Transcranial Direct Current Stimulation in Obsessive-Compulsive Disorder, Posttraumatic Stress Disorder, and Anxiety Disorders.

Obsessive-compulsive disorder (OCD), posttraumatic stress disorder (PTSD), and anxiety disorders share the basic clinical feature of anxiety, which probably explains their common response to similar pharmacological and psychological interventions. Transcranial direct current stimulation (tDCS) is a neuromodulation technique that has proved effective in reducing the symptoms of a number of neuropsychiatric disorders. It was also used in healthy subjects to modulate neuropsychological processes that are involved in the pathophysiology of anxiety. We review the published studies in which tDCS was administered to patients with OCD, PTSD, or anxiety disorders. Our systematic search in the major electronic databases resulted in 14 articles for OCD, 1 for an OCD-related disorder (ie, hoarding disorder), 2 for PTSD, and 2 for anxiety disorders. In the studies involving OCD patients, tDCS was targeted to either the dorsolateral prefrontal cortex or the orbitofrontal cortex or the pre-supplementary motor area and induced a clear reduction of obsessive-compulsive symptoms. However, the lack of sham control groups and the great diversity in sample selection and tDCS protocols among studies prevent us from generalizing these results. In the studies involving PTSD and anxiety disorders patients, tDCS was applied over the dorsolateral prefrontal cortex and reduced symptoms, but the number of treated patients is too little to draw any conclusion on efficacy. However, these reports highlighted the importance of combining tDCS with different procedures, including computerized tasks and behavioral paradigms. In conclusion, even in its infancy, the use of tDCS for the treatment of OCD, PTSD, and anxiety disorders does show promise and deserves extensive research effort.

The Psychiatric Neuromodulation Unit: Implementation and Management.

The proven effectiveness of neuromodulation and stimulation techniques for the management of psychiatric disorders has brought strongly needed innovation in psychiatry, given the high prevalence and high costs of treatment resistance. Although evidence-based guidelines in neuromodulation have been implemented to improve the clinical efficacy, safety, and research procedures, practical suggestions on how to design a psychiatric neuromodulation unit (PNU) are not available in the scientific literature. In this contribution, we have combined the results of a literature search with the suggestions of clinical psychiatrists, managers, and bioethicists who have had firsthand experience in building a PNU. Eleven key issues concerning the implementation and management of a PNU were identified: general context, team composition, environment, basic technical equipment, clinical versus research activities, target clinical population, education and training, interdisciplinarity, ethical aspects, regulatory and reimbursement issues, fund-raising, and partnership development. Moreover, a business plan comprising pragmatic solutions and recommendations for designing an efficient PNU was laid out.

Electroconvulsive Therapy in Italy: Will Public Controversies Ever Stop?

BACKGROUND: The use of electroconvulsive therapy (ECT) is still very limited in Italy for ideological rather than scientific reasons. OBJECTIVES: To describe the public controversies surrounding ECT in Italy and to propose a plan of action to resolve the dispute. METHODS: We describe the historical background and the current public controversies about ECT by reviewing the official documents issued by the entities involved in the debate and by reporting our personal experiences of ECT practice. RESULTS: According to the highest legal and health authorities, there are no ethical reasons for doubting the licit nature of ECT. However, because of politically and ideologically based conflicts, public ECT centers are still lacking. The situation could further deteriorate because local initiatives are endeavoring to criminalize and ban the treatment. CONCLUSIONS: The enactment of specific regulations and guidelines concerning the use of ECT by the Italian government is highly warranted to increase the availability of the treatment. Education and information campaigns must strive to increase the knowledge of health professionals and the lay public regarding the safe and beneficial use of ECT.
