Epilepsy is a clinical syndrome that occurs when highly synchronized abnormal discharges of neurons in the brain are caused by multiple causes. Seizures are often preceded by no aura or a response that occurs over a period of seconds and are generally not related to body position. Seizures can occur during the day and night, often more often during sleep. There are many factors that affect seizures, including fatigue, infection, hunger, alcohol consumption, emotional stress or pregnancy, endocrine disorders, and other abnormalities that can affect the function of neurons in the brain and easily trigger seizures. Seizures are often characterized by impairment of consciousness, abnormal movement, sensory abnormalities, mental abnormalities, and abnormal autonomic functions. What needs to be distinguished from epilepsy are: syncope, pseudoepileptic seizures, episodic sleeping sickness, basilar artery type migraine, transient ischemic attack, hypoglycemia and other similar conditions, which should be clearly diagnosed and distinguished to avoid misdiagnosis and omission to delay the condition and timely examination in regular hospitals. Therefore, there is no fixed time for seizures, which can be during the day or at night when sleeping, but their chance of onset increases when the above-mentioned triggering factors occur, so patients with epilepsy should look for and eradicate the causes and triggers as much as possible.
