Psychogenic Nonepileptic Seizures in a Mother and Her Son–Fate or Chance?

Abstract

Shah V, Hamouda D and Masel T

Psychogenic Nonepileptic Seizures (PNES) are defined as typical seizure-like activities or behaviors without cortical epileptiform discharges. The diagnosis of PNES remains a challenge and continuous video electroencephalography (cEEG) remains the gold standard to differentiate between epileptic seizures and PNES. Despite advances made in our understanding of PNES, diagnosing and treating this well-known entity remains a challenge. 25% of patients with seizures will be misdiagnosed as having PNES or epileptic seizures even by certified Neurologists. Do patient characteristics and demographics increase our accuracy to diagnose PNES? We present a case of a mother and her son, both diagnosed with PNES by cEEG monitoring in our epilepsy monitoring unit. While familial prevalence of conversion disorders is reported in the literature, this will be the first case report describing the incidence of PNES in two members of the same family. Do psychogenic epilepsies run in families? Will the diagnosis of PNES in one family member increase the probability of PNES in their relatives with seizures? Larger patient pools need to be studied to draw a definite conclusion regarding our observation.
