Metabolic encephalopathies, common in critical care, cause global brain dysfunction. Early recognition and treating the underlying systemic illness are key for reversible outcomes.

Area of Science:

  • Critical care medicine
  • Neurology

Background:

  • Metabolic encephalopathies are frequent in critical care units.
  • Common types include septic, hypoxic-ischaemic, hepatic, and uraemic encephalopathies.
  • They manifest as global neurological dysfunction, from lethargy to coma.

Purpose of the Study:

  • To review metabolic encephalopathies in critical care.
  • To highlight their distinction from other neurological conditions.
  • To outline diagnostic and management strategies.

Main Methods:

  • Literature review of metabolic encephalopathies in critical care.
  • Discussion of diagnostic investigations including blood/CSF cultures, neuro-imaging, and EEG.
  • Emphasis on differentiating from structural lesions, CNS infections, and drug reactions.

Main Results:

  • Neurological symptoms can be early indicators of systemic illness.
  • Encephalopathy severity often correlates with systemic illness severity.
  • Electroencephalogram aids in grading encephalopathy severity.

Conclusions:

  • Most metabolic encephalopathies are reversible if treated promptly and without complications.
  • Treatment focuses on the underlying systemic illness and supportive care.
  • Distinguishing metabolic encephalopathy from other neurological insults is crucial.
