Module 2 SLP: Target Population

Descriptive Epidemiologic Analysis of Cerebrovascular diseases

Target Population

The target population which I selected for descriptive epidemiologic analysis is the elder population, especially those suffering from cerebrovascular disorders and the risk of CVD in elder people living near the airports (Kantor, 2000). Descriptive epidemiology is fundamentally concerned with the process of documenting the extent or magnitude of the disease or issue of injuries, and then explaining it with respect to the individual characteristics and behavior of those that are at high risk. Along with that the timing and place of occurrence are also the matter of concern (Rockett, 2005).

Descriptive Epidemiologic Analysis

Cardiovascular diseases (CVDs) are the group of heart diseases as well as blood vessels. It includes cerebrovascular diseases, hart attacks (coronary heart diseases), disease peripheral artery, congenital heart diseases, rheumatic heart disease and heart failure (Mostafaie et al., 2010). Here we are specially concern with the cerebrovascular disease in elder population, especially those who are living near airports, because it has been noticed by studying few studies that the noise from airport is also a risk factor for developing CVD. Cerebrovascular disorders means a collection of conditions that influence the blood circulation to the brain, causing restricted or minimum flow of blood to the brain areas that are affected. Cerebrovascular vascular disease can be caused by atherosclerosis. Throughout this process, levels of high cholesterol along with inflammation in arteries areas in brain make the cholesterol advance in the vessel as a waxy, thick plaque. This plaque can constrain, or totally obstruct, flow of blood to the brain, causing the condition of stroke, dementia or transient ischemic ambushes, which might lead an assortment of other complications of health.

In women having defective collagen, the arteries' weak branching points forms projections with an extremely thin endothelium covering that can tear to bleed without difficulty with insignificant increase in pressure of blood. This can additionally happen with capillaries that are defective brought about by cholesterol deposition by tissues particularly subjects having hypertension with or without dyslipidemia. Provided that bleeding happens in this process, the coming about impact is a hemorrhagic stroke as intra-cerebral hemorrhage, subarachnoid hemorrhage, or both. A blood pressure fall throughout the period of sleep or rest can cause marked reduction in the flow of blood in narrowed vessels of blood. This causes ischemic stroke in the morning.

On the other hand, a sudden increase in pressure of blood because ...
