Cerebral malaria. In rare cases, malaria can affect the brain. This is known as cerebral malaria and it can cause your brain to swell, sometimes leading to permanent brain damage. It can also cause seizures (fits) or coma (a state of unconsciousness).
Severe cases of malaria caused by P. falciparum can affect the brain and other organs, as blood cells infected with the parasite stick to the walls of tiny blood vessels and block the flow of blood and oxygen. In the brain, the condition can develop into cerebral malaria and lead to coma and, if not treated, to death.
