What are small areas of lacunar infarct?

Small areas of lacunar infarct are tiny, localized strokes that occur in the deep structures of the brain, often due to the occlusion of small penetrating arteries. They are typically associated with chronic conditions like hypertension and Diabetes, which damage blood vessels over time. These infarcts can lead to various neurological deficits, depending on their location, and are often found incidentally on brain imaging. Despite their small size, they can contribute to cumulative cognitive decline and other functional impairments.
