What condition involves diseases of the brain's vasculature that can lead to strokes and lesions?

Cerebrovascular disease encompasses a range of disorders that affect the blood vessels of the brain, which can result in strokes and lesions. This condition is primarily related to issues such as reduced blood flow, blockages, or bleeding within the brain's vascular system. Strokes, which can be ischemic or hemorrhagic, are a direct consequence of cerebrovascular disease.

While other conditions like vascular dementia are indeed associated with impaired blood flow and may lead to cognitive decline, cerebrovascular disease is broader and includes all pathology affecting the brain’s circulation. Alzheimer's disease and frontotemporal dementia are primarily neurodegenerative disorders associated with specific types of brain cell damage rather than direct vascular issues. Thus, cerebrovascular disease is the most accurate term to describe conditions related to diseases of the brain’s vasculature leading to strokes and lesions.
