Post-malarial neurological syndrome in a Gambian adult residing in the Gambia: a case report and a review of literature

BACKGROUND: Post malarial neurological syndrome (PMNS) occurs as a sequel of cerebral malaria which is the most deadly form of severe malaria. In holo-endemic regions (areas of high malarial transmission) all forms of severe malaria as well as cerebral malaria usually occur in children and those who are semi or non-immune like pregnant women, migrants as well as tourists. It also occurs in hypo-endemic regions (areas of limited malarial transmission with low immunity) and malaria- free zones. Survivors however may have neurologic complications after recovery. PMNS has been reported in many parts of the world. Being a sequel to cerebral malaria, it is uncommon in adults who were born and reside in a holo-endemic region all their lives. CASE REPORT: This is the case of an 18 year old Gambian who has lived in The Gambia all his life that had PMNS five days after recovery from cerebral malaria. METHODS: This was a predominantly web based literature search. The search comprise all case reports, original articles and reviews on PMNS or neurological deficits associated with malaria or noted after malaria infection. The search engines used were Google, Yahoo and Google scholar. RESULTS: A total of 62 papers were found. These were used for this review of the literature. CONCLUSION: Cerebral malaria also occurs in adults in holo-endemic areas though rare and some of the survivors may develop PMNS. It is commoner in the youth age group. There is need for further studies since the youth may be a possible new ‘vulnerable group’ in holoendemic areas. This may lead to the widening the targeted group for malaria control in the regions of high malarial transmission.
