[Functional Neurological Disorders - A Common but Often Unrecognized Diagnosis]

Functional Neurological Disorders - A Common but Often Unrecognized Diagnosis Abstract: Functional neurological disorders are frequent and diverse in the clinical presentation. Psychological factors are part of the development and perpetuation of symptoms; psychiatric comorbidities may be present, but are not an obligatory diagnostic criterion. The diagnosis is primarily made on the basis of anamnesis and positive clinical signs. The commonness and reversibility of the symptoms should be emphasised in the clinical consultation, and the positive clinical signs should be demonstrated. Science-based explanations as well as the bio-psycho-social model can help patients to understand their diagnosis, which is relevant for a successful therapeutic outcome. It is recommended to use the neutral and descriptive term "functional neurological disorder". Treatment of the potentially reversible disease will be interdisciplinary and multimodal.
