Critically ill patients often experience brain dysfunction, even when awake. Routine cognitive assessments and revised care practices are crucial for improving recovery outcomes.

Area of Science:

  • Neuroscience
  • Critical Care Medicine
  • Psychiatry

Background:

  • Disease and therapies significantly impact brain function in critically ill patients.
  • Simple tools are now available for recognizing neurological and cognitive problems.
  • Neuropsychiatric and cognitive observations are vital for patient care and outcomes.

Purpose of the Study:

  • To review neuropsychiatric and cognitive observations relevant to critically ill patients.
  • To highlight the impact of critical illness on brain function.
  • To emphasize the need for routine cognitive assessments in critical care.

Main Methods:

  • This is a review article.
  • It synthesizes current knowledge on cognitive dysfunction in critical illness.

  • It focuses on practical observations and implications for patient care.

    • Main Results:

    • Delirium, particularly hypoactive forms, is common in the elderly critically ill.
    • Cognitive dysfunction has profound implications for patient management in and beyond the intensive care unit.
    • Even 'awake' patients may have significant brain dysfunction, alongside psychological disturbances and long-term issues like PTSD.

    Conclusions:

    • Routine assessment of cognitive function is essential for all critically ill patients.
    • Sedation and care practices require reassessment to avoid exacerbating cognitive problems.
    • Improving recovery from critical illness necessitates addressing both physical and psychological aspects, including enhanced post-intensive care unit rehabilitation.
