Focal cerebral cortical dysplasia refers to a disorder of cell proliferation or neuronal migration from the cerebral cortex and can be treated with medications and surgery. Focal cerebral cortical dysplasia is a type of cortical developmental malformation and is the most common cause of refractory epilepsy. It is characterized by abnormal neurons and glial cells visible in the localized brain cortex. The etiology of the disease is mainly related to genetics and environment, such as abnormal proliferation, migration defects, and differentiation of adult neuronal cells. Programmed apoptosis is impaired, and there is abnormal synaptogenesis and cortical remodeling. The disease occurs in roughly equal proportions in both sexes and can occur in any part of the brain, with the frontal and temporal lobes being the most common. Typical symptoms are mental retardation and seizures. The disease is mainly treated with antiepileptic drugs such as carbamazepine, stereotactic EEG localization with radiofrequency destruction therapy, and surgical removal of diseased tissue. The effectiveness of treatment varies from person to person. If you are diagnosed with focal cerebral cortical dysplasia, you should seek medical advice and treatment under the guidance of your doctor, and should not take medication without authorization. Pay attention to rest on weekdays, avoid overwork, and actively cooperate with the doctor’s treatment.
