Zrinzo L. Severe Refractory Obsessive Compulsive Disorder and Depression: Should We Consider Stereotactic Neurosurgery? Neuropsychiatr Dis Treat 2024; 20:469-478. [PMID: 38463457 PMCID: PMC10921944 DOI: 10.2147/ndt.s407210] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/16/2023] [Accepted: 02/22/2024] [Indexed: 03/12/2024] Open
Abstract
Functional neurosurgery involves modulation of activity within neural circuits that drive pathological activity. Neurologists and neurosurgeons have worked closely together, advancing the field for over a century, such that neurosurgical procedures for movement disorders are now accepted as "standard of care", benefiting hundreds of thousands of patients. As with movement disorders, some neuropsychiatric illnesses, including obsessive compulsive disorder and depression, can be framed as disorders of neural networks. Over the past two decades, evidence has accumulated that stereotactic neurosurgery can help some patients with mental disorders. Nevertheless, despite the availability of class I evidence for some interventions, there is a huge mismatch between the prevalence of severe refractory mental disorders and the number of referrals made to specialised functional neurosurgery services. This paper examines the historical trajectory of neurosurgery for movement and mental disorders. A review of neurosurgical techniques, including stereotactic radiofrequency ablation, gamma knife, deep brain stimulation, and magnetic resonance imaging guided focused ultrasound, explains the high degree of safety afforded by technological advances in the field. Evidence from clinical trials supporting functional neurosurgery for mental disorders, including obsessive compulsive disorder and depression, is presented. An improved understanding of modern functional neurosurgery should foster collaboration between psychiatry and neurosurgery, providing hope to patients whose symptoms are refractory to all other treatments.

Abstract
Cognitive behavioral therapy (CBT) including exposure and response prevention is a well-established treatment for obsessive-compulsive disorder (OCD) and is based on the principles of fear extinction. Fear extinction is linked to structural and functional variability in the ventromedial prefrontal cortex (vmPFC) and has been consistently associated with glutamate neurotransmission. The relationship between vmPFC glutamate and fear extinction and its effects on CBT outcome have not yet been explored in adults with OCD. We assessed glutamate levels in the vmPFC using 3T magnetic resonance spectroscopy, and fear extinction (learning and recall) using skin conductance responses during a 2-day experimental paradigm in OCD patients (n = 17) and in healthy controls (HC; n = 13). Obsessive-compulsive patients (n = 12) then received manualized CBT. Glutamate in the vmPFC was negatively associated with fear extinction recall and positively associated with CBT outcome (with higher glutamate levels predicting a better outcome) in OCD patients. Glutamate levels in the vmPFC in OCD patients were not significantly different from those in HC, and were not associated with OCD severity. Our results suggest that glutamate in the vmPFC is associated with fear extinction recall and CBT outcome in adult OCD patients.

Curr Med Chem 2019; 25:5647-5661. [PMID: 29278206 DOI: 10.2174/0929867325666171222163645] [Citation(s) in RCA: 44] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2017] [Revised: 10/19/2017] [Accepted: 11/22/2017] [Indexed: 01/04/2023]
Abstract
BACKGROUND Serotonin reuptake inhibitors (SRIs) and cognitive-behavioral psychotherapy (CBT) are first-line treatments for obsessive-compulsive disorder (OCD). However, a significant proportion of patients do not respond satisfactorily to first-choice treatments. Several options have been investigated for the management of resistant patients. OBJECTIVE The aim of the present paper is to systematically review the available literature concerning the strategies for the treatment of resistant adult patients with OCD. METHOD We first reviewed studies concerning the definition of treatment-resistant OCD; we then analyzed results of studies evaluating several different strategies in resistant patients. We limited our review to double-blind, placebo-controlled studies performed in adult patients with OCD whose resistance to a first adequate (in terms of duration and dosage) SRI trial was documented and where outcome was clearly defined in terms of decrease in Yale-Brown Obsessive-Compulsive Scale (YBOCS) scores and/or response/ remission rates (according to the YBOCS). RESULTS We identified five strategies supported by positive results in placebo-controlled randomized studies: 1) antipsychotic addition to SRIs (16 RCTs, of them 10 positive; 4 head-to-head RCTs); among antipsychotics, available RCTs examined the addition of haloperidol (butyrophenone), pimozide (diphenyl-butylpiperidine), risperidone (SDA: serotonin- dopamine antagonist), paliperidone (SDA), olanzapine (MARTA: multi-acting receptor targeted antipsychotic), quetiapine (MARTA) and aripiprazole (partial dopamine agonist); 2) CBT addition to medication (2 positive RCTs); 3) switch to intravenous clomipramine (SRI) administration (2 positive RCTs); 4) switch to paroxetine (SSRI: selective serotonin reuptake inhibitor) or venlafaxine (SNRI: serotonin-norepinephrine reuptake inhibitor) when the first trial was negative (1 positive RCT); and 5) the addition of medications other than an antipsychotic to SRIs (18 RCTs performed with several different compounds, with only 4 positive studies). CONCLUSION Treatment-resistant OCD remains a significant challenge to psychiatrists. To date, the most effective strategy is the addition of antipsychotics (aripiprazole and risperidone) to SRIs; another effective strategy is CBT addition to medications. Other strategies, such as the switch to another first-line treatment or the switch to intravenous administration are promising but need further confirmation in double-blind studies. The addition of medications other than antipsychotics remains to be studied, as several negative studies exist and positive ones need confirmation (only 1 positive study).

Abstract
BACKGROUND Deep brain stimulation (DBS) is an emerging treatment for severe obsessive-compulsive disorder (OCD). We compared the efficacy of ventral capsule/ventral striatal (VC/VS) and anteromedial subthalamic nucleus (amSTN) DBS in the same patients and tested for mechanistic differences on mood and cognitive flexibility and associated neural circuitry. The possible synergistic benefit of DBS at both sites and cognitive behavioral therapy was explored. METHODS Six patients with treatment-refractory OCD (5 men; Yale-Brown Obsessive Compulsive Scale score >32) entered double-blind counterbalanced phases of 12-week amSTN or VC/VS DBS, followed by 12-week open phases when amSTN and VC/VS were stimulated together, in which optimal stimulation parameters were achieved and adjunctive inpatient cognitive behavioral therapy was delivered. OCD and mood were assessed with standardized scales and cognitive flexibility with the Cambridge Neuropsychological Test Automated Battery Intra-Extra Dimensional Set-Shift task. Diffusion-weighted and intraoperative magnetic resonance imaging scans were performed for tractography from optimally activated electrode contacts. RESULTS DBS at each site significantly and equivalently reduced OCD symptoms with little additional gain following combined stimulation. amSTN but not VC/VS DBS significantly improved cognitive flexibility, whereas VC/VS DBS had a greater effect on mood. The VC/VS effective site was within the VC. VC DBS connected primarily to the medial orbitofrontal cortex, and amSTN DBS to the lateral orbitofrontal cortex, dorsal anterior cingulate cortex, and dorsolateral prefrontal cortex. No further improvement followed cognitive behavioral therapy, reflecting a floor effect of DBS on OCD. CONCLUSIONS Both the VC/VS and amSTN are effective targets for severe treatment-refractory OCD. Differential improvements in mood and cognitive flexibility and their associated connectivity suggest that DBS at these sites modulates distinct brain networks.

Abstract
BACKGROUND Oslo University Hospital, Norway, had by autumn 2016, accumulated a waiting list of 101 patients with obsessive-compulsive disorder (OCD) who had a legal right to receive treatment by a specialized OCD team. In this challenging situation, the Bergen OCD-team suggested to solve the problem by offering all patients an option for the rapid Bergen 4-day treatment (B4DT). The B4DT is an individual treatment delivered during four consecutive days in a group of six patients with the same number of therapists. The approach has previously shown a post-treatment response rate of 90% and a 3-month remission rate of 70%. METHODS Ninety-seven of the wait-list patients were available for the scheduled time slots, and 90 received the 4-day format during 8 days (45 patients each week). The therapists were recruited from 22 different specialized OCD-teams from all over Norway, and 44 (68%) had not previously delivered the 4-day format. RESULTS Post-treatment; 91.1% of the patients were classified as responders, and 72.2% were in remission. At 3-month follow-up; 84.4 were classified as responders and the remission rate was 67.7%. Oslo University Hospital now offers the 4-day treatment as standard treatment for OCD. CONCLUSIONS We conclude that the B4DT is an acceptable and potentially effective OCD-treatment.

Abstract
AbstractObsessive-compulsive disorder (OCD) and related disorders such as body dysmorphic disorder (BDD) can take many different forms of presentations. The term ‘complex’ is common and inconsistently used in both OCD and BDD. Practitioners often refer to complex OCD or BDD when patients present with severe co-morbid problems, often in the context of personality difficulties, dissociation, difficult early relationships and trauma; or when the illness is chronic and debilitating with previous multiple treatment failures. Current best-evidence treatment protocols for both disorders focus heavily on exposure and response prevention (E/RP) but with moderate success, particularly in patients who are deemed ‘complex’, and often those with relevant shame and/or disgust-based past experiences. The aim of the present paper is to (a) describe factors that contribute to complexity in OCD and BDD, and (b) link these with theory and practice. We emphasize the importance of understanding both the function of OCD and BDD-related behaviours (rather than the content of obsessions or compulsion), and the context in which they occur such as the family. We illustrate complexity in OCD and BDD using real case material, using a functional and contextual approach to formulate the client's difficulties, and demonstrate how E/RP can be enhanced successfully with imagery rescripting, family work, and compassion-focused therapy.

Abstract
BACKGROUND Cognitive behavioural therapy (CBT), including exposure and ritual prevention, is a first-line treatment for obsessive-compulsive disorder (OCD), but few reliable predictors of CBT outcome have been identified. Based on research in animal models, we hypothesized that individual differences in basolateral amygdala-ventromedial prefrontal cortex (BLA-vmPFC) communication would predict CBT outcome in patients with OCD. METHODS We investigated whether BLA-vmPFC resting-state functional connectivity (rs-fc) predicts CBT outcome in patients with OCD. We assessed BLA-vmPFC rs-fc in patients with OCD on a stable dose of a selective serotonin reuptake inhibitor who then received CBT and in healthy control participants. RESULTS We included 73 patients with OCD and 84 healthy controls in our study. Decreased BLA-vmPFC rs-fc predicted a better CBT outcome in patients with OCD and was also detected in those with OCD compared with healthy participants. Additional analyses revealed that decreased BLA-vmPFC rs-fc uniquely characterized the patients with OCD who responded to CBT. LIMITATIONS We used a sample of convenience, and all patients were receiving pharmacological treatment for OCD. CONCLUSION In this large sample of patients with OCD, BLA-vmPFC functional connectivity predicted CBT outcome. These results suggest that future research should investigate the potential of BLA-vmPFC pathways to inform treatment selection for CBT across patients with OCD and anxiety disorders.

Abstract
The appraisal model of obsessive-compulsive disorder (OCD) suggests that six key appraisal domains contribute to the aetiology and maintenance of OCD symptoms. An accumulating body of evidence supports this notion and suggests that modifying cognitive appraisals may be beneficial in reducing obsessive-compulsive symptomatology. This literature review first summarises the nature of OCD and its treatment, followed by a summary of the existing correlational and experimental research on the role of cognitive appraisal processes in OCD across both adult and paediatric samples. While correlational data provide some support for the relationship between cognitive appraisal domains and OCD symptoms, results are inconclusive, and experimental methods are warranted to determine the precise causal relationship between specific cognitive appraisal domains and OCD symptoms.

Abstract
BACKGROUND AND OBJECTIVES Mental contamination refers to feelings of internal dirtiness that can arise without physical contact with a contaminant. Previous research has demonstrated that contamination-related feelings and subsequent washing behaviours can be evoked by engaging in an imaginal task involving a non-consensual kiss. We sought to test the efficacy of neutralisation behaviours such as washing on experimentally induced mental contamination. METHODS The current study used a female undergraduate sample (N = 80) to act as the perpetrator of an imagined non-consensual kiss of a 14-year old boy, to examine whether mental contamination would be evoked, and whether neutralisation would be effective. RESULTS Mental contamination was successfully evoked in using the imaginal task. None of the neutralisation strategies (physical washing, mental washing, atonement) was more effective than a control group in reducing mental contamination. Groups using physical washing completed the experiment with higher levels of negative emotions than the control group, suggesting specific deleterious impact of this neutralisation behaviour. LIMITATIONS The use of a non-clinical sample, as well as a uniform mental contamination method (rather than one specifically tailored to each participant) are limitations of the current study. CONCLUSIONS Mental contamination is not reduced by a range of neutralisation strategies, and physical washing may have further negative effects such as increased negative emotion.

[PMID: 26366407 PMCID: PMC4561118 DOI: 10.1155/2015/186927] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/13/2015] [Accepted: 07/26/2015] [Indexed: 11/18/2022]
Abstract
Objective. The purpose of this study was to compare the prevalence of comorbid eating disorders in Obsessive-Compulsive Disorder (OCD) and other common anxiety disorders. Method. 179 patients from the same geographical area with a diagnosis of OCD or an anxiety disorder were divided into two groups based on their primary diagnosis. The prevalence of a comorbid eating disorder was calculated in both groups. Results. There was no statistically significant difference in the prevalence of comorbid eating disorders between the OCD and other anxiety disorders group. Conclusions. These results suggest that the prevalence of comorbid eating disorders does not differ in anxiety disorders when compared with OCD. However, in both groups, it remains statistically higher than that of the general population.

Abstract
Disgust is an understudied but important emotion in various psychological disorders. Over the last decade, increasing evidence suggests that disgust is also present in various subtypes of obsessive-compulsive disorder (OCD), especially in contamination-related OCD (C-OCD). The treatment of choice for C-OCD is exposure with response prevention, originally designed to reduce fear-associated emotions thought to be acquired through Pavlovian conditioning (PC). However, disgust has been proposed to be acquired through evaluative conditioning (EC) and according to the referential model of this form of learning, there are functional differences between PC and EC that need to be considered in the treatment of disgust-related responses. Alternative strategies suggested by EC-based models include counterconditioning (contingent presentation of the CS with a US of opposite valence) and US revaluation (contingent presentation of the US with US of opposite valence). Drawing on the referential model, this paper reviews evidence for the effectiveness of each strategy to identify the most theoretically sound and empirically valid intervention to reduce disgust in C-OCD.

Brain regions related to fear extinction in obsessive-compulsive disorder and its relation to exposure therapy outcome: a morphometric study. Psychol Med 2014; 44:845-856.

Abstract
BACKGROUND The size of particular sub-regions within the ventromedial prefrontal cortex (vmPFC) has been associated with fear extinction in humans. Exposure therapy is a form of extinction learning widely used in the treatment of obsessive-compulsive disorder (OCD). Here we investigated the relationship between morphometric measurements of different sub-regions of the vmPFC and exposure therapy outcome in OCD. METHOD A total of 74 OCD patients and 86 healthy controls underwent magnetic resonance imaging (MRI). Cortical thickness and volumetric measurements were obtained for the rostral anterior cingulate cortex (rACC), the medial orbital frontal cortex and the subcallosal cortex. After MRI acquisition, patients were enrolled in an exposure therapy protocol, and we assessed the relationship between MRI-derived measurements and treatment outcome. Baseline between-group differences for such measurements were also assessed. RESULTS Compared with healthy controls, OCD patients showed a thinner left rACC (p = 0.008). Also, left rACC thickness was inversely associated with exposure therapy outcome (r - 0.32, p = 0.008), and this region was significantly thinner in OCD patients who responded to exposure therapy than in those who did not (p = 0.006). Analyses based on regional volumetry did not yield any significant results. CONCLUSIONS OCD patients showed cortical thickness reductions in the left rACC, and these alterations were related to exposure therapy outcome. The precise characterization of neuroimaging predictors of treatment response derived from the study of the brain areas involved in fear extinction may optimize exposure therapy planning in OCD and other anxiety disorders.

Technological advances in psychotherapy: implications for the assessment and treatment of obsessive compulsive disorder. J Anxiety Disord 2013; 27:47-55. [PMID: 23247201 DOI: 10.1016/j.janxdis.2012.09.004] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2012] [Revised: 08/27/2012] [Accepted: 09/17/2012] [Indexed: 11/22/2022]
Abstract
Obsessive compulsive disorder (OCD) is a prevalent and costly condition that causes significant functional impairment and reduced quality of life. Although treatments with demonstrated efficacy for OCD, such as cognitive behavior therapy and antidepressants, have existed for over three decades, many patients remain inadequately treated or untreated. Challenges encountered in the treatment of OCD include problems with homework compliance, frequent relapse, difficulties in simulating the spontaneous nature of intrusive thoughts, and infrequent treatment sessions. Accumulated research now indicates that computerized assessment and therapy tools can significantly improve the cost/time-effectiveness of conventional psychotherapeutic interventions for anxiety disorders such as OCD without impairing therapeutic progress and outcome. In this paper we examine the potential of such technology, address current challenges in the assessment and treatment of OCD, and provide a rationale for future research in the field. We outline the general utility of computer technology in psychotherapeutic interventions, critically evaluate the existing literature on computer-assisted assessment and treatment specific to OCD, as well as discuss potential implications of portable technology for OCD treatment delivery and outcomes.
