Is there a morning version of sundowning? Understanding 'Sunrise Syndrome'

While 'sundowning' is well-known for causing evening agitation, many caregivers report similar confusion and anxiety in the morning. This phenomenon is sometimes called 'reverse sundowning' or 'sunrise syndrome', and experts confirm that a version of sundowning affecting mornings does exist, often due to disrupted sleep-wake cycles.

Quick Summary

Yes, a morning version of sundowning, often termed 'sunrise syndrome' or 'reverse sundowning', can occur in elderly individuals, particularly those with dementia, due to circadian rhythm disruptions.

Key Points

• Morning Agitation is a Form of Sundowning: Symptoms of confusion and restlessness can occur in the morning, a phenomenon sometimes called 'sunrise syndrome' or 'reverse sundowning'.

• Circadian Rhythm Disruption is a Key Cause: The body's internal clock can become misaligned in dementia patients, leading to confusion upon waking.

• Triggers Include Fatigue, Medication, and Dehydration: Poor sleep, high morning cortisol, medication side effects, and lack of hydration can exacerbate morning symptoms.

• Light Therapy is an Effective Management Tool: Exposing the senior to bright light in the morning can help regulate their sleep-wake cycle and reduce confusion.

• Consistent Routine and Environment are Crucial: Maintaining a predictable daily schedule and a calm environment is essential for reducing anxiety and managing symptoms.

• Empathic Communication Helps Reorientation: Avoid arguing or harsh corrections. Instead, gently and calmly explain the time and situation to help them reorient.

• Professional Consultation is Recommended: Consulting a doctor can help identify underlying medical issues and manage medications that may be contributing to the problem.

Understanding Morning Agitation and Confusion

Caregivers often associate increased confusion and agitation in seniors with the late afternoon or evening hours, a condition known as sundowning. However, many have observed similar challenging behaviors upon waking, including disorientation, anxiety, and resistance to morning routines. While sundowning is a descriptive term rather than a formal diagnosis, experts acknowledge that these symptoms can happen at any time of day, and a pattern of increased cognitive impairment upon waking is common. This 'morning version of sundowning' can be equally distressing for both the senior and their caregiver.

What are the signs of 'sunrise syndrome'?

Symptoms that indicate a morning version of sundowning may include:

• Waking up disoriented and not recognizing one's location or caregiver.
• Increased anxiety or panic, particularly about the day ahead.
• Intense resistance to getting dressed, bathing, or eating breakfast.
• Hallucinations or delusional behavior, confusing dreams with reality.
• Sudden mood swings, from anger to withdrawal, shortly after waking.

These behaviors can stem from the underlying pathology of dementia and an inability to regulate internal body clocks, which control the sleep-wake cycle.

Why Do Symptoms Appear in the Morning?

The root cause of morning confusion and agitation in seniors is often multifactorial. While classic sundowning is theorized to be caused by end-of-day fatigue and fading light, the morning equivalent has distinct triggers.

Disruptions to Circadian Rhythm

The circadian rhythm, or the body's internal 24-hour clock, is frequently disrupted in people with dementia. Neurodegeneration in the brain's suprachiasmatic nucleus (SCN), which controls this clock, can lead to a confused sleep-wake cycle. Instead of the body naturally becoming more alert in the morning, it may struggle to differentiate between day and night, resulting in a state of grogginess and disorientation that is similar to the late-day confusion of sundowning.

Other Common Triggers

• Sleep Deprivation: A poor night's sleep can leave an elderly person feeling fatigued and more prone to anxiety and irritability upon waking.
• Increased Morning Cortisol: Stress hormone levels, such as cortisol, naturally rise in the morning. In sensitive or anxious individuals, this can heighten feelings of anxiety and agitation.
• Medication Effects: The timing of medication can play a significant role. The effects of some drugs may wear off overnight, or their side effects could cause morning confusion.
• Dehydration or Hunger: The body may be dehydrated or hungry after a night of no food or water, which can directly affect cognitive function.
• Environmental Changes: A change in environment, such as hospitalization or moving to a new care facility, can be incredibly disorienting and trigger morning confusion.
• Underlying Medical Issues: Hidden infections, like a urinary tract infection (UTI), can present as sudden confusion and delirium in older adults.

Comparison: Sundowning vs. 'Sunrise Syndrome'

Feature	Classic Sundowning	'Sunrise Syndrome'
Timing	Late afternoon/evening	Early morning/upon waking
Key Trigger	End-of-day fatigue, changes in light	Sleep-wake cycle disruption, high morning cortisol
Symptoms	Increased agitation, anxiety, restlessness, wandering	Waking up confused, resistant to routine, anxious
Environmental Factors	Shadows, low light levels, overstimulation	Poor sleep quality, nighttime dehydration
Management Focus	Evening routine, calming activities, bright lighting	Morning light exposure, consistent wake-up routine

Strategies for Managing Morning Symptoms

For caregivers dealing with morning confusion, a proactive approach can make a significant difference. The goal is to regulate the body's internal clock and reduce stressors.

• Use Light Therapy: Expose the senior to natural or bright, full-spectrum fluorescent light for a few hours each morning. This helps to reinforce the body's daytime signal and improve circadian rhythm function.
• Establish a Predictable Routine: A consistent daily schedule for waking, eating, and activities provides structure and predictability, which helps alleviate anxiety.
• Manage Diet and Hydration: Ensure the senior is well-hydrated throughout the night to prevent waking up thirsty or dehydrated. Avoid caffeine and sugar in the afternoon and evening.
• Encourage Daytime Activity: Mild exercise, such as a morning walk, helps burn off energy, boosts mood, and promotes better sleep at night, limiting excessive napping.
• Create a Calm Environment: Minimize noise and stress during the morning routine. Play calming music or engage in quiet conversation. Avoid rushing the person.
• Use Visual Aids: Large-print clocks that clearly show the time of day (morning, afternoon, evening) can help orient the person.

Creating a Calming Morning Routine

1. Gentle Awakening: Open the curtains to let in natural light and use a gentle, reassuring tone. Avoid loud noises or sudden movements that might startle them.
2. Hydration First: Offer a drink of water immediately. This can address any dehydration from the night and help the person feel more alert.
3. Simple First Task: Begin with a low-pressure activity, such as brushing hair or washing hands. Delay more demanding tasks like bathing until later in the day when they are more alert.
4. A Consistent Breakfast: Offer a nutritious breakfast at the same time every day. This helps solidify the morning routine and provide energy for the day.
5. Empathic Reorientation: If the person is confused, calmly explain the situation without arguing. For example, 'It's Tuesday morning, and we're getting ready for breakfast'. Link the time to emotionally relevant cues, like 'It's the time of day your grandson calls'.

When to Consult a Professional

While managing symptoms at home is often possible, it is essential to consult a healthcare professional. A doctor can rule out other medical causes for the confusion, review medications, and provide a tailored treatment plan. For example, a medication review may reveal that a side effect is exacerbating morning symptoms. The Alzheimer's Association is an authoritative resource for support and information on these symptoms, including those that manifest in the morning. (Learn more at alz.org). If symptoms worsen suddenly or if behavior becomes unsafe, it's crucial to seek immediate medical advice.

Conclusion

Experiencing a 'morning version of sundowning' is challenging but manageable with the right strategies. By understanding the potential causes, from circadian rhythm disruption to dehydration, caregivers can implement a calming, consistent routine that helps reorient the senior. Utilizing light therapy, managing medications, and ensuring basic needs are met are key steps. When in doubt, consulting a healthcare professional is the best way to address these complex behavioral changes and improve the quality of life for both the person with dementia and their caregiver.
