Cerebral Microbleeds With Atrial Fibrillation After Ablation Therapy.
Front Cell Neurosci
February 2022
Background: The prevalence of cerebral microbleeds (CMBs) is significantly higher in patients with atrial fibrillation (AF) than in those without AF. CMBs in patients with AF have been reported to be primarily of the lobar type, but the exact cause of this remains unknown. We investigated the possibility that hemorrhagic transformation of embolic microinfarction can account for lobar CMBs.

- * A study with 101 patients showed high rates of microinfarctions detected by MRI immediately after the procedure, but many of these lesions disappeared by the 6-month follow-up.
- * Despite some increases in microbleeds, overall cognitive function, as measured by tests like the Mini-Mental State Examination, improved six months after ablation, along with other heart health indicators.
Background/aims: The missing fundamental phenomenon (MFP) is a universal pitch perception illusion that occurs in animals and humans. In this study, we aimed to determine whether the MFP is impaired in patients with Alzheimer's disease (AD) using an auditory pitch perception experiment. We further examined anatomical correlates of the MFP in patients with AD by measuring gray matter volume (GMV) on magnetic resonance images via voxel-based morphometric analysis.
