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).
Cerebral hypoxia. Cases of total oxygen deprivation are termed anoxia, which can be hypoxic in origin (reduced oxygen availability) or ischemic in origin (oxygen deprivation due to a disruption in blood flow). Brain injury as a result of oxygen deprivation either due to hypoxic or anoxic mechanisms are generally termed hypoxic/anoxic injuries (HAI). Hypoxic ischemic encephalopathy (HIE) is a condition that occurs when the entire brain is deprived of an adequate oxygen supply, but the deprivation is not total.
