Lacunar Stroke

Lacunar stroke, also known as lacunar infarct (LACI) is characterized by the blockage of small arteries which transport blood to the brain’s deeper structures. The lack of oxygen leads to brain cell death. “Lacunae” are the “empty spaces” in the brain due to the lack of blood supply. This is the most common kind of ischemic stroke; in fact, around 25% of ischemic strokes are lacunar infarcts. The symptoms include numbness, weakness or paralysis of the limbs, eyes, and/or face, difficulties in walking and speaking, clumsiness, and other neurological conditions. The risk factors include hypertension, diabetes mellitus, and smoking.
