Pitolisant is a new agent for treating the excessive daytime sleepiness of narcolepsy that also helps cataplexy control by increasing histamine concentrations in the hypothalamus.

Sodium oxybate is probably the most effective drug for severe cataplexy, taken before overnight sleep and once through the night its precise mechanism of action remains obscure. Antidepressant drug therapy at relatively low doses is the traditional treatment these most likely work through inhibiting REM sleep, predominantly by increasing brain monoamine concentrations. Cataplexy can be the most disabling symptom of the narcolepsy syndrome, severely limiting normal activities of daily living. A defining and enigmatic aspect is that certain emotional stimuli usually trigger the episodes. The semiology of cataplexy differs between adults and children. Cataplexy reflects the dysregulation of rapid-eye-movement (REM) sleep, such that REM-sleep atonia intrudes inappropriately into wakefulness as brief episodes of either focal or total paralysis of voluntary muscle. ➡️ Type 2 narcolepsy patients, on the other hand, have normal brain levels of hypocretin and usually don’t experience cataplexy.Remarkably and almost invariably, the clinical phenomenon of cataplexy results from the loss of around 40 000 hypocretin-containing neurones in the lateral hypothalamus in the context of narcolepsy type 1. Type 1 patients also experience sudden weakness or loss of muscle tone, which is known as cataplexy. Its triggered by emotions, like anger or laughter. ➡️ Type 1 narcolepsy is more common and is associated with low levels of a brain chemical called hypocretin, which helps regulates a person’s sleep-wake cycles, according to the National Institute of Neurological Disorders and Stroke (NINDS). She explains that cataplexy involves the sudden, uncontrollable loss of muscle function. To understand these symptoms, it’s helpful to know that narcolepsy symptoms can differ between adults and kids, and that the disorder comes in two types:

40 In the vast majority of attacks, cataplexy affects muscle groups bilaterally, although patients sometimes report one side of the body to be more involved than the other.

All patients who have narcolepsy experience EDS, though not all fall asleep without warning.Īlong with EDS, there are more subtle signs of narcolepsy-symptoms that typically don’t make it into movies or TV shows, and vary from patient to patient. It most often results in buckling of the knees, head dropping, sagging of the jaw, slurred speech or weakness in the arms ( Fig. But the disease’s hallmark symptom is actually excessive daytime sleepiness (EDS), which the National Heart, Lung, and Blood Institute describes as “an overwhelming sense of sleepiness” that comes on quickly. Narcolepsy is a rare long-term brain disorder that causes a person to suddenly fall asleep at inappropriate times. It’s true that many people with narcolepsy fall asleep suddenly. In children, cataplexy can primarily affect the face and may look slightly different for example, grimacing, mouth opening, or a tongue thrusting.

And it's easy to understand why: That’s how the condition is often depicted in movies and on TV. When you hear the word “ narcolepsy,” you probably think of someone falling asleep without warning.
