Voxel-wise meta-analysis of structural changes in gray matter of Parkinsons disease patients with mild cognitive impairment

Braz. j. med. biol. res; 53 (6), 2020
Evidence from previous voxel-based morphometry (VBM) studies indicates that widespread brain regions are involved in Parkinson's disease with mild cognitive impairment (PD-MCI). However, the spatial localization reported for gray matter (GM) abnormalities is heterogeneous. The aim of the present study wa...

miR-22 and cerebral microbleeds in brainstem and deep area are associated with depression one month after ischemic stroke

Braz. j. med. biol. res; 53 (5), 2020
In this study, we aimed to explore the relationship among miR-22, deep cerebral microbleeds (CMBs), and post-stroke depression (PSD) 1 month after ischemic stroke. We consecutively recruited 257 patients with first-ever and recurrent acute cerebral infarction and performed PSD diagnosis in accordance wit...
