Natural history of patients with psychogenic nonepileptic seizures


Psychogenic nonepileptic seizures (PNES) are episodes of altered responsiveness, movements, sensation, or experience, similar to epileptic seizures; but, they are not caused by abnormal electrical brain discharges and are assumed to be caused by a psychological process [1]. They are common occurrences in epilepsy centers [2]. However, misdiagnosis and delay in making a definite diagnosis are common in these patients [3]. There are few long-term studies on outcome of PNES and they suggest that many patients with PNES will continue to experience seizures in spite of receiving standard psychotherapeutic care [1,4].
