Functional Deficit

Meaning

A Functional Deficit is a measurable impairment in a specific physiological, cognitive, or motor capacity that limits an individual’s ability to perform activities of daily living or occupational tasks at an optimal level. This deficit is often the clinical manifestation of an underlying biochemical imbalance, hormonal deficiency, or chronic inflammatory state, rather than solely a structural injury. Examples include measurable declines in muscle strength, memory recall, or metabolic flexibility.
