Neurological complications following Plasmodium falciparum infection.
Several neurological complications are associated with severe falciparum malaria. Cerebral malaria is one of the most life-threatening complications. A few patients may experience a neurological syndrome after complete recovery from Plasmodium falciparum infection. In the literature especially the postmalaria neurological syndrome (PMNS), acute disseminated encephalomyelitis (ADEM) and delayed cerebellar ataxia have been reported. We describe a case of a 53-year-old woman who was readmitted after an adequately treated P. falciparum infection with word-finding difficulties, confusion and tremor. Peripheral blood smears were repeatedly negative for malarial parasites. The clinical features best fitted a PMNS. Because of the severity of the syndrome she was treated with high-dose prednisone. She recovered completely. The possibility of ADEM is also discussed. Aetiology of these syndromes is still unknown, but it could be mediated by an immunological mechanism. PMNS or ADEM must be considered when neurological signs and symptoms occur after recovery from a P. falciparum infection.
