How Does Homeostasis Affect Early Adulthood

Changes in Tissue Homeostasis of the Elderly That Result in Altered Cognitive; Motor Abilities. As we age, homeostasis is harder to achieve within all of our cells. The cardiac muscle tissue and the walls of the blood vessels thicken, decreasing the amount of oxygen and nutrients that is pumped out to the entire body. The thickness of the blood vessels makes it hard for nutrients to enter the other tissues body, and for wastes to leave these tissues. Water is also harder to retain in the body as we get older, which decreases blood pressure and slows the speed of nutrients circulating within the body. This can effect motor abilities in an individual, by making their muscles weaker due to lack of nutrients and poor hydration (1). This aspect of cellular aging is concentrated on physical declination rather than cognitive declination. Becoming physically less able can be upsetting for the aging individual. Not being able to perform day to day tasks can change almost everything about a person's lifestyle. A good …show more content…
Just as with grey matter, the cells in the white matter atrophy, resulting in shrinkage. Homeostasis is affected by this atrophy of cells, and can cause lesions on the brain in the white matter. These lesions can effect cognitive abilities in similar ways as they do in the grey matter, for example, by inducing symptoms of dementia. There are many other diseases which involve lesions on the white matter of the brain, including Parkinson's Disease and Multiple Sclerosis. There are emerging therapeutic remedies for these disorders, which include gene therapy and stem cell therapy. Deep brain stimulation, or DBS, is also used to treat disorders effecting the white matter of the brain, in particular Parkinson's Disease, by blocking the electrical signals which target the affected areas of the brain and cause tremors and other symptoms of the disease
