Heterogeneity of patients with functional/dissociative seizures: Three multidimensional profiles.

ABSTRACT:

Objective

Current concepts highlight the neurological and psychological heterogeneity of functional/dissociative seizures (FDS). However, it remains uncertain whether it is possible to distinguish between a limited number of subtypes of FDS disorders.
