PY - 2021 T2 - Neuropsychiatry and Behavioral Neurology: Principles and Practice AB - Patients with medically unexplained symptoms (MUS) are commonly seen in all medical practices, especially in neurology and psychiatry. MUS comprise up to one-third of new referrals to an ambulatory neurology clinic.1 Many of these patients suffer from a functional neurological symptom disorder (FNSD), a type of somatic symptom disorder also called conversion disorder or functional neurological disorder (FND). MUS is a term that implies physical complaints without a clear physiological explanation. However, in its diagnostic criteria, the DSM-5 de-emphasizes the issue of pathogenesis to avoid grounding the diagnosis in the absence of such explanation.
