Patient's question:
A few years ago, after working overtime late at night, I suddenly fainted, had convulsions in my limbs, and spat out foam from my mouth. It lasted for about one or two minutes. Afterward, I had no memory of it. Yesterday, after running, it happened again.Doctor's answer:
In clinical medicine, it is believed that the pathogenesis of epilepsy is due to the disintegration of local brain tissue, impaired blood supply, changes in the composition of extracellular fluid, leading to disruption, which causes abnormalities in cellular electrophysiological function, metabolism, and other cellular electrophysiological changes. In the brain, the epileptic focus lacks electrical activity, and the number of neurons is relatively low. Due to insufficient blood supply and metabolic disorders, changes occur, resulting in excessive excitability, leading to abnormal discharging activity. This activity then spreads through surrounding neurons, causing an epileptic seizure. In short, an epileptic seizure is caused by abnormal discharges of brain neurons. The abnormal discharges in the brain lead to hypoxia, causing a series of adverse reactions, such as insufficient blood oxygen content in the brain, inadequate energy supply, and metabolic disorders. If the brain experiences hypoxia, any external stimulation will result in insufficient oxygen levels, leading to repeated episodes of epilepsy.
