5, 6 FND can occur across the age spectrum and often coexists with other neurological conditions. Patients with FND often report additional associated symptoms, including chronic pain, fatigue, and gut and respiratory symptoms, and although psychiatric comorbid conditions and psychological stressors are common, they are not universal. Core symptoms include seizure‐like attacks, gait difficulties, tremor and other movement disorders, cognitive and speech issues, disordered vision, and abnormal function of other special senses. FND presents with various core neurological symptoms, often concurrently, and of duration varying from acute onset to decades.

In this perspective, we outline clinical, health resource and service delivery issues surrounding FND in Australia, and propose a way forward to improve the landscape for people experiencing FND and the clinicians who provide their care.įND - Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM‐5): 3 conversion disorder (functional neurological symptom disorder) International Classification of Diseases, 11th revision (ICD‐11): F44 (dissociative neurological symptom disorder) 4 - is the occurrence of neurological symptoms due to malfunction, rather than neuropathology or neurological disease, of the nervous system. FND can be understood as somatisation presenting with neurological symptoms, and as with all somatic symptom disorders, the high prevalence and associated health care costs demand a change in the way we deal with patients with FND.

For example, the TikTok tic has recently generated both academic and popular debate, 1 and FND after vaccination for coronavirus disease 2019 (COVID-19) 2 is an increasingly familiar reason for neurology consultation to Australian emergency departments.Īll practising doctors see somatic symptom (previously known as “somatoform”) disorders in their patients, and most experience some discomfort in making a clear diagnosis and undertaking management. The contemporary name for the neurological condition that Charcot called l’hystérie is “functional neurological disorder” (FND), a condition that is highly prevalent in neurology practice today, but also appears increasingly in popular culture. If legendary neurologist Professor Jean Marie Charcot worked in an Australian hospital in 2022, rather than in 19th century Paris, he might still be enthusiastic about at least one of his pet topics. High prevalence and associated health care and social costs demand a change in health care paradigms for functional neurological disorders Statistics,epidemiology and research design.Statistics, epidemiology and research design.
