Agitation

Overview

Agitation is a state of restlessness and inner tension in which a person feels unable to settle or relax. It often shows up as pacing, fidgeting, hand-wringing, irritability, rapid speech, or a sense of being on edge. Agitation ranges from mild unease to severe distress, and at its most intense it can include aggressive or unsafe behavior. It is a symptom rather than a diagnosis, reflecting something going on emotionally, mentally, or physically.

Agitation has many possible causes, from everyday stress and anxiety to medical and neurological conditions such as delirium, dementia, infections, or substance withdrawal. Identifying the cause is important because the right approach depends on it. Sudden agitation with confusion, especially in older adults or people who are unwell, can signal a medical emergency, and agitation involving thoughts of harming oneself or others always needs immediate help.

The speed of onset and the surrounding circumstances are particularly important. Agitation that develops suddenly over hours or a day, especially with confusion or in someone who is physically unwell, is more concerning for a medical cause such as delirium than agitation that builds gradually in the setting of long-standing anxiety or a mood disorder. It is also worth noticing simple but treatable triggers, since pain, hunger, a full bladder, an unfamiliar environment, or a recent change in medication can all set off or worsen agitation, particularly in older adults and those with dementia.

Common Causes

Agitation can stem from psychological, medical, and substance-related causes:

• Anxiety and stress: A common cause of restlessness and tension.
• Delirium: Sudden confusion and agitation, often from infection, medication, or illness, especially in older adults.
• Dementia: Agitation can occur as part of the condition or be triggered by discomfort or change.
• Substance use or withdrawal: From alcohol, drugs, or stopping certain medications.
• Mental health conditions: Such as depression, bipolar disorder, or psychosis.
• Medical problems: Pain, low blood sugar, low oxygen, thyroid problems, or infections.

Some medications and excessive caffeine can also cause or worsen agitation.

Associated Symptoms

The symptoms accompanying agitation help reveal the cause:

• Confusion or disorientation, especially with delirium
• Anxiety, racing thoughts, or a pounding heart
• Irritability, anger, or aggressive behavior
• Pacing, fidgeting, or an inability to sit still
• Difficulty sleeping
• Sweating, tremor, or rapid breathing with withdrawal or medical causes

Agitation with sudden confusion, fever, severe headache, chest pain, or thoughts of harming oneself or others is a medical emergency.

Diagnosis & Evaluation

A clinician evaluates agitation by looking for an underlying cause, particularly any medical emergency. This may include:

• History and examination: Reviewing recent changes, medications, substance use, and other symptoms.
• Vital signs and blood tests: To check for infection, blood sugar, oxygen, and organ function.
• Medication review: To identify drugs that could be contributing.
• Mental health assessment: When a psychiatric cause is suspected.
• Imaging: Such as a brain scan if a neurological cause is possible.

Because new agitation in someone who is unwell or older can reflect a serious medical problem, a thorough check is important.

Treatment & Management

Treatment focuses on the underlying cause along with calming, supportive measures:

• Treating medical causes: Such as infections, low blood sugar, low oxygen, or pain.
• Managing delirium: Addressing the trigger, reorienting the person, and ensuring a calm environment.
• Mental health treatment: Therapy and medication for anxiety, mood, or psychotic disorders.
• Withdrawal management: Supervised treatment for alcohol or drug withdrawal.
• Calm environment: Reducing noise, providing reassurance, and ensuring safety.
• Medication: Sometimes used short-term for severe agitation under medical supervision.

For agitation in dementia, identifying and easing triggers such as pain, hunger, or confusion is often key.

Self-Care & Prevention

• Manage stress with relaxation, breathing exercises, and regular routines
• Limit caffeine, alcohol, and other stimulants
• Maintain regular sleep and meals
• Keep familiar, calm surroundings for people prone to confusion
• Take medications as prescribed and review them with a clinician
• Seek support early for anxiety, mood, or substance concerns

When to See a Doctor

See a clinician if agitation is persistent, recurrent, or affecting daily life or relationships. Seek emergency care right away for:

• Sudden agitation with confusion, especially in an older or unwell person
• Thoughts of harming oneself or others
• Agitation with fever, severe headache, chest pain, or trouble breathing
• Agitation during drug or alcohol withdrawal with sweating, tremor, or hallucinations

If someone is at immediate risk of harm, call emergency services or a crisis line. Support is available and these situations are treatable.
