Hypnagogic spasm

Hypnagogic seizure: understanding, causes and treatment

A hypnagogic cramp, also known as a sleep cramp, is an unpleasant phenomenon that can occur in some people during the transition between wakefulness and sleep. This phenomenon gets its name from the Greek words “hypnos” (sleep) and “agogos” (leading, causing), since it manifests itself precisely during falling asleep.

Symptoms of a hypnagogic spasm can vary, but usually include a feeling of sudden muscle contraction, accompanied by a sensation of falling, electrical shocks, or even visions. People suffering from this condition may experience instant awakening and a feeling of helplessness in the face of these involuntary spasms. Although hypnagogic seizures can be frightening, they are usually not a health threat and usually do not require special treatment.

The causes of hypnagogic seizures are not entirely clear, but scientists suggest that they are associated with the transition of the brain from wakefulness to sleep. During this transition phase, certain parts of the brain may become out of sync, leading to seizures. It is also believed that stress, lack of sleep, poor daily routine and the use of certain medications can contribute to the occurrence of hypnagogic seizures.

Although hypnagogic seizures usually do not require treatment, in some cases your doctor may recommend measures to improve sleep and reduce the possibility of seizures. Here are some tips that may help:

  1. Regular sleep: Aim to sleep at the same time every day to establish a regular sleep cycle. Lack of sleep can increase the likelihood of hypnagogic seizures.

  2. Avoid stress: Regularly practice relaxation techniques such as yoga or meditation to reduce stress and improve sleep quality.

  3. Create a comfortable sleep environment: Provide a quiet, cool and dark bedroom environment that promotes restful sleep.

  4. Avoid stimulants: Limit your intake of caffeine and alcohol, especially close to bedtime, as they can negatively impact sleep quality and contribute to cramping.

  5. Contact your doctor: If hypnagogic seizures become frequent, severe, or interfere with normal sleep, you should contact your doctor. Your doctor can evaluate you and recommend individual treatments or symptom management if needed.

In conclusion, hypnagogic seizures are a relatively common phenomenon that may occur in some people during the transition between wakefulness and sleep. Although it usually does not require specific treatment, regular sleep, stress management, and a comfortable sleeping environment can help reduce the possibility of cramps. If symptoms become problematic, it is important to see your doctor for advice and recommendations.



Convulsive (hypnagogic) is a sudden disruption of muscle function, which can occur due to sudden relaxation. The process occurs during immersion in sleep - exit from reality into a night dream. It is believed that jerky movements and muscle contractions occur due to chemical changes in the brain. Muscle contractions can lead to various ailments and even be a sign of fatal diseases.

How does convulsive illness manifest?

Convulsive movements accompany falling asleep and the beginning of night sleep. The cramps are replaced by severe weakness and a feeling of excruciating pain. During an attack, the muscles tense and are unable to relax. Each spasm usually lasts a short period of time and is repeated several times. Most often, attacks occur in different parts of the body, but the most intense are muscle spasms of the limbs.

In a patient, a convulsive state may manifest itself as attacks of back pain, difficulty breathing due to spasm of the diaphragm, contractile movements of the tongue, as well as damage to the facial muscles. Before the onset of an attack, the patient develops irritability, nausea, and muscle weakness.

Spontaneous muscle contractions that appear under the influence of external factors are called ketamic. Their occurrence is common and is directly related to the manifestation of convulsive syndrome. Often such movements occur when watching films with scenes of murder or contact with dangerous people. This is due to the operation of chemically active areas. They are necessary to increase psychological activity.
