Psychogenic non-epileptic seizures among patients with functional neurological disorder: A case series from a Tanzanian referral hospital and literature review.

FNDs and PNES occur in Africa with age and gender distribution comparable to that found elsewhere. Although the percentage of FND cases overall was relatively low (2.2%), it is likely to be an underestimate because not all cases were recorded, and cases may be appropriately managed locally before patients are referred to a hospital. PNES was the most common phenotype of FNDs reported, and the African phenotype may be short-lived and self-limiting rather than chronic and recurrent, as reported elsewhere in the world. PNES presentations may also occur in clusters, which may have cultural significance in Africa. FNDs in Africa appear to be underreported, particularly over the last 30 years.
