Background: Studies have reported the use of repetitive transcranial magnetic stimulation (rTMS) in patients with major depressive disorder (MDD). However, most studies focus on antidepressant effect of rTMS, but few on cognitive aspects. The present study aimed to explore the effect of rTMS on BDNF levels and cognitive function in the treatment of middle-aged and elderly MDD.
Methods: This was a randomized controlled trial. A total of 120 elderly patients with MDD treated in The Second Affiliated Hospital of Xi'an Medical University from January 2021 to January 2023 were selected as research subjects. The patients were randomly divided into control group (n = 60, patients received simple oral treatment with escitalopram and sham rTMS) and study group (n = 60, patients received oral treatment with escitalopram combined with rTMS) according to the random number table method. We compared the clinical efficacy, serum BDNF levels, and cognitive function between the 2 groups.
Results: After treatment, the HAMD-17 score in the study group was lower than that in the control group [13.00 (12.00-16.00) vs 17.00 (15.00-19.00), P < .05], and the RBANS score was higher than that in the control group [166.00 (161.25-171.75) vs 133.00 (130.00-136.75), P < .05]. The total effective rate of the research group was 95.0%, which was higher than the 82.0% of the control group (P < .05). The serum BDNF levels [36.00 (33.00-38.00) vs 30.00 (28.00-32.00), P < .05] and MoCA scores [24.00 (22.00-26.75) vs 23.00 (21.00-25.00), P < .05] of the study group were higher than those of the control group. There were no significant adverse reactions during the treatment of both groups.
Conclusions: Compared with oral escitalopram alone, repeated transcranial magnetic stimulation in the treatment of middle-aged and elderly patients with major depressive disorder can further improve the efficacy, and can more effectively improve the BDNF level and cognitive function, with ideal safety.

Background: Dialectical behavioral therapy (DBT) and repetitive transcranial magnetic stimulation (rTMS) are both effective in treating borderline personality disorder (BPD). Impulsivity and impaired decision-making are prominent features of BPD, and therapeutic interventions targeting these symptoms could lead to significant improvements.
Objective/hypothesis: We hypothesized that intermittent theta burst stimulation (iTBS), a modified rTMS protocol that targets the left dorsolateral prefrontal cortex, would enhance the therapeutic effects of DBT, leading to greater improvements in impulsivity and decision-making compared with sham stimulation.

Background: In people with substance use disorders (SUDs), stress-exposure can impair executive function, and increase craving and likelihood of drug-use recurrence. Research shows that acute stressors increase drug-seeking behavior; however, mechanisms underlying this effect are incompletely understood. The Competing Neurobehavioral Decisions System theory posits that persons with SUDs may have hyperactive limbic reward circuitry and hypoactive executive control circuitry.

The purpose of the present study was to investigate the effects of neuromodulation techniques, including transcranial direct current stimulation, transcranial magnetic stimulation, and deep brain stimulation, on the treatments of nicotine dependence. Specifically, our objective was to assess the existing evidence by conducting an umbrella review of systematic reviews. The quality of the included studies was evaluated using the standardized tools designed to evaluate systematic reviews.

Background: Acute ischemic stroke (AIS) is a prevalent and challenging neurological condition associated with high mortality and morbidity rates. This study aimed to evaluate the therapeutic efficacy of repetitive transcranial magnetic stimulation (rTMS) combined with ginkgo diterpene lactone meglumine injection (GDLMI) on cognitive and neurological function recovery in patients with AIS.
Methods: A total of 120 patients with AIS, admitted between January 2021 and January 2022, received rTMS combined with GDLMI after admission.
