Cognitive impairment (CI) is a frequent and disabling manifestation of multiple sclerosis (MS), yet its molecular underpinnings remain poorly understood. This study aimed to identify microRNA (miRNA) signatures and related gene expression changes associated with CI in MS. Forty-six people with MS underwent clinical, radiological, and cognitive assessment. Peripheral blood mononuclear cells were collected for miRNA profiling us...

Drawing is a multi-component process requiring a wide range of cognitive abilities. Several studies on patients with focal brain lesions and functional neuroimaging studies on healthy individuals demonstrated that drawing is associated with a wide brain network. However, the neural structures specifically related to drawing remain to be better comprehended. We conducted a systematic review complemented by a meta-analytic appro...
