Multivariate Classification of Major Depressive Disorder Using the Effective Connectivity and Functional Connectivity
Major depressive disorder (MDD) is a mental disorder characterized by at least 2 weeks of low mood, which is present across most situations. Diagnosis of MDD using rest-state functional magnetic resonance imaging (fMRI) data faces many challenges due to the high dimensionality, small samples, noisy and individual variability. To our best knowledge, no studies aim at classification with effectiv...
متن کاملCingulate cortex functional connectivity increase predicts relapse of major depression
Introduction: Recent functional imaging studies suggest alterations in cortico-limbic circuit connectivity in depression. Moreover, these functional connectivity (fc) changes were found to correlate with symptom severity and normalised upon antidepressant treatment (1). The direction of these fc changes is however debated with one group showing increased default network connectivity and another...
متن کاملMultisite functional connectivity MRI classification of autism: ABIDE results
BACKGROUND Systematic differences in functional connectivity MRI metrics have been consistently observed in autism, with predominantly decreased cortico-cortical connectivity. Previous attempts at single subject classification in high-functioning autism using whole brain point-to-point functional connectivity have yielded about 80% accurate classification of autism vs. control subjects across a...
متن کاملUnsupervised MRI segmentation with spatial connectivity
Magnetic Resonance Imaging (MRI) offers a wealth of information for medical examination. Fast, accurate and reproducible segmentation of MRI is desirable in many applications. We have developed a new unsupervised MRI segmentation method based on k-means and fuzzy c-means (FCM) algorithms, which uses spatial constraints. Spatial constraints are included by the use of a Markov Random Field model....
متن کاملMultivariate pattern classification of pediatric Tourette syndrome using functional connectivity MRI
Tourette syndrome (TS) is a developmental neuropsychiatric disorder characterized by motor and vocal tics. Individuals with TS would benefit greatly from advances in prediction of symptom timecourse and treatment effectiveness. As a first step, we applied a multivariate method - support vector machine (SVM) classification - to test whether patterns in brain network activity, measured with resti...
