Microglia modulate the cerebrovascular reactivity through ectonucleotidase CD39

Nature Communications
Microglia and the border-associated macrophages contribute to the modulation of cerebral blood flow, but the mechanisms have remained uncertain.

Cerebral Blood Flow in Mild Cognitive Impairment and Dementia: A Systematic Review and Meta- Analysis of Transcranial Doppler Studies

Cerebral Circulation - Cognition and Behavior
Introduction: Reduced cerebral blood flow has been associated with cognitive decline and incident dementia, with oxidative stress and reduced beta-amyloid clearance as possible mechanisms for neurodegeneration.

Cerebral Vasoreactivity During Acute and Recovery Phase Post-Concussion: A Pilot Study [PDF]

, 2016
The diagnosis of sports-related concussion is based mostly on clinical symptoms. Return-to-play decisions are made when the athletes are symptom free; however, some metabolic and physiological impairments may persist such as impairments in cerebral blood

Perfusion-weighted magnetic resonance imaging of the brain: techniques and application in children [PDF]

, 2018
Perfusion-weighted magnetic resonance imaging (PWI) has been proposed as an attractive non-invasive tool for evaluating cerebral haemodynamics. Quantitative maps of cerebral blood flow (CBF), cerebral blood volume (CBV), mean transit time (MTT), time to ...
