Agitation is an unpleasant state of extreme arousal, increased tension , and irritability.

Alternative Names:



Extreme agitation can lead to:

Agitation can come on suddenly or over time. It can last for just a few minutes, or for weeks and even months. Pain, stress, and fever can all increase agitation.

Agitation by itself may not be a sign of a health problem. However, if other symptoms occur, it can be a sign of disease.

When agitation lasts for hours and there is changed awareness (altered consciousness), doctors often call this "delirium." Usually this has a medical cause such as alcohol withdrawal or an infection (in elderly adults). Older adults often have delirium while hospitalized.

Common Causes:

Causes of agitation include:

Agitation can be associated with:

Home Care:

  • A calm environment
  • Adequate lighting
  • Plenty of sleep
  • Stress-reducing measures

Don't restrain an overly agitated person if possible. This usually worsens the problem.

Call your health care provider if:

Contact your health care provider if you have prolonged or severe agitation, especially if you also have other unexplained symptoms.

To help better understand your agitation, your doctor may ask the following questions:

    • Are you extremely restless?
    • Are you trembling or twitching ?
  • Time pattern
    • Was the agitation a short episode?
    • Is the agitation persistent?
      • How long did it last -- for how many day(s)?
  • Aggravating factors
    • Does the agitation seem to be triggered by reminders of a traumatic event ?
    • Did you notice anything else that may have triggered agitation?
    • Do you take any medications, especially steroids or thyroid medicine?
    • How much alcohol do you drink?
    • How much caffeine do you drink?
    • Do you use any drugs, such as cocaine, narcotics, or "speed" (amphetamines)?
  • Other
    • What other symptoms do you have?
