Psychiatric Comorbidities in Functional Neurological Disorders and Psychogenic Non-Epileptic Seizures: Systematic Review and Policy Recommendations
This systematic review examines psychiatric comorbidities associated with Functional Neurological Disorders (FND) and Psychogenic Non-Epileptic Seizures (PNES), finding these are not autonomous conditions but develop alongside autism, borderline personality disorder, PTSD, and alexithymia. The authors propose a biopsychosocial model where early trauma, abuse, and neglect contribute to progressive neurological sensitivity, particularly in young female patients, and recommend improved assessment and integrated treatment policies.
