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 much lower than that of normal children, and is considered to be due to recurrent seizures that affect the neurological function of the brain, resulting in low intelligence in the affected children. Some adults with recurrent seizures, which result in ischemia, hypoxia, and necrosis of brain cells, can also experience memory loss, slow reactions, and unresponsiveness. Seizure sequelae can also occur in epileptic encephalopathy, such as long-term or recurrent seizures, resulting in ischemia, hypoxia, edema, and necrosis of brain tissue. Patients can develop irreversible damage to brain tissue, which manifests as some symptoms of neurological deficits, such as unfavorable limb movement and muscle tone problems. The sequelae of epilepsy can also be manifested as inattention, temperament, and psychosomatic defects. For epilepsy, regular oral seizure control drugs should be taken under the guidance of physicians to avoid recurrent seizures.
