fcd is the English abbreviation for focal cerebral cortical dysplasia, most of which can be cured by surgical removal of the epileptogenic foci and discharging areas, and can obtain more satisfactory surgical results, but it needs to be based on its own situation, and cannot be generalized. Focal cerebral cortical dysplasia, a disorder of focal cerebral cortical structural abnormalities and cellular abnormalities mainly involving the cerebral cortex, is a common cerebral cortical developmental disorder and an important cause of intractable epilepsy, with localized thickening of the cortex, the cerebral gyrus becoming narrower and smaller than the contralateral side, the grey and white matter boundaries becoming indistinct, the white matter decreasing, and the sulcus becoming deeper and wider. The location of dysplasia can be localized through nuclear magnetic examination, and the scope of epileptic foci can be clarified through EEG and other examinations. Surgical resection can be relied upon to remove the lesion, and if the lesion is located in a not very important location, surgical resection can be cured. It is recommended to go to the hospital in time, under the guidance of the doctor, early detection, early treatment, in order to prevent delays.
