Sleep disorders are prevalent among the elderly, with a reported occurrence rate of 30% to 48%, according to the World Health Organization (WHO). Sleep disorders not only lead to mental fatigue but may also reduce immunity, increase depression and anxiety, and impact daily life and social activities. Insomnia is even associated with suicide, emphasizing the importance of addressing sleep issues in the elderly.

In this article, we will explore the common causes and assessment methods of sleep disorders in elderly individuals. We will also discuss the side effects of sleeping pills and some alternative treatments that may help improve sleep quality and quantity. Our goal is to provide you with useful information and practical tips to help you or your loved ones sleep better and live healthier.

Causes of Sleep Disorders in Elderly Individuals

Sleep disorders in the elderly often stem from multiple factors, combining various sleep disorders such as sleep apnea, rapid eye movement behavior disorder, emotional disorders, and the impact of medication side effects. It is recommended that elderly individuals with sleep disorders record their sleep habits, examine their lifestyle, and seek help from professionals for effective improvement.

Some of the common causes of sleep disorders in elderly individuals are:

  • Age-related changes in sleep patterns: As we age, our circadian rhythm, or internal clock, tends to shift earlier, making us sleepy earlier in the evening and wake up earlier in the morning. We also experience a decrease in the amount and quality of deep sleep, which is important for memory consolidation and physical restoration. These changes can make it harder to fall asleep, stay asleep, and feel refreshed in the morning.
  • Medical conditions and medications: Many older adults have chronic health problems, such as heart disease, diabetes, arthritis, or dementia, that can affect their sleep quality and quantity. Some of these conditions can cause pain, discomfort, breathing difficulties, or frequent urination, which can disrupt sleep. Additionally, some medications used to treat these conditions can have side effects that interfere with sleep, such as stimulating the nervous system, causing dry mouth, or altering the sleep cycle.
  • Psychological and emotional factors: Older adults may experience stress, anxiety, depression, or grief, which can affect their mood and sleep. Stress can cause insomnia, or difficulty falling or staying asleep, by increasing the levels of cortisol, a hormone that regulates the sleep-wake cycle. Anxiety and depression can also cause insomnia, as well as hypersomnia, or excessive daytime sleepiness. Grief, especially after the loss of a spouse or a close friend, can cause sleep disturbances, such as nightmares, difficulty falling asleep, or early morning awakenings.
  • Lifestyle and environmental factors: Older adults may have habits or surroundings that are not conducive to good sleep. For example, they may have irregular sleep schedules, nap too much during the day, consume too much caffeine or alcohol, or engage in stimulating activities before bed. They may also have poor sleep hygiene, such as sleeping in a noisy, bright, or uncomfortable environment, using electronic devices before bed, or not having a relaxing bedtime routine.

Assessment Methods of Sleep Disorders in Elderly Individuals

If you or your loved ones have trouble sleeping, it is important to seek professional help to diagnose the type and cause of the sleep disorder. There are different methods to assess the quality and quantity of sleep, each with its own advantages and limitations. Some of the common assessment methods are:

  • Polysomnography: This is the most comprehensive and accurate method of sleep assessment, as it measures various physiological parameters during sleep, such as brain waves, eye movements, muscle activity, heart rate, breathing, and oxygen levels. Polysomnography is usually performed in a sleep laboratory, where the patient is hooked up to electrodes and sensors and monitored throughout the night. Polysomnography can diagnose various sleep disorders, such as sleep apnea, periodic limb movement disorder, narcolepsy, and REM sleep behavior disorder.
  • Actigraphy: This is a simpler and less invasive method of sleep assessment, as it only measures the movement and activity of the patient during sleep and wakefulness. Actigraphy is performed by wearing a device, such as a wristwatch or a bracelet, that records the movement and activity data over a period of time, usually several days or weeks. Actigraphy can estimate the sleep-wake cycle, the total sleep time, the sleep efficiency, and the circadian rhythm of the patient. Actigraphy can be useful for assessing insomnia, circadian rhythm disorders, and daytime sleepiness.
  • Sleep diaries and questionnaires: These are subjective methods of sleep assessment, as they rely on the patient’s self-report of their sleep habits, quality, and problems. Sleep diaries and questionnaires can provide information about the patient’s sleep patterns, bedtime routines, daytime functioning, mood, and perceived sleep difficulties. Sleep diaries and questionnaires can be used to screen for sleep disorders, monitor the response to treatment, and identify factors that may affect sleep.
Method Pros Cons

  • May cause discomfort and anxiety for the patient
  • May not reflect the patient’s usual sleep environment and habits
Actigraphy
  • Simple and non-invasive
  • Relatively inexpensive and convenient
  • Can be performed at home over a long period of time
  • Can capture the patient’s natural sleep-wake cycle and circadian rhythm
  • Less accurate and reliable than polysomnography
  • Cannot measure sleep stages and quality
  • Cannot diagnose specific sleep disorders
  • May be affected by external factors, such as light, noise, or temperature
Sleep diaries and questionnaires
  • Easy and inexpensive to administer
  • Can provide information on the patient’s subjective sleep experience and daytime functioning
  • Can identify factors that may influence sleep
  • Can be used in combination with other methods
  • Depends on the patient’s memory and honesty
  • May not reflect the actual sleep duration and quality
  • May be influenced by the patient’s mood and expectations
  • May not capture the variability of sleep over time

Side Effects of Sleeping Pills

Sleeping pills are a common treatment option for elderly individuals with insomnia, but they also come with potential risks and side effects. Some of the common side effects of sleeping pills include:

  • Drowsiness, dizziness, and impaired balance during the day
  • Dry mouth, constipation, or diarrhea
  • Headache, nausea, or heartburn
  • Memory loss, confusion, or difficulty concentrating
  • Dependence, tolerance, or withdrawal symptoms
  • Allergic reactions, such as rash, swelling, or breathing problems
  • Parasomnias, such as sleepwalking, sleep eating, or sleep driving

Some of these side effects can be dangerous, especially for older adults who may have other health conditions or take other medications. Sleeping pills can also interact with other drugs, alcohol, or supplements, and increase the risk of falls, injuries, or accidents. Therefore, sleeping pills should be used with caution and under the guidance of a doctor.

According to a systematic review and network meta-analysis by Kwon et al. (2021), the most common side effects of sleeping pills among elderly individuals with insomnia were drowsiness, headache, and gastrointestinal problems. The authors also found that some non-pharmacological treatments, such as acupuncture, behavioral therapy, and cognitive behavioral therapy, were more effective and had fewer side effects than sleeping pills.

Alternative Treatments for Sleep Disorders in Elderly Individuals

As sleeping pills may not be suitable or effective for everyone, some elderly individuals with insomnia may seek alternative treatments that are more natural, holistic, or less invasive. Some of the alternative treatments that have been studied for sleep disorders in older adults include:

  • Acupuncture: This is a traditional Chinese medicine technique that involves inserting thin needles into specific points on the body to stimulate the flow of energy and promote healing. Acupuncture has been shown to improve sleep quality, reduce insomnia symptoms, and modulate the activity of the brain regions involved in sleep regulation (Yin et al., 2017).
  • Yoga: This is a mind-body practice that combines physical postures, breathing exercises, and meditation to enhance physical, mental, and spiritual well-being. Yoga has been found to improve sleep quality, reduce stress, and lower blood pressure in older adults with insomnia (Halpern et al., 2014).
  • Aromatherapy: This is the use of essential oils extracted from plants to create pleasant scents that can affect mood, cognition, and physiology. Aromatherapy has been reported to improve sleep quality, reduce anxiety, and induce relaxation in older adults with insomnia (Koulivand et al., 2013).
  • Herbs and supplements: These are natural substances that can have various effects on the body and mind. Some of the herbs and supplements that have been used for sleep disorders in older adults include melatonin, valerian, chamomile, lavender, and magnesium. However, the evidence for their efficacy and safety is mixed and inconclusive, and they may also interact with other medications or cause adverse reactions (Sarris et al., 2019).

These alternative treatments may offer some benefits for elderly individuals with insomnia, but they are not without limitations or drawbacks. They may not work for everyone, they may have variable quality or dosage, and they may lack rigorous scientific evidence or regulation. Therefore, before trying any alternative treatment, it is advisable to consult with a doctor and a qualified practitioner, and to inform them of any other treatments or conditions.

Conclusion

Sleep disorders are common and challenging problems for older adults, and they can have negative impacts on their health, quality of life, and well-being. While sleeping pills are often prescribed to treat insomnia, they may not be the best or the only solution for everyone. Sleeping pills can have serious side effects and risks, especially for older adults who may have other medical issues or take other drugs. Therefore, sleeping pills should be used with caution and under medical supervision.

Alternative treatments, such as acupuncture, yoga, aromatherapy, and herbs and supplements, may offer some advantages over sleeping pills, such as being more natural, holistic, or less invasive. However, they are not without limitations or drawbacks, such as being less effective, less consistent, or less regulated. They may also have their own side effects or interactions, and they may not work for everyone. Therefore, before trying any alternative treatment, it is important to consult with a doctor and a qualified practitioner, and to inform them of any other treatments or conditions.

The best treatment for sleep disorders in older adults may depend on the individual’s preferences, needs, and circumstances. A comprehensive and personalized approach that considers the causes, symptoms, and consequences of sleep disorders, as well as the benefits and risks of different treatments, may be the most effective and appropriate way to improve sleep quality and overall health in older adults.
