Welcome to the 4th International Conference on Functional Neurological Disorder (June 19-21, 2022, Boston University). You can attend in-person or virtually. This multi-disciplinary conference brings together leading international experts, from a range of backgrounds including neurology, physiology, psychiatry, psychology and ethics. The conference is suitable for anyone wanting to improve their clinical skills in this area as well as those with a research interest in this fascinating and evolving topic. Functional disorders are the second commonest reason for a referral to a neurologist. The International Conference covers all functional neurological disorders, adding sessions on symptoms such as dizziness, speech and cognitive symptoms. The inaugural functional movement disorder meeting took place in 2004, with meetings to follow in 2009 and 2017, with supplemental standalone meetings on non-epileptic seizures.
