Area of Science:

  • Neurology
  • Critical Care Medicine

Background:

  • Coma presents significant diagnostic and therapeutic challenges in intensive care settings.
  • Impaired consciousness indicates severe brain dysfunction or injury.

Purpose of the Study:

  • To review the etiology, diagnosis, and outcomes of coma.
  • To propose an evidence-based approach for managing comatose patients.

Main Methods:

  • Comprehensive literature search of Medline and Cochrane databases.
  • Manual review of bibliographies from relevant articles and monographs.

Main Results:

  • Coma and impaired consciousness are linked to brainstem, diencephalon, or cerebral cortex dysfunction.
  • Substantial risks of mortality and disability are associated with these conditions.

Conclusions:

  • Management involves stabilizing vital functions to prevent secondary neurologic injury.
  • Etiological diagnosis and brain-directed therapies are essential.
  • Prognosis depends on etiology and can be predicted using clinical and electrophysiological data.
