Complications of delirium may include the following:

  • Malnutrition, fluid and electrolyte abnormalities

  • Aspiration pneumonia

  • Pressure ulcers

  • Weakness, decreased mobility, and decreased function

  • Falls and combative behavior leading to injuries and fractures

  • Wandering and getting lost

  • Long-term cognitive impairment: Accumulating evidence shows that delirium is not only a transient, reversible acute confusion, but also can give rise to a persistent long-term cognitive impairment. [44]
