Abstract Objective To observe the effect of repeated transcranial magnetic stimulation (rTMS) on serum brain-derived neurotrophic factor (BDNF) in elderly patients with mild cognitive impairment (MCI). Methods A total of 65 elderly patients with MCI who were admitted to Provincial Corps Hospital of Chinese People's Armed Police Force from January 2022 to October 2023 were included in the study, and divided into control group (n=32) and treatment group (n=33) by random number table method. In the control group,40mg of ginkgo biloba extract was taken orally (3 times/day) plus sham stimulation, while the treatment group received ginkgo biloba extract (manufacturer, specification, usage and dosage were the same as the control group) plus rTMS, and the primary disease was treated simultaneously in both groups. Serum BDNF was measured before treatment and 4 weeks after treatment, respectively, the clinical efficacy of the two groups before and after treatment was compared using the Simple Mental State Intelligence Scale (MMSE) and Montreal Cognitive Assessment Scale (MoCA) scores. Results After treatment, MMSE [(24.58±1.640) vs. (22.50±1.344)] and MoCA scores [(24.03±1.51) vs. (22.03±1.28)] in the treatment group were higher than those in the control group. MMSE [(24.58±1.64) vs. (22.97±1.78)] and MoCA [(24.03±1.51) vs. (21.88±1.75)] scores of the treatment group were significantly higher after treatment than those before treatment, and the differences were statistically significant (P＜0.05). After treatment, the serum BDNF level in the treatment group was significantly higher than that of the control group [(9.54±1.64) vs. (8.28±1.91)], and the serum BDNF level of the treatment group was higher than that before treatment [(9.54±1.64) vs. (7.93±1.62)], with statistically significant differences (P＜0.05). Conclusions Serum BDNF level is closely related to cognitive impairment in the elderly. rTMS therapy can increase the BDNF the level of BDNF in senile MCI patients and improve cognitive function, which is worthy of clinical promotion.
