These changes leave the body in a more vulnerable state and then leave the aging person at an even higher risk for other diseases. This shows that although aging has effects on DNA, DNA also has huge effects on aging and the rate at which people age. Aging also has the effect of changing some of the gene expressions in DNA. The genome for any living thing is always unstable to an extent. This is how it will always be because it is so intricate and there are so many different sequences that one little change can make everything go wrong.
A mutation in the Lamina A protein cell results in rapid aging, ultimately affecting how one lives their life. With an early diagnosis of Progeria, damage can be prevented and also following management precautions can greatly increase the quality of life. Works Cited Chien, H. (2012).

Its effects can be seen on our face and body as we grow from a child to an adult. Soon after our bodies have matured into young adults, the degenerative properties of aging begin to negatively impact the body. Aging goes deep beneath the superficial changes like of a balding head, wrinkled skin, or a grey head of hair. These inconspicuous changes occur inside the body affecting cells and organs such as the brain, heart, or lungs. In addition to the deterioration of health of the brain and heart; bones can become weaker and shorter and our vision and hearing impaired or even lost.

With the inherent instability of genes coupled with the mutations and the need for more stem cells to replace damaged cells due to carcinogens, it seems almost inevitable that with enough time every living organism would at some point acquire cancer. In conclusion, organisms have evolved to preserve a number of somatic cells for the purpose of maintaining their own genetic information. These stem cells not only play a key role in repairing and replacing damaged cells, but also serve a major purpose in passing genetic material through a germ line. Ultimately, “the slow and relentless accumulation of DNA damage and mutations eventually erodes away the genetic information that maintains homeostasis of the somatic cell population”, leading to the malfunctioning of cells and the evolution then of these dysfunctional cells (Kennedy, 2011).
People with dementia show deficiencies in neurocognitive function such as reduced memory and defective performance of mundane activities such as cleaning the house (Gallo et al., 2008). The ongoing changes and damaged brain cells are triggered by a build-up of irregular proteins in the genus. This means that the person’s symptoms worsen over time due to the continual feast of these proteins throughout the brain. Increased risk of dementia is associated with heart disease, diabetes and drug and alcohol misuse. Dementia is responsible for a large onus on the health care system and its occur... ... middle of paper ... ...entia UK: The full report.
In contrast, if the promoter is not functioning correctly, it could cause cell division too often thus causing the same effects as cancer. There are many steps to fixing a gene, scientists cannot move on to step two until they have successfully completed step one. Among these technical holdups, research in biotechnology has run into serious problems. In his article titled “Human Gene Therapy: Harsh Lessons, High Hopes”, Larry Thompson, tells of more setbacks the industry has come upon.
Aging occurs at the biological, psychological and social levels. With numerous theories of aging spanning over many disciplines, no one is truly certain why we age or how we cope with it. Fortunately, our knowledge of how the body regulates or governs the rate of aging is slowly being demystifyied and we now know more about this process. Activity and disengagement are two major psychosocial theories which describe how people develop in old age. Also known as the implicit theory of aging, the activity theory states that staying active and maintaining social interactions results in successful aging.
This can be beneficial to many who have fearful perceptions of aging due to the myths surrounding the aging process.

The best theories of aging include a biopsychosocial model, where all aspects of genes, biological, psycholigical and social influences are taken into account. Although there is great variability between individual differences of performance, the changes that occur during development and aging transpire within three categories: physical, cognitive, and psychosocial (cite). These changes are interconnected such that changes in one category will most likely affect other areas of a person’s life.
Because the term culture is broad and vague, it becomes arduous to agree on a single definite and specific meaning. However, culture is essentially integrated into our daily lives, and it is categorized into two major groups, the East and the West, which each has its similarities and differences. The most common amongst both culture is the theme regarding successful aging. Aging happens in every culture and every society, and successful aging concerns many researchers as they try to discover an answer to that may be able to apply to all cultures. Through the analysis of various research of numerous factors, it modifies the typical stereotypical thinking about cultural attitudes toward aging and strengthens the perspectives and understanding of Eastern and Western cultural differences.
Mutation: Werner Syndrome For most, aging is an enviable part of the life cycle, which often involves a progressive change in physical, cognitive, and psychological aspects. However, individuals diagnosed with Werner syndrome face an escalated biological clock so to speak. According to Pierce (2013), Werner Syndrome, is an autosomal recessive disease associated with premature aging and early death. The rare hereditary disorder was discovered by the German Scientist Otto Werner and affects approximately 1:200,000 births (Kuan, 2016). The following will review Werner syndrome, including accompanied symptoms, specific mutation, discovery or the disease, impact of the mutation, and the potential for genetic technology.
