AD and ischemic vascular dementia (IVD) subtypes were screened for 'mixed cortical and cortical dementia' using clinical case conference and imaging analysis of vascular disease severity. Junque = Junque visual rating scale (reference) for white-matter abnormality severity (0–40 scale; 40 = maximum white-matter abnormalities)
