Functional neurology is based on the principles of neuroplasticity, the concept that involves adaptive structural and functional changes to the brain. In functional neurology we are less worried about what name to call what is going on with the client but rather focused on finding the physiology involved and seeing if we can make a change to that physiology in real time. It is the ability of the nervous system to change its activity in response to intrinsic or extrinsic stimuli by reorganizing its structure, functions, or connections.
