Down Syndrome: The Cause Of Alzheimer's Disease

Decent Essays

‘’Down syndrome is a type of mental retardation caused by extra genetic material in chromosome 21’’ (8), Down syndrome can cause a number of medical complications (6). Some of these complications are more serious than others, but most of them can be treated (6). Although Down Syndrome patients do not live for a long time, but their short life span is challenged with many critical problems. The life expectancy of people with Down syndrome increased dramatically between 1960 and 2007 and in 1960, on average, persons with Down syndrome lived to be about 10 years old; however, in 2007, on average, persons with Down syndrome lived to be about 47 years old (7). Furthermore, Down syndrome affects the patients life mentally, socially, and physically. …show more content…

Early-onset Alzheimer’s disease is more common in adults with Down syndrome than in the general population (2). By the age of 40, almost 100% of patients who suffer from Down syndrome have the likelihood in the brain associated with Alzheimer’s disease (dementia) (1). Amyloid precursor protein (APP), which produces toxic amyloid protein (beta-amyloid (3)) and which forms plaques in the brain and likely harms the brain cells and their connections, is coded for chromosome 21 (1). Due to the fact that people with Down syndrome have an extra copy of chromosome 21, they produce 1.5 times as much APP as other people (1). In effect for this extra production, it seems to result in an excess tendency for the abnormal amyloid breakdown product to build up (1). This increasing of APP causes earlier appearance of the brain changes typical of Alzheimer’s disease. The risk increases with age, however, Alzheimer’s disease is not inevitable in people with Down syndrome (2). Moreover, some social problems occur due to hearing …show more content…

People with Down syndrome are typically hyper flexible and have large joints (hips, knees, etc.), therefore, they suffer from Osteoarthritis. Additionally, adults who are overweight or who were previously overweight are at an increased risk of having Osteoarthritis. Arthritis is aching and can lead to a decrease in movement and a decrease in desire to participate in activities. For some patients, the soreness leads to negative behavioral changes. Furthermore, untreated pain increases the risk of further immobility and deconditioning due to reluctance to participate in activities or
