Which term best describes the developmental deficits seen in Intellectual Disability?

The term that best describes the developmental deficits seen in Intellectual Disability is one that indicates these deficits are evident from early development. Intellectual Disability typically manifests during the developmental period, which encompasses childhood and adolescence. These deficits affect cognitive functioning and adaptive behaviors, and they are recognized as part of an individual's developmental trajectory rather than emerging at a later stage in life.

Deficits in intellectual functioning, such as reasoning, problem-solving, and academic skills, alongside difficulties in adaptive functioning, like self-care and social skills, are foundational to this diagnosis. This early onset is crucial for differentiation from other conditions that may develop later in life due to various factors or be acquired through aging.

This understanding emphasizes that for a diagnosis of Intellectual Disability, the symptoms must be present and observable in the context of early development, making the correct answer the one that reflects this fundamental aspect of the condition.
