Book Description
The 2nd edition of this book incorporates the tremendous clinical advances that have occurred in the field of transcranial direct current stimulation (tDCS) over the past 5 years. Since the 1st edition was published, the clinical use of tDCS has moved from its infancy, and is now in a thrilling new phase with numerous possibilities as well as challenges. tDCS is a technique that excels in terms of safety and tolerability, and within a few years, novel technological developments will allow its use at home. At the same time, large, phase III trials have been exploring the clinical efficacy of tDCS, the results of which have been published in leading journals such as the New England Journal of Medicine and JAMA Psychiatry. This 2nd edition summarizes the state of the art of the field. Written by leading experts in the field, the book is divided into 5 parts: Introduction and Mechanisms of Action; Research Methods; tDCS in the life cycle; Applications of tDCS in neuropsychiatric disorders (further divided into Psychiatry and Neurology); and The clinical use of tDCS. It also includes several new chapters, covering topics such as precision stimulation of tDCS; combination of tDCS with different neuroimaging modalities; and use of tDCS in new clinical conditions. Moreover, all chapters have been rewritten and updated. This book will be of significant interest to psychiatrists, neurologists and neuroscientists new to the field as well as those with a background in tDCS who want to increase their understanding of particular psychiatric conditions.

Book Description
The aim of this book is to provide a comprehensive review of the use of Transcranial Direct Current Stimulation (tDCS) in different psychiatric conditions. Here we review tDCS clinical studies employing different types of design (from single-session tDCS studies to randomized clinical trials) as well as studies evaluating the impact of tDCS in neurophysiological, behavioral and brain imaging outcomes. Although the understanding about physiological foundations and effectiveness of clinical therapies of psychiatric diseases has been considerably increased during the last decades, our knowledge is still limited, and consequently psychiatric diseases are still a major burden to the individual patient and society. Recently, interest in pathological alterations of neuroplasticity in psychiatric diseases as a critical condition for development, and amelioration of clinical symptoms increased, caused by the fact that new tools, such as functional imaging, and brain stimulation techniques do allow to monitor, and modulate these phenomena in humans. Especially non-invasive brain stimulation techniques evolved as an attractive potential new therapeutic tool. The interest in non-invasive brain stimulation has grown exponentially in the past 25 years, with the development of non-pharmacological, neuromodulatory techniques such as tDCS and repetitive transcranial magnetic stimulation (rTMS). TDCS, although even newer than rTMS, has attracted considerable attention in both basic and clinical research scenarios. In the context of clinical research, tDCS is being increasingly investigated as a novel treatment tool for several psychiatric disorders, such as major depression, schizophrenia and neurocognitive and substance abuse disorders. Transcranial Direct Current Stimulation in Neuropsychiatric Disorders – Clinical Principles and Management intends to serve as a practical guide on the field, attracting the interest of psychiatrists, neurologists and neuroscientists with little or no experience with tDCS, as well as those with a background on tDCS who want to increase their knowledge in any particular psychiatric condition.

Book Description
Transcranial brain stimulation has received an increased interest among the scientific community due its capability to modulate cortical excitability, which in turn modifies brain functions resulting in neuroplastic changes. In particular, transcranial direct current stimulation (tDCS) has been widely explored for its clinical efficacy, safety, painlessness, portability, ease of application, low cost, well-tolerated among patients, and positive clinical results seen within a few weeks. This noninvasive brain therapy has been used as an adjuvant tool for treating neurological and psychiatric diseases such as chronic pain, depression, obesity, memory and others. The basic principle of tDCS is modulating cerebral functions through applying a weak and direct electric current over the target cortical area. The first chapter of this book provides current research on tDCS and neuroplasticity. Chapter Two provides definitions of dosimetry from both safety and efficacy standpoints and proposes 14 guidelines for safe and effective application of tDCS. Chapter Three examines the use of tDCS and other rehabilitation techniques for patients to improve upper limb motor function after suffering from a stroke. The final chapter studies the effects of cathodal transcranial direct stimulation on epileptic patients.

Book Description
Transcranial magnetic stimulation (TMS) was introduced in the mid 1980s in clinical neurophysiology to study the central motor pathways. Research has been exponentially increased since, and many different methods for brain stimulation have been considered during the last decade. This publication focuses on transcranially applied, non- or low-invasive interventions not requiring an implantable device, i.e. electroconvulsive therapy (ECT), repetitive TMS (rTMS) and transcranial direct current stimulation (tDCS). It provides an excellent overview on this spectrum of fascinating techniques. Many leading experts in this field have contributed to this book. A single chapter summarizes the state of the art in ECT. A series of chapters provides an overview on preclinical research in animals and neuroimaging findings with rTMS and reviews the evidence of efficacy and safety in various psychiatric disorders (affective disorders, schizophrenia and anxiety disorders) also including an article on the application of rTMS in nonpsychiatric diseases, i.e. Parkinson's disease, stroke, pain and tinnitus. Finally, separate reviews discuss very recent innovative approaches in the field of rTMS, i.e. magnetic seizure therapy, theta burst stimulation and deep rTMS. This publication will doubtlessly prove to be essential reading not only to researchers in this field, but also to psychiatrists, neurologists and other clinicians who consider applying these new methods in clinical settings

Book Description
Transcranial magnectic stimulation (TMS) is a neurological technique for inducing motor movement by direct magnetic stimulation of the brain's motor cortex-while the subject is awake and alert-to measure connectivity and excitability. It depends on the principle of mutual induction (discovered by Michael Faraday in 1831), whereby electrical energy can be converted into magnetic fields, and magnetic fields can be converted into electrical energy. The ability to measure the excitability of the motor cortex in important in neuropsychiatry for several reasons: 1) TMS may prove valuable as a diagnostic tool, because there is increasing evidence of altered motor cortex excitability in several neuropsychiatric disorders. 2) Stimulus parameters (especially stimulus intensity) must be adjusted to the patient's individual motor excitability in repetitive TMS (rTMS) treatment protocols. Therefore, the knowledge of how to measure motor cortex excitability is indispensable. 3) Evidence shows that various rTMS protocols can increase or decrease cortical excitability and thus can be used therapeutically to normalize altered excitability in neuropsychiatry diseases. How did TMS evolve into the techniques used today? How does it fit into the localization debate (the idea that physiological functions are organized into discrete brain regions), now reenergized by the advent of modern neuroimaging tools (PET, SPECT, and MRI)? How does it differ from ECT? For what disorders is TMS effective, and how is this effectiveness measured? What safety concerns are involved? Where is future research headed? For the answers to these questions, readers can now turn to a single source, "Transcranial MagneticStimulation in Neuropsychiatry," In these fascinating chapters rich with illustrations, current clinical researchers describe how-thanks to TMS-they now have elaborate roadmaps of the brain regions putatively involved in specific disorders including movement disorders, epilepsy, major depression, bipolar disorder/mania, anxiety disorders, developmental stuttering and Tourette's syndrome, and schizophrenia. Even with advances in neuroimaging science, much of the adult human brain remains a mystery. "Transcranial Magnetic Stimulation in Neuropsychiatry" helps shed light on the astonishing intricacies of brain function and organization, and as such is a must-read for anyone interested in how the brain works-clinical researchers of brain function, neuroscientists, neurologists, general psychiatrists, neuropsychiatrists, psychologists, and social workers.

Book Description
The potential efficacy of non-invasive brain stimulation procedures for the management of specific symptoms in diverse neurological and psychiatric conditions has been tested in the past decade or so. For example, repetitive transcranial magnetic stimulation (rTMS) over prefrontal areas has been extensively investigated as a treatment for patients with medication-resistant depression and has been shown to be associated with improvement of mood. Similarly, non-invasive stimulation techniques have been applied to various symptoms of Parkinson's disease such as bradykinesia and dyskinesias, with variables degrees of success reported. However, attempts to expand previously observed clinical improvements to other neurological disorders (e.g. Tourette's syndrome, autism, epilepsy) has been controversial. In trying to bypass potential confounding elements, researchers aim to target neural populations altered in disease to either increase or decrease their corrupted baseline activity. In addition, a complementary approach is to extend stimulation protocols that results enhanced behavior in healthy participants. This Frontiers Research Topic on non-invasive brain stimulation and enhancement of function tries to combine a series of articles from researchers who used non-invasive brain stimulation to aim improvement of either a motoric, cognitive or behavioral nature investigated behaviorally, physiologically or using brain imaging techniques in clinical populations. Investigation of the relation between enhancement of function in healthy populations and clinical improvement in patients with neurological or psychiatric disorders needs further consideration.

Book Description
Abstract: Transcranial direct current stimulation (tDCS) is increasingly used as a form of noninvasive brain stimulation to treat psychiatric disorders; however, its mechanism of action remains unclear. Prolonged visual stimulation (PVS) can enhance evoked EEG potentials (visually evoked potentials, VEPs) and has been proposed as a tool to examine long-term potentiation (LTP) in humans. The objective of the current study was to induce and analyze VEP plasticity and examine whether tDCS could either modulate or mimic plasticity changes induced by PVS. Thirty-eight healthy participants received tDCS, PVS, either treatment combined or neither treatment, with stimulation sessions being separated by one week. One session consisted of a baseline VEP measurement, one stimulation block, and six test VEP measurements. For PVS, a checkerboard reversal pattern was presented, and for tDCS, a constant current of 1 mA was applied via each bioccipital anodal target electrode for 10 min (Fig. S1). Both stimulation types decreased amplitudes of C1 compared to no stimulation (F = 10.1; p = 0.002) and led to a significantly smaller increase (PVS) or even decrease (tDCS) in N1 compared to no stimulation (F = 4.7; p = 0.034). While all stimulation types increased P1 amplitudes, the linear mixed effects model did not detect a significant difference between active stimulation and no stimulation. Combined stimulation induced sustained plastic modulation of C1 and N1 but with a smaller effect size than what would be expected for an additive effect. The results demonstrate that tDCS can directly induce LTP-like plasticity in the human cortex and suggest a mechanism of action of tDCS relying on the restoration of dysregulated synaptic plasticity in psychiatric disorders such as depression and schizophrenia
