New-onset psychogenic nonepileptic seizures after intracranial neurosurgery: a meta-analysis

Functional neurological symptom disorder refers to a state in which the normal functioning of brain networks is affected, rather than any structural abnormalities. One of its manifestations is a condition termed psychogenic non-epileptic seizures (PNES), also known as functional or dissociative seizures [1]. These seizures are characterized by clinically similar events to epileptic seizures, although they do not have characteristically abnormal ictal electroencephalogram activities [2], which supports the theory that their occurrences are psychological in nature rather than epileptic.
