Initially, only few symptoms of cerebral malaria show up in both children and adults. These include:

  • non-specific fever
  • impaired consciousness
  • convulsion and neurological abnormalities
  • coma that may last for three days at a stretch.

The main symptoms of cerebral malaria include:

  • persistent orthostatic hypotension chills
  • headache
  • muscle pain
  • low blood pressure
  • altered state of consciousness.

In cerebral malaria, attacks may occur every second day and may last for 6-10 hours. The symptoms usually occur in three stages:

  • Cold Stage: sensations of cold and extreme shivering. This may last for 1-2 hours.
  • Hot Stage: It is characterised by headaches, vomiting, seizures in young children and high fever i.e. up to 107°F. This may last for 3-4 hours.
  • Sweating Stage: It is characterised by profuse sweating and tiredness. This stage may last 2-4 hours.

Common signs of cerebral malaria include:

  • mild jaundice
  • anemia
  • enlargement of liver and spleen
  • kidney failure
  • blood in urine
  • rise in intracranial pressure
  • delirium and seizures
  • increased respiratory rate.

The signs of cerebral malaria may become fatal within a few days. Since the natural resistance of immune system is not helpful, one must immediately go for artificial treatments.
