Understanding Sundowning Syndrome After Surgery
When an elderly loved one becomes confused or anxious as the sun sets following a surgical procedure, caregivers may be witnessing a form of delirium known as sundowning. This phenomenon is not a disease itself but a cluster of behavioral changes that can emerge or worsen during the transition from daylight to darkness. While most commonly associated with Alzheimer's and other forms of dementia, the stress of surgery and hospitalization can trigger these symptoms in seniors, even those without a prior dementia diagnosis.
Why Post-Surgical Recovery Triggers Sundowning
Several factors unique to the surgical experience can disrupt a senior's internal clock and mental state, leading to sundowning:
- Anesthesia: The effects of anesthesia can linger, contributing to post-operative cognitive dysfunction (POCD), a condition that can manifest as delirium or sundowning.
- Unfamiliar Environment: Being in a hospital or rehabilitation facility can be disorienting. The changing light, unfamiliar sounds, and lack of personal routine can heighten confusion.
- Sleep Deprivation: The constant noise and activity in a hospital setting often disrupt normal sleep-wake cycles, leading to fatigue that can trigger agitation in the evening.
- Pain and Medication: Uncontrolled pain and the side effects of certain medications can increase confusion and restlessness.
- Infection: Urinary tract infections or other post-surgical infections can cause a sudden change in mental status, which often presents as delirium and can exacerbate sundowning-like symptoms.
Symptoms of Post-Surgical Sundowning
The signs of sundowning can vary widely but generally become most apparent during the late afternoon and evening hours. Common symptoms include:
- Agitation and Anxiety: The individual may become restless, fidgety, or visibly distressed, often for no apparent reason.
- Confusion and Disorientation: They may not recognize familiar people, forget where they are, or have trouble following simple instructions.
- Pacing and Wandering: An increased need to move or walk around, sometimes with the intent to leave the room or building.
- Restlessness and Energy Surges: A reversal of the normal day-night cycle, with a person becoming more energetic and active in the evening.
- Aggression and Stubbornness: Increased irritability, hostility, or outright refusal to cooperate with care.
- Paranoia and Hallucinations: Expressing suspicious thoughts or seeing/hearing things that are not there.
Managing Post-Surgical Sundowning: A Multi-Pronged Approach
Managing sundowning involves a combination of environmental adjustments, routine, and patient reassurance. Caregivers play a vital role in implementing these strategies.
- Maintain a Consistent Routine:
- Structure the day with predictable times for meals, medications, and activities to provide a sense of security.
- Keep daytime naps short to promote better nighttime sleep.
- Optimize the Environment:
- Ensure plenty of bright, natural light during the day by keeping curtains open.
- In the evening, close curtains and use gentle, consistent indoor lighting to eliminate confusing shadows.
- Minimize stimulating noise and clutter in the evening, such as loud TV or radio.
- Provide Comfort and Reassurance:
- Create a calm and comfortable space with familiar items like blankets or family photos.
- Use a soft, reassuring voice to remind them of their location and the time.
- Consider gentle touch, like holding a hand, to provide a sense of connection.
- Manage Diet and Hydration:
- Ensure proper hydration, as dehydration can increase confusion.
- Avoid caffeine and sugary snacks in the afternoon and evening.
- Encourage Physical Activity:
- Gentle, doctor-approved exercise during the day, like a short walk, can improve sleep quality and reduce evening restlessness.
Sundowning vs. Postoperative Delirium: A Comparison
While often presenting with similar symptoms, understanding the nuances between sundowning and generalized delirium is important for proper management.
| Feature | Sundowning (Post-Op) | Postoperative Delirium |
|---|---|---|
| Timing | Primarily occurs in the late afternoon and evening, worsening as the sun goes down. | Can occur suddenly at any time of day or night. |
| Fluctuation | Symptoms show a clear, predictable pattern related to the time of day. | Mental status can fluctuate unpredictably throughout the day. |
| Cause | Often linked to disruption of the internal body clock due to environmental changes, stress, and fatigue. | Caused by an underlying medical issue, such as infection, metabolic changes, or medication side effects. |
| Resolution | Tends to resolve as the body adjusts to its routine and the acute phase of recovery passes. | Resolves when the underlying medical cause is identified and treated. |
| Underlying State | Often, but not always, associated with a pre-existing cognitive impairment like dementia. | Can affect anyone, but older patients and those with prior cognitive issues are at higher risk. |
Preventing Sundowning Symptoms Post-Surgery
Proactive measures can help minimize the risk and severity of sundowning symptoms.
Before Surgery
- Inform Medical Staff: Ensure your surgical team and anesthesiologist are aware of any pre-existing dementia or cognitive impairment.
- Pack Familiar Items: Prepare a bag with family photos, a favorite blanket, or a comfortable robe to bring a sense of home to the hospital room.
During Hospital Stay
- Encourage Early Mobilization: As soon as medically cleared, help the patient get up and move around to improve blood flow and combat inactivity.
- Promote Good Sleep Hygiene: Request that hospital staff limit nighttime interruptions for non-essential tasks to the extent possible.
- Provide Reassurance: Remind the patient where they are and why, offering calm and gentle reorientation as needed.
At Home During Recovery
- Manage the Environment: Replicate the strategies used in the hospital by controlling lighting and noise in the home.
- Plan Ahead: Meal prep and arrange household support so caregivers can focus on the patient.
- Monitor Triggers: Keep a log of what seems to exacerbate symptoms to identify specific patterns.

The Road to Recovery: A Final Word
Experiencing what is Sundowning syndrome after surgery is a common, though challenging, part of the post-operative journey for many seniors. With careful planning, environmental control, and consistent routines, caregivers can significantly alleviate symptoms and provide comfort during a vulnerable time. Remember that patience, reassurance, and seeking medical guidance for severe or persistent symptoms are your most valuable tools for navigating this condition.
