Psychogenic nonepileptic seizures and psychogenic movement disorders: two sides of the same coin?

Arq Neuropsiquiatr. 2014 Oct;72(10):793-802. doi: 10.1590/0004-282x20140111.


Psychogenic nonepileptic seizures (PNES) and psychogenic movement disorders (PMD) are commonly seen in Neurology practice and are categorized in the DSM-5 as functional neurological disorders/conversion disorders. This review encompasses historical and epidemiological data, clinical aspects, diagnostic criteria, treatment and prognosis of these rather challenging and often neglected patients. As a group they have puzzled generations of neurologists and psychiatrists and in some ways continue to do so, perhaps embodying and justifying the ultimate and necessary link between these specialties.
