  • Mutiple factors analusis of the influence of epilepsy onset age on the patients with tuberous sclerosis complex

    ObjectiveTo investigate the relationships between the onset age, genotype, clinical phenotype and the efficacy of Rapamycin in patients with tuberous sclerosis complex.MethodsRetrospectively analyze the clinical data of patients with tuberous sclerosis complex (TSC) who were diagnosed with epilepsy in Guangdong Sanjiu Brain Hospital from October 2013 to December 2018. Meanwhile, the relationships between the onset age of epilepsy and genotype, clinical phenotype and Rapamycin efficacy were analyzed comprehensively.ResultsTSC gene was detected in 104 patients with tuberous sclerosis complex, of which 85 (81.7%) were positive and 44 (51.8%) were males as well as 41 (48.2%) were females, with an average age of (4.0±4.9) years old. And there were 34 (40.0%) TSC1 mutations and 51 (60.0%) TSC2 mutations. The patients were divided into 3 groups according to their ages: ≤1 year old, 1 ~ 6 years old and ≥6 years old. Among them, 31 cases (36.5%) were in the ≤1 year old group, 31 cases (36.5%) in the 1 ~ 6 years old group and 23 cases (27.0%) in the ≥6 years old group. Through statistical analysis, we found that the onset age of epilepsy in patients with TSC1 and TSC2 gene mutations was statistically different (χ2=9.030, P=0.011). Further analysis of the relationship between the onset age of epilepsy and other clinical phenotypes showed that there were statistical differences in the probability of mental retardation and spasm seizure in different onset age groups of epilepsy (P<0.05). In addition, patients with epilepsy onset age ≤1 year old are more likely to have renal disease and patients with epilepsy onset age ≥6 years old are more likely to have SEGAs. There was no significant difference between the onset age of epilepsy and the efficacy of Rapamycin (P>0.05).ConclusionTSC2 mutation, mental retardation and spasm seizure are more likely to occur in patients with epilepsy onset age ≤1 year old. The study on multiple factors of epilepsy onset age may have a certain guiding role in judging the development and prognosis of TSC with epilepsy.

  • Application of fMRI in combination with Wada test in preoperative assessment of speech function in medically refractory epilepsy

    Objective To investigate the task group’s effectiveness in language evaluation based on the task group's functional Magnetic resonance (fMRI) results’ agreement with the fixation side of the Wada language area. MethodsWe collected 90 patients with intractable epilepsy of 90 patients from December 13, 2018 to January 3, 2020 from the Epilepsy Center of Guangdong 999 Brain Hospital. We used two simple fMRI tasks. Among them, 25 patients completed the Wada experimental examination, and 8 patients completed the electrode implantation and subsequent preoperative language area mapping. Adopt block experimental design, ABBA style presentation, and use AFNI software to process fMRI data, lateralization index calculation, and multiple regression analysis. ResultsfMRI results from 90 patients showed that the results from both the sentence-completion task and the image-naming task were more stable than those from either task. The results were then compared with the results of the “gold standard” Wada test in 25 patients with fMRI-located language dominance in the hemisphere. The results showed that the accuracy of the single task was between 70% and 80%, but the accuracy of the combined results of the two tasks was 93.3%. Conclusions Compared with the results of a single task, the results of multiple fMRI tasks are more stable in the judgment of activation range and language dominance hemisphere. fMRI and Wada language area siding accuracy 93.3%, fMRI task siding valid and replicable.
