The person may also avoid going to sleep for fear of experiencing a parasomnic episode. Treatment Your doctor may first explore whether conditions such as depression or anxiety are causing parasomnias and need to be treated.
If a parasomnia is not related to a mental health condition, treatment might involve behavior modification through hypnosis or relaxation techniques. Prescription tranquilizers may also be appropriate. Prevention is often the best treatment for a parasomnia.
Getting a full night of sleep, keeping a regular sleep schedule and avoiding alcohol before going to bed can help prevent parasomnic events. Illegal drugs as well as prescribed medications, including sleeping pills, can trigger parasomnias in some people. Periodic limb movements are the uncontrollable, repetitive flexing of muscles during sleep.
The movements most often occur in the lower legs, such as a big toe extending or ankle bending repeatedly, as often as several times a minute. An overnight sleep study may be suggested to determine the degree to which the PLMs are present, and to assess how disruptive they are to sleep.
In some cases, the movements do not affect the person experiencing them, but impact the sleep of a person in the same bed. Treatment Periodic limb movements do not always require professional treatment, especially if they do not significantly disrupt sleep.
In cases where treatment is necessary, medication including sleeping pills, anti-seizure medications and narcotic painkillers can often help to either limit the movements, or help you to sleep more continuously through the movements. Restless Leg Syndrome RLS is a neurological condition in which a person has a strong urge to move his or her legs. This urge is often accompanied by unusual sensations in the legs such as itching, burning or prickling.
These sensations usually go away with leg movement. RLS is more common in older people, but it can occur at any age. It is also believed to run in families, as the risk of having RLS more than triples when an immediate family member also suffers from it, according to the American Academy of Sleep Medicine. Treatment For mild cases of RLS, taking a hot bath, massaging your legs or using an ice pack or a heating pad may help alleviate your symptoms.
Lifestyle changes such as regular exercise, quitting smoking and cutting down on alcohol and caffeine can help improve RLS. Some people with RLS also find mental relaxation techniques helpful. A number of prescription medications are available to treat RLS. Usually, their performance declines, with a common example being writing that becomes an illegible scribble during brief sleep attacks. Sleep paralysis is a temporary loss of voluntary muscle control while waking up or falling asleep.
A person remains fully conscious during sleep paralysis, but is unable to speak or move. Periods of sleep paralysis can last for several minutes and, upon waking, people regain the ability to move and speak.
In most people without narcolepsy, REM sleep is reached about 60 to 90 minutes after falling asleep. During REM sleep there is increased brain activity, and vivid dreaming is common. REM sleep also involves a temporary muscle paralysis called atonia. Atonia prevents dreams from being acted out during sleep and normally ends when a person wakes up.
People with narcolepsy enter REM sleep frequently, often within 15 minutes of falling asleep, and experiences normally found in REM sleep may bleed into wakefulness. When atonia persists after a person wakes up, they experience sleep paralysis. Hallucinations can be a frightening experience for people with narcolepsy. These hallucinations most often occur when someone is falling asleep, but can also happen while a person is waking up.
Hallucinations are usually visual, like seeing something or someone in the bedroom, but may also be multimodal, meaning they involve multiple senses, like taste, touch, hearing, or smell.
Hypnagogic hallucinations, those that occur when a person is falling asleep, affect about one-third of people with narcolepsy. Much like sleep paralysis, researchers believe that hallucinations represent REM sleep phenomenon intruding into wakefulness.
Cataplexy involves a sudden loss of muscle tone while a person is awake. Unlike other conditions that involve loss of muscle control, like fainting and seizure disorders, people experiencing cataplexy remain fully conscious.
Cataplexy may be triggered by strong emotions , like laughter, surprise, anger, and excitement. Only people with type 1 narcolepsy experience cataplexy. Sleep paralysis is similar to cataplexy in that it represents a paralysis of muscle activity that normally only occurs during REM sleep. Sleep paralysis occurs on the edges of sleep, but cataplexy occurs after a person is fully awake. Mild episodes of cataplexy may only last a few seconds and involve a small number of muscle groups, such as the eyelids.
More severe episodes of cataplexy may last several minutes and involve a total loss of voluntary muscle control, resulting in complete, but temporary, paralysis. Although these episodes can be frightening, they are typically safe if the person is in an appropriate environment. While doctors have long recognized the classic tetrad of narcolepsy symptoms, recent research suggests that disrupted nighttime sleep is also a common occurrence in people with narcolepsy.
Other sleep disorders seen in people with narcolepsy include insomnia , sleep apnea , REM sleep behavior disorders , and periodic limb movement disorder. Interestingly, despite disrupted sleep patterns, many people with narcolepsy often sleep the same amount of hours as people without this disorder sleep. Rather than having consolidated sleep at night like most people, sleep time in people with narcolepsy often adds up from short periods of sleep throughout the day and the night.
When narcolepsy begins in childhood or adolescence, it often begins with excessive daytime sleepiness. This increased tiredness may result in sleep times that are longer than usual, called hypersomnia, as well as a return to daytime napping typically seen in infants and toddlers. While narcolepsy is a chronic, lifelong condition, symptoms do not typically worsen as a person grows older. Research has demonstrated that patients with narcolepsy are at an increased risk for several medical conditions.
People with narcolepsy face an increased risk of cardiovascular and metabolic conditions such as high blood pressure, high cholesterol, obesity, and diabetes. One reason for the increased prevalence of these conditions in people with narcolepsy may be the multiple roles orexins play in the body. In addition to causing issues in maintaining sleep-wake cycles, a loss of orexin-producing neurons can also affect physical activity and weight gain, nighttime blood pressure, and the buildup of plaque in the arteries — all potential causes of heart disease.
It also helps to drive with a companion who can take over driving if you become drowsy. In addition, keep your mind engaged while driving to stay alert. Listen to music with a fast tempo or play an audiobook or a podcast. This can lead to an accident or injury. Participate in conversations and discussions to remain alert and attentive. If possible, periodically get up from your chair or desk and stretch your legs.
Being physically active can wake up your body and fight sleepiness. If you make lifestyle adjustments but still experience episodes of microsleep or feel sleep-deprived, see a doctor. You may need a sleep study to confirm or rule out a sleep disorder. Understanding the underlying cause of sleep deprivation may prevent future episodes of microsleep. Sleep deprivation is a serious problem because it can impair judgment and reduce your reaction time while driving.
Increasing the quality or quantity of your sleep may provide long-term relief. Another option is consuming about 75 to milligrams of caffeine to increase mental alertness and fight off drowsiness. Keep in mind, however, that caffeine is a stimulant, and having too much over a prolonged timeframe can lead to tolerance. After a long period of too much caffeine use, if you suddenly reduce or stop taking caffeine, you can have unpleasant withdrawal symptoms.
Microsleep can be a dangerous condition, so learn how to identify signs and symptoms of this condition in yourself and others.
