Being aware is the key to prevent any disease from developing. Because of the medical advancement we have today, the chance of getting infected with and developing diseases has decreased rapidly. However, just because the percentage has been lowered does not mean it is fine to forget about the existence of diseases. Are you aware of how many fatal diseases you can develop? The way you live and act can affect the possibility of you developing a disease, that you can prevent by being careful and consider about how you are living your life. However, the disease you possess in your genes passed down from past generations in your DNA cannot be changed. Another thing to be aware of is that genetic diseases are common to those who come from a general …show more content…

Tay-Sachs disease is passed down from generation to generation by a certain gene. It is associated with chromosome 15, known as the HEXA gene. You have 23 chromosomes in total, including the X and Y chromosomes. On chromosome 15, the DNA codes for an enzyme, which is a substance that allows you to speed up chemical reactions in your body, that breaks down unneeded substances from your body. This enzyme is called beta-hexosaminidase. This unneeded substance that this enzyme breaks down is a fatty substance called GM2 ganglioside. If the enzyme is able to break down this GM2 ganglioside in the lysosomes, an organelle in your body where the breaking down of this substance occurs, there is no problem. However, in the case of Tay-Sachs disease, there is a change in this enzyme which will destroy this process. The enzyme not functioning properly will result in swelling of your nervous system, which will later on lead to the death of nerve cells. The swelling will eventually reach the brain and spinal cord, resulting to damage them. By the brain getting damaged and not functioning well it affects the nervous system. Having dysfunction in their brain and spinal cord, the infant would not be able to survive for long. Even with help with force-feeding, respiratory care, and other ways in which the hospital does to keep the infant to be alive, it would not last for long. Due to the weakening of the infant’s immune system, they eventually get infected with other diseases which cause their

Tay-Sachs disease is a rare and fatal genetic disorder that destroys neurons in the brain and spinal cord. The disease appears in three forms, Juvenile Onset, Late Onset (known as LOTS), and the most common form, Infantile (also known as Classic). The differences between the three forms of the disease are related to the age at which the symptoms of the disease begin to form. Tay-Sachs results from a deficiency of the enzyme hexosaminidase A, which plays a vital role in removing a fatty substance, called GM2 gangliosides, from neurons.

Tay-Sachs disease is a neurodegenerative disorder that is known to be genetically inherited.

Non Shared Diseases Research Paper

The social and economic impact of non-shared diseases threatens progress towards sustainable development. Uncommon diseases are the leading cause of death, resulting in 16 million premature deaths each year. The four major groups of extraordinary diseases - cardiovascular disease, cancer, respiratory illness and chronic diabetic - account for 82% of all non-fatal deaths3. By 2025, the global economic costs of four of these groups are expected to exceed $ 51 trillion. Despite the common belief that unidentified diseases are a "disease of prosperity" affecting only the populations of rich countries, the unknown diseases do not affect people in low-income and middle-income countries. The possibility of premature deaths due to unusual diseases in a low- and middle-income country is four times higher than in high-income countries. For young people, it is important to understand non-shared diseases and their risks. Two-thirds of adult deaths are related to childhood5 or youth behavior: over 150 million young people smoke, 5 81% of young people do not get enough physical activity, 6 11.7% of teens have episodic heavy consumption and 41 million Focused behaviors and unhealthy living conditions are assured that ill-health continues to affect

The Decline of Infectious Diseases
1109 Words | 3 Pages
In the 1960s, doctors in the United States predicted that infectious diseases were in decline. US surgeon Dr. William H. Stewart told the nation that it had already seen most of the frontiers in the field of contagious disease. Epidemiology seemed destined to become a scientific backwater (Karlen 1995, 3). Although people thought that this particular field was gradually dying, it wasn’t. A lot more of it was destined to come. By the late 1980s, it became clear that people’s initial belief of infectious diseases declining needed to be qualified, as a host of new diseases emerged to infect human beings (Smallman & Brown, 2011).With the current trends, the epidemics and pandemics we have faced have created a very chaotic and unreliable future for mankind. As of today, it has really been difficult to prevent global epidemics and pandemics. Although the cases may be different from one state to another, the challenges we all face are all interconnected in this globalized world.
