Factors of Ageing

Dementia & Elderly Care

Explaining factors which influencing ageing.

Genes


There are several genetic factors are implicated in aging. The specific gene combination (genotypes) determine lifespan, which as remarkable changes in duration are observed as a result of alteration in a single gene, as in human progeriod syndrome. In addition, mutations in genomic and mitochondrial BNA are consequences of reduces repair efficiency, and lead in part to deterioration of somatic stem cell function. Example of the important of genetic factors in againg include genes that maintain organism.
Eexapmple of the important if genetic factors in againg include genes that maintain organism structure and fuction through out life, alleles that enchance reproductive capacity early in life buut have negative ffects later in life when their impact has escaped natural selective pressue and constitutional mutations that are phenotypically relevant until late in life, when they have eluded selection and connot be removed from the population.
Some diseases are caused by a genetic mutation, or a permanent change in one or more specific genes. If a person inherits from a parent a genetic mutation that causes a certain disease, then he or she may inherit the diseases this could lower the change of then living lober. Such as sickle cell anemia, cystic fibrosis and early-onset familial Alzheimer’s dieses are examples of inherited genetic disorder. In other diseases, a genetic variant occur. This change in a gene can sometimes cause diseases directly. More often it act to increase or decrees a person risk of developing a disease or condition. When a genetic variant increase disease risk but does not directly cause a dieses, this is called a genetic risk factor


Nutrition


The following changes in the bodies f the ages may affect their nutrition, such the the intake of suffficiant quantaties of the correct kinds of food will meet all the nutritional needs of the elderly. Good nutrition also boost resistance to diseases and stress. It also allows the inherited constirion to come into it own, so there for the elderly person who is genectaiclly programmed to remain young, for a long period, is enavbled to reach a high age.

Although heredity does play a part a paty on the incediance of diesases resulating of healrt attacks, strokes, hypertension, diabetes mellitus, gal bladder, liver, kidney, and skin diesases, as well as many other aliment, are decidly influced by nutrition.

The body changes with age, a large percentage pf elderly people do not have all theirown teeth. Some are toothless and other stuggle with ill fitting dentures. Food ids there for insufficiently chewed or kinds that require a little chewing afre given prefernace. The good that are firmer and contain a lot of good fiber.eg fruit and vegatble. This could be replayed by soaked bread and rusks, usally white and other soft food. Such food has sma;; volume, consequalty there is a decrease in the movemen of he bowel and gut. This results in the slower passage of food along the gigestive tract and gives rise to such problems as indigestion and constipation


Life Style

Many studies have examined that the individual effects of smoking, physical inactivity, poor diet and drinking alcohol have been established that they are independelty associalted with poorer health, this could speed up their aging process and because people often engage in multiple poor lifestyle choices that could shorten their life span. So many studies have shown hat smoking was more stromgly associated with death from cardiovascular dieases. The center for diseases control (CDC) also stafes that health lifsty are more influctial then genetics to avoid the deteriolation that is associalted with aging. The CDC has recommended that people who are phsycally active, eat healthy diet, do not use tabacco and practise other healthy begavhiors that reduces the risk of chronic dieseases. Againg is ineveitable, but the emphasize that bbeing puscally fit is the key to healthy againg

the elderly should challenge their mind, they should learn new skill and rehular mental activity that promote health mental functioning.

Environment

Medical research has revealed that environment factors play a major role in the majority of cases of Alzheimer’s and Parkinson disease. The diet, exercise, exposure to toxic chemicals and other environment pollutants and socioeconomic street can altar biochemical pathways influencing the risk of these disease increasing the risk of aging and other chronic diseases such as, diabetes, obesity, cardiovascular diseases and metabolic syndrome. Their phycial apperances is also effected bu the environment. The skin is the largerst organ in the body but eventually it starts to age as we growm, skin aging is also affected by the exposure to different environmental factors, well known environmemtal factors leading to extrinctic skin againg are sub exposure and smoking. Aip pollution represents another environmental threat to which million of human worldwhide are exposed to. Adverse effect of air pollution on human health are currently a serious concern which speed up the ageing proses, but has been shown to include a higher risk for cancer, pulmonary and cardiovascular disease.



Social isolation


It has been statiscally proven that older adults who feel most isolated report 65 percent more depressive sypmtoms then those who feel least isolated, regardless of their actual level of connectdness. The consequances of poor mental health can be substantial, as deteriorating mental health also reduces people willingness to be physically fit, by doing excerside and may increase health risk- behaviroiys such as cigarette snoking and alcohol use. The experts have found out that the most socially connected elderly are three times as likelty to be have very good or excellent health compared to those who are least connected, regardless of whether they feel isolated. Whereas the adults who feel least isolated are five times as likely be reported excellent heath as those who feel much more isolated, regardless of their level of social connectedness. It is ineveitable the aging often bring changes in social relationship as indivdiel retire, take up new activities, endure losses and experience health changes. It has been kown that a strinking circle of family and friends can lead to feeling of lonilesness or isolation.
