Twitching Before Falling Asleep: What Causes Hypnic Jerks?

Learn something new every day More Info A hypnic jerk is an involuntary spasm or twitch of the muscles that literally jerks a person awake. It usually occurs in the lightest stages of sleep, often just as someone is falling asleep, but not always. The startling spasm also is called a hypnagogic massive jerk, a myoclonic jerkor a sleep start. People often describe it as a falling sensation or an electric shockand it is a common, completely normal experience. Repeated movements that wake a person up during the night are usually caused by a different condition, like restless leg syndrome or periodic movement disorder. This muscle jerk, technically known as a myoclonusmost commonly occurs when a person is sleeping in an uncomfortable position or is overtired. Little research has been done on the subject, but one theory suggests that it may be the result of the muscles relaxing. The body undergoes changes in temperature and breathing as well as a person drifts off to sleep, and the brain could misinterpret this as a sign of falling. Another theory suggests the body reacts to falling asleep much in the way that a person may twitch when dying, and the hypnic jerk is a reflex used to keep the body functioning. When a person hasn't had enough sleep or is trying to not fall asleep, the involuntary spasms may happen more often. Sleep experts theorize that sleep deprivationstress, and fatigue can contribute to the frequency of these movements. Caffeine may also be a factor, because it makes it harder for a person to relax. Some people also report that drinking alcohol makes sleep starts more frequent. To make these spasms less likely, health professionals recommend making sure the bedroom is comfortable and relaxing. People should avoid drinking caffeine or alcohol before bed, and avoid strenuous activities like exercise. If a mattress is old or lumpy, a new one may make a difference.

In some cases, the spasm can affect the auditory nerves as well as the muscles, in a phenomenon known as an auditory sleep start. When this happens, the person hears a very loud snap or cracking sound that seems to come from the center of the head as he or she wakes up. Some people have also experienced visual sleep starts, in which a blinding flash of light awakens the sleeper, but these cases are extremely rare. While some slight twitching and body adjustment is common during sleep, some people experience uncontrolled movements in the rapid eye movement REM phases, which is when most dreaming occurs. During these periods of deep sleep, all voluntary muscle activity usually stops; in rare cases, however, this temporary paralysis is disrupted, and people may move or act out their dreams. This is not a hypnic jerk, although abrupt and violent movements might wake the sleeper. Another condition, called periodic limb movement disorder PLMDcauses a sleeper to experience muscle twitches frequently throughout the night, sometimes as often as every 30 seconds or less.

What is myoclonus? What are the causes of myoclonus? What are the types of myoclonus? What do scientists know about myoclonus? How is myoclonus treated? What research is being done? Where can I get more information? Myoclonus describes a symptom and not a diagnosis of a disease. It refers to sudden, involuntary jerking of a muscle or group of muscles. Myoclonic twitches or jerks usually are caused by sudden muscle contractions, called positive myoclonus, or by muscle relaxation, called negative myoclonus. Myoclonic jerks may occur alone or in sequence, in a pattern or without pattern. They may occur infrequently or many times each minute. Myoclonus sometimes occurs in response to an external event or when a person attempts to make a movement. The twitching cannot be controlled by the person experiencing it. In its simplest form, myoclonus consists of a muscle twitch followed by relaxation. A hiccup is an example of this type of myoclonus. Other familiar examples of myoclonus are the jerks or "sleep starts" that some people experience while drifting off to sleep. These simple forms of myoclonus occur in normal, healthy persons and cause no difficulties. When more widespread, myoclonus may involve persistent, shock-like contractions in a group of muscles. In some cases, myoclonus begins in one region of the body and spreads to muscles in other areas. More severe cases of myoclonus can distort movement and severely limit a person's ability to eat, talk, or walk. These types of myoclonus may indicate an underlying disorder in the brain or nerves. Myoclonus may develop in response to infection, head or spinal cord injury, stroke, brain tumors, kidney or liver failure, lipid storage disease, chemical or drug poisoning, or other disorders. Prolonged oxygen deprivation to the brain, called hypoxia, may result in posthypoxic myoclonus.
