    Gamma knife capsulotomy for intractable OCD: Neuroimage analysis of lesion size, location, and clinical response
    (2023) MCLAUGHLIN, N. C. R.; MAGNOTTI, J. F.; BANKS, G. P.; NANDA, P.; HOEXTER, M. Q.; LOPES, A. C.; BATISTUZZO, M. C.; ASAAD, W. F.; STEWART, C.; PAULO, D.; NOREN, G.; GREENBERG, B.

    Obsessive-compulsive disorder (OCD) affects 2-3% of the population. One-third of patients are poorly responsive to conventional therapies, and for a subgroup, gamma knife capsulotomy (GKC) is an option. We examined lesion characteristics in patients previously treated with GKC through well-established programs in Providence, RI (Butler Hospital/Rhode Island Hospital/Alpert Medical School of Brown University) and Sao Paulo, Brazil (University of Sao Paolo). Lesions were traced on T1 images from 26 patients who had received GKC targeting the ventral half of the anterior limb of the internal capsule (ALIC), and the masks were transformed into MNI space. Voxel-wise lesion-symptom mapping was performed to assess the influence of lesion location on Y-BOCS ratings. General linear models were built to compare the relationship between lesion size/location along different axes of the ALIC and above or below-average change in Y-BOCS ratings. Sixty-nine percent of this sample were full responders (>= 35% improvement in OCD). Lesion occurrence anywhere within the targeted region was associated with clinical improvement, but modeling results demonstrated that lesions occurring posteriorly (closer to the anterior commissure) and dorsally (closer to the mid-ALIC) were associated with the greatest Y-BOCS reduction. No association was found between Y-BOCS reduction and overall lesion volume. GKC remains an effective treatment for refractory OCD. Our data suggest that continuing to target the bottom half of the ALIC in the coronal plane is likely to provide the dorsal-ventral height required to achieve optimal outcomes, as it will cover the white matter pathways relevant to change. Further analysis of individual variability will be essential for improving targeting and clinical outcomes, and potentially further reducing the lesion size necessary for beneficial outcomes.

    Spatial normalization discrepancies between native and MNI152 brain template scans in gamma ventral capsulotomy patients
    (2023) GIFF, Alexis; NOREN, Georg; MAGNOTTI, John; LOPES, Antonio Carlos; BATISTUZZO, Marcelo Camargo; HOEXTER, Marcelo; GREENBERG, Benjamin; MARSLAND, Richard; MIGUEL, Euripedes Constantino; RASMUSSEN, Steven; MCLAUGHLIN, Nicole
    In neurosurgery, spatial normalization emerged as a tool to minimize inter-subject variability and study target point locations based on standard coordinates. The Montreal Neurological Institute's 152 brain template (MNI152) has become the most widely utilized in neuroimaging studies, but has been noted to introduce partial volume effects, distortions, and increase structure size in all directions (x/y/z axes). These discrepancies question the accuracy of the MNI template, as well as its utility for studies that examine and form conclusions from group -level data. Given that surgical precision in obsessive-compulsive disorder is essential to patient outcomes, we retrospectively investigated lesion size and location in patients (n = 21) who underwent capsulotomy for intractable OCD, comparing deviations in the native scans to those in standard space. MNI measurements were significantly larger than native measurements across several structures in both coronal and axial slices, and we found that MNI transformation increases the size of many subcortical structures in a significant and proportional way for both females and males. These findings urge caution when using MNI as a reference space, as well as a stronger consideration of population-specific brain templates when examining connectivity-based networks.

    Brazilian Research Consortium on Obsessive-Compulsive Spectrum Disorders guidelines for the treatment of adult obsessive-compulsive disorder. Part I: pharmacological treatment
    (2023) OLIVEIRA, Marcos Vinicius Sousa de; BARROS, Pedro Macul Ferreira de; MATHIS, Maria Alice de; BOAVISTA, Rodrigo; CHACON, Priscila; ECHEVARRIA, Marco Antonio Nocito; FERRAO, Ygor Arzeno; VATTIMO, Edoardo Felippo de Queiroz; LOPES, Antonio Carlos; TORRES, Albina Rodrigues; DINIZ, Juliana Belo; FONTENELLE, Leonardo F.; ROSARIO, Maria Conceicao do; SHAVITT, Roseli Gedanke; MIGUEL, Euripedes Constantino; SILVA, Renata de Melo Felipe da; COSTA, Daniel Lucas da Conceiao
    Objectives: To summarize evidence-based pharmacological treatments and provide guidance on clinical interventions for adult patients with obsessive-compulsive disorder (OCD).Methods: The American Psychiatric Association (APA) guidelines for the treatment of OCD (2013) were updated with a systematic review assessing the efficacy of pharmacological treatments for adult OCD, comprising monotherapy with selective serotonin reuptake inhibitors (SSRIs), clomipramine, serotonin and norepinephrine reuptake inhibitors (SNRIs), and augmentation strategies with clomipramine, antipsychotics, and glutamate-modulating agents. We searched for the literature published from 2013-2020 in five databases, considering the design of the study, primary outcome measures, types of publication, and language. Selected articles had their quality assessed with validated tools. Treatment recommendations were classified according to levels of evidence developed by the American College of Cardiology and the American Heart Association (ACC/AHA). Results: We examined 57 new studies to update the 2013 APA guidelines. High-quality evidence supports SSRIs for first-line pharmacological treatment of OCD. Moreover, augmentation of SSRIs with antipsychotics (risperidone, aripiprazole) is the most evidence-based pharmacological interven-tion for SSRI-resistant OCD. Conclusion: SSRIs, in the highest recommended or tolerable doses for 8-12 weeks, remain the first -line treatment for adult OCD. Optimal augmentation strategies for SSRI-resistant OCD include low doses of risperidone or aripiprazole. Pharmacological treatments considered ineffective or potentially harmful, such as monotherapy with antipsychotics or augmentation with ketamine, lamotrigine, or N-acetylcysteine, have also been detailed.

    Brazilian Research Consortium on Obsessive-Compulsive Spectrum Disorders guidelines for the treatment of adult obsessive-compulsive disorder. Part II: cognitive-behavioral therapy
    (2023) MATHIS, Maria Alice de; CHACON, Priscila; BOAVISTA, Rodrigo; OLIVEIRA, Marcos Vinicius Sousa de; BARROS, Pedro Macul Ferreira de; ECHEVARRIA, Marco Antonio Nocito; FERRAO, Ygor Arzeno; VATTIMO, Edoardo Filippo de Queiroz; LOPES, Antonio Carlos; TORRES, Albina Rodrigues; DINIZ, Juliana Belo; FONTENELLE, Leonardo; ROSARIO, Maria Conceicao do; SHAVITT, Roseli Gedanke; SILVA, Renata de Melo Felipe da; CONSTANTINO, Euripedes; COSTA, Daniel Lucas da Conceicao
    Objectives: To summarize evidence-based cognitive-behavioral therapy (CBT) treatment and propose clinical interventions for adult patients with obsessive-compulsive disorder (OCD).Methods: The literature on CBT interventions for adult OCD, including BT and exposure and response prevention, was systematically reviewed to develop updated clinical guidelines for clinicians, providing comprehensive details about the necessary procedures for the CBT protocol. We searched the literature from 2013-2020 in five databases (PubMed, Cochrane, Embase, PsycINFO, and Lilacs) regarding study design, primary outcome measures, publication type, and language. Selected articles were assessed for quality with validated tools. Treatment recommendations were classified according to levels of evidence developed by the American College of Cardiology and the American Heart Association.Results: We examined 44 new studies used to update the 2013 American Psychiatric Association guidelines. High-quality evidence supports CBT with exposure and response prevention techniques as a first-line treatment for OCD. Protocols for Internet-delivered CBT have also proven efficacious for adults with OCD.Conclusion: High-quality scientific evidence supports the use of CBT with exposure and response prevention to treat adults with OCD.
