Background: Epilepsy is one of the most common neurological diseases. The coexistence of epilepsy and PNES poses a major challenge to neurologists and psychiatrists in the treatment and follow-up care of patients.
Methods: 33 Sudanese patients with epilepsy and concomitant psychogenic non epileptic seizure where included in this study and full detailed history of both epilepsy and PNES was obtained. The study was conducted in Daoud charity clinic during the period from May to July 2018
Results : Out of 33 patients 19 were males and 14 were females. Seven patients had focal epilepsy, 23 had generalized tonic clonic epilepsy (GTC), 2 had GTC with atypical absent seizure, and one had GTC with myoclonus.
Six patients experienced an attack of PNES after more than 1 year of being free of epilepsy, while 9 patients had PNES attack between 3 months to 1 year of the last attack of epilepsy, and 18 patients developed both PNES and epilepsy within less than 3 months.
The pattern of presentation of PNES was bizarre movements in 13 patients, abnormal behavior in 9 patients, while 11 patients experienced both bizarre movement and abnormal behavior note that all those 11 patients had GTC epilepsy.
Conclusion: Experiencing psychogenic non epileptic seizure (PNES) in patients with coexisting PNES and epilepsy is not affected by the epilepsy free period
