Quantitative Expression of Latent Disease Factors in Individuals Associated with Psychopathology Dimensions and Treatment Response

<p>This repository&nbsp;contains preprocessed resting-state fMRI data&nbsp;including&nbsp;two datasets of obsessive-compulsive disorder (OCD): patients in baseline and&nbsp;patients with capsulotomy.&nbsp;The baseline dataset consists 104 OCD patients and 82 healthy controls&nbsp;were anonymously enrolled from our Institutional database. Part of the data from this cohort has been published previously [1, 2]. In this baseline dataset, 27 refractory patients underwent ventral capsulotomy with complete postoperative MRI scanning and clinical assessment.&nbsp;Exclusion/inclusion criteria, surgical procedure, and detailed clinical information were described in previously published work [1].&nbsp;Clinical assessment included Y-BOCS, HAM-A, and HAM-D (17-item version).&nbsp;The fMRI data were minimally preprocessed using Statistical Parametric Mapping; the preprocessing pipeline details&nbsp;were described in&nbsp;previous studies [1, 2].</p> <p>1.
