Is Alzheimer's linked to type 2 diabetes or high blood pressure?

If you want to reduce your risk of developing Alzheimer's disease, there are countless suggestions on the Internet to tell you what to do: control your blood pressure and blood sugar, lose weight, exercise more, and avoid type 2 diabetes. Of course, doing these things is good for your overall health, but new research suggests they may do nothing to reduce the risk of Alzheimer's disease.about 50 million people currently suffer from dementia, a figure that is expected to triple over the next 30 years. The most common form of dementia is Alzheimer's disease. People with the disease have a build-up of two proteins in their brains( β-amyloid and tau proteins), but it is not clear whether these proteins are the cause or consequence of the disease. What we do know is that the proliferation of this tangled protein prevents brain cells from functioning properly, leading to typical symptoms of dementia: memory loss, confusion, difficulty performing daily tasks, behavioural changes, hallucinations.the past decade, the role of cardiovascular disease and diabetes in the development of dementia has been emphasized. For some time now, researchers have known that these diseases are linked to vascular dementia. Vascular dementia occurs due to damage to blood vessels, such as atherosclerosis, which increases the risk of dangerous bleeding or blood clots in the brain. Blood clots and bleeding prevent oxygen from entering certain parts of the brain, causing these brain cells to die.high blood pressure and diabetes increase the risk of atherosclerosis, which affects the delivery of oxygen to the brain. Some people believe that the consequences of these diseases increase brain changes in people with Alzheimer's disease, so high blood pressure and diabetes are thought to increase the risk of developing Alzheimer's disease.the link between these factors, it is important to remember how accurate the diagnosis of dementia is. With the tools we have today, a person will be diagnosed with dementia, for example, Alzheimer's or vascular dementia with a 60-90% accuracy. So 10-30% of people diagnosed with dementia get the wrong diagnosis.the only accurate diagnosismost studies of the relationship between hypertension, diabetes and Alzheimer's disease are conducted in clinics. This means that the people in these studies are alive and may have been misdiagnosed. The only way to diagnose dementia is through an autopsy, to analyze brain samples under a microscope, so the best way to study this problem is through an autopsy, on the basis of which you can confirm that the subject's diagnosis is correct. This is the method used by the researchers in the latest study.researchers wanted to study whether there was a difference in the incidence of high blood pressure and diabetes between people with Alzheimer's and vascular dementia. Their study was based on 268 deaths, aged 65 and over. They analyzed brain samples to determine the diagnosis of Alzheimer's disease or vascular dementia. Using medical records and the Swedish National Diabetes Register, the researchers were able to determine whether their subjects had high blood pressure or diabetes, or both.found high rates of hypertension and type 2 diabetes in people with vascular dementia. People with Alzheimer's have significantly lower rates of both diseases.37 percent of people with Alzheimer's have high blood pressure. The proportion of vascular dementia group was 74%. 12 percent of people with Alzheimer's have diabetes, up from 31 percent of those with vascular dementia. In Sweden, 16 per cent of people over the age of 65 have diabetes. Some might speculate that people with Alzheimer's have a lower risk of developing diabetes, or that people with diabetes have a lower risk of developing Alzheimer's disease.despite these results, it is important to maintain blood pressure control and avoid type 2 diabetes. These are all factors that cause cardiovascular disease, which is the leading cause of death in the world. Instead, we hope our findings will increase knowledge of these risk factors and types of dementia. The correct correlation between risk factors and disease types will help scientists avoid misleading conclusions and meaningless treatment attempts. (Bio Valley bioon .com)
