Functional Disturbance

Meaning

Functional disturbance refers to a deviation from the optimal physiological operation or balance within a biological system, where the underlying anatomical structure typically appears intact. This concept describes an impairment of function, rather than overt structural damage or disease, often preceding detectable pathological changes. It signifies a state where a system or organ is not performing its intended role efficiently, despite conventional diagnostic imaging or laboratory tests appearing within normal reference ranges for structural integrity.
