Lacunar stroke
(Redirected from Lacunar infarcts)
Lacunar stroke is a type of ischemic stroke that occurs when the flow of blood to one of the small arteries deep within the brain becomes blocked. These are often caused by the buildup of plaque, a condition known as atherosclerosis.
Causes[edit | edit source]
The primary cause of a lacunar stroke is ischemia, specifically in the deeper structures of the brain. This is often due to atherosclerosis, the buildup of plaque in the arteries. Other risk factors include hypertension, diabetes, smoking, and age.
Symptoms[edit | edit source]
Symptoms of a lacunar stroke can vary depending on the area of the brain that is affected. Common symptoms include weakness or numbness on one side of the body, difficulty speaking or understanding speech, and loss of balance or coordination.
Diagnosis[edit | edit source]
Diagnosis of a lacunar stroke involves a physical examination, a review of the patient's medical history, and imaging tests such as a CT scan or MRI. A lumbar puncture may also be performed to rule out other conditions.
Treatment[edit | edit source]
Treatment for a lacunar stroke typically involves medication to prevent further blood clots, control blood pressure, and reduce cholesterol levels. In some cases, surgery may be required to remove the blockage.
Prognosis[edit | edit source]
The prognosis for a lacunar stroke is generally good, with many patients experiencing a full recovery. However, some may have lasting effects such as weakness or difficulty speaking.
Prevention[edit | edit source]
Prevention of lacunar strokes involves managing risk factors such as hypertension, diabetes, and high cholesterol. This can be achieved through a healthy diet, regular exercise, and medication if necessary.
