  • Summary

    Psychogenic nonepileptic seizures (PNES) are paroxysms of altered sensory, cognitive, and/or motor manifestations with or without alteration of consciousness that may resemble epileptic seizures, but do not originate from epileptiform brain activity. One framework conceives PNES as arising from a biopsychosocial, multifactorial etiologic model. An unexpectedly high co-occurrence rate of PNES and mild traumatic brain injury (mTBI) has been reported. A causal relationship may be possible in many cases. In applying the biopsychosocial framework, this review discusses how TBI may subserve contributing roles as Predisposing, Precipitating, and Perpetuating factors in the development of PNES.
