Lacunar infarct, also called lacunar stroke, occurs when small arteries in the inner brain get blocked due to inadequate blood flow. These arteries are little and branched, making them highly vulnerable to blockages. Lacunar infarct is a type of ischemic stroke characterized by blockages in the blood vessels within the brain.

The following are the main causes of lacunar infarct:
Lacunar infarcts rarely show any specific symptoms. The symptoms depend upon the affected brain region. A lacunar stroke usually occurs suddenly without warning signs. Symptoms include:
Treatment for lacunar infarct is the same as ischemic strokes. Following are the treatment options for Lacunar infarct:
Thrombolysis: This involves using medications and mechanical medical devices to open the blockages of the arteries. It is usually performed as an initial treatment for less dangerous strokes, especially when symptoms last for less than 4.5 hours.
Thrombectomy: A surgical procedure performed to remove blood clots when symptoms last for more than 4.5 hours and less than 24 hours.
Medications after surgery: After performing the above-mentioned procedures, your doctor will prescribe you a blood-thinner for at least 3 months to prevent further blood clotting. You may also be put on medications for blood pressure, blood sugar, or any other prior health complications.
Post-surgery Therapies: Different types of therapies are given for several months after stroke for quick healing. The purpose of these therapies is to get you back in motion by improving your motor skills. Therapies include:
Following are the reasons that can be a cause of Lacunar infarct:
Lacunar infarct is usually diagnosed accidentally when other conditions are being looked for in imaging techniques. If you are showing signs of lacunar infarct, then your doctor first asks you for a CT Scan. A CT scan is done to rule out all the similar potential conditions.
Lacunar stroke can be life-threatening. Although we cannot rule out factors beyond our control like ageing and heredity, a good lifestyle can reduce the chances of a lacunar stroke to a very extent. Some of the most effective yet common preventive measures are as follows:
Secondary prevention includes therapies that are given after the first visible symptoms of lacunar stroke. It includes:
Antiplatelet monotherapy: it includes administering medicines aspirin, dipyridamole, clopidogrel, and cilostazol.
Statins and anticoagulants are also used. Epidemiology
The recovery rate of Lacunar infarct is higher than the other strokes affecting larger blood vessels. Although it's more common in older people, even after recovery, it left some sort of disability in the patient, especially those having cardiovascular disease or depression. Dementia is one of the most common after-effects. But, timely treatment can result in 100% recovery.
If a Lacunar stroke is left undetected or untreated even after developing signs and symptoms, it may lead to :
Lacunar strokes tend to generally happen in old age. Lacunar strokes are more likely to cause dementia in older patients. Multiple lacunar infarcts simultaneously cause physical and cognitive disabilities.
