- Brief Summary
This study aims to observe the effect and safety of cerebellar continuous θ burst stimulation (cTBS) for drug-refractory epilepsy(DRE), in order to provide a new treatment for DRE and improve the quality of life of those patients. A total of 44 patients with DRE will have cTBS via accurate navigation to bilateral cerebellar dentate nuclei. Patients will be randomised into 2 groups in a crossover trial design to have 2 week periods of cTBS separated by 8 week washout periods, following which the patient will cross over to have the opposite condition for a further 2 week. Frequency and symptoms of seizures, scalp EEG, clinical scores, and QOLIE-31 were assessed at baseline and after 1 and 2 month of treatment.

Group Intervention Description cTBS First cTBS First The first stage, participants received cTBS treatment for a total of 10 times during two weeks, then followed up for eight weeks; the second stage, participants are treated with pseudo-stimulation for a total of 10 times during two weeks, then followed up for 8 weeks similarly. Pseudo-stimulation First Pseudo-stimulation First The first stage, participants received pseudo-stimulation treatment for a total of 10 times during two weeks, then followed up for eight weeks; the second stage, participants are treated with cTBS for a total of 10 times during two weeks, then followed up for 8 weeks similarly.
- Primary Outcome Measures
Name Time Method responder rate 8 weeks proportion of people with a 50% or greater reduction in seizure frequency following the treatment period
seizure reduction rate in pre- and post-treatment 8 weeks A 28-day baseline for seizure frequency will be recorded by the patients themselves or their relatives before therapy and then compare to the frequency at 4-week and 8-week after treatment, finally, the rate of reduction in seizure frequency was obtained
- Secondary Outcome Measures
Name Time Method IQ 8 weeks Wechsler Abbreviated Scale of Intelligence. Above 130 points very excellent, 120-129 excellent, 110-119 above average, 90-109 average, 80-89 below average, 70-79 critical level, below 69 mental retardation, 50-69 mild mental retardation, 35-49 moderate mental retardation, 20-34 severe mental retardation, less than 20 extremely severe mental retardation.
MoCA 8 weeks Montreal Cognitive Assessment. A max score is 30 points, and a score ≥ 26 is considered normal.
MMSE 8 weeks Mini-Mental State Examination. The normal values are defined as: illiterates \>17, primary school \>20, junior high school or above \>24.
HAMA 8 weeks Hamilton Anxiety Scale. The total score ≥29 may be severe anxiety; ≥21, obvious anxiety; ≥14, definite anxiety; ≥7, may have anxiety; If the score \<7, there are no symptoms of anxiety.
QOLIE-31 scale scores 8 weeks Quality of Life in Epilepsy-31. Scores range from 0 to 100, with higher scores indicating better quality of life.
HAMD 8 weeks Hamilton Depression Scale. Total score \<7 means normal; between 7 and 17 means possible depression; between 17 and 24 , definitely have depression; \>24 means severe depression.
scalp electroencephalogram 8 weeks Routine scalp electroencephalogram at 40 min
SCL-90 8 weeks Self-reporting Inventory. The total symptom index scores ranged from 1 to 1.5, indicating that the subjects did not feel the symptoms listed in the scale. Between 1.5 and 2.5, indicates that the subject feels a little symptomatic, but not occur frequently. Between 2.5 and 3.5, indicates that the subject feels symptoms, and is mild to moderate. The score between 3.5 and 4.5 indicates that the subjects feel symptoms, and the degree was moderate to severe. A score between 4.5 and 5 indicates that the subject feels symptoms, and the frequency and intensity are very severe.
MQ 8 weeks Wechsler Memory Scale. Above 130 points very excellent, 120-129 excellent, 110-119 above average, 90-109 average, 80-89 below average, 70-79 critical level, below 69 mental retardation, 50-69 mild mental retardation, 35-49 moderate mental retardation, 20-34 severe mental retardation, less than 20 extremely severe mental retardation.
