What is ICU psychosis?

ICU psychosis is a disorder in which patients in an intensive care unit (ICU) or a similar setting experience a cluster of serious psychiatric symptoms. Another term that may be used interchangeably for ICU psychosis is ICU syndrome. ICU psychosis is also a form of delirium, or acute brain failure.

What causes ICU psychosis?

Environmental Causes

  • Sensory deprivation: A patient being put in a room that often has no windows, and is away from family, friends, and all that is familiar and comforting.
  • Sleep disturbance and deprivation: The constant disturbance and noise with the hospital staff coming at all hours to check vital signs, give medications, etc.
  • Continuous light levels: Continuous disruption of the normal biorhythms with lights on continually (no reference to day or  night).
  • Stress: Patients in an ICU frequently feel the almost total loss of control over their life.
  • Lack of orientation: A patient's loss of time and date.
  • Medical monitoring: The continuous monitoring of the patient's vital signs, and the noise monitoring devices produce can be disturbing and create sensory overload.

Medical Causes

  • Pain which may not be adequately controlled in an ICU
  • Critical illness: The pathophysiology of the disease, illness or traumatic event - the stress on the body during an illness can cause a variety of symptoms.
  • Medication (drug) reaction or side effects: The administration of medications typically given to the patient in the hospital setting that they have not taken before.
  • Infection creating fever and toxins in the body.
  • Cumulative analgesia (the inability to feel pain while still conscious)

These attacks are a serious health problem in the U.S. At least 20% of adult Americans, or about 60 million people, will suffer from panic attacks at some point in their lives. About 1.7% of adult Americans, or about 3 million people, will have full-blown panic disorder at some time in their lives, twice as often for women than men.
