This document discusses stroke and lupus. Lupus is an autoimmune disease that can affect multiple organs, including lungs, kidneys, heart, blood, and nervous system. Stroke occurs when blood flow to the brain is interrupted. Lupus can cause stroke through abnormal antibodies that attack blood vessels and cause blood clots, vasculitis which causes inflammation and reduced blood flow, and atherosclerosis where arteries are narrowed. Managing lupus through medication and lifestyle changes such as diet, exercise, and stress reduction can help reduce the risk of stroke. It is important for people with lupus to see their doctor regularly and seek immediate medical help if they experience signs of stroke.
