The Ministry of Health, Government of Southern Sudan (MoH-GoSS), further investigated for NS in the Witto internally displaced persons (IDP) camp in Witto Payam in western Equatoria in September 2010. A total of 96 cases were registered, most aged between 5-20 years (highest in the age group 10-15 years). Head nodding, tonic-clonic partial seizures with secondary generalization and generalized seizures were reported. Based on the past two investigations, and available data, it was concluded that NS is a form of epilepsy with causes remaining obscure (9).
