Sleep disorders and wakefulness -
This condition is most common in adolescents. This makes it difficult to stay awake through the evening hours and people who have this kind of circadian rhythm sleep disorder often wake up much earlier than desired. Irregular Sleep Wake Disorder is most commonly seen in elderly patients with dementia and refers to a lack of rhythm in a person's sleep and wake cycle.
Sleep occurs irregularly throughout a hour period. The individual cannot sleep through the night and has difficulty maintaining wakefulness during the day.
Free-running disorder or non hour sleep-wake disorder is rare and seen more commonly in individuals with blindness. Bright morning light sunrise aligns our internal clock to the hour day. When light perception is absent, the sleep period drifts later and later each day, causing this disorder.
Jet Lag happens during air travel when we traverse time zones faster than our body clocks can adjust. This causes a mismatch between the preferred sleep and waking times and the destination sleep and waking times. You can learn more about our top recommendations for blue light blockers here.
For a doctor to diagnose a sleep disorder, they might ask you to fill out a sleep diary to track when you sleep and how much you get per night. They may also ask you to wear a motion sensor for 14 days to better understand your rest-activity patterns.
If you have trouble sleeping, your doctor will be looking for the following before giving an official diagnosis of insomnia :. With the proper therapy and medication, these disorders are manageable. The American Academy of Sleep Medicine recommends taking melatonin when your circadian rhythm is close to your desired sleep schedule.
Getting exposure to artificial sunlight for 30 to 90 minutes at a time can reset your internal clock and shift your sleeping patterns to a more desired schedule.
Over time, you can reduce light therapy to 15 minutes each day or use it only a few times during the week. Working out, even leisurely, is helpful to sleep. The Centers for Disease Control and Prevention CDC lists some habits you can fold in to sleep better at night.
Other strategies for sound sleep include:. Sleep is essential for living a happy and fulfilled life. You can also learn more about your recent sleeping habits by answering just a few questions. The amount of sleep each person needs depends on many factors, including age.

This results in difficulty falling asleep and waking up at times conducive to school and work. When the individual attempts to wake up earlier, they become sleep deprived and alertness may be impaired.
This condition is most common in adolescents. This makes it difficult to stay awake through the evening hours and people who have this kind of circadian rhythm sleep disorder often wake up much earlier than desired.
Irregular Sleep Wake Disorder is most commonly seen in elderly patients with dementia and refers to a lack of rhythm in a person's sleep and wake cycle.

Free-running disorder or non hour sleep-wake disorder is rare and seen more commonly in individuals with blindness. Bright morning light sunrise aligns our internal clock to the hour day.
Ganglion cells contain a photopigment called melanopsin and transmit signals to the suprachiasmatic nuclei through the retinohypothalamic tract.
The suprachiasmatic nuclei then process this information and stimulate the pineal gland to release melatonin. Melatonin increases in the evening in response to dim light and peaks around 3 hours before waking.
Melatonin receptors are found primarily in the retina, the pars tuberalis of the pituitary gland, and the suprachiasmatic nuclei.
This feedback onto the suprachiasmatic nuclei serves as a feedback mechanism that supports the circadian rhythm. As sleep pressure accumulates during periods of wakefulness, the circadian rhythm system also works to maintain wakefulness.
The circadian rhythm system has an intrinsic cycle, which on average, is just over 24 hours. To compensate for the hour day, the system must undergo phase shifts.
These shifts are driven by time cues called zeitgebers, of which the light-dark cycle is the most effective. The circadian rhythm system works in harmony with the sleep homeostatic system to ensure proper sleep.
Such a complex system that also relies on external stimuli is subject to dysfunction at many levels. Circadian rhythm system disorders can result from intrinsic dysfunction or the result of environmental factors. Six recognized disorders will be discussed below.
The diagnosis of sleeplessness and circadian rhythm disorders is primarily based on a thorough history. A comprehensive history helps in the differentiation of transient disorders from chronic disorders and primary disorders from secondary disorders, which also influences the direction of evaluation and treatment plans.
In cases of sleeplessness, it is essential to distinguish individuals with difficulty initiating sleep from those with trouble maintaining sleep, those with significant daytime impairment, and those with nonrestorative sleep.
The detailed history includes asking questions about the duration of symptoms, a pattern of the sleep-wake cycle, total sleep time, shift work, recent travel, psychological assessment, medication history, self-treatment attempts, environmental cues, and medical problems. The physical examination supplements the history of patients with sleep disorders.
The focus of the physical examination is on identifying risk factors for other conditions that may precipitate, augment, or mimic insomnia, which may include depression, obstructive sleep apnea OSA , and neurodegenerative disease.
The exam evaluates body mass index BMI , craniofacial morphology, chest examination, digital clubbing, and neurologic examination. Delayed Sleep-Wake Phase Disorder [4] [5]. This disorder is characterized by delayed sleep and wake times relative to what is desired or expected.
Not simply "night owls," those with delayed sleep-wake phase disorder may not prefer such a sleep schedule but find it difficult to adjust to desired sleep and wake times. Inadequate sleep and resultant daytime functional impairment are hallmarks of the condition.
Relative to the optimal amount of sleep, on average, those affected lose at least 2 hours of sleep per night. Those affected may have great difficulty waking up and require a significant amount of support to do so.
Sleep inertia may lead to confusion and frustration upon waking. When able weekends, days off , affected patients generally get a sufficient quantity and quality of sleep, but the delayed phase will remain, and patients may sleep well into the day. The incidence of delayed sleep-wake phase disorder peaks in adolescents and is often accompanied by depression.
Some evidence suggests adolescents have longer intrinsic circadian cycles, referred to as tau, that often exceed 24 hours, thus exacerbating the condition.
While most adolescents prefer a later sleep cycle, delayed sleep-wake phase disorder represents a distinct condition detrimental to functioning well beyond the typical adolescent experience. Diagnosis is based primarily on the history of persistent delayed sleep-wake cycles that interfere with desired daytime functioning.
Sleep logs may aid in diagnosis. Other causes of delayed sleep cycles, such as caffeine use and excessive evening light exposure from electronic devices, should be screened.
Treatment consists of behavioral modification, including good sleep hygiene and gradually moving sleep and wake times earlier. With strict adherence to deliberate sleep schedules, most patients can achieve reasonable success in the normalization of sleep schedules. Caffeine, alcohol, nicotine, and daytime naps should be avoided.
Melatonin supplementation and circadian rhythm-light training may also be used if needed. Advanced Sleep-Wake Phase Disorder [6] [7] [8]. This disorder is characterized by excessive evening sleepiness and early morning awakening.
Patients may get adequate quality and quantity of sleep if no external pressures dictate that patients stay awake in the evening, but often patients are distressed and sleep deprived because societal obligations require patients to stay awake longer than desired in the evening.
Patients with advanced sleep-wake phase disorder will wake at the same early time whether they have forced themselves to stay up later, leading to sleep deprivation and daytime sleepiness.
It is hypothesized that advanced sleep-wake phase disorder results from an intrinsic circadian cycle that is less than 24 hours. Advanced sleep-wake phase disorder is more prevalent in older adults and males.
Diagnosis is made with history and sleep logs. Treatment is primarily achieved with evening bright light therapy.
Pharmacotherapy is not indicated for this condition. This disorder represents a failure of the circadian rhythm system to consolidate sleep, leading to multiple short periods of sleep and wakefulness.
Diagnosis is made when no clear circadian rhythm pattern can be identified and at least 3 periods of wakefulness lasting at least one hour occur during an average hour period. This disorder is generally found in patients with dementia and is attributed to dysfunction of the suprachiasmatic nuclei.
Lack of exposure to external time cues zeitgebers may also contribute to this disorder. This may also explain why this condition is more prevalent in older and dementia patients, as they are less likely to have consistent commitments and schedules.
Behavioral modification and melatonin supplementation may help patients establish more consistent circadian rhythms. Jet lag occurs when air travel allows a person to move time zones in a short amount of time, thus causing the intrinsic circadian rhythm to be in desynchrony with external light cues.
This occurs when traveling through at least two time zones. Symptoms include the inability to sleep when desired, daytime sleepiness, and decreased alertness and cognitive performance. Symptoms are usually most prevalent on the day after arrival at a destination.
The intrinsic circadian rhythm will adjust to destination cues at a rate of 1 to 1. Eastward travel is more difficult to adjust to than westward travel. Treatment consists of timed light exposure and melatonin. For longer trips across several time zones, timed light exposure and melatonin can be initiated before travel to start the adjustment process.
Approximately one-third of night shift or swing shift workers meet the criteria for shift work disorder. While some shift workers can adjust easily, others cannot synchronize their circadian rhythm with their sleep debt and schedule demands.
This leads to decreased sleep quality and quantity. While day shift workers have maximum sleep debt and pressure at the end of the day, when their circadian rhythm also promotes sleep, night shift workers often find these 2 drivers of sleep and alertness in conflict with each other. The result is less sleep and lower quality sleep.
Insomnia occurs despite sleep debt when the circadian rhythm promotes alertness and prevents sleep. Conversely, even after sleep, night shift workers often experience sleepiness when circadian rhythms promote sleep during night-time hours. Workers who consistently work the night shift do better than those with rotating schedules.
Of those with rotating schedules, workers tend to do well when shifts are grouped, and the swings progress later in the day instead of earlier.
Treatment consists of first attempting to improve daytime sleep quality and quantity. Sleep hygiene is important, and sleep schedules should be consistent even when not working. A dark, cool, quiet environment is preferred. If the desired amount of sleep cannot be obtained in 1 sitting due to outside constraints, an attempt should be made to obtain at least 3 to 4 hours of "anchor" sleep at the same time every day.
Melatonin and other sleep aids may be of some benefit but may also contribute to residual sleepiness when wakefulness is desired during the subsequent night. Bright light during times of desired wakefulness and light avoidance during and before desired times of sleep may help entrain circadian rhythm to the desired schedule.
Short naps just before or during the shift may improve alertness. Caffeine may improve alertness but should not be used within 8 hours of desired sleep. Non sleep-wake rhythm disorder results from a circadian rhythm system not entrained or running without apparent regulation.
This may result from blindness, where light-dark cues cannot be received but can also occur in those with normal vision. Diagnosis is based on a history of intermittent insomnia and daytime sleepiness alternating with asymptomatic periods when the circadian rhythm happens to fall in line with desired schedules.
Treatment is aimed at entrainment of the circadian rhythm system when able. Tasimelteon is a melatonin-receptor agonist approved for the treatment of non 24 sleep-wake rhythm disorder caused by blindness.
Treatment varies by condition. Please see the specific disease discussions above. Sleeping difficulty is a common complaint encountered in clinical practice. With many causes, the condition is best managed by an interprofessional team that includes a pharmacist, nurse practitioner, neurologist, psychiatrist, primary care provider, psychotherapist, and internist.
Simply prescribing sedatives and hypnotics is not the answer, and healthcare workers address the cause and manage it. Unfortunately, chronic sleep disorders cannot be cured in most cases and often lead to poor quality of life.
