Chronic Sleep Disorder: Narcolepsy

Narcolepsy is a sleeping disorder that occurs during the adolescence stage. It is peculiar as it causes the afflicted person to develop a spontaneous sleep cycle during the day. This disorder prompts “sleep attacks” to occur, and can even be accompanied by cataplexy, random muscle failure or really just REM sleep paralysis (Zimbardo, Johnson, Weber,2008, p.109). It can be dangerous as the attacks can be triggered at any time by intense feelings of emotion or a lack of stimulation. This means that in cases such as driving, sexual intercourse, and times of extreme happiness a narcoleptic person could just fall straight into REM sleep (Zimbardo, Johnson, Weber,2008,

Narcolepsy is a chronic neurological disorder caused by the brain's inability to regulate sleep-wake cycles normally. At various times throughout the day, people with narcolepsy experience fleeting urges to sleep. If the urge becomes overwhelming, individuals will fall asleep for periods lasting from a few seconds to several minutes. In rare cases, some people may remain asleep for an hour or longer. In addition to excessive daytime sleepiness (EDS), three other major symptoms frequently characterize narcolepsy: cataplexy, or the sudden loss of voluntary muscle tone; vivid hallucinations during sleep onset or upon awakening; and brief episodes of total paralysis at the beginning or end of sleep. Narcolepsy is not

The symptoms of narcolepsy include cataplexy, persistent daytime sleepiness, sleep paralysis, and hypnagogic hallucinations. Cataplexy is “a loss of skeletal muscle tone without loss of consciousness” (77). These cataplectic attacks often occur at emotional times. Such events could be laughter, sexual intercourse, physical

Narcolepsy is a sleeping disorder that affects 1 in about 2,000 people in the United States. Many people are unaware that they have this disorder, and it goes undiagnosed. Narcolepsy affects your sleeping pattern, including irregular patterns in your Rapid Eye Movement (REM), and significant disruptions in your normal sleep/wake cycle. There is no cure for this disorder, but it is treatable. We also don’t know what causes it.

Firstly, what is narcolepsy? Narcolepsy is a neurological disorder that effects your central nervous system that does not allow the person to have a regulated sleep cycle. A regular person normally has a 90 minute sleep cycle, while a narcoleptic goes straight into REM sleep. Since they go straight into REM sleep, the brain does not have a chance to recover from its constant activities. A narcoleptics

Sleep disorders alter ones sleep pattern and often results in the inability to either sleep or sleep soundly. They often cause you to feel restless, tired, fatigued, and irritable. It is estimated that nearly 75 percent of adult Americans experience sleep disorder symptoms at least a few nights per week. At the same time, sleep disturbances in some form are seen in as many as 25 to 30 percent of infants and children (“Sleep Disorders” 2013). Clearly a huge conundrum in the world, sleep disorders affect an inordinate amount of people. Millions of people suffer or have suffered from a sleep disorder at one point in their lives and if mistreated can impact organ systems functioning negatively. Physical disturbances, medical issues,

Methods: The participants, all males age 23-32, slept in a dark, quiet lab while their brain waves and eye movements were recorded. They were not aloud to sleep at all during the day when they were not in the lab because they might dream. To establish a base for the experiment, participants in the study were allowed to sleep normally for a few nights. The next few nights the participants were fully awaken every time that they started to dream. The next section was the recovery phase where they could sleep normally followed by more nights where they would be woken between

Narcolepsy is a permanent sleep disorder that gets worse with age. It is estimated that about 40,000 to 135,000 people in the United States have narcolepsy. (Narcolepsy, 2002). Most people who have narcolepsy are often times misdiagnosed because the symptoms, especially if noticed at the beginning stages, are very similar to other sleep disorders. Some of the symptoms that go along with narcolepsy are excessive sleepiness, especially during the daytime or when sleep is inappropriate, cataplexy which is when a person suddenly looses control of their muscles, sleep paralysis which is when the person is unable to move for a short period of time after they wake up from sleep, and hypnagogic hallucinations which is very

According to MedlinePlus Medical Encyclopedia, the common symptoms of narcolepsy are periods of extreme drowsiness during the day (MedlinePlus Medical Encyclopedia). People with narcolepsy feel a strong desire to sleep, usually followed by a short nap. The sleep attacks last about fifteen minutes but can be longer. Often times, these sleep attacks happen after eating, during driving, and other everyday tasks. After a short nap, a person usually wakes up feeling refreshed and energized. As stated by Medline Plus Medical Encyclopedia, “Another symptom is dream-like hallucinations between sleep and wakefulness” (MedlinePlus Medical Encyclopedia). This is when a person experiences seeing or hearing right before they fall asleep. Sleep paralysis and cataplexy are also common symptoms of narcolepsy (MedlinePlus Medical Encyclopedia). Sleep paralysis is not being able to move as you are falling asleep or upon waking up. According to the National Institute of Neurological Disorders and Stroke, it usually goes unnoticed because it occurs during REM sleep (NINDS). REM sleep is rapid eye movement sleep. It occurs in breaks when rapid eye movements occur along with bodily movement. Similarly, cataplexy is a sudden loss of mobility. This is also associated with strong emotion like laughter or anger, which can trigger cataplexy

Sleep paralysis is a common condition with a prevalence of 5-62%, although most affected people have single or infrequent episodes (Dahlitz). Occasionally sleep paralysis is found to run in a family, and it can be associated with other disorders of hypersomnia, such as sleep apnea (Becker 81). Narcolepsy has also been linked with sleep paralysis; both are thought to be REM sleep disorders (Siegel). Gender and race do not seem to be a factor of risk for this disorder. The episodes of sleep paralysis seem to range from ages 5-35 (Dahlitz). The use of anxiolytic medicines, psychiatric disorders and high anxiety can also contribute to sleep paralysis (Larkin).

Narcolepsy is a uncommon sleep disorder characterized for excessive daytime sleepiness and significant daily dysfunction. Daily periods of irresistible need to fall asleep during times when individual is supposed to be awake, as driving or at work, that may result in an accident. Patients with narcolepsy must of the times suffer from insomnia caused by sleep fragmentation this is why is imperative for narcolepsy to be diagnosed and treated.

Summary: Narcolepsy and cataplexy are lifelong illness due to the loss of Hypocretin in the brain. Hypocretin is a chemical that regulate sleep cycle, without it people will experience sleep disorder. There is no cure for the disease. However, condition can be managed by drug therapy and several behavioral strategies. But I am looking forward that one day researcher will find a cure for it so I can live my life normally as I used before.

A person with narcolepsy can experience extreme daytime sleepiness and uncontrollable falling asleep during daytime.

Sleepwalking occurs during stages 3 and 4 of the sleep cycle, the deepest levels of sleep. This slow-wave sleep is normally characterized by synchronized EEG activity (4). This indicates that mental activity is very low during these stages of sleep. However researchers have shown that the EEG of a sleepwalker has diffuse, rhythmic, high-voltage bursts of delta activity associated with abrupt motor activity (1). This is very different from the EEG activity normally associated with slow-wave sleep. In addition to the EEG results, they found that there is a decrease in regional cerebral blood flow in the frontopariental cortices during sleepwalking (1). This indicates that sleepwalking is a dissociated state consisting of motor arousal and persisting mind sleep, which seems to arise from the selective activation of thalamocingulate circuits and the persisting inhibition of other thalamocortical arousal systems (3).

The EEG recordings where collected with the Quickcap using twenty-six electrodes located to the 10-20 system. The data was recorded at sample rates
