Neurological manifestations of malaria : an update.
Several neurological complications are associated with complicated and severe falciparum malaria. Cerebral malaria is one of the most dreaded complication. The children are particularly more vulnerable to have this complication. Despite availability of several potent antimalarial drugs in recent past, the mortality status has not changed. A large number of survivors are left with disabling neurological sequelae. Few patients may experience post-malaria neurological syndrome after recovery from complicated falciparum infection. Various psychiatric syndromes have been described either as early manifestation of cerebral malaria or part of post malaria neurological syndrome. From Indian subcontinent several patients of delayed cerebellar ataxia have also been described following recovery from clinical malaria. In paediatric patients, convulsions of cerebral malaria need to be differentiated from febrile convulsions. Falciparum malaria is also associated specifically with convulsions in uncomplicated patients of malaria. Several isolated case reports of various other neurological syndromes like peripheral neuropathies, various movement disorders, myelopathies and stroke like syndrome have been described. However association of these neurological manifestations with malaria remains doubtful.
