What causes convulsions during sleep?
Nocturnal convulsions during sleep, no discomfort during the day, occasional chest tightness, and an urge to shout loudly—this situation has persisted for a week. Doctor, what causes convulsions during sleep?
Convulsions during sleep, medically referred to as "nocturnal myoclonus" or "hypnic jerks," are primarily caused by the following factors:
I. Non-disease Factors
1. Excessive fatigue: After strenuous exercise during the day or before bedtime, the body may experience muscle twitching during sleep due to overexertion.
2. Calcium deficiency: Insufficient calcium levels in the bloodstream can increase neuromuscular excitability, leading to convulsions at night, especially in the legs.
3. Excessive emotional excitement: Significant stress, excessive thinking before bedtime, or intense emotional fluctuations may cause involuntary body movements.
4. Muscle tension before sleep: Muscle tension caused by exercise or other factors prior to sleep may also trigger twitching when the muscles begin to relax after falling asleep.
II. Disease-related Factors
1. Restless Legs Syndrome: This is a neurological disorder characterized by uncomfortable sensations such as crawling or creeping feelings in the deep leg muscles, which can lead to involuntary repetitive and stereotypical movements.
2. Brain disorders: Conditions such as brain tumors, acute brain infections, and subarachnoid hemorrhage may also cause convulsions during sleep.
3. Other medical conditions: Hypocalcemia, hypomagnesemia, periodic limb movement disorder, and similar conditions may also lead to sleep-related convulsions.
Occasional hypnic jerks typically do not require special treatment. However, if they occur frequently, disrupt sleep quality, or are accompanied by other symptoms such as pain, medical evaluation is recommended.
