What does small vessel ischemic changes mean?

Small vessel ischemic changes refer to alterations in the brain's white matter due to reduced blood flow in the small penetrating arteries and arterioles. These changes are often associated with chronic conditions like hypertension and Diabetes, leading to the degeneration of small blood vessels. Clinically, they can manifest as cognitive decline, gait disturbances, and other neurological symptoms. Imaging studies, such as MRI, can reveal these changes as hyperintense areas in the white matter.
