Pathophysiology And Etiology

Definitions Stroke A stroke (apoplexy) is the sudden onset of weakness, numbness, paralysis, slurred speech, aphasia, problems with vision and other manifestations of a sudden interruption of blood flow to a particular area of the brain. The ischemic area involved determines the type of focal deficit that is seen in the patient. Transient Ischemic Attack (TIA) A TIA is similar to a stroke, but the interruption of blood flow is temporary. The clot resolves sporadically. The symptoms are relatively the same as a stroke but last less than 24 hours, whereas stroke symptoms persist for greater than 24 hours. Causes of Stroke The primary pathophysiology of stoke is an underlying heart or blood vessel disease. The secondary manifestations in the brain are the result of one or more of these underlying diseases or risk factors. The primary pathologies include hypertension, atherosclerosis leading to coronary artery disease, dyslipidemia, heart disease, and hyperlipidemia. The two types of stroke that result from these disease states are ischemic and hemorrhagic strokes. Non-reducable Risk Factors The possibilities of a stroke occurring increases with age. For every decade (10 years) over th Continue reading >>

    My urine is real dark and wondering if my kidneys are messed up? I'm taking 50 units of Lantas a day and between 18-more units of Novlog three times a day. Wondering if I need to drink more water?

    Diabetes can increase your risk for many health conditions, including stroke. In general, people with diabetes are 1.5 times more likely to have a stroke than people without diabetes. People with diabetes are often left with too much sugar in their blood. That’s because their body is often unable to maintain the delicate balance that insulin plays in helping blood cells create energy from sugar. Over time, this excess sugar can lead to the buil ...

  • How Are Diabetes And Stroke Related

    If you have diabetes, your risk of having a stroke is greater than that of someone without diabetes, even if you are otherwise healthy. Here's why: Diabetes can damage your blood vessels, so they are more prone to blockage. Your brain needs oxygen to survive. When you have a stroke, one or more of the blood vessels that delivers oxygen to the brain has become blocked. Also, with diabetes, the blood is thicker and more prone to clotting, thus slow ...

    Diabetes symptoms can quickly turn into emergencies. The disease of diabetes was the seventh leading cause of death in the United States in 2010, claiming nearly 70,000 lives. Responding promptly to symptoms of a diabetic emergency can be lifesaving. Causes and types Both type 1 and type 2 diabetes inhibit the body's ability to manage blood sugar levels. Type 1 diabetes does so by destroying the cells that produce insulin. Type 2 diabetes reduces ...

    Epidemiology and possible mechanisms Stroke affects more than 700,000 individuals each year; it is the third largest cause of death and the largest cause of adult disability in the U.S. Diabetes is a major risk factor for the development of stroke, yet this risk is not realized or understood by patients with diabetes. This likely reflects a lack of understanding within the medical community of how diabetes confers this risk. We will explore the p ...
