Abnormal brain discharge is a disease in which sudden abnormal discharge of neurons in the brain leads to transient brain dysfunction. The causes mainly include the following: 1. local brain tissue disintegration, resulting in impaired blood supply and changes in extracellular fluid composition of nerve cells; 2. abnormal cell electrophysiology and metabolism, resulting in changes in cell electrophysiology; 3. insufficient blood supply and metabolic disorders in the brain, resulting in overexcitation and thus abnormal discharge; 4. traumatic injuries such as birth injuries and traffic accidents resulting in brain tissue injuries.
