Functional neurological disorder (FND) presents with a range of neurological symptoms. Therefore, these patients are usually referred to the neurology team, although mental health liaison teams are also commonly involved in their care as in-patients. This article gives an overview of FND in adults, its diagnosis and management strategies, in the acute hospital. It discusses the common diagnoses it can be mistaken for, some techniques for psychoeducation and the value of the patient perspective. It emphasises the significance of clear communication, appropriate use of resources and considerate discharge planning. The role of liaison psychiatry is key, as an advocate for an improved multidisciplinary approach, establishment of local integrated multidisciplinary pathways, enhanced education for all clinicians and ongoing research to optimise treatment. FND needs an individualised, patient-centred approach to address the complex needs of this patient cohort.
