There is a lot of confusion and misunderstanding in the terms for functional neurological disorders, functional neurosurgery and functional neurology (similar to chiropractic neurology) in daily academic and clinical situations. Functional neurological disorders represent a specific type of disease, where "functional" refers to the nature of the disease; functional neurosurgery is an emerging branch of neurosurgery, where "functional" refers to the restoration of function as a result of neurosurgical intervention; functional neurology is a branch of alternative medicine that integrates the theories of chiropractic neurology, rehabilitation, neurology, acupuncture and other disciplines.
