Narcolepsy The American Sleep Foundation estimates the number of Americans with narcolepsy at between 125,000 and 200,000, but also notes that less than 50,000 of those people have received an accurate diagnosis, because narcolepsy is often confused with mental or emotional problems, or with seizure disorders.

seizure disorder There are more than 20 different seizure disorders. One in ten Americans will have a seizure at some time, and at least 200,000 have at least one seizure a month. Epilepsy affects 1-2% of the population of the United States. Although epilepsy is as common in adults over 60 as in children under 10, 25% of all cases develop before the age of five. One in every two cases develops before the age of 25.

Epilepsy and Seizures It is one of the most common disorders of the nervous system and affects people of all ages, races, and ethnic background. Almost 2.2 million Americans live with epilepsy. Anything that interrupts the normal connections between nerve cells in the brain can cause a seizure.

Narcolepsy Narcolepsy is a disorder that causes sudden episodes of deep sleep. These episodes can occur often and at inappropriate times, for example while a person is talking, eating or driving. Although sleep episodes can happen at any time, they may be more frequent during periods of inactivity or monotonous, repetitive activity.

- Seizures are very common: Researchers believe that about 5 percent of people in the United States experience at least one seizure. Seizures are more common in children than in adults, and infants and young children are affected especially often. Epilepsy is a condition in which a person is more susceptible to having unprovoked seizures. A child may have epilepsy if she has had two or more unprovoked seizures.

Overview In narcolepsy, however, you may suddenly enter into REM sleep without first experiencing NREM sleep, both at night and during the day. Some of the characteristics of REM sleep, such as cataplexy, sleep paralysis and hallucinations, occur during wakefulness or drowsiness in people with narcolepsy. 1  Symptoms. 2  Complications.

Narcolepsy: Causes, symptoms and treatments In most cases, excessive daytime sleepiness is the first sign of narcolepsy. This can have a significant impact on everyday life. Excessive daytime sleepiness (EDS) is a persistent background feeling of sleepiness with a tendency to doze off at intervals throughout the day, often at inappropriate times (sleep attacks).

Sleep-Wake Disorders 125,000 Americans are estimated to have narcolepsy. It strikes males and females and all races. Symptoms most commonly appear in a person's teens and early twenties. The disease can vary in severity. Some persons with it have mild sleepiness or rare cataplexy (less than one episode per week). Other persons may have moderate sleepiness or infrequent cataplexy (less than one episode a day).

Narcolepsy In 1999 researchers identified the gene that causes the disorder. The narcolepsy gene allows cells in the hypothalamus (the part of the brain that regulates sleep behavior) to receive messages from other cells. As a result of the mutation, the cells cannot communicate properly, and abnormal sleeping patterns develop.

Symptoms of Narcolepsy 1 EDS is the primary symptom of narcolepsyand must be present for at least 3 months in all patients. 2  Cataplexy is a brief and sudden loss of muscle tone and represents REM intrusion during wakefulness. 3  Sleep paralysis is the inability to move upon awakening or less commonly upon falling asleep with consciousness intact.

Narcolepsy In a typical sleep cycle, we initially enter the early stages of sleep followed by deeper sleep stages and ultimately (after about 90 minutes) rapid eye movement (REM) sleep. For people suffering from narcolepsy, REM sleep occurs almost immediately in the sleep cycle, as well as periodically during the waking hours.It is in REM sleep that we can experience dreams and muscle paralysis -- which explains some of the symptoms of narcolepsy.lthough there is no cure for narcolepsy, the most disabling symptoms of the disorder (EDS and symptoms of abnormal REM sleep, such as cataplexy) can be controlled in most people with drug treatment.

- Narcolepsy is a chronic brain disorder that involves poor control of sleep-wake cycles. People with narcolepsy experience periods of extreme daytime sleepiness and sudden, irresistible bouts of sleep that can strike at any time. These “sleep attacks” usually last a few seconds to several minutes. Narcolepsy can greatly affect daily activities.

Narcolepsy There are a number of symptoms that are associated with narcolepsy. Most begin between the ages of 10 and 25, but they can begin at anytime up until a person enters their 50s. Symptoms of narcolepsy are often more severe when they begin early in life.

Narcolepsy Another common feature of narcolepsy is cataplexy, which is a sudden loss of muscle tone in response to strong emotion (such as laughing, surprise, or anger). These episodes of muscle weakness can cause an affected person to slump over or fall, which occasionally leads to injury.

What Causes Narcolepsy? What Causes Narcolepsy? Narcolepsy with cataplexy is caused by a lack of the chemical hypocretin in the brain. Hypocretin is an important chemical for regulating wakefulness and rapid eye movement (REM) sleep. Narcolepsy without cataplexy includes most of the same symptoms, but its cause is unknown. Injuries to the hypothalamus and brain stem, tumors, and stroke are under investigation.
