Dissociation and its biological and clinical associations in functional neurological disorder: systematic review and meta-analysis.

ABSTRACT:

Background

Studies have reported elevated rates of dissociative symptoms and comorbid dissociative disorders in functional neurological disorder (FND); however, a comprehensive review is lacking.
