Characteristics of patients who received deep brain stimulation in obsessive-compulsive disorder versus major depressive disorder

Considerations for the treatment of obsessive-compulsive disorder in patients who have comorbid major depression

INTRODUCTION

Obsessive-compulsive disorder (OCD) is a debilitating psychiatric disorder that affects a significant number of individuals worldwide. Major depressive disorder (MDD) is among the most common comorbidities reported in people with OCD. The emergence of MDD in individuals with OCD can be attributed to the increased severity of OCD symptoms and their profound impact on daily functioning. Depressive symptoms can also modify the course of OCD.

AREAS COVERED

In this review, the authors explore potential shared neurobiological mechanisms that may underlie both OCD and MDD, such as disturbed sleep patterns, immunological dysregulations, and neuroendocrine changes. Furthermore, they address the challenges clinicians face when managing comorbid OCD and MDD. The authors also discuss a range of treatment options for OCD associated with MDD, including augmentation strategies for serotonin reuptake inhibitors (e.g. aripiprazole), psychotherapy (especially CBT/EPR), transcranial magnetic stimulation (TMS), electroconvulsive therapy (ECT), and deep brain stimulation (DBS).

EXPERT OPINION

Although there is no 'rule of thumb' or universally acceptable strategy in the treatment of OCD comorbid with MDD, many clinicians, including the authors, tend to adopt a unique transdiagnostic approach to the treatment of OCD and related disorders, focusing on strategies known to be effective across diagnoses. Nevertheless, the existing 'cisdiagnostic approaches' still retain importance, i.e. specific therapeutic strategies tailored for more severe forms of individual disorders.

"They Are Invasive in Different Ways.": Stakeholders' Perceptions of the Invasiveness of Psychiatric Electroceutical Interventions

Medical interventions are usually categorized as "invasive" when they involve piercing the skin or inserting an object into the body. Beyond this standard definition, however, there is little discussion of the concept of invasiveness in the medical literature, despite evidence that the term is used in ways that do not reflect the standard definition of medical invasiveness. We interviewed psychiatrists, patients with depression, and members of the public without depression to better understand their views on the invasiveness of several psychiatric electroceutical interventions (treatments that involve electrical or magnetic stimulation of the brain) for the treatment of depression. Our study shows that people recognize several kinds of invasiveness: physical, emotional, and lifestyle. In addition, several characteristics of therapies influence how invasive they are perceived to be; these include the perceived capacity of an intervention to result in harm; how localized the effects of the intervention are; the amount of control retained by the person receiving the intervention; how permanent its effects are perceived as being; and how familiar it seemed to participants. Our findings contribute to a small literature on the concept of invasiveness, which emphasizes that categorizing an intervention as invasive, or as noninvasive, evokes a variety of other normative considerations, including the potential harm it poses and how it compares to other potential therapies. It may also draw attention away from other salient features of the intervention.
