In recent years, non-invasive brain stimulation techniques, such as transcranial magnetic stimulation(TMS) and transcranial direct current stimulation, have emerged as therapeutic tools for neurology and neuroscience. However, the possible repercussions of these techniques remain unclear, and there are few reports on the incisive recovery mechanisms through brain stimulation. Although several studies have recommended the use of non-invasive brain stimulation in clinical neuroscience, with a special emphasis on TMS, the suggested mechanisms of action have not been confirmed directly at the neural level. Insights into the neural mechanisms of non-invasive brain stimulation would unveil the strategies necessary to enhance the safety and efficacy of this progressive approach. Therefore, animal studies investigating the mechanisms of TMSinduced recovery at the neural level are crucial for the elaboration of non-invasive brain stimulation. Translational research done using animal models has several advantages and is able to investigate knowledge gaps by directly targeting neuronal levels. In this review, we have discussed the role of TMS in different animal models, the impact of animal studies on various disease states, and the findings regarding brain function of animal models after TMS in pharmacology research.展开更多

Over 1 month, 1-Hz rTMS treatment was performed every 3 days. A battery of language production and functional MRI were evaluated in the patients using a standard verb generation task both before and 1 month after rTMS treatment. Significant and lasting improvement in verb production was observed following rTMS treatment. Functional MRI results revealed that the left frontal lobes of two patients were more activated than they had been prior to therapy, and activation was primarily concentrated in the language-related areas. Results demonstrated that low frequency rTMS has potential to improve language function in patients with refractory epilepsy.展开更多

Although this is a common method for clinical treatment of cerebral infarction, whether it promotes the recovery of motor function remains controversial. Twenty patients with cerebral infarction combined with hemiparalysis were equally and randomly divided into a low frequency rTMS group and a control group. The patients in the low frequency rTMS group were given 1-Hz rTMS to the contralateral primary motor cortex with a stimulus intensity of 90% motor threshold, 30 minutes/day. The patients in the control group were given sham stimulation. After 14 days of treatment, clinical function scores （National Institute of Health Stroke Scale, Barthel Index, and Fugl-Meyer Assessment） improved significantly in the low frequency rTMS group, and the effects were better than that in the control group. We conclude that low frequency （1 Hz） rTMS for 14 days can help improve motor function after cerebral infarction.展开更多

However, there are few studies concerning the use of different frequencies of repetitive transcranial magnetic stimulation on the recovery of upper-limb motor function after cerebral infarction. We hypothesized that different frequencies of repetitive transcranial magnetic stimulation in patients with cerebral infarction would produce different effects on the recovery of upper-limb motor function. This study enrolled 127 patients with upper-limb dysfunction during the subacute phase of cerebral infarction. These patients were randomly assigned to three groups. The low-frequency group comprised 42 patients who were treated with 1 Hz repetitive transcranial magnetic stimulation on the contralateral hemisphere primary motor cortex （M1）. The high-frequency group comprised 43 patients who were treated with 10 Hz repetitive transcranial magnetic stimulation on ipsilateral M1. Finally, the sham group comprised 42 patients who were treated with 10 Hz of false stimulation on ipsilateral M1. A total of 135 seconds of stimulation was applied in the sham group and high-frequency group. At 2 weeks after treatment, cortical latency of motor-evoked potentials and central motor conduction time were significantly lower compared with before treatment. Moreover, motor function scores were significantly improved. The above indices for the low- and high-frequency groups were significantly different compared with the sham group. However, there was no significant difference between the low- and high-frequency groups. The results show that low- and high-frequency repetitive transcranial magnetic stimulation can similarly improve upper-limb motor function in patients with cerebral infarction.展开更多

文摘Studies have shown that repetitive transcra nial magnetic stimulation(rTMS)can enhance synaptic plasticity and improve neurological dysfunction.Howeve r,the mechanism through which rTMS can improve moderate traumatic brain injury remains poorly understood.In this study,we established rat models of moderate traumatic brain injury using Feeney's weight-dropping method and treated them using rTMS.To help determine the mechanism of action,we measured levels of seve ral impo rtant brain activity-related proteins and their mRNA.On the injured side of the brain,we found that rTMS increased the protein levels and mRNA expression of brain-derived neurotrophic factor,tropomyosin receptor kinase B,N-methyl-D-aspartic acid receptor 1,and phosphorylated cAMP response element binding protein,which are closely associated with the occurrence of long-term potentiation.rTMS also partially reve rsed the loss of synaptophysin after injury and promoted the remodeling of synaptic ultrastructure.These findings suggest that upregulation of synaptic plasticity-related protein expression is the mechanism through which rTMS promotes neurological function recovery after moderate traumatic brain injury.

文摘Spinal cord injury is characte rized by diffe rent aetiologies,complex pathogenesis,and diverse pathological changes.Current treatments are not ideal,and prognosis is generally poor.After spinal cord injury,neurons die due to various forms of cell death.Among them,fe rroptosis causes dysfunction after spinal cord injury,and no existing traditional treatments have been indicated to block its occurrence.Meanwhile,emerging therapies using mesenchymal stem cells,extracellular vesicles,and transcranial magnetic stimulation therapy are promising for reve rsing spinal co rd neuronal ferroptosis after spinal cord injury.However,no definitive studies have demonstrated the effectiveness of these approaches.This review summarizes the existing research on the mechanisms of ferroptosis;fe rroptosis after spinal cord injury;treatment of spinal cord injury with mesenchymal stem cells,extracellular vesicles,and transc ranial magnetic stimulation;and treatment of ferroptosis using mesenchymal stem cells,extracellular vesicles,and transc ranial magnetic stimulation.Inhibiting ferroptosis can promote the reversal of neurological dysfunction after spinal cord injury.In addition,mesenchymal stem cells,extracellular vesicles,and transc ranial magnetic stimulation can reve rse adverse outcomes of spinal cord injury and regulate ferroptosis-related fa ctors.Thus,it can be inferred that mesenchymal stem cells,extracellular vesicles,and transcranial magnetic stimulation have the potential to inhibit fe rroptosis after spinal cord injury.This review serves as a reference for future research to confirm these conclusions.
文摘Deep transcranial magnetic stimulation(DTMS)is a new non-invasive neuromodulation technique based on repetitive transcranial magnetic stimulation technology.The new H-coil has significant advantages in the treatment and mechanism research of psychiatric and neurological disorders.This is due to its deep stimulation site and wide range of action.This paper reviews the clinical progress of DTMS in psychiatric and neurological disorders such as Parkinson’s disease,Alzheimer’s disease,post-stroke motor dysfunction,aphasia,and other neurological disorders,as well as anxiety,depression,and schizophrenia.
文摘BACKGROUND Postherpetic neuralgia(PHN)is a typical neuropathic pain condition that appears in the lesioned skin regions following the healing of shingles.The pain condition tends to persist,which is often accompanied by negative emotions(e.g.,anxiety and depression)and substantially reduces the quality of life.In addition to analgesia(e.g.,pregabalin and gabapentin),nerve radiofrequency technology is an effective treatment for intractable PHN.However,there is still a significant portion of patients who do not benefit from this treatment.As a non-invasive form of brain stimulation,repetitive transcranial magnetic stimulation(rTMS)targeting the motor cortex is able to reduce neuropathic pain with grade A evidence.CASE SUMMARY Here we report two cases in which motor cortex rTMS was used to treat intractable PHN that did not respond to initial drug and radiofrequency therapies.Moreover,we specifically investigated rTMS efficacy at 3 mo following treatment.CONCLUSION Motor cortex rTMS can treat intractable PHN that did not respond to initial drug and radiofrequency therapies.
文摘BACKGROUND Treatment-refractory schizophrenia(TRS),accounting for approximately 30%of all schizophrenia cases,has poor treatment response and prognosis despite treatment with antipsychotic drugs.AIM To analyze the therapeutic effectiveness of repetitive transcranial magnetic stimulation(rTMS)combined with olanzapine(OLZ)and amisulpride(AMI)for TRS and its influence on the patient’s cognitive function.METHODS This study enrolled 114 TRS patients who received treatment at the First Affiliated Hospital of Zhengzhou University between July 2019 and July 2022.In addition to the basic OLZ+AMI therapy,54 cases of the control group(Con group)received modified electroconvulsive therapy,while 60 cases of the research group(Res group)received rTMS.Data on therapeutic effectiveness,safety(incidence of drowsiness,headache,nausea,vomiting,or memory impairment),Positive and Negative Symptom Scale,Montreal Cognitive Assessment Scale,and Schizophrenia Quality of Life Scale were collected from both cohorts for comparative analyses.RESULTS The Res group elicited a higher overall response rate and better safety profile when compared with the Con group.Additionally,a significant reduction was observed in the post-treatment Positive and Negative Symptom Scale and Schizophrenia Quality of Life Scale scores of the Res group,presenting lower scores than those of the Con group.Furthermore,a significant increase in the Montreal Cognitive Assessment Scale score was reported in the Res group,with higher scores than those of the Con group.CONCLUSION The treatment of TRS with rTMS and OLZ+AMI is effective and safe.Moreover,it can alleviate the patients’mental symptoms,improve their cognitive function and quality of life,and has a high clinical application value.
文摘BACKGROUND Repetitive transcranial magnetic stimulation(rTMS)is a form of magnetic stimulation therapy used to treat depression,migraine,and motor function impairment in patients with stroke.As there is little research on the effects of rTMS in pregnant women,it is not widely used in these patients.This case report aimed to demonstrate the safety of rTMS in pregnant patients.CASE SUMMARY After much consideration,we applied rTMS to treat recent stroke and hemiplegia in a 34-year-old pregnant woman.The patient received 45 sessions of lowfrequency treatment over the course of 10 wk.We closely monitored the mother and fetus for potential side effects;the results showed significant improvement in the patient's motor function,with no harmful effects on the mother or fetus during pregnancy or after delivery.The patient’s fine motor and walking functions improved after treatment.This case is the first instance of a stroke patient treated with rTMS during pregnancy.CONCLUSION This case demonstrates that rTMS could be used to improve motor function recovery in stroke patients during pregnancy.
文摘BACKGROUND Dysphagia is a common condition in older as well as young patients,and a variety of treatments have been reported depending on the cause.However,clinicians are challenged when the cause is unclear.This is the case with psychogenic dysphagia,which has typically been treated with supportive psychotherapy,medi-cation,swallowing exercise,and dysphagia rehabilitation therapy.Here,we aimed to relieve the symptoms of a patient with refractory psychogenic dysphagia,who was unresponsive to conventional swallowing therapy,with repetitive transcranial magnetic stimulation(rTMS).CASE SUMMARY A relatively calm-looking 35-year-old female patient presented with a 2-year history of dysphagia.She showed little improvement with conventional swallowing treatments over the past 2 years.She was relatively compliant with inhospital dysphagia therapy,but uncooperative with home exercise and medication.In particular,since she was resistant to drug treatment,we had to take a different approach than the treatment she had been receiving for the past 2 years.After much deliberation,we decided to initiate antidepressant rTMS treatment with her consent(IRB No.2023-05-021).Antidepressant rTMS treatment was performed twice weekly for a total of 20 sessions over 10 wk.The results showed improvement in subjective symptoms and video fluoroscopic swallowing study findings.To the best of our knowledge,this is the first report of symptomatic improvement using antidepressant rTMS protocol for refractory psychogenic dysphagia.CONCLUSION This case demonstrates that rTMS with antidepressant protocol can be used to improve swallowing in patients with refractory psychogenic dysphagia.

文摘Objective:To investigate the clinical efficacy of intermittent theta burst stimulation(iTBS)and high frequency repetitive transcranial magnetic stimulation(rTMS)on post‑stroke executive impairment(PSEI).Methods:Ninety patients with PSEI who were hospitalized in the rehabilitation department of Xuzhou Central Hospital and Xuzhou Rehabilitation Hospital from April 2021 to June 2022 were selected and divided into iTBS group,high‑frequency group and control group.All three groups of patients received routine rehabilitation training,given rTMS treatment with iTBS,10 Hz and shame stimulation for 4 weeks.Before and after treatment,all the patients were evaluated with the Montreal cognitive assessment(MoCA),the frontal assessment battery(FAB),troop color‑word test(SCWT),shape trails test(STT),digit span test(DST)and event related potential P300.Results:After treatment,MoCA,FAB,SCWT,STT,DST scores,P300 latency and amplitude were significantly better in the three groups than before treatment(P<0.05).MoCA,FAB,SCWT,STT‑B,DST scores,P300 latency and amplitude in the iTBS group and high‑frequency group were better than in the control group,with significant differences(P<0.05).The difference between iTBS group and high‑frequency group was not statistically significant(P>0.05).Conclusion:iTBS can improve PSEI,and the efficacy is comparable to 10Hz rTMS.iTBS takes less time with better efficiency,and it is worth popularizing and applying in clinic.
文摘Brain stimulation techniques offer powerful means of modulating the physiology of specific neural structures. In recent years, non-invasive brain stimulation techniques, such as transcranial magnetic stimulation(TMS) and transcranial direct current stimulation, have emerged as therapeutic tools for neurology and neuroscience. However, the possible repercussions of these techniques remain unclear, and there are few reports on the incisive recovery mechanisms through brain stimulation. Although several studies have recommended the use of non-invasive brain stimulation in clinical neuroscience, with a special emphasis on TMS, the suggested mechanisms of action have not been confirmed directly at the neural level. Insights into the neural mechanisms of non-invasive brain stimulation would unveil the strategies necessary to enhance the safety and efficacy of this progressive approach. Therefore, animal studies investigating the mechanisms of TMSinduced recovery at the neural level are crucial for the elaboration of non-invasive brain stimulation. Translational research done using animal models has several advantages and is able to investigate knowledge gaps by directly targeting neuronal levels. In this review, we have discussed the role of TMS in different animal models, the impact of animal studies on various disease states, and the findings regarding brain function of animal models after TMS in pharmacology research.
文摘To investigate whether repetitive transcranial magnetic stimulation （rTMS） can improve language function in patients with refractory epilepsy, three right-handed, refractory epilepsy patients who had complained of language dysfunction, were recruited. Over 1 month, 1-Hz rTMS treatment was performed every 3 days. A battery of language production and functional MRI were evaluated in the patients using a standard verb generation task both before and 1 month after rTMS treatment. Significant and lasting improvement in verb production was observed following rTMS treatment. Functional MRI results revealed that the left frontal lobes of two patients were more activated than they had been prior to therapy, and activation was primarily concentrated in the language-related areas. Results demonstrated that low frequency rTMS has potential to improve language function in patients with refractory epilepsy.

文摘Low frequency （≤ 1 Hz） repetitive transcranial magnetic stimulation （rTMS） can affect the excitability of the cerebral cortex and synaptic plasticity. Although this is a common method for clinical treatment of cerebral infarction, whether it promotes the recovery of motor function remains controversial. Twenty patients with cerebral infarction combined with hemiparalysis were equally and randomly divided into a low frequency rTMS group and a control group. The patients in the low frequency rTMS group were given 1-Hz rTMS to the contralateral primary motor cortex with a stimulus intensity of 90% motor threshold, 30 minutes/day. The patients in the control group were given sham stimulation. After 14 days of treatment, clinical function scores （National Institute of Health Stroke Scale, Barthel Index, and Fugl-Meyer Assessment） improved significantly in the low frequency rTMS group, and the effects were better than that in the control group. We conclude that low frequency （1 Hz） rTMS for 14 days can help improve motor function after cerebral infarction.

文摘Studies have confirmed that low-frequency repetitive transcranial magnetic stimulation can decrease the activity of cortical neurons, and high-frequency repetitive transcranial magnetic stimulation can increase the excitability of cortical neurons. However, there are few studies concerning the use of different frequencies of repetitive transcranial magnetic stimulation on the recovery of upper-limb motor function after cerebral infarction. We hypothesized that different frequencies of repetitive transcranial magnetic stimulation in patients with cerebral infarction would produce different effects on the recovery of upper-limb motor function. This study enrolled 127 patients with upper-limb dysfunction during the subacute phase of cerebral infarction. These patients were randomly assigned to three groups. The low-frequency group comprised 42 patients who were treated with 1 Hz repetitive transcranial magnetic stimulation on the contralateral hemisphere primary motor cortex （M1）. The high-frequency group comprised 43 patients who were treated with 10 Hz repetitive transcranial magnetic stimulation on ipsilateral M1. Finally, the sham group comprised 42 patients who were treated with 10 Hz of false stimulation on ipsilateral M1. A total of 135 seconds of stimulation was applied in the sham group and high-frequency group. At 2 weeks after treatment, cortical latency of motor-evoked potentials and central motor conduction time were significantly lower compared with before treatment. Moreover, motor function scores were significantly improved. The above indices for the low- and high-frequency groups were significantly different compared with the sham group. However, there was no significant difference between the low- and high-frequency groups. The results show that low- and high-frequency repetitive transcranial magnetic stimulation can similarly improve upper-limb motor function in patients with cerebral infarction.
