Thalamocortical Dysconnectivity in Treatment-Resistant Depression
Thalamocortical connectivity is associated with cognitive and affective processing. The role of thalamocortical connectivity in the pathomechanism of treatment-resistant depression (TRD) remains unclear. This study included 48 patients with TRD and 48 healthy individuals. We investigated thalamocortical connectivity by performing resting-state functional MRI with the bilateral thalamus as the seed. In addition, patients with TRD were evaluated using the Montgomery–Åsberg Depression Rating Scale (MADRS). Compared with the healthy individuals, the patients with TRD exhibited increased functional connectivity (FC) of the thalamus with the insula and superior temporal cortex and reduced the FC of the thalamus with the anterior paracingulate cortex and cerebellum crus II. Our study may support the crucial role of thalamocortical dysconnectivity in the TRD pathomechanism. However, the small sample size may limit the statistical power. A future study with a large sample size of patients with TRD would be required to validate our findings.
期刊介绍：
The Journal of Neuroscience Research (JNR) publishes novel research results that will advance our understanding of the development, function and pathophysiology of the nervous system, using molecular, cellular, systems, and translational approaches. JNR covers both basic research and clinical aspects of neurology, neuropathology, psychiatry or psychology.
The journal focuses on uncovering the intricacies of brain structure and function. Research published in JNR covers all species from invertebrates to humans, and the reports inform the readers about the function and organization of the nervous system, with emphasis on how disease modifies the function and organization.
