One chronic disease that can cause decreased blood supply to the brain is cerebrovascular disease. This encompasses various conditions that affect blood flow to the brain, including ischemic stroke and transient ischemic attacks (TIAs). Other conditions such as atherosclerosis, where arteries become narrowed due to plaque buildup, can also contribute to reduced blood supply to the brain over time.
Additionally, conditions like diabetes and hypertension can lead to changes in blood vessels, increasing the risk of reduced cerebral blood flow. Chronic heart diseases, particularly those affecting the heart's ability to pump blood efficiently, can also have downstream effects on brain perfusion.
Maintaining cardiovascular health is crucial in preventing decreased blood supply to the brain and associated complications.
