Sleep epilepsy refers to abnormal discharges in the sleep state cerebral cortex that manifest as seizures. Symptoms are usually atypical, and the most common manifestations are sudden awakening from sleep, sudden seizures, brief (shorter than 2 minutes), multiple seizures characterized by automatism, and also generalized seizures. The vast majority of seizures occur during sleep, including long sleeps at night and daytime naps, and occasionally after waking.1. A generalized seizure is manifested by the patient suddenly waking up during sleep or having blinking movements, generalized convulsions, calling out, foaming at the mouth, eye rolling up or eye gazing; 2. A partial seizure is manifested by twitching of one limb, clonus, simple orofacial twitching; 3. A few patients may also experience panic attacks, seizure nausea, vomiting, and even aggressive behavior during sleep, resulting in decreased sleep quality. Sleep epilepsy can be observed first if there is no continuous status epilepticus, one seizure occasionally and for a short period of time without too much pain. If the seizures are prolonged, the symptoms are more complex or other problems arise, you should seek prompt medical attention.
