What is defined as a disability occurring before the age of 22?

A developmental disability is a broad term that encompasses a range of physical and mental impairments that occur before the age of 22. These disabilities typically affect major life activities, including learning, language, mobility, and self-care. It's characterized by significant limitations in intellectual functioning and adaptive behavior.

Developmental disabilities can manifest in various forms, including conditions such as intellectual disabilities, autism spectrum disorders, and certain physical disabilities affecting daily function. The age threshold of 22 is significant because it aligns with the developmental milestones and educational services that are available under the Individuals with Disabilities Education Act (IDEA) in the United States, which ensures that individuals receive necessary support and education up until this age.

In contrast, other options presented do not fit this definition as they refer to conditions or issues that may occur at any age or are not classified as disabilities in the same manner. Postural hypotension, hypertension, and diabetes are medical conditions that involve physical health but are not characterized as developmental disabilities tied to age of onset.
