Epilepsy is a chronic brain disorder in which sudden hyper-synchronous abnormal discharges of neurons in the brain cause transient brain dysfunction. It is characterized by sudden and transient symptoms, with a variety of manifestations due to the location of the abnormally discharged neurons in the brain; in other words, there are as many seizure symptoms as there are functions in the brain. The common symptoms of epilepsy are briefly described as follows: 1. Generalized tonic-clonic seizures (also known as grand mal seizures): sudden loss of consciousness followed by tonic and then clonic spasms, often accompanied by screaming, cyanosis, urinary incontinence, tongue bite, foaming at the mouth or blood froth, pupils dilated for tens of seconds or minutes after the clonic seizure relieves itself and enters a drowsy state. Recollection of the seizure process. 2. Aphasic seizures (also called petit mal seizures): sudden interruption of mental activity, loss of consciousness, one seizure for a few seconds to more than ten seconds, dozens of seizures per day, EEG appears 3 times/second spikes or spikes and slow integrated waves. 3. Simple partial seizures: Tonic clonic seizures or abnormal sensory seizures in one part or one limb, which last for a short period of time and are clearly conscious, are called Jackson seizures if the seizures extend to other limbs or the whole body along the motor area. After the seizure, there may be temporary paralysis of the affected limb called palsy, also known as Todd’s palsy. 4, complex partial seizures (also known as psychomotor seizures): can be manifested as motor, sensory or psychogenic partial seizures, accompanied by varying degrees of impaired consciousness. It can also manifest as autonomic manifestations such as neurosis and nocturnal sleepiness.
