Clinical study of deep brain magnetic stimulation technique in the treatment of Alzheimer's disease / 中华老年医学杂志

ABSTRACT

Objective To explore the effectiveness and safety of deep brain magnetic stimulation technique (dTMS) for treatment of Alzheimer's disease (AD).Methods Totally 116 patients with AD were randomly divided into 4 groups:(1) dTMS:given dTMS really stimulation therapy,(2)medication group:treatment with donepezil 5 mg/d,(3) combination treatment group:given dTMS and donepezil therapy,(4) blank control group:given pseudorandom stimulation treatment.33 healthy control cases were given dTMS's stimulation treatment.The treatment course was 6 months.Application of mini mental state examination scale (MMSE),the Montreal cognitive assessment scale (MoCA),Hamilton Depression Scale (HAMD),ischemic scale (HIS),Boston naming test,activity of daily living(ADL) and neuropsychological questionnaire (NPI) were used to evaluate the cognitive function.All the participants received blood tests and ECG in order to evaluate the safety of dTMS.Results After 6 months treatment,compair with the blank control group,all scale scoresof dTMS group,medication group and combined treatment group were improved significantly in MMSE (t=2.49,2.46,2.20),MoCA(t=2.59,2.39,2.87),ADL(t=2.35,2.17,2.83),NPI(t=3.05,2.40,2.65) and sub-cognitive scale score (all P＜0.05).All scale scores of combination treatment group were better than dTMS group and medication group (P＜0.05).There's no significant difference between drug treatment groups and dTMS group (P＞0.05).After 6 months treatment,compared with healthy control group,the scale scores were aggravated in 4 groups of AD (P＜0.05)Conclusions dTMS can be effective and safe in the treatment of AD patients with cognitive and noncognitive symptoms.
