What is diffuse cerebrovascular disease?

Affects whole brain: Strictly speaking, diffuse cerebrovascular(cv) disease refers to an entity that affects all of the vessels throughout the brain.That is both the large and small vessels. Many times the diffuse cv disease is inferred by the clinical findings or MRI findings-ie. Signs of stroke/ischemia in multiple areas throughout the brain. Diffuse processes like diabetes or lupus are examples that can lead to this.
