One of the most obvious sequelae of epilepsy is mainly mental retardation, which is one of the main sequelae of epilepsy, especially in some children with epilepsy. The intelligence of children with epilepsy is far lower than that of normal children, which is considered to be due to the repeated epileptic seizures affecting the neurological function of the brain, leading to mental retardation in the children. Some adults with recurrent epileptic seizures, resulting in ischemia, hypoxia, and necrosis of brain cells, can also suffer from memory loss, slow response, and slow reaction time. Sequelae of epilepsy can also appear epileptic encephalopathy, such as prolonged or repeated epileptic seizures, resulting in ischemia, hypoxia, edema, necrosis of brain tissues, and the patient can experience irreversible damage to brain tissues, which manifests itself in some symptoms of neurological deficits, such as unfavorable limb movement, problems with muscle tone, and so on. The sequelae of epilepsy can also be manifested as inattention, temper, mental and psychological defects, etc. For epilepsy, it is necessary to take regular oral epilepsy-control medications under the guidance of a physician to avoid recurrent epileptic seizures.
