What Stage of Dementia Brings Sundowning, and How to Manage Evenings

Sundowning refers to a pattern of increased confusion, agitation, restlessness or aggression that typically begins in the late afternoon or early evening. Many caregivers and families ask: what stage of dementia is sundowning most likely to appear? Understanding when sundowning emerges and how to manage it can help you create calmer, more predictable evenings for someone living with dementia.

Understanding Dementia Stages

Dementia progresses through several stages, from mild memory lapses to severe cognitive decline. The Global Deterioration Scale (GDS) or the seven-stage staging system for Alzheimer’s disease is often used:

1. Stage 1 (No Impairment): No noticeable memory problems.
2. Stage 2 (Very Mild Cognitive Decline): Minor forgetfulness, often labeled “normal aging.”
3. Stage 3 (Mild Cognitive Decline): Difficulties finding words, remembering names, planning routine tasks.
4. Stage 4 (Moderate Cognitive Decline): Requires help with complex tasks (e.g., finances, grocery shopping).
5. Stage 5 (Moderately Severe Cognitive Decline): Needs help choosing clothing; confusion about location or time.
6. Stage 6 (Severe Cognitive Decline): Personality changes, possible wandering, difficulty remembering personal history.
7. Stage 7 (Very Severe Cognitive Decline): Loss of ability to communicate, require full-time assistance.

What Stage of Dementia Is Sundowning?

• Sundowning most commonly appears in mid to late stages, particularly Stage 5 and Stage 6 of Alzheimer’s disease.
• In these stages, the person’s ability to process visual and auditory stimuli, regulate sleep-wake cycles and cope with stressors is significantly reduced.
• While sundowning can occasionally occur earlier, its frequency and intensity typically increase as dementia advances.

Why Sundowning Occurs

Several factors contribute to sundowning:

• Disrupted Circadian Rhythms: Damage to brain areas that control the sleep-wake cycle can cause confusion when daylight fades.
• Fatigue and Overstimulation: A long day of events or social interaction may overwhelm someone with dementia.
• Environmental Triggers: Low light, shadows, noise or unfamiliar surroundings can heighten anxiety.
• Medication Side Effects: Some drugs may interfere with sleep or cause agitation late in the day.
• Hunger, Thirst or Discomfort: Physical needs that go unmet can provoke restlessness.

Understanding these triggers helps you anticipate and reduce evening distress.

Signs of Sundowning

Watch for these common indicators in the late afternoon or early evening:

• Increasing confusion about time, place or identity
• Restlessness or pacing
• Irritability, anger or aggression
• Hallucinations or paranoia
• Repetitive questions or statements
• Difficulty falling asleep or staying asleep

Early recognition allows for timely interventions to ease agitation and improve comfort.

Managing Evenings: Practical Strategies

Creating a calm, predictable environment can lessen sundowning episodes. Consider these evidence-based approaches:

1. Establish a Consistent Evening Routine

• Keep wake-up, meal and bedtime schedules stable.
• Plan quiet, low-stimulation activities before dinner—soft music, looking through a photo album or gentle stretching.
• Avoid stimulating TV shows, radio programs or loud conversations late in the day.

2. Optimize Lighting and Environment

• Increase indoor lighting as daylight fades to reduce shadows.
• Close curtains early to eliminate confusing outside glare or moving shadows.
• Use a nightlight in the bedroom and hallway to prevent falls and disorientation.

3. Adjust Meals and Hydration

• Serve a light, well-balanced dinner at least 2–3 hours before bedtime.
• Limit caffeine, sugar and large amounts of liquids late in the day.
• Offer a soothing warm beverage (e.g., decaffeinated herbal tea) after dinner.

4. Encourage Daytime Activity

• Promote physical exercise—walking, chair exercises, simple stretching—during daylight hours.
• Plan short, engaging activities that match abilities (puzzles, folding laundry, watering plants).
• Exposure to natural sunlight helps reinforce normal sleep-wake cycles.

5. Provide Reassurance and Comfort

• Speak in a calm, reassuring tone; offer simple, clear explanations.
• Keep favorite objects or photographs within view to ground their sense of familiarity.
• If hallucinations occur, don’t argue; instead, acknowledge feelings (“I know that looks real to you”) and gently redirect attention.

6. Monitor Medications and Health

• Review medications with a physician or pharmacist for evening side effects.
• Treat pain, urinary tract infections or other acute issues promptly to avoid added stress.
• Track patterns of sundowning in a journal to share with the care team.

7. Use Relaxation Techniques

• Play soft, familiar music or nature sounds.
• Offer sensory objects—soft blankets, textured fabrics, a comforting stuffed animal.
• Practice simple breathing exercises together: inhale slowly for 4 seconds, exhale for 4 seconds.

When to Seek Additional Help

If sundowning:

• Puts the person or others at risk of injury
• Becomes severe or unpredictable
• Is accompanied by signs of serious medical issues (fever, difficulty breathing, sudden vision changes)

…then it’s time to consult a healthcare professional. You might also consider a free, online symptom check, using the doctor approved Ubie Symptom Checker to better understand any new or worsening symptoms.

Caring for the Caregiver

Supporting someone with sundowning can be emotionally and physically draining. To maintain your own well-being:

• Take regular breaks and ask friends or family to help with evenings if possible.
• Join a caregiver support group—online or in your community—to share tips and experiences.
• Practice stress-relief strategies: deep breathing, short walks, brief mindfulness exercises.

Key Takeaways

• What stage of dementia is sundowning? Most often mid to late stages (Stage 5–6).
• Sundowning is driven by sleep-wake cycle disruptions, fatigue, environment, medications and unmet needs.
• A stable routine, proper lighting, balanced meals, daytime activity and soothing techniques can reduce evening agitation.
• Track symptoms, adjust care plans, and involve medical professionals when necessary.
• Consider a free, online symptom check, using the doctor approved Ubie Symptom Checker to clarify new concerns.
• Always speak to a doctor about any life-threatening or serious health changes.

By understanding the timing and triggers of sundowning—and using structured, compassionate strategies—you can make evenings more comfortable and predictable for someone living with dementia. Remember: if anything feels unsafe or life-threatening, seek medical attention immediately.
