Current Status of Functional Neurosurgery

Part of the Advances and Technical Standards in Neurosurgery book series (NEUROSURGERY, volume 10)


The term “functional” was used and occasionally continues to be used incorrectly to designate conversion or hysterical phenomena as well as psychosomatic disorders. However, the correct use of this term has been stressed by Hughlings Jackson95 who stated 100 years ago that functional is the adjective of the word function. Function, according to Hughlings Jackson, is related to physiology; functional changes are physiological changes and should be distinguished from the pathological changes producing them.
