LIFE SCIENCES IN SPACE RESEARCH 2024; 42:17-26. [PMID: 39067986 DOI: 10.1016/j.lssr.2024.04.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Revised: 03/27/2024] [Accepted: 04/03/2024] [Indexed: 07/30/2024]
Abstract
Studies have indicated that medium- to long-duration spaceflight may adversely affect astronauts' emotional and social functioning. Emotion modulation can significantly impact astronauts' well-being, performance, mission safety and success. However, with the increase in flight time, the potential alterations in emotional and social performance during spaceflight and their underlying mechanisms remain to be investigated, and targeted therapeutic and preventive interventions have yet to be identified. We evaluated the changes of emotional and social functions in mice with the extension of the time in simulated space complex environment (SSCE), and simultaneously monitored changes in brain tissue of vascular endothelial growth factor (VEGF), matrix metalloproteinase-9 (MMP-9), and inflammation-related factors. Furthermore, we assessed the regulatory role of repetitive transcranial magnetic stimulation (rTMS) in mood and socialization with the extension of the time in SSCE, as well as examining alterations of VEGF signaling in the medial prefrontal cortex (mPFC). Our findings revealed that mice exposed to SSCE for 7 days exhibited depressive-like behaviors, with these changes persisting throughout SSCE period. In addition, 14 days of rTMS treatment significantly ameliorated SSCE-induced emotional and social dysfunction, potentially through modulation of the level of VEGF signaling in mPFC. These results indicates that emotional and social disorders increase with the extension of SSCE time, and rTMS can improve the performance, which may be related to VEGF signaling. This study offers insights into potential pattern of change over time for mental health issues in astronauts. Further analysis revealed that rTMS modulates emotional and social dysfunction during SSCE exposure, with its mechanism potentially being associated with VEGF signaling.

Abstract
NONE Insomnia is highly prevalent and challenging to treat. We typically regard insomnia as a disorder of the modern world, but physicians and patients have been struggling with this malady for millennia. Here we present the curious historical practice of using electrization or faradization to treat insomnia. We present methods of application, hypotheses regarding mechanism of action, and historical case reports and case series to better understand this phenomenon. We put faradization for insomnia in the context of the modern use of electrical therapies to support and facilitate human health in multiple different health care arenas. Last, we examine current efforts to use these antiquated concepts to address insomnia through transcranial direct current stimulation and cranial electrical stimulation.

Abstract
BACKGROUND Major depressive disorder (MDD) affects 10% of pregnancies. Because transcranial magnetic stimulation (TMS) is a nonmedication option, psychiatric patients who do not tolerate or prefer to avoid antidepressants are good candidates for TMS. METHOD In a randomized controlled trial of twenty-two women with MDD in the second or third trimester of pregnancy, subjects were randomized to active TMS (n=11) or sham TMS (n=11). This study took place at a single academic center. Subjects received 20 sessions of TMS to the right dorsolateral prefrontal cortex at 1 Hz as a single train of 900 pulses per session at 100% motor threshold. Estradiol and progesterone and were measured before session 1 and after session 20. RESULTS Results demonstrated significantly decreased Hamilton Depression Rating Scale (HDRS-17) scores for the active compared to the sham group (p=0.003). Response rates were 81.82% for the active and 45.45% for the sham coil (p=0.088). Remission rates were 27.27% for the active 18.18% for the sham coil (p=0.613). Late preterm birth (PTB) occurred in three women receiving active TMS. All other maternal and delivery outcomes were normal. CONCLUSIONS Right-sided, low frequency TMS was effective in reducing depressive symptoms in this sample of pregnant women. There may be a possibility that TMS is associated with late PTB although a larger sample size would be needed for adequate power to detect a true difference between groups. This study demonstrated that TMS is low risk during pregnancy although larger trials would provide more information about the efficacy and safety of TMS in this population. This trial shows that an RCT of a biologic intervention in pregnant women with psychiatric illness can be conducted.

Abstract
Noninvasive brain stimulation, using electromagnetic waves (repetitive transcranial magnetic stimulation (rTMS)) and direct electrical current (transcranial direct current stimulation (tDCS)), is a new frontier in treating psychiatric maladies. While still being developed as viable treatment options, both options have had numerously reported side-effects, with hypomania being a significant concern during investigations. While there has been a relatively rare incidence of hypomania among rTMS/tDCS trials, it still posits an important issue regarding the safety of both treatment modalities. This review studies the reported episodes of hypomania in rTMS and tDCS trials in order to identify any patterns that may cause the same. Such patterns included higher stimulation strengths with long stimulation periods. These factors, if modified, along with an established regimen of screening and prophylaxis against hypomanic risks, may be effective protection against hypomania, as well as to prevent manic episodes.

Abstract
Transcranial magnetic stimulation (rTMS) and sleep deprivation (SD) are two of the latest advances made in the field of psychiatric research. Though yet in development, they present unique opportunities to achieve significant clinical outcomes particularly in major depression disorder (MDD). A limited set of studies have been done in the combined use of rTMS-SD in treating MDD. While promising, these studies have been hampered by the limited knowledge of rTMS and SD themselves due to their relatively recent use as viable therapeutic options. This review is aimed at an analysis of the limitations observed in the studies conducted to date involving rTMS and SD. In addition, it explores the potential new avenues for future research in the deployment of rTMS-SD as a viable treatment option.

Abstract
OBJECTIVE to examine the EEG spectral characteristics during TMS in resistant depression therapy. MATERIAL AND METHODS The sample consisted of 32 depressive patients diagnosed with recurrent depressive disorder or bipolar affective disorder. TMS, as well as EEG, were conducted during the previous inefficient thymoanaleptic therapy with reduced doses. TMS was performed in the left prefrontal cortex. Treatment course consisted of 15 procedures with 100% threshold intensity. During a single procedure, the patient received 20 cycles of stimulation pulses with the frequency of 15 Hz, duration of 20 seconds and interval of 60 seconds between single cycles. EEG was recorded with the use of the «NEURO-KM» apparatus (Russia) with band pass from 0.5 to 45 Hz and time constant of 0.3 sec before and after the course of TMS. Spectroscopic analysis of EEG was conducted using the Fast Furies Transformation analysis with average of no less than 30 periods for 2 seconds with subsequent mapping with the use of the «BRAINSYS» system (Russia). RESULTS AND CONCLUSION After conducting TMS, EEG changes were generalized and included the reconstruction of all frequencies of the electrical brain activity. However, the major changes were seen in alpha-rhythm spectrums: its index increased in all cortical areas, mostly in the occipital cortex, thereby forming the alpha-rhythm focus in these areas.

Efficacy and acceptability of high frequency repetitive transcranial magnetic stimulation (rTMS) versus electroconvulsive therapy (ECT) for major depression: a systematic review and meta-analysis of randomized trials. Depress Anxiety 2013; 30:614-23.

Abstract
Clinical trials comparing the efficacy and acceptability of high frequency repetitive transcranial magnetic stimulation (HF-rTMS) and electroconvulsive therapy (ECT) for treating major depression (MD) have yielded conflicting results. As this may have been the result of limited statistical power, we have carried out this meta-analysis to examine this issue. We searched the literature for randomized trials on head-to-head comparisons between HF-rTMS and ECT from January 1995 through September 2012 using MEDLINE, EMBASE, PsycINFO, Cochrane Central Register of Controlled Trials, and SCOPUS. The main outcome measures were remission rates, pre-post changes in depression ratings, as well as overall dropout rates at study end. We used a random-effects model, Odds Ratios (OR), Number Needed to Treat (NNT), and Hedges' g effect sizes. Data were obtained from 7 randomized trials, totalling 294 subjects with MD. After an average of 15.2 HF-rTMS and 8.2 ECT sessions, 33.6% (38/113) and 52% (53/102) of subjects were classified as remitters (OR = 0.46; p = 0.04), respectively. The associated NNT for remission was 6 and favoured ECT. Also, reduction of depressive symptomatology was significantly more pronounced in the ECT group (Hedges' g = -0.93; p = 0.007). No differences on dropout rates for HF-rTMS and ECT groups were found. In conclusion, ECT seems to be more effective than HF-rTMS for treating MD, although they did not differ in terms of dropout rates. Nevertheless, future comparative trials with larger sample sizes and better matching at baseline, longer follow-ups and more intense stimulation protocols are warranted.

Changes in hypothalamic-pituitary-thyroid axis following successful treatment with low-frequency right prefrontal transcranial magnetic stimulation in treatment-resistant depression. Psychiatry Res 2010; 175:74-7.

Abstract
Hypothalamic-pituitary-thyroid (HPT) axis abnormalities have been reported in some patients with major depression. To knowledge, however, the effects of low-frequency right prefrontal transcranial magnetic stimulation (TMS) on the HPT axis have not yet been elucidated. The goal of this study was to evaluate alterations in the HPT axis associated with the therapeutic efficacy of TMS treatments. Twenty patients with treatment-resistant depression received five 60-s 1-Hz trains over the right dorsolateral prefrontal cortex. Twelve treatment sessions were administered within a 3-week period (total pulses, 3600). Responders were defined as a > or =50% decrease in the Hamilton Depression Rating Scale (HDRS) score. Serum levels of thyroid-stimulating hormone (TSH), free triiodothyronine (fT3), and free thyroxine (fT4) were measured, respectively, at pre- and post-treatment. There were no significant changes in fT3 and fT4 levels measured at either pre- or post-treatment in either responders or nonresponders; however, TSH levels of responders elevated significantly after TMS treatments. In addition, there was a significant negative correlation between TSH levels at pretreatment and decrease (%) in the HDRS score. These findings suggest that the HPT axis is associated with antidepressant effects of low-frequency right prefrontal TMS, and indicate that lower TSH levels at pre-treatment are correlated with better therapeutic efficacy.

Abstract
The treatment of major depressive disorder during pregnancy is an important but complex clinical topic. Medications, electroconvulsive therapy, and psychotherapy are all reasonable choices, but each has its limitations. In this article, we propose that a novel device technology known as repetitive transcranial magnetic stimulation should be systematically studied as a potential treatment option for women with major depressive disorder during pregnancy.

Abstract
BACKGROUND Recent studies indicate that medication resistant depressed patients can be successfully treated by a series of sessions of High Frequency repetitive Transcranial Magnetic Stimulation (HF-rTMS), delivered on the left dorsolateral prefrontal cortex (DLPFC). However, changes in subjectively experienced mood give only limited insight into the underlying physiological responses. Previous studies in depressed patients, as well as in healthy volunteers, have reported a possible impact of HF-rTMS on the hypothalamic-pituitary-adrenal (HPA) axis. OBJECTIVE We wanted to evaluate the emotional and neurobiological impact of one session of HF-rTMS applied on the left DLPFC in a sample of unipolar treatment resistant depressed patients of the melancholic subtype. METHODS 20 right-handed antidepressant-free depressed patients were studied using a sham-controlled, 'single' blind, crossover design. We examined subjective mood changes with Visual Analogue Scales (VAS). To examine HF-rTMS effects on the HPA-axis, we analyzed salivary cortisol levels. Mood assessment and salivary cortisol levels were assessed before and immediately after stimulation. To detect any delayed effects, all measurements were also re-assessed 30 min post HF-rTMS. The left DLPFC was determined under MRI guidance. RESULTS One session of HF-rTMS did not result in any subjectively experienced mood changes. However, salivary cortisol concentrations decreased significantly immediately and 30 min after active HF-rTMS. CONCLUSIONS Although one session of HF-rTMS on the left DLPFC did not influence mood subjectively in melancholic unipolar depressed patients, we found support for the hypothesis that a single session has a significant impact on the HPA-axis, as measured by salivary cortisol. Our results may provide more insight into the underlying working mechanisms of HF-rTMS in unipolar melancholic depression, and could add further information about endocrinological functioning in affective disorders.

Abstract
Treatment for anxiety and post-traumatic stress disorder (PTSD) includes exposure therapy and medications, but some patients are refractory. Few studies of repetitive transcranial magnetic stimulation (rTMS) for anxiety or PTSD exist. In this preliminary report, rTMS was combined with exposure therapy for PTSD. Nine subjects with chronic, treatment-refractory PTSD were studied in a placebo-controlled, crossover design of imaginal exposure therapy with rTMS (1Hz) versus sham. PTSD symptoms, serum and 24h urine were obtained and analyzed. Effect sizes for PTSD symptoms were determined using Cohen's d. Active rTMS showed a larger effect size of improvement for hyperarousal symptoms compared to sham; 24-h urinary norepinephrine and serum T4 increased; serum prolactin decreased. Active rTMS with exposure may have symptomatic and physiological effects. Larger studies are needed to confirm these preliminary findings and verify whether rTMS plus exposure therapy has a role in the treatment of PTSD.

Abstract
In spite of recent developments in the pharmacotherapy of depressive disorders, the delay until clinical improvement can be achieved, and the considerable rate of nonresponse and nonremission, are major problems which remain unresolved. Electroconvulsive therapy (ECT) is a nonpharmacologic biological treatment which has been proven to be a highly effective treatment option, predominantly for depression, but also for schizophrenia and other indications. Though there is a lack of controlled investigations on long-term treatments, ECT can also be used for relapse prevention during maintenance therapies. The safety and tolerability of electroconvulsive treatment have been enhanced by the use of modified stimulation techniques and by progress in modern anesthesia. Thus, today a safe treatment can also be offered to patients with higher somatic risks. ECT still represents an important option, especially in the therapy of treatment-resistant psychiatric disorders after medication treatment failures. Earlier consideration of ECT may reduce the rate of chronic and difficult-to-treat psychiatric disorders.

Abstract
Alzheimer disease (AD) is the most common form of dementia. Different pathogenic processes have been studied that underlie characteristic changes of AD, including A beta protein aggregation, tau phosphorylation, neurovascular dysfunction, and inflammatory processes. Insulin exerts pleiotropic effects in neurons, such as the regulation of neural proliferation, apoptosis, and synaptic transmission. In this setting, any disturbance in the metabolism of insulin in the central nervous system (CNS) may put unfavorable effects on CNS function. It seems that disturbances in insulin metabolism, especially insulin resistance, play a role in most pathogenic processes that promote the development of AD. In this article, the relationships of disturbances in the metabolism of insulin in CNS with A beta peptides aggregation, tau protein phosphorylation, inflammatory markers, neuron apoptosis, neurovascular dysfunction, and neurotransmitter modulation are discussed, and future research directions are provided.

Abstract
Clinical and epidemiological studies have consistently observed the heterogeneous symptomatology and course of geriatric depression. Given the importance of genetic and environmental risk factors, aging processes, neurodegenerative and cerebrovascular disease processes, and medical comorbidity, the integration of basic and clinical neuroscience research approaches is critical for the understanding of the variability in illness course, as well as the development of prevention and intervention strategies that are more effective. These considerations were the impetus for a workshop, sponsored by the Geriatrics Research Branch in the Division of Adult Translational Research and Treatment Development of the National Institute of Mental Health that was held on September 7-8, 2005. The primary goal of the workshop was to bring together investigators in geriatric psychiatry research with researchers in specific topic areas outside of geriatric mental health to identify priority areas to advance translational research in geriatric depression. As described in this report, the workshop focused on a discussion of the development and application of integrative approaches combining genetics and neuroimaging methods to understand such complex issues as treatment response variability, the role of medical comorbidity in depression, and the potential overlap between depression and dementia. Future directions for integrative research were identified. Understanding the nature of geriatric depression requires the application of translational research and interdisciplinary research approaches. Geriatric depression could serve as a model for translational research integrating basic and clinical neuroscience approaches that would have implications for the study of other neuropsychiatric disorders.

Abstract
Electroconvulsive therapy (ECT) is used in the therapy of severe psychiatric disorders. The treatment, in which a generalized epileptic seizure is provoked by electrical stimulation of the brain, is performed under anaesthesia and muscle relaxation. Considering careful previous clinical examination and anaesthesiological and internal contraindications, ECT is a safe form of treatment. The following review is intended to familiarize with ECT and to provide advice for the anaesthesiological management.

Abstract
Until recently, a review of nonpharmacological, somatic treatments of psychiatric disorders would have included only electroconvulsive therapy (ECT). This situation is now changing very substantially. Although ECT remains the only modality in widespread clinical use, several new techniques are under investigation. Their principal indication in the psychiatric context is the treatment of major depression, but other applications are also being studied. All the novel treatments involve brain stimulation, which is achieved by different technological methods. The treatment closest to the threshold of clinical acceptability is transcranial magnetic stimulation (TMS). Although TMS is safe and relatively easy to administer, its efficacy has still to be definitively established. Other modalities, at various stages of research development, include magnetic seizure therapy (MST), deep brain stimulation (DBS), and vagus nerve stimulation (VNS). We briefly review the development and technical aspects of these treatments, their potential role in the treatment of major depression, adverse effects, and putative mechanism of action. As the only one of these treatment modalities that is in widespread clinical use, more extended consideration is given to ECT Although more than half a century has elapsed since ECT was first introduced, it remains the most effective treatment for major depression, with efficacy in patients refractory to antidepressant drugs and an acceptable safety profile. Although they hold considerable promise, the novel brain stimulation techniques reviewed here will be need to be further developed before they achieve clinical acceptability.

Abstract
Major depression is a debilitating and recurrent disorder with a substantial lifetime risk and a high social cost. Depressed patients generally display co-morbid symptoms, and depression frequently accompanies other serious disorders. Currently available drugs display limited efficacy and a pronounced delay to onset of action, and all provoke distressing side effects. Cloning of the human genome has fuelled expectations that symptomatic treatment may soon become more rapid and effective, and that depressive states may ultimately be "prevented" or "cured". In pursuing these objectives, in particular for genome-derived, non-monoaminergic targets, "specificity" of drug actions is often emphasized. That is, priority is afforded to agents that interact exclusively with a single site hypothesized as critically involved in the pathogenesis and/or control of depression. Certain highly selective drugs may prove effective, and they remain indispensable in the experimental (and clinical) evaluation of the significance of novel mechanisms. However, by analogy to other multifactorial disorders, "multi-target" agents may be better adapted to the improved treatment of depressive states. Support for this contention is garnered from a broad palette of observations, ranging from mechanisms of action of adjunctive drug combinations and electroconvulsive therapy to "network theory" analysis of the etiology and management of depressive states. The review also outlines opportunities to be exploited, and challenges to be addressed, in the discovery and characterization of drugs recognizing multiple targets. Finally, a diversity of multi-target strategies is proposed for the more efficacious and rapid control of core and co-morbid symptoms of depression, together with improved tolerance relative to currently available agents.

Abstract
Transcranial magnetic stimulation (TMS) is a patient-friendly stimulation technique of the brain with interesting perspectives. In clinical psychiatry, limited data are available on activity in psychosis and anxiety, but much research has been done in depression. Major concerns on published papers are the inconsistency of used parameter settings, the restraint numbers of patients in randomised trials, the lack of real sham controlled studies and the quasi inexistent reproducibility of results. The most stringent meta-analysis of TMS in affective disorders found a modest, statistically significant antidepressant effect after 2 weeks of daily treatment of high frequency repetitive left dorsolateral prefrontal cortex stimulation. Although most results are rather weak and not convincing enough to promote TMS as evidence-based antidepressive therapy, they show a measurable action that should not be ignored. Preclinical and clinical effects were observed analysing heterogeneous data, and results comparing TMS to electroconvulsive therapy (ECT) in affective disorders are encouraging. Efforts should continue with emphasis on increasing homogeneity and reproducibility in data. Further refinement of stimulation parameters should be established, so that new and large double-blind, long-term, sham-controlled trials can bring us to better understanding and standardising TMS procedure, finally leading to definitive conclusions about its efficacy in psychiatry.

Abstract
The management of depression in subjects aged over 65 is based on the isolated or combined use of antidepressant chemotherapy, psychotherapy and electroconvulsive therapy. Electroconvulsive therapy, under general anaesthesia and use of curare, consists in producing a generalised seizure using a short, pulsed, electrical current administered via the transcranial route. There is renewed interest in electroconvulsive therapy with the development of specific rules and conditions for its use, together with the recruitment of depressed patients resistant to classical treatments in hospital settings. The efficacy of electroconvulsive therapy has been demonstrated in the elderly. The immediate side effects, related to the electrical stimulation and the seizure, such as headaches, nausea, confusion, and transient amnesia, regress within a few minutes or hours after the session. The limits of electroconvulsive therapy are the high risk of relapse on suspension of the sessions, relapse basically related to the severity of the depression. Consolidation electroconvulsive therapy provides new hope for better control of such relapses.

Abstract
Selective serotonin reuptake inhibitors, such as fluoxetine (FLX), are the most commonly used drugs in the treatment of major depression. However, there is a limited understanding of their molecular mechanism of action. Although the acute effect of selective serotonin reuptake inhibitors in elevating synaptic serotonin concentrations is well known, the clinical amelioration of depressive symptoms requires 14-21 days of treatment, suggesting that numerous other rearrangements of function in the CNS must take place. In the present study, we demonstrated that 14 days of FLX treatment up-regulated galanin mRNA levels by 100% and GalR2-binding sites by 50%, in the rat dorsal raphe nucleus, where galanin coexists with serotonin. Furthermore, a galanin receptor antagonist, M40, attenuated the antidepressant-like effect of FLX in the forced swim test, a rodent preclinical screen commonly used to evaluate antidepressant-like efficacy. Direct activation of galanin receptors by a galanin receptor agonist, galnon, was found to produce an antidepressant-like effect in the same task. Two other antidepressant treatments also affected the galaninergic system in the monoaminergic nuclei: Electroconvulsive shock elevated galanin mRNA levels in dorsal raphe nucleus, whereas sleep deprivation increased galanin mRNA levels in the locus coeruleus, further underlining the connection between activation of the galaninergic system and antidepressant action of various clinically proven treatments.

Abstract
BACKGROUND Many severely depressed patients do not benefit from or tolerate existing treatments. Repetitive transcranial magnetic stimulation (rTMS) has been reported to benefit depression. We compared rTMS to electroconvulsive therapy (ECT) in severely ill, depressed patients. METHODS Twenty-five patients with a major depression (unipolar or bipolar) deemed clinically appropriate for ECT were randomly assigned to rTMS (10-20 treatments, 10 Hz, 110% motor threshold applied to the left dorsolateral prefrontal cortex for a total of 10,000-20,000 stimulations) or a course of bitemporal ECT (4-12 treatments). The primary outcome measure was the 24-item Hamilton Depression Rating Scale (HDRS). The Brief Psychiatric Rating Scale (BPRS), Young Mania Rating Scale (YMS), and Clinical Global Impression scale (CGI) were secondary measures. Minimal rescue medications were utilized. RESULTS Mean percent improvement on the baseline HDRS score did not significantly differ between the two treatments (i.e., 55% for the rTMS group vs. 64% for the ECT group [p = ns]). With response defined as a 50% reduction from baseline and a final score < or = 8 on the HDRS, there was also no significant difference between the two groups. We did not observe any differences between groups on the secondary measures. CONCLUSIONS A 2-4 week randomized, prospective trial comparing rTMS to ECT produced comparable therapeutic effects in severely depressed patients.

Abstract
BACKGROUND Transcranial magnetic stimulation can either excite or inhibit cortical areas of the brain, depending on whether the speed of the repetitive stimulation is applied at high or low frequencies. It has been used for physiological studies and it has also been proposed as a treatment for depression. OBJECTIVES To assess the clinical efficacy and safety of transcranial magnetic stimulation for treating depression. SEARCH STRATEGY An electronic search was performed including the Cochrane Collaboration Depression, Neurosis and Anxiety Review Group trials register (last searched June, 2001), the Cochrane Controlled Trials Register (Issue 2, 2001), MEDLINE (1966-2001), EMBASE (1974-2001), PsycLIT (1980-2001), and bibliographies from reviewed articles. Unpublished data and grey literature were searched through personal communications with researchers. SELECTION CRITERIA Randomised controlled trials assessing the therapeutic efficacy and safety of transcranial magnetic stimulation for depression. DATA COLLECTION AND ANALYSIS All reviewers independently extracted the information and verified it by cross-checking. Disagreements were resolved through discussion. Continuous data: When similar studies were grouped, the overall standardised mean difference was calculated under a fixed effect model weighted by the inverse variance method with 95% confidence intervals. (In the presence of statistical heterogeneity, a random effects model was to be used.) MAIN RESULTS Sixteen trials were included in the review and fourteen contained data in a suitable form for quantitative analysis. Most comparisons did not show differences between rTMS and other interventions. No difference was seen between rTMS and sham TMS using the Beck Depression Inventory or the Hamilton Depression Rating Scale, except for one time period (after two weeks of treatment) for left dorsolateral prefrontal cortex and high frequency; and also for right dorsolateral prefrontal cortex and low frequency, both in favour of rTMS and both using the Hamilton scale. Comparison of rTMS (left dorsolateral prefrontal cortex and high frequency) with electroconvulsive therapy showed no difference except for psychotic patients after two weeks treatment, using the Hamilton scale, which indicated that electroconvulsive therapy was more effective than rTMS. REVIEWER'S CONCLUSIONS The information in this review suggests that there is no strong evidence for benefit from using transcranial magnetic stimulation to treat depression, although the small sample sizes do not exclude the possibility of benefit.

Abstract
New knowledge about the specific brain regions involved in neuropsychiatric disorders is rapidly evolving due to recent advances in functional neuroimaging techniques. The ability to stimulate the brain in awake alert adults without neurosurgery is a real advance that neuroscientists have long dreamed for. Several novel and minimally invasive techniques to stimulate the brain have recently developed. Among these newer somatic interventions, transcranial magnetic stimulation (TMS), vagus nerve stimulation (VNS) and deep brain stimulation (DBS) show promise as therapeutic tools in the treatment of neuropsychiatric disorders. This article reviews the history, methodology, and the future of these minimally invasive brain stimulation (MIBS) techniques and their emerging research and therapeutic applications in psychiatry
