What is Functional Neurological Disorder?
Functional Neurological Disorder is due to a problem with the functioning of the nervous system in a structurally normal brain. Functional symptoms are thought to derive from the brain’s inability to send and receive signals correctly, as the result of physical and/or psychological risk factors.
Functional Neurological Disorder is a term used to describe a variety of physical, sensory and cognitive symptoms that have yet to be explained by a recognised ‘organic’ disease. Functional neurological disorders are considered to be multifactorial, which means many different factors can contribute to the development of the disorder. The symptoms are real and can cause impairment in quality of life that is similar to and in some aspects worse than other neurological conditions. FND occupies a grey area between psychiatry and neurology that historically has failed to gain the interest of researchers and clinicians. The prevalence and potential reversibility of functional illness have peaked new research interests. New scientific findings are influencing how patients are diagnosed, treated, and creating an overall change in attitude toward Functional Neurological Disorder patients.
