Preface Modern neuropsychopharmacology has led to important insights into the pathophysiology of mental disorders and the development of effective drugs since the 1950s. More recently, findings derived from functional neuroimaging studies have emphasized the neuroanatomical perspective in mental disorders. This is directly linked to the idea of focally stimulating distinct brain regions in order to exert therapeutic effects. Many different brain stimulation approaches have been considered during the last decades and some of them have been developed into effective therapeutic interventions. Electroconvulsive therapy (ECT), for example, is a wellestablished treatment for depression and catatonia, and deep brain stimulation (DBS) is widely applied in patients suffering from severe Parkinson s disease. Many of these methods converge in terms of underlying mechanisms of action based on fundamental principles of brain function. Sometimes they even show common neurobiological effects, demonstrated by functional neuroimaging, neurophysiology methods and molecular neuroscience techniques. One example are the effects of antidepressant interventions on regional cerebral activity demonstrated by functional neuroimaging: antidepressant drugs and ECT as well as DBS of the subgenual cingulate cortex, which has most recently been investigated [Mayberg et al., 2005], act in a similar manner on dysfunctional regional brain activity in depression, i.e. modulating limbic and paralimbic brain activity in rest towards a state normally observed in healthy volunteers and associated with mental health. However, it is often difficult or impossible to identify the key mechanisms of action and to distinguish them from epiphenomena VII

purely associated with the recovery from disease, but not related to a specific action of an intervention. The different brain stimulation methods can principally be distinguished by specific characteristics. (1) They act on neuronal circuits through various neuroanatomic windows. In some interventions these windows can be defined in terms of neuroanatomic structures as in vagal nerve stimulation (VNS), DBS or repetitive transcranial magnetic stimulation (rtms), and in some interventions the action on the brain is not focal at all as in ECT, magnetic seizure therapy (MST) and transcranial direct current stimulation (tdcs). (2) The methods range in terms of their invasiveness from practically noninvasive approaches (rtms, tdcs), to ECT and MST, which provoke an epileptic seizure, require general anesthesia and may somehow be regarded as more invasive than rtms and tdcs, to clearly invasive techniques (VNS and DBS) where stimulation electrodes and a neurostimulator are implanted. (3) Finally, they differ in terms of the duration of the intervention, i.e. ECT, rtms, MST and tdcs represent acute treatments normally applied over several weeks and rarely extended towards maintenance treatment, whereas VNS and DBS work through a permanent stimulator and are per se long-term treatment strategies, particularly suitable for chronic or frequently relapsing disorders. Our book focuses on transcranially applied, non- or low-invasive interventions not requiring surgery, i.e. ECT, rtms, MST and tdcs. Recent progress in this field has prompted us to edit this book in order to provide an overview on this spectrum of fascinating techniques not only for scientists, but also for clinicians who are interested in these methods and who may even consider applying one or the other approach for the treatment of their patients. However, it is important to emphasize that the different methods are at different stages of development in specific disorders. To reflect this range, the book contains a state-of-the-art chapter on ECT, which still represents a kind of gold standard in this field. It reviews more recent methods, particularly rtms, which is just about to become clinically applicable as treatment for several mental disorders and introduces the most recent achievements: MST, tdcs and two novel variants of rtms, i.e. theta burst stimulation and deep rtms. The latter chapters do not present ready-to-use approaches, but are thought to stimulate a wider interest in methodology and trigger a substantial discussion about options for method development which is clearly needed in this field. We are extremely grateful to our colleagues who have spent their valuable time writing for this book, despite the large number of publication duties a scientist faces in our times. All authors have contributed to the benefit of our readers. Moreover, we thank the staff of S. Karger AG, Basel for their Preface VIII

excellent, accurate and speedy work during the editorial process. Finally, we particularly acknowledge the initiative and the input of the series editors (K.P. Ebmeier, W.P. Kaschka, D. Ebert and W.F. Gattaz) who made this book possible.
