ObjectiveThis study aimed to explore the timing of the long-term antiepileptic drugs (AEDs) therapy in patients with stroke related seizures. MethodsWe enrolled 90 Patients with post-stroke seizures who diagnosed in neurology and epilepsy specialist clinic of Tianjin Medical University General Hospital and followed up for at least 12 months from September 2014 to August 2016. The patients were divided into early-onset seizure group (occurring within 2 weeks of stroke) and late-onset seizure group (occurring after 2 weeks of stroke).The two groups were subdivided into treated and untreated group after the first seizure. ResultsThe patients were followed up for 12~96m (median 20m). 31 patients in ES group, 19 of which in treated group and 12 of which in untreated group. 59 patients in LS group, 36 of which in treated group and 23 of cases in untreated group. The recurrence rate of second seizures occurred in each group and the comparison between the subgroups in the 3rd, 6th, 9th and 12th mouth of follow-up as follows. 1 LS group compared with the group of ES, the recurrence rate of second seizures was high (25.81%~38.71% vs. 49.15%~69.49%), and there was statistical difference (P < 0.05). 2 The recurrence rate of ES in untreated group was lower than that in untreated LS group (16.77% 33.33% vs. 56.52% 73.91%), but only in 3m and 12m the difference was statistically significant (P < 0.05). 3 There was on statistically significant different in ES treated group compared to untreated group, LS treated group compared to untreated group, ES treated group compared to LS treated group (P > 0.05). Both in group of ES and LS, The ratio of seizure recurred patients at different time points during follow-up period was highest at the time of 3m, 3 6m followed, within six months respectively as high as 91.67% and 76.59%. ConclusionOnly one early-onset seizure after stroke can be suspended long-term AEDs treatment, once it recurred that indicates the need for treatment. However, the recurrence rate of late-onset seizure was higher than that of early-onset seizure and it should be given long term AEDs treatment after the first seizure.
ObjectiveTo explore the clinical and video EEG features of patients with post-stroke epilepsy (PSE).MethodsThe clinical data of 68 patients with epilepsy after cerebral infarction and 33 patients with epilepsy after cerebral hemorrhage were analyzed retrospectively from January 2015 to June 2018 in the Affilated Hospital of Jining Medical University. There were 5 cases of early-onset epilepsy, and the rest were late-onset epilepsy. There were 68 cases of cerebral infarction (1 case showed post-infarction hemorrhagic transformation), 33 cases of cerebral hemorrhage; 51 females, 50 males (f∶m = 1.02∶1); the onset age was 45 ~ 101 years, with an average of (68.10 ± 10.26) years.ResultsThe time from seizure to stroke in 101 cases was (28.92 ± 35.61) months, 60 cases (59.40%) ≤ 1 year, 26 cases (25.74%) 1 ~ 5 years, and 15 cases (14.85%) 5 ~ 10 years. Post-stroke epilepsy had no relation to gender (P>0.05). The age of onset is mostly in 60 to 75 years old (62.38%). Seizure often happen within 1 year after stroke (59.4%). The type of attack is focal seizure (77.23%). Cortical infarction (77.94%), cerebral artery stenosis (83.82%), hypertension, diabetes, and atrial fibrillation are risk factors for epilepsy after infarction. The abnormal rate of EEG for PSE is 90.1%, which was manifested as slow wave in the lesion side, epileptic wave in the lesion side or contralateral side.ConclusionsThe location, duration, age and severity of cerebral artery stenosis in patients with PSE are closely related to the occurrence of seizure. VEEG plays an important role in the diagnosis, treatment and prognosis of epilepsy.
Homocysteine is an intermediate product of methionine and cysteine metabolism, and plays a key role in methylation. Epilepsy is one of the common diseases of the nervous system, long-term repeated seizures will not only cause damage to the brain tissue, but also cause cognitive impairment. At present, the clinical treatment for epilepsy is still mainly to control symptoms, the fundamental etiology of epilepsy still needs to be improved, to explore the etiology of seizures, fundamentally control seizures, is still our long-term struggle direction. High homocysteine is associated with many diseases. Epidemiological studies have shown that the serum homocysteine level of 10% ~ 40% of epilepsy patients is higher than that of the normal population. By exploring the relationship between serum Hcy and epilepsy,We expect to provide help for the diagnosis and treatment of clinical epilepsy.
