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.Know More
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
Also referred to as peripheral artery disease, arterial disease in the legs is caused by a condition called arteriosclerosis, hardening of the arteries. This condition occurs when plaque accumulated on the walls of the arteries making them narrow. Consequently, the arteries become stiffer, inhibiting proper flow of blood, as stated by the National Institutes of Health MedlinePlus.Full Answer >
Chronic microvascular ischemic change is a term that describes areas in the brain where tiny blood vessels have ruptured or clotted off, causing limited blood flow, or ischemia. It is a common finding in adults over 50 with certain chronic health conditions, such as high blood pressure, atherosclerosis or diabetes.Full Answer >
Ischemic colitis occurs when there is a lack of blood flow to the colon, which causes cells in the digestive system to become deprived of oxygen, according to Mayo Clinic. This results in abdominal pain and colon damage.Full Answer >
A Transient Ischemic Attack, or TIA, occurs when blood flow to the brain is hindered or slowed and is similar to a mild stroke, according to WebMD. A TIA is often referred to as a mini stroke because the effects are typically short lived and mild; however, having one could mean that a patient is likely to have another, more serious stroke in the future, which can cause permanent damage.Full Answer >
