The Psychogenic Non-epileptic Seizures (PNES) Task Force of the International League Against Epilepsy (ILAE) highlighted, important barriers to PNES service development in low income countries. This involves access to diagnosis and treatment (estimated to affect 60‐80% of patients), lack of diagnostic services, psychological treatment, and money for treatment, as well as stigma/lack of awareness or information.


To bridge such gaps in our country, we undertook an evidence based review to summarize current, clinical semiology, underlying aetiology, diagnosis, and management for patients with PNES. The intention is to improve the care of patients, and to steer discussion in clinical and scientific arena with the purpose of developing integrated services in low resource country. For   this review, Medline and PsycINFO database searches were undertaken for articles with keywords addressing nonepileptic seizures, pseudo-seizures, dissociative seizures and functional neurological disorder. We distilled the consensus views, most supported evidence to inform future service development.
