How Sleep Patterns Change in Alzheimer’s Patients – Managing Sleep Problems

Caring for someone with Alzheimer’s can be tough, day and night. Sleep issues affect up to 25% of those with mild to moderate dementia. This number jumps to 50% for those with severe stages. The Alzheimer’s Association says these problems come from damage to the brain damage that affects sleep.

As Alzheimer’s gets worse, sleep patterns change a lot. These changes are more common and intense than those seen in normal aging. People with Alzheimer’s might wake up a lot at night, get confused about the time, feel restless in the evening or even sundown.

Dealing with sleep issues in Alzheimer’s takes patience and the right support. You’re First Home Care in Houston, Texas offers in-home care services. Their caregivers know how to make bedtime routines calmer and safer for those with Alzheimer’s.

Understanding Sleep Disturbances in People with Alzheimer’s Disease

Sleep problems affect up to 70% of people with dementia. This makes nights hard for both patients and caregivers. Scientists are trying to understand why these sleep disorders happen. They know Alzheimer’s disease affects brain areas that control sleep-wake cycles.

Why Sleep Problems Occur in Alzheimer’s Patients

Your brain produces proteins that build up during Alzheimer’s disease. These proteins harm brain cells that control sleep. Studies show a big drop in both REM (dreaming) and non-REM (deep) sleep in Alzheimer’s patients.

Several factors make sleep hard:

• Mental and physical exhaustion from daily activities
• Changes in your body’s internal clock (circadian rhythm)
• Reduced production of melatonin, the sleep hormone
• Confusion between day and night

The Reciprocal Relationship Between Sleep and Alzheimer’s

Research from the Knight Alzheimer’s Disease Research Center shows a two-way link between poor sleep at night and disease progression. Losing just one night of quality sleep may make cognitive symptoms worse the next day. This creates a cycle where poor sleep speeds up brain changes, and brain changes disrupt sleep even more.

Sleep Stages Affected by Alzheimer’s Disease

Alzheimer’s disease affects all sleep stages. Deep sleep, which helps restore your body and consolidate memories, decreases a lot. REM sleep, important for emotional processing and learning, becomes broken up. These sleep changes in dementia often start early and get worse as the disease gets worse.

How Sleep Patterns Change in Alzheimer’s Patients

Caring for someone with Alzheimer’s means noticing big changes in their sleep. These changes affect both nighttime sleep and daytime alertness. Understanding these shifts helps you care better and manage tough behaviors linked to disrupted sleep.

Difficulty Sleeping and Fragmented Sleep

Your loved one might wake up many times at night. This broken sleep means they stay awake for long periods when they should be sleeping. In later stages, they could spend up to 40% of their night awake.

These frequent awakenings leave them tired but unable to sleep well again.

Daytime Napping and Sleep-Wake Cycle Disruption

The natural sleep-wake cycle gets mixed up in Alzheimer’s patients. You might see them nap a lot during the day but stay awake at night. This can get really extreme, with some people sleeping when others are awake and staying alert when everyone else is resting.  Days and nights get mixed up.

Sundowning and Evening Restlessness

Sundowning happens in many Alzheimer’s patients as the day turns to evening. You might see more confusion, anxiety, and agitation. Some get restless or aggressive. Night wandering is a big safety risk during these times.

Creating a calm evening routine can help lessen sundowning symptoms.

Changes in REM Sleep and Deep Sleep Stages

Brain changes in Alzheimer’s lead to less slow-wave sleep and reduced rapid eye movement. These deep sleep stages are key for memory and physical repair. Without enough REM and deep sleep, your loved one might get more confused and restless.

They might call out, toss and turn, or get up a lot at night.

Medical Factors Contributing to Poor Sleep Quality

When caring for someone with Alzheimer’s, poor sleep often comes from sleep disorders. These need medical help. Knowing these factors helps you work with doctors to improve sleep.

Sleep Apnea in Alzheimer’s Patients

Many with Alzheimer’s have obstructive sleep apnea. This makes breathing stop and start, lowering oxygen levels. It disrupts sleep and can make thinking problems worse.

Signs include loud snoring, what seems like holding their breath then gasping for air, and feeling very tired during the day.

Sleep apnea is a big concern because it harms brain function. Doctors might suggest a sleep study to find out. Treatments include CPAP machines and special sleeping positions.

Restless Leg Syndrome and Sleep Disruption

Restless legs syndrome makes legs feel like they’re crawling or tingling. It makes you want to move a lot, making it hard to sleep. It gets worse in the evening, messing up bedtime.  Talk with their doctor about iron or magnesium levels; it may be something as simple as this.  If not, their doctor may be able to prescribe a treatment to help. 

Depression and Its Effects on Sleep

Depression often goes with dementia, including vascular dementia. It can make you wake up early, have trouble falling asleep, or sleep too much. Treating depression can help sleep improve.

Your doctor might suggest antidepressants or therapy for both conditions.

Non-Drug Approaches to Improve Sleep in Dementia

Creating a peaceful sleep routine is key when caring for someone with dementia. The National Institutes of Health suggest trying natural methods first. This helps your loved one sleep better without needing drugs.

Keep mealtimes and bedtime the same every day. This helps your body’s internal clock stay healthy. Also, morning sunlight exposure is great. Try to get your loved one outside or near bright windows early.

Daily exercise is good for sleep, but time it right. Do physical activities early in the day. Avoid exercise four hours before bedtime to help your body relax.

The bedroom’s environment is important for sleep. Keep it cool and use soft nightlights. Small comfort items like a favorite blanket can offer security. Don’t have TVs in the bedroom and use the bed only for sleep.

Be mindful of what your loved one eats during the day. Avoid caffeine, alcohol, and nicotine, which can disrupt sleep. If they take medications like donepezil or rivastigmine, give them earlier in the day. This prevents sleep problems at night.

Sleep Medications and Treatment Options for Alzheimer’s Patients

Managing sleep issues in older adults with dementia can be tough. Non-drug methods should be your first choice. But sometimes sleep medications are needed. Knowing the treatments for sleep changes helps you make better care decisions for your loved one.

When to Consider Sleep Medications

Think about sleep medicine only after non-drug methods fail. If your loved one has disruptive nighttime behaviors, sleep meds might be right. Talk to your doctor if sleep problems severely affect daily life or caregiver well-being.

Types of Sleep Medications Used in Dementia Care

Several types of sleep medications are used for dementia patients:

Melatonin, your body’s natural sleep hormone, may help with sundowning. It’s gentler than prescription meds and a good first try.

Risks and Benefits of Sleep Medicines

Studies show sleep meds don’t always improve sleep quality in older adults with dementia. They can increase fall risks and cause confusion. Antipsychotics have serious warnings because they can raise stroke and death risks in dementia patients.

FDA-Approved Treatments for Sleep Changes

Belsomra (suvorexant) is FDA-approved for mild-to-moderate Alzheimer’s disease insomnia. It blocks orexin, a brain chemical that keeps you awake. Start with the lowest dose and increase slowly if needed. Consult your physician as this is a controlled substance with potential unwanted side effects.  Regular checks help decide when to stop treatment once better sleep patterns are seen.

Conclusion

Managing sleep issues in Alzheimer’s disease takes patience and a mix of methods. You’ll need to change lifestyles and may need to get medical help for better sleep. Remember, sleep is key for both you and the person with dementia.

When someone with dementia wakes up at night, stay calm. They might need to use the bathroom or feel pain. Speak softly and guide them back to sleep. Keep the lights dim and avoid activities that might disturb or over stimulate them.

Quality sleep gets harder as Alzheimer’s worsens, but you’re not alone. The Alzheimer’s Society recommends getting help from family, friends, or professionals. Taking breaks helps you care better. Adjust your approach as needs change, with your healthcare team’s help.

Every Alzheimer’s journey is different, and what works for one might not for another. Keep talking to your doctors about sleep issues. They can help find the right balance of treatments and strategies. With the right support, you can improve sleep for everyone.
