Functional neurology is a modality that aims to integrate all of the brain's sensory activities in order to treat a variety of clinical and subclinical symptoms. This modality draws from a number of complementary and alternative health therapies. Advocates claim that correcting neurological problems and restoring functionality in the body may be possible by participating in a variety of exercises whose aim is neurological integration. These exercises involve specific forms of or exposure to movement, scent, sound, light, and touch. Drugs and surgery are not a part of this modality.
