Lele, who lives in the south, is 23 years old, and since he was 3 years old, the most familiar place in his memory is the hospital. 20 years ago, he was hospitalized in the local hospital for a week due to high fever, and was diagnosed with “encephalitis B”, since then, he often had episodes of limb convulsions with loss of consciousness, blue lips, foaming at the mouth, closed teeth, and occasional The family was worried about the situation. What worries his family is that as the days go by, Lele is often alienated by his classmates when he goes to school, bringing many shadows to his young mind. In recent years, Le’s parents took him to many hospitals, where he was diagnosed with “epilepsy” and given a variety of anti-epileptic drugs, but his symptoms never improved significantly. In order to seek further treatment, his family took him to Tangdu Hospital of the Fourth Military Medical University in Xi’an. The outpatient video EEG showed abnormal discharges in the right temporal region, and a small number of epileptic waves were seen in the right frontal-occipital region. After the head MRI showed sclerosis of the right hippocampus, he was admitted with the diagnosis of epilepsy (partial seizure followed by generalized tonic clonic seizure) and sclerosis of the right hippocampus. On the second day of admission, Director Zhang Hua checked the room, and based on the consistent localization of the lesion on imaging and EEG, the diagnosis was clear and the indications for surgery were clear. The intraoperative procedure went smoothly. At the postoperative checkup, Lele was in good spirits, eating and sleeping well, and had no more headaches, and his 20-year epilepsy symptoms were effectively controlled. When he was discharged from the hospital, Lele and his family were very grateful to our neurosurgeon. The disease is mainly transmitted by mosquitoes and is seen in summer and autumn. It has an acute onset with high fever, impaired consciousness, convulsions, tonic spasms and meningeal irritation. According to Prof. Zhang Hua of the Epilepsy Center of Tangdu Hospital, the patient has a long duration of illness, and the history is characterized by seizures, transient and recurrent. According to the symptoms of his seizures, attention must be paid to the differential diagnosis as follows: 1. Pseudoseizures: the patient is often a large child and adult, both have psychiatric factors, the seizure form is very diverse, accompanied by strange and unusual behavior, no tongue biting, no incontinence, no seizure-induced No tongue biting, no urinary incontinence, no trauma caused by seizures. EEG is normal. 2. Vascular syncope: emotional excitement, fear, pain, bleeding, fatigue, sultry weather, and prolonged standing are common triggers, manifesting as dizziness, pallor, confusion, and even loss of consciousness, which may be accompanied by urinary incontinence, and sometimes tonic spasms, mostly occurring in the upright or standing position, accompanied by pallor and profuse sweating; there is no headache and no feeling of weakness during the attack. EEG is normal. 3. Sleep disorders: usually less than 10 years old, the number of seizures gradually decreases over time, each seizure is about 15 seconds to 30 minutes, seizures are not stereotyped, seizures are mostly in the first 1/3 of the night, high amplitude slow waves are visible on EEG during seizures. 4. Hypoglycemia: Such patients have more than a short period of lethargy, weakness, hunger, sweating and other prodromal symptoms before the occurrence of convulsions, and their blood sugar is lower than 2.8-3.4 mmol/l. The symptoms disappear or reduce soon after taking sugar. 5. Disorientation seizure: The patient shows a brief interruption of consciousness, suddenly stopping the action in the hands, waking up immediately afterwards and continuing the original activity, usually lasting 3-15 seconds, rarely more than 45 seconds, and showing a characteristic 3-Hz spike or spike wave on the EEG. 6. Partial epilepsy: Patients exhibit simple motor seizures or sensory seizures, etc., manifesting as twitching or sensory numbness of one limb, or only impaired consciousness without tonic twitching of the limbs, while the EEG is seen to have originated from one side.
