One chronic disease that can lead to decreased blood supply to the brain is atherosclerosis. Atherosclerosis is characterized by the buildup of plaques in the arteries, which can restrict blood flow, including to the cerebral arteries that supply the brain.
Additionally, conditions such as chronic hypertension (high blood pressure) can also contribute to reduced blood flow to the brain over time by damaging blood vessels and increasing the risk of stroke. Another related condition is cerebral ischemia, which refers specifically to a reduction of blood flow to the brain that can lead to various neurological deficits.
Other chronic diseases like diabetes and heart disease can further contribute to vascular problems that may lower blood supply to the brain. Regular monitoring and management of these conditions are essential to minimize the risk of complications related to reduced blood flow to the brain.
