OBJECTIVE: The objective of this study was to evaluate the prognostic significance of neurological manifestations in falciparum malaria. METHODS: We analyzed adult patients with malaria admitted from 2001 to 2003, diagnosed by asexual forms of Plasmodium falciparum in peripheral blood films and identified cases of malaria with neurological involvement. A patient was classified as having neurological involvement if they reported or had one or more of the following symptoms; headache, altered mental status, seizures, neck rigidity, brisk reflexes, cranial neuropathy and hyper or hypotonia. RESULTS: A total of 454 patients were included in the study. Out of these, 123 (27%) were diagnosed as complicated (severe) malaria and 331 (73%) as uncomplicated malaria at admission. Overall 70 (15.4%) patients had evidence of neurological involvement at initial evaluation. Twenty-seven patients out of 123 (22%) with complicated malaria and 43 patients out of 331 (13%) with uncomplicated malaria had neurological involvement. Over all, 16 (4%) patients died, 13 (11%) had complicated malaria (n=123) and 3 (1%) had uncomplicated malaria (n=381). Mortality in patients having neurological involvement (n=70) was 9 (13%) as compared to 7 (2%) in patients with malaria having no neurological involvement (n=384). This difference was statistically significant (p=0.012). Seizure was identified as predictor of mortality on Univariate analysis [OR 5.091 (1.835-14.121)]. CONCLUSION: Fifteen percent of patients with falciparum malaria admitted to our hospital had neurological symptoms and neurological involvement was associated with increased mortality.
