Small vessel ischemic disease is also referred to as lacunar infarction; it is diagnosed when there is a blood flow blockage in smaller arterial blood vessels. It is linked to hypertension and stroke. Studies have also shown a significant link between small vessel ischemic disease and Alzheimer's disease.Continue Reading
Small vessel ischemic disease is caused by a variety of factors. Risk factors include high blood pressure, high cholesterol and diabetes. The exact mechanism by which small vessel ischemic disease occurs is currently not known, but one of the most common markers of the disease is white matter lesions of the subcortical area of the brain.
As small vessel ischemic disease progresses, the blood vessel walls become thickened. Thickening of the vessel walls is referred to as atherosclerosis; over time the thickened walls also become hardened. As the vessels thicken and harden, it becomes more difficult for oxygen and important nutrients to reach the brain. The blood supply to specific areas of the brain is also hindered, leading to ischemic brain tissue. Damaged brain tissue and lack of oxygen to certain areas of the brain put the individual at a high risk for stroke and dementia. Physical symptoms of the disease's progression include slow and slurred speech, an inability to solve rational problems, poor judgment and a lack of emotion.Learn more about Conditions & Diseases
A small vessel disease such as leukoaraiosis leads to the blockage of blood to the brain, depriving the brain cells of the needed nutrients and oxygen, according to Life Extension. The effect of the blockage is dementia, which significantly reduces the thinking capacity of the person.Full Answer >
The detection of a bruit, or swishing sound, when auscultating the left carotid artery suggests turbulence in blood flow through the vessel, which indicates stenosis or atherosclerosis, reports MedicineNet. The accumulation of plaque in the carotid arteries is a cyclic process, which causes increased pressure that causes further plaque buildup.Full Answer >
Symptoms of a spinal cord stroke, or infarction, include severe back pain and pain through both legs, according to the National Institute of Neurological Disorders and Stroke. Those limbs become weak or even paralyzed, and leg reflexes diminish. The stroke victim feels neither pain nor temperature and sometimes becomes incontinent.Full Answer >
