ethnic, and socioeconomic groups. According to the CDC (2015c), about 1 in 6 children have a developmental disability or a developmental delay.
Developmental disabilities begin in young childhood, may impact a child’s ability to function in one or more areas, and may continue throughout the person’s life. Parents, caregivers, teachers, and medical professionals may notice that a child is not progressing according to normal developmental milestones. Developmental milestones are things that a child typically does around a certain age (CDC, 2015b). For example, around 18 months old, a child is able to walk, is beginning to feed themselves, and can say several words (CDC, 2015b). Around 5 years old, a child typically speaks clearly, can print letters and numbers, is able to toilet themselves, and can do things such as hop, skip, and jump (CDC, 2015b). When parents and caregivers notice their child is not reaching typical developmental milestones, they may express their concern to a medical professional. The medical professional can assess the child using a variety of Developmental Screening Tools.
