Functional Neurology (FN) is an approach used by some chiropractors. One website proudly proclaims that Functional Neurology, sometimes referred to as Chiropractic Neurology, is a term used to describe a variety of evidence-based treatments relating to neurological disorders. And another one informs us that Functional neurology, aka chiropractic neurology, is a healthcare discipline that utilizes neuroplasticity and contemporary clinical neuroscience to both evaluate and rehabilitate patients that suffer from a complex neurological condition or simply want to optimize their performance. A comprehensive neurological examination is performed in order to determine which area of the nervous system is not functioning appropriately. A customized therapy program is then tailored to address each person’s individualized neurological dysfunction.
The specific therapeutic claims that are being made for FN by chiropractors are impressive. The following list is a non-exhaustive attempt to document some of the conditions which functional neurologists claim to be able to treat: ADD/ADHD, Alzheimer’s, Anxiety disorders, Asperger’s Syndrome, Autism, Balance disorders, Blackouts, Blindness, Brain Aging issues, Canal stenosis, Cerebellar disorders,Chronic pain disorders, Cervical myelopathy, Coma, Complex regional pain syndromes, Concentration issues, Depression, Diplopia, Dizziness, Double vision, Dyslexia, Dystonia, Epilepsy, Fainting, Headaches, Heart arrhythmias, Irritable bowel syndrome, Learning difficulties, Memory issues, Mental Health, Migraines, Motion sickness, Movement disorders, Multiple sclerosis, Neglect syndromes, Numbness, Parkinson’s disease, Peripheral neuropathies, Radicular/nerve root conditions, Reflex sympathetic dystrophy, Sexual dysfunction, Sleep apnea, Sleep problems, Snoring, Speech problems, Spinal cord compression, Squints/skew deviations of the eyes, Strokes, Syncope, Tinnitus, Tics, Tourette’s, Tremors, Vertigo and Visual disturbances.
Is any of this backed up by evidence?
A review of FN included 9 articles. The included studies were conducted on adults or children, symptomatic or not, and investigated various interventions consisting of single or multiple stimuli, of varied nature, all primarily said to be provided to stimulate brain areas. Conditions included attention deficit disorders, attention deficit and hyperactivity disorders, autism-spectrum disorders, cortical visual impairment, traumatic brain injury, and migraine. Balance and the “blind spot” were investigated in healthy subjects. Major design and methodological issues were identified in all 9 studies; only 4 were considered as (potentially) appropriate for further scrutiny.
The authors concluded that no robust evidence could be found in relation to the effect or benefit of the tested FN interventions.
In a nutshell: FN is yet another addition to chiro-quackery.
