LACUNAR INFARCTION Meaning and
Definition
-
Lacunar infarction, also known as a lacunar stroke, is a specific type of ischemic stroke characterized by the formation of a small localized area of tissue damage within the brain. This condition occurs when there is a blockage or occlusion of the small arteries that supply blood to the deep structures of the brain, such as the basal ganglia, thalamus, or white matter.
Lacunar infarctions are typically caused by the buildup of fatty deposits (atherosclerosis) or blood clots (thrombosis) within these small arteries, leading to the disruption of blood flow and subsequent damage to the surrounding brain tissue. The size of the affected area is usually less than 15mm in diameter, distinguishing it from larger infarctions.
Symptoms of lacunar infarction can vary depending on the location and extent of the brain damage, but commonly include sudden weakness or numbness in the face, arm, or leg, difficulties with coordination or balance, issues with speech or understanding, and changes in sensation or vision.
Diagnosis of lacunar infarction involves neurological examinations, imaging techniques such as magnetic resonance imaging (MRI) or computed tomography (CT) scan, and blood tests to rule out other potential causes. Treatment typically involves the management and prevention of risk factors, such as hypertension, diabetes, and hyperlipidemia, through lifestyle modifications and medication. Additionally, anticoagulants or antiplatelet drugs may be prescribed to prevent further clot formation and reduce the risk of recurrent strokes.
Prognosis for lacunar infarction can vary based on the severity of the stroke and the promptness of treatment. Generally, with appropriate medical intervention and rehabilitation, many individuals with lacunar infarctions can experience partial or full recovery and

Etymology of LACUNAR INFARCTION
The word "lacunar" originates from Latin and means "small cavity" or "hollow", and "infarction" is derived from the Latin word "infarcire", meaning "to stuff" or "to block".
In the context of medicine, "lacunar infarction" refers to a type of stroke caused by a blockage in the small penetrating arteries that supply blood to the brain's deep structures. The term "lacunar" is used because these blockages result in the formation of small cavities or holes within the brain tissue.
Overall, the word "lacunar infarction" combines the Latin roots to describe a specific type of stroke characterized by small areas of tissue damage caused by blocked blood vessels.
