BACKGROUND: Deep transcranial magnetic stimulation (dTMS) has been sanctioned by the United States Food and Drug Administration for treatment-resistant depression. In a retrospective cohort study, we evaluated response and effectiveness of dTMS in real-world practice, as an add-on treatment for resistant depression. METHODS: Forty adult outpatients suffering from depression, all taking psychiatric medications, underwent 20 dTMS treatments over a 4-6 week period...

Major depressive disorder (MDD) affects 3 to 17 % of adults. 15 to 30 % of patients with MDD suffer from treatment resistant depression (TRD). No international consensus defines TRD. The most common definition is " MDD that is not enough improved after two successive and different classes of antidepressant treatments in appropriate dose and duration ". The appropriate dose corresponds to maximal dose accepted by scientific reports and clinical recommendations, while the appropriate duration is around 6 weeks...

Freezing of Gait (FOG) is one of the most debilitating gait impairments in Parkinson's disease (PD), leading to increased fall risk and reduced health-related quality of life. The utility of parkinsonian medications is often limited in the case of FOG and it frequently becomes dopamine resistant. Recent studies have suggested that pre-frontal cortex (PFC) dysfunction contributes to FOG; however, most previous findings provide only indirect evidence. To better understand the role of the PFC, we aimed to investigate the impact of high frequency, deep, repetitive transcranial magnetic stimulation (drTMS) of the medial PFC on FOG and its mediators...

Corticostriatal circuits through the orbitofrontal cortex (OFC) play key roles in complex human behaviors such as evaluation, affect regulation and reward-based decision-making. Importantly, the medial and lateral OFC (mOFC and lOFC) circuits have functionally and anatomically distinct connectivity profiles which differentially contribute to the various aspects of goal-directed behavior. OFC corticostriatal circuits have been consistently implicated across a wide range of psychiatric disorders, including major depressive disorder (MDD), obsessive compulsive disorder (OCD), and substance use disorders (SUDs)...

Sleep and epilepsy are mutually related in a complex, bidirectional manner. However, our understanding of this relationship remains unclear. In this paper, we address the issues involved in these phenomena and also discuss the various therapies used to modify them. The literatures of the neurobiological basis of the interactions between sleep and epilepsy indicate that non-rapid eye movement sleep and idiopathic generalized epilepsy share the same thalamocortical networks. Neuromodulators-such as adenosine, melatonin, prostaglandin D2, serotonin, and histamine-promote wakefulness and are considered to have antiepilepsy effects; antiepileptic drugs, in turn, also have effects on sleep...

Obsessive-Compulsive Disorder (OCD) is a highly disabling condition with early onset and chronic course in most of the affected patients. In addition, OCD may show high comorbidity and suicide attempt rates, which worsen the overall burden of the disease for patients and their caregivers. First-line treatments for OCD consist of pro-serotonergic compounds and cognitive-behavioral therapy. Nonetheless, many patients show only limited benefit from such interventions and require additional "next-step" interventions, including augmentative antipsychotics and glutamate-modulating agents...

Repetitive Transcranial Magnetic Stimulation (rTMS) of the dorsolateral prefrontal cortex may affect neuro-adaptations associated with alcohol use disorder (AUD), potentially influencing craving and alcohol intake. We investigated alcohol intake and dopamine transporter (DAT) availability by Single Photon Emission Computed Tomography (SPECT) in the striatum of AUD patients before and after deep rTMS. Fourteen patients underwent baseline clinical and SPECT assessment. Eleven out of fourteen patients were randomized into two groups for the REAL (n...

BACKGROUND: An acute course of dTMS typically involves treatments delivered 5 days a week, for 4 weeks. Should more treatments be given if the patient has not responded? Data are needed to inform decisions about the best next steps for acute non-responders. OBJECTIVE: To characterize response among acute-phase non-responders in a randomized controlled trial of deep repetitive transcranial magnetic stimulation (dTMS) monotherapy for medication-resistant depression...

Understanding the brain circuitry that underlies reward is critical to improve treatment for many common health issues, including obesity, depression, and addiction. Here we focus on insights into the organization and function of reward circuitry and its synaptic and structural adaptations in response to cocaine exposure. While the importance of certain circuits, such as the mesocorticolimbic dopamine pathway, are well established in drug reward, recent studies using genetics-based tools have revealed functional changes throughout the reward circuitry that contribute to different facets of addiction, such as relapse and craving...

Transcranial magnetic motor evoked potentials (TMMEPs) can assess the functional integrity of the spinal cord descending motor pathways. In intervertebral disc herniation (IVDH), these pathways are compromised to varying degrees reflected by the severity of neurological deficits. The hypotheses of this study were as follows: (1) TMMEPs differ in dogs with IVDH and healthy control dogs; (2) TMMEPs reflect different severities of neurological signs; and (3) TMMEPs can document functional motor improvement and therefore monitor recovery of function...

PURPOSE OF REVIEW: There is growing interest in neuromodulation for primary headache conditions. Invasive modalities such as occipital nerve stimulation, deep brain stimulation and sphenopalatine ganglion stimulation are reserved for the most severe and intractable patients. Non-invasive options such as vagal nerve stimulation (nVNS), supraorbital nerve stimulation (nSONS) and transcranial magnetic nerve stimulation (TMS) have all emerged as potentially useful headache treatments. This review examines the evidence base for non-invasive neuromodulation in trigeminal autonomic cephalalgias and migraine...

Levodopa-induced dyskinesia (LID) represents a severe adverse effect of long-term treatment of Parkinson's disease with levodopa. Neuroimaging studies have contributed to our understanding of LID and may help to identify patients at risk of developing LID. Amantadine can be used for the treatment of LID, and novel drugs are under development. Deep brain stimulation of the subthalamic nucleus and globus pallidus internus alleviates LID, the former indirectly by reducing levodopa intake, the latter through direct effects...

Nonpharmacological treatment strategies in Parkinson' disease include heterogeneous treatment modalities, such as physiotherapy, occupational therapy, speech therapy, cognitive training and deep brain stimulation as well as noninvasive brain stimulation strategies. Even in the early stages of Parkinson's disease nonpharmacological interventions, such as active exercise therapy and speech therapy can be indicated taking the individual symptoms of a patient into account. Mild cognitive deficits are frequently detected in the course of the disease and progression of these disorders to dementia in the advanced stages of the disease is not uncommon...

Literature studies showed the ability to treat neuropsychiatric disorders using H1 coil, developed for the deep Transcranial Magnetic Stimulation (dTMS). Despite the positive results of the clinical studies, the electric field (E) distributions inside the brain induced by this coil when it is positioned on the scalp according to the clinical studies themselves are not yet precisely estimated. This study aims to characterize the E distributions due to the H1 coil in the brain of two realistic human models by computational electromagnetic techniques and to compare them with the ones due to the figure-of-8 coil, traditionally used in TMS and positioned as such to simulate the clinical experiments...

OBJECTIVES: Muscular targets that are deep or inaccessible to surface electromyography (sEMG) require intrinsic recording using fine-wire electromyography (fEMG). It is unknown if fEMG validly record cortically evoked muscle responses compared to sEMG. The purpose of this investigation was to establish the validity and agreement of fEMG compared to sEMG to quantify typical transcranial magnetic stimulation (TMS) measures pre and post repetitive TMS (rTMS). The hypotheses were that fEMG would demonstrate excellent validity and agreement compared with sEMG...

Traumatic spinal cord injury (SCI) is a devastating neurological condition characterized by a constellation of symptoms including paralysis, paraesthesia, pain, cardiovascular, bladder, bowel and sexual dysfunction. Current treatment for SCI involves acute resuscitation, aggressive rehabilitation and symptomatic treatment for complications. Despite the progress in scientific understanding, regenerative therapies are lacking. In this review, we outline the current state and future potential of invasive and non-invasive neuromodulation strategies including deep brain stimulation (DBS), spinal cord stimulation (SCS), motor cortex stimulation (MCS), transcutaneous direct current stimulation (tDCS) and repetitive transcranial magnetic stimulation (rTMS) in the context of SCI...

OBJECTIVE Electrical motor cortex stimulation can relieve neuropathic pain (NP), but its use requires patients to undergo an invasive procedure. Repetitive transcranial magnetic stimulation (rTMS) of the primary motor cortex (M1) using a figure-8 coil can relieve NP noninvasively, but its ability to relieve lower limb pain is still limited. Deep rTMS using an H-coil can effectively stimulate deep brain regions and has been widely used for the treatment of various neurological diseases; however, there have been no clinical studies comparing the effectiveness of figure-8 coils and H-coils...

Bipolar depression (BD) is a highly prevalent condition with limited therapeutic options. Deep (H1-coil) transcranial magnetic stimulation (dTMS) is a novel TMS modality with established efficacy for unipolar depression. We conducted a randomized sham-controlled trial to evaluate the efficacy and safety of dTMS in treatment-resistant BD patients. Patients received 20 sessions of active or sham dTMS over the left dorsolateral prefrontal cortex (H1-coil, 55 18 Hz 2-sec 120% MT trains). The primary outcome was changes in the 17-item Hamilton Depression Rating Scale (HDRS-17) from baseline to endpoint (week 4)...
