Narcolepsy

Narcolepsy is a chronic sleep disorder characterized by excessive daytime sleepiness (EDS) and irregular rapid eye movements (REM) sleep taking place daily for a period of 3 months. During the onset of these symptoms, one may experience extreme tiredness, compelling the individual to fall asleep during the day at inappropriate times, such as at work or school. A narcoleptic patient frequently experience disturbed nighttime sleep, which is often confused with insomnia, and sometimes, cases of hypersomnia are misdiagnosed as this condition. Cataplexy or sudden muscular weakness brought on by strong emotions is a medical condition is another symptom that most narcoleptics demonstrate. The manifestations of muscular weakness range from scarcely discernible loosening of the facial muscles to dropping of the jaw or head, shabbiness at the knees, or a total collapse. Frequently, speech is inaudible; vision is impaired; with occurrences of double vision and inability to focus the eyes onto an object and conversely, hearing abilities and awareness remain normal. In some atypical instances, an individual's body becomes paralyzed and muscles will become stiff which may bring about total collapse.

Kleine-Levin Syndrome

KLS is a rare neurological disorder characterized by recurrent periods of prolonged sleep with intervening periods of normal sleep and alert awakening. People with Kleine-Levin syndrome have symptoms that differ from the symptoms of other forms of hypersomnia. Patients sleep for 18 or more hours a day and often are irritable, uninhibited, and make indiscriminate sexual advances. They also develop an uncontrollable appetite and thus rapidly gain weight. Upon onset of an episode the patient becomes drowsy and sleeps for most of the day and night, such condition is referred to as hypersomnolence. They only rouse from sleep to eat or go to the bathroom. It is described that the patient’s demeanor changes or seem different during the times that they are awake. They often appear “spacey”, “lost” or “childlike”. They also experience confusion, disorientation, lethargy or complete lack of energy, and apathy or lack of emotions. These individuals eventually lose their social function as they are not able to attend school, work, or care for themselves. Most become bedridden and uncommunicative even when awake.

Kleine-Levin syndrome patients may be asymptomatic, meaning they may go for a period of weeks, months or even years without experiencing any symptoms, and then they reappear with little warning. The cause of Kleine-Levin Syndrome is still undetermined, although many studies had been conducted to discover its cause. For that fact, there are no concrete treatments for this condition and thus, family support and education are the best management currently available. 9
