Question: What causes coma?


Mental alertness is maintained by the cerebral hemispheres in conjunction with the reticular activating system. Coma can be produced by diffuse disease of both cerebral hemispheres (usually a metabolic problem), disease in the brainstem that damages the reticular activating system, or a structural central nervous system (CNS) lesion that compresses the reticular activating system.
