Neurological complications of malaria

Area of Science:

• Neurology
• Infectious Diseases
• Tropical Medicine

Background:

• Malaria, particularly Plasmodium falciparum infection, can cause severe neurological complications.
• Cerebral malaria, a form of acute encephalopathy, predominantly affects children and adolescents in endemic regions.
• Neurological complications contribute significantly to malaria's morbidity and mortality.

Purpose of the Study:

• To review the diverse neurological complications associated with malaria.
• To discuss the proposed pathogenetic mechanisms of cerebral malaria.
• To highlight the clinical spectrum and research perspectives of malaria-related neurological disorders.

Main Methods:

• Literature review of neurological complications in malaria.
• Analysis of pathogenetic hypotheses for cerebral malaria.
• Compilation of reported central nervous system and peripheral nervous system manifestations.

Main Results:

• Cerebral malaria has high mortality (up to 50%) and long-term morbidity, especially in children.
• Pathogenesis theories include microvascular obstruction (blood sludging) and immune-mediated inflammation.
• Other neurological issues include hypoglycemia, intracranial hemorrhage, arterial occlusion, ataxia, febrile seizures, epilepsy, and peripheral nerve involvement.

Conclusions:

• Malaria presents a wide range of neurological complications affecting the central and peripheral nervous systems.
• Understanding the pathogenesis of these neurological manifestations is crucial for effective treatment and prevention.
• Further clinical and experimental research is needed to explore these complex neurological sequelae.
