Patient Perspective: Closing the Gap: Personal and Clinical Reflections on Functional Neurologic Disorder.

Functional neurological disorder (FND) is a neuropsychiatric disorder that manifests with involuntary neurologic symptoms because of a brain network dysfunction, arising from variable biopsychosocial etiologies. Symptoms have positive clinical features of inconsistency, like tremor entrainment or distractibility, and incongruence with typical or well-understood neurophysiology/neuroanatomy. FND is not a diagnosis of exclusion and diagnostic criteria are available for many FND phenotypes.
