Clinical manifestations and cultural correlates of psychogenic nonepileptic seizure symptoms: An Indian perspective

Abstract

Introduction: Patients with psychogenic nonepileptic seizures (PNES) tend to have more frequent and disabling seizures than those which true epilepsy and are often misdiagnosed as epilepsy due to lack of clear diagnostic criteria and variations in clinical semiology. This study was an attempt to improve the understanding and type of clinical manifestations seen in patients of PNES and the cultural beliefs regarding their symptoms. Materials and Methods: In this cross-sectional observational study, 71 patients diagnosed with PNES by neurologists on the basis of their clinical presentation and a two hours normal VEEG recording were enrolled in the study after ethics approval. The clinical manifestations of PNES were recorded in detail along with details of various cultural attributions of the patients to the symptoms which were recorded in open- and closed-ended questions. Results: Clinical manifestations included verbal unresponsiveness (74%), whole body rigidity (72%), upper limb (55%) and lower limb movements (39%), vocalizations and head movements in less than 25%, and automatisms in only 6 patients. Pelvic thrusting as a manifestation was seen in only one patient. Thirty-eight patients attributed their symptoms to being possessed by God/ghost/evil spirit; nine to black magic being done on them; twenty-four patients did not relate symptoms to religious beliefs. Sixty-two patients had visited faith healers. Conclusions: This study is the first of its kind which looks at various clinical presentations of PNES patients in order to assess if there is any cultural basis for the symptoms.
