Most epilepsies are not preceded by a seizure, and only a few epilepsies are preceded by some omens, such as abnormal sensation in the limbs, photophobia, sensitivity to noisy sounds, blurred vision, dizziness, and hunger. Most of the epilepsy occurs suddenly, the symptoms are not too obvious in the early stage, and after the onset of epilepsy, the patient can recover quickly, and can be no obvious difference from normal people. Some patients with epilepsy may experience some numbness or small twitching sensations in their limbs a few hours or days before the onset of the disease, and may not even be able to say exactly what kind of abnormal sensation they are experiencing. Some other patients become more sensitive, photophobic, do not want to listen to loud noises, individual patients will have blurred vision, vertigo, hunger and some other aura. For the few patients who have aura of seizure, when the aura appears, you should take measures as soon as possible, timely consultation, under the guidance of the doctor to take anti-epileptic drugs, and make sure that you do not do dangerous work to reduce the stimulation.
