Chronic mouse brain hypoperfusion produces white matter damage; a feature of vascular cognitive impairment. Despite growing interest in this model, we have struggled to observe a strong phenotype. The present study aimed to improve the phenotype through extended hypoperfusion (6m). We examined the effect on various MR biomarkers including functional connectivity and vascular remodeling. We found massive structural changes including arterial neovessels, small subcortical strokes, and microbleeds. Animals showed behavioral deficits accompanied by changes in resting state MRI signals of the cingulate cortex, which is functionally connected to regions related to behavior (hippocampus) and emotion (amygdala).
