  • “Acute mental status change” is a vague and often misleading term that can encompass any change in a patient’s mood, behavior, psychomotor skills, and/or cognition.
    • This includes level of alertness and orientation.
  • Frequently, the term is used to describe delirium.
    • Some conceptualize delirium as resulting from a breakdown of brain function in individuals with impairments in brain connectivity and brain plasticity exposed to a stressor.
