BACKGROUND: This is an updated version of the original Cochrane Review published in 2010, Issue 9, and last updated in 2014, Issue 4. Non-invasive brain stimulation techniques aim to induce an electrical stimulation of the brain in an attempt to reduce chronic pain by directly altering brain activity. They include repetitive transcranial magnetic stimulation (rTMS), cranial electrotherapy stimulation (CES), transcranial direct current stimulation (tDCS), transcranial random noise stimulation (tRNS) and reduced impedance non-invasive cortical electrostimulation (RINCE)...

Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive technique with few side effects that has been reported to be effective in the treatment of major depressive disorder (MDD). At present, no randomized controlled trials (RCT) have compared the efficacy and safety of rTMS delivered by the figure-8-coil and the H1-coil. We describe an industry-independent, randomized, controlled, single-blinded, single-center study protocol assessing the differences in efficacy and safety of rTMS for patients diagnosed with MDD with the H1-coil and figure-8-coil as an add-on to stable pharmacotherapy or pharmacotherapy alone...

Patients with autism spectrum disorder (ASD) display abnormalities in neuronal development, synaptic function and neural circuits. The imbalance of excitatory and inhibitory (E/I) synaptic transmission has been proposed to cause the main behavioral characteristics of ASD. Repetitive transcranial magnetic stimulation (rTMS) can directly or indirectly induce excitability and synaptic plasticity changes in the brain noninvasively. However, whether rTMS can ameliorate autistic-like behaviors in animal model via regulating the balance of E/I synaptic transmission is unknown...

Not all depression patients effectively respond to repeated transcranial magnetic stimulation (rTMS). We tested whether the intrinsic functional connectivity (FC) strength between the stimulated left dorsolateral prefrontal cortex (DLPFC) and left nucleus accumbens (NAcc) might predict effects of rTMS. Twenty-two medication-naïve depression patients received rTMS on left DLPFC for 2 weeks and underwent baseline functional magnetic resonance imaging (fMRI). We compared the amplitude of the low-frequency fluctuation (ALFF) and regional homogeneity (ReHo) in the stimulated target (the cortex region directly stimulated by rTMS) located in the left DLPFC, and the left NAcc, as well as the intrinsic FC of the DLPFC-NAcc between early improvers and non-improvers...

BACKGROUND: Repetitive transcranial magnetic stimulation (rTMS) is able to modify cortical excitability. Rat rTMS studies revealed a modulation of inhibitory systems, in particular that of the parvalbumin-expressing (PV+) interneurons, when using intermittent theta-burst stimulation (iTBS). OBJECTIVE: The potential disinhibitory action of iTBS raises the questions of how neocortical circuits stabilize excitatory-inhibitory balance within a physiological range. Neuropeptide Y (NPY) appears to be one candidate...

While brain stimulation techniques have been examined as treatment options for chronic tinnitus for many years, they have recently been extended to multimodal treatment approaches. As chronic tinnitus is often accompanied by comorbid muscular tension in the neck and back, we performed a one-arm pilot study to explore the feasibility of a new multimodal treatment approach. In detail, repetitive peripheral magnetic stimulation (rPMS) of the back was performed before and after each session of repetitive transcranial magnetic stimulation (rTMS) of the brain...

Apraxia (a disorder of complex movement) suggests that the left inferior parietal lobule plays a role in kinematic or spatial aspects of imitation, which may be particularly important for meaningless (i.e., unfamiliar intransitive) actions. Mirror neuron theories indicate that the inferior parietal lobule is part of a frontoparietal system that can support imitation by linking observed and stored actions through visuomotor matching, and have less to say about different subregions of the left inferior parietal lobule, or how different types of action (i...

Background: Based on the hyperexcitability and disinhibition observed in patients with restless legs syndrome (RLS) following transcranial magnetic stimulation (TMS), we conducted a study with low-frequency repetitive TMS (rTMS) over the primary motor (M1) and somatosensory cortical areas (S1) in patients with RLS. Methods: A total of 13 right-handed patients and 10 age-matched controls were studied using clinical scales and TMS. Measurements included resting motor threshold (rMT), motor-evoked potentials (MEPs), cortical silent period (CSP), and central motor conduction time (CMCT)...

Repetitive transcranial magnetic stimulation (rTMS) is commonly used to modulate cortical plasticity in clinical and non-clinical populations. Clinically, rTMS is delivered to targeted regions of the cortex at high intensities (>1 T). We have previously shown that even at low intensities, rTMS induces structural and molecular plasticity in the rodent cortex. To determine whether low intensity rTMS (LI-rTMS) alters behavioural performance, daily intermittent theta burst LI-rTMS (120 mT) or sham was delivered as a priming or consolidating stimulus to mice completing 10 consecutive days of skilled reaching training...

BACKGROUND: Impulsivity is a multi-faceted concept. It is a crucial feature of many neuropsychiatric disorders. Three subtypes of impulsivity have been identified: motor, temporal, and cognitive impulsivity. Existing evidence suggests that the right inferior frontal gyrus (rIFG) plays a crucial role in impulsivity, and such a role has been elucidated using inhibitory repetitive transcranial magnetic stimulation (rTMS). There is a dearth of studies using excitatory rTMS at the rIFG, an important gap in the literature this study aimed to address...

Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive therapy that has been implicated in treatment of serious neurological disorders. However, the neurobiological mechanisms underlying the effects of rTMS remain unclear. Therefore, this study examined the differential effects of repetitive magnetic stimulation (rMS) in an in vitro neuronal model of ischemia/reperfusion (I/R) injury, depending on low and high frequency. Neuro-2a cells were differentiated with retinoic acid and established for in vitro neuronal model of I/R injury under a subsequent 3 h of oxygen and glucose deprivation/reoxygenation (OGD/R) condition...

BACKGROUND: High rates of tobacco smoking and smoking cessation failure in schizophrenia may be related to prefrontal cortical dysfunction. Novel treatment options for tobacco use disorder are needed given the limited efficacy of current pharmacotherapies. Preliminary evidence suggests high-frequency repetitive transcranial magnetic stimulation (rTMS) to bilateral dorsolateral prefrontal cortex (DLPFC) may suppress tobacco craving in smokers with schizophrenia. The goal of this study was to determine effects of rTMS for tobacco craving and cognition using a short-term (3-day) human laboratory paradigm...

Repetitive transcranial magnetic stimulation (rTMS) applied to the left frontal lobe is discussed to be a promising add-on treatment for negative symptoms in schizophrenia. The Positive and Negative Syndrome Scale (PANSS) has been used as outcome parameter in several previous rTMS trials, but studies focusing on PANSS factor analyses are lacking. For this purpose, we used the available PANSS data of the 'rTMS for the Treatment of Negative Symptoms in Schizophrenia' (RESIS) trial to calculate different literature-based PANSS factors and to re-evaluate the impact of rTMS on negative symptoms in this trial...

BACKGROUND: High-frequency left-sided repetitive transcranial magnetic stimulation (rTMS) is now commonly used treatment for patients with depression. However, there are several other forms of rTMS (low-frequency right-sided and sequential bilateral rTMS) which have also been shown to be effective. No information has been systematically gathered on the likelihood of response to alternative forms of rTMS in patients who do not improve after an initial course of left-sided treatment. OBJECTIVE: To evaluate whether there are differences in antidepressant response between switching to either low-frequency right sided or sequential bilateral stimulation or continuing high-frequency left-sided TMS following non-response to an initial course of high-frequency left-sided rTMS...

BACKGROUND: Negative symptoms in schizophrenia concern a clinically relevant reduction of goal-directed behavior that strongly and negatively impacts daily functioning. Existing treatments are of marginal effect and novel approaches are needed. Noninvasive neurostimulation by means of repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) are novel approaches that may hold promise. OBJECTIVES: To provide a quantitative integration of the published evidence regarding effects of rTMS and tDCS over the frontal cortex on negative symptoms, including an analysis of effects of sham stimulation...

Repetitive transcranial magnetic stimulation (rTMS) is increasingly used clinically in the treatment of patients with major depressive disorder (MDD). However, rTMS treatment response can be slow. Early research suggests that accelerated forms of rTMS may be effective but no research has directly evaluated a schedule of accelerated rTMS compared to standard rTMS. To assess the efficacy of accelerated rTMS compared to standard daily rTMS., 115 outpatients with MDD received either accelerated rTMS (n = 58) (i...
