  • Hello, this is Brenda Keller from the Section of Geriatrics and Gerontology at the University of Nebraska Medical Center. In these modules we will review sleep disorders in the Elderly.
  • In module 1 our objective is to understand the epidemiology of sleep disorders in the elderly. We review changes in the sleep cycle with aging and finally discuss the impact and evaluation of sleep disorders.
  • Sleep disorders are common in the elderly. Up to 40% of older Americans have difficulty sleeping at least a few nights per month. Insomnia can be difficulty falling asleep, difficulty staying asleep or not feeling restored by sleep.
  • In younger adults, the normal sleep pattern consists of a cycle of non-rem sleep (stages 1 to 4) lasting 45 to 60 minutes followed by REM sleep. In general, deep sleep –that is non-REM sleep stages 3 and 4-predominate the first third of the night and comprise 15-25% of the total nocturnal sleep time of young adults.
  • With age, however, there are changes in this pattern. Light sleep-(non-rem stages 1 and 2) increases with age and deep sleep decreases from 25% down to 3% of total sleep. Not only do older people have less time in stages 3 and 4 sleep, they are more easily awakened during deep sleep. These changes lead to more awakenings and fragmentation of sleep. In the otherwise healthy older person, slow-wave sleep may be completely absent, particularly in males. The amount of REM sleep is the same to slightly decreased in older people. The timing of sleep is also altered in older individuals. Loss of the neurons in the suprachiasmatic nucleus may account for the age related circadian phase shift. All of these changes lead to decreased sleep quality and efficiency.
  • Circadian rhythms, the cyclic daily patterns of physiologic changes, are altered with aging. These rhythms guide the production of hormones, the body’s temperature and the sleep/wake cycle. In aging the sleep/wake cycle advances due to changes in the core body temperature and decreased light exposure. A decrease in neurons in the suprachiasmatic nucleus also plays a role in this circadian shift. The suprachiasmatic nuclei are either of a pair of neuron clusters in the hypothalamus situated directly above the optic chiasm that receive photic input from the retina via the optic nerve. They regulate the body's circadian rhythms
  • This illustration demonstrates the effect of advanced phase circadian rhythm on sleep. In the younger person, sleepiness occurs around 10 pm, the person goes to bed and falls asleep and sleeps~8 hours and awakens with the sunshine at 6 am. In the older person, sleepiness occurs much earlier, around 6 pm, the person may fall asleep then, or go to bed around 10 pm, but because the shift in rhythms has occurred, they are wide awake around 3 or 4 am. Although they have had 8+ hours of sleep, they essentially wake up in the middle of the night. The sunshine is placed at 6 pm to remind us that sunshine exposure in the early evening may be helpful in shifting the rhythm back to standard phase.
  • The duration of sleep declines approximately 27 minutes for each decade of life after mid life until the 8 th decade of life.
  • Disrupted sleep has several negative consequences. These include: daytime sleepiness, impaired attention, slow response time and impaired memory and concentration. Performance is also decreased. In fact, mortality due to the common causes of death is twice as high for people with sleep disorders as it is for those who sleep well.
  • The evaluation for sleep problems is multifactorial. A careful sleep history can help you identify the frequency and severity of the problem. It can also help you identify those individuals that are sleepy because they are trying to get by on 2-3 hours of sleep per night. The timing of insomnia can be helpful to determine if the patient has difficulty falling asleep or staying asleep. The sleep environment is also crucial for a good night’s sleep. Lights, sounds and temperature all affect the quality of sleep. A review of sleep habits can help you identify the “night owl” who is now having sleeping problems after moving to the nursing home with a in bed by 9 and up at 6 policy. The daytime effects of the sleeplessness help to guide you in your therapeutic options. In the sleep history you will also want to elicit historical features of restless leg syndrome, periodic limb movement of sleep and obstructive sleep apnea. A collateral source history can be extremely helpful in these cases. Medical disorders leading to sleep problems include asthma, gastroesophageal reflux, congestive heart failure, epilepsy, and chronic pain syndromes. A good social history will provide you with information about stressors leading to an Adjustment disorder. This is one of the most common causes of acute insomnia. It is related to an anticipated or recent event (death of loved one, anxiety over a test). Excessive caffeine intake, or caffeine intake late in the day may contribute to insomnia. Although alcohol may induce sleep initially, it disrupts sleep later in the night. Drug abuse of amphetamines, ephedrine, caffeine, nicotine, and selective serotonin reuptake inhibitors such as Prozac may lead to sleep disturbance. It is important to review the effects of all patient medications on sleep. Psychiatric disorders such as depression, mania, and schizophrenia cause approximately one-third of chronic insomnia.
  • Non-pharmacological treatment has been found to improve symptoms in 70-80% of patients with primary insomnia. These effects tend to be long lasting, with studies showing retained effectiveness for 6 months after the treatment is completed.
  • Sleep hygiene is education about health and environmental practices that effect sleep. This strategy is used in conjunction with other techniques to improve sleep. A Sleep Hygiene Tips page is available for your use on the main page of this module.
  • Many factors affect sleep, both heath related factors and environmental factors. Knowledge about these factors can overcome sleeping problems in many cases. Diet can affect sleep in a variety of ways. Heavy meals within a few hours of bedtime can contribute to acid reflux. For some people caffeine, even in small amounts early in the day, can affect sleep 10-12 hours later. Others find that avoiding caffeine 6 hours before bedtime is enough to help sleep. An exercise program of brisk walking or low impact aerobics 30 minutes 4 times a week has been associated with improved sleep quality for older adults with moderate insomnia. It is best to not exercise within 4 hours of sleep time. Substance use and abuse is also associated with sleep problems. Although alcohol has sedative properties, and may speed the beginning of sleep, it actually increases the number of awakenings. Having a nice, quiet, comfortable, darkened room may be all that is needed to induce sleep for some people with insomnia. Bright lights, noises, and uncomfortable mattress in a room that is too hot or too cold can make sleep impossible. Correcting these environmental factors is far less expensive and safer than prescribing a pill.
  • Stimulus control reinforces the temporal and environmental cues for sleep onset. The patient should go to bed only when sleepy. The bed is to be used only for sleep, not for watching TV, reading, eating, etc. Cultivating pre-bedtime routines, such as warm milk, emptying the bladder and not going to bed hungry is helpful. The patient should arise at a regular time each morning, regardless of when they went to bed and napping should be avoided.
  • The rationale for sleep restriction is to decrease the amount of time in bed to increase the sleep efficiency. The only allowed time in bed is usually spent asleep. The maximum sleep restriction is 5 hours per night. The time in bed is then increased by 15 minutes per night. Like stimulus control, the wake up time is constant, however with sleep restriction, the bedtime is adjusted per protocol. Sleep restriction does allow for short afternoon naps.
  • Cognitive therapy involves identifying dysfunctional beliefs and attitudes about sleep and replaces them with adaptive substitutes. This helps to minimize anticipatory anxiety and arousal.
  • The paradoxical intention method of sleep management is based on the premise that performance anxiety inhibits sleep onset. It involves convincing the patient to engage in the feared behavior of staying awake. The theory is that if the patient stops trying to fall asleep and genuinely attempts to stay awake, sleep may come more easily.
  • Pharmacological treatment for primary insomnia is generally reserved for those who fail non-pharmacologic therapy. For individuals with secondary insomnia, treatment is focused on the underlying disease process. Treatment of depression with antidepressants, analgesic use for pain, and dopaminergic medications for restless leg syndrome and periodic limb movement of sleep are all effective in the management of secondary insomnia. Only those items on the left part of the screen have FDA approval for insomnia. Those items on the right column should be used with caution as their effectiveness and safety for the treatment of insomnia have not been established.
  • Several general precautions are given for the pharmacological treatment of insomnia. First, start with low doses and go slow with titration. Second, as needed dosing of medications is recommended as opposed to a scheduled dose of hypnotic. Thirdly, the majority of hypnotics are recommended for short term use only. Medications should be used in concert with the non-pharmacological methods discussed in module 2.
