Patient's question:
My sister has been feeling very unwell recently. She has been dizzy, having poor appetite, and weak limbs. Yesterday, she suddenly fainted and had convulsions with foam coming out of her mouth. She is very scared.Doctor's answer:
Hello, under normal circumstances, the developed neurons in the brain have a certain self-stabilizing function, with their excitatory and inhibitory systems in a relatively balanced state. Many brain or systemic diseases disrupt this balance, leading to a decrease in the excitatory threshold of neurons and excessive synchronous discharge, thereby causing convulsions.
