Alzheimer’s disease affects as many as 4 million Americans. It can affect almost any age but still is more common in the ederly. As ageing population continues to increase, so does the disease. Today, 3% of the people ages 65 to 75 have alzheimer’s, 10% of those aged 75 to 85 have alzheimer’s and half the age 85 may have it to. Without a new cure it is estimated that alzheimers will affect over 14 million people by 2050.
(r.1) Statistics exemplify the discovery of one specific gene which contributes to the increasing rate of late-onset Alzheimer’s. Person’s with rare, familial types of Alzheimer’s are found connected to hundreds of families linked to a specific gene. (r.1) Those whom inherit the specific gene are almost guaranteed to obtain the Alzheimer’s disease. The gene also will affect the person by the age of sixty-five, and even as early as their thirties and forties. (r.1) Another popular theory for the cause of the disease other then genetics includes the decreasing of brains cells through either strokes or ageing.
Dementia is defined by the World Health Organization as a syndrome due to damage of the brain cells that most often chronic and progressive in nature. Some of the cortical functions that become impaired include memory, thinking, orientation, comprehension, calculation, learning capacity, language and judgment. Other manifestations that may accompany this disease are deterioration in emotional control, social behavior or motivation (Ouldred & Bryant, 2009) Dementia is not a normal part of aging, however it occurs most frequently in the older population. Fifteen percent of Americans over the age of sixty-five have dementia, and as the average life span continues to increase, so will the number of those affected by dementia (Fredman, James, Johnson, Scholz, & Weuve, 2012). The purpose of this paper is to discuss the pathophysiology, risk factors, symptoms, and treatment options for different types of dementia.
It is also known that people with Alzheimer’s have reduced levels of brain chemicals, such as acetylcholine (1). Additionally, people with Down’s Syndrome are more likely to acquire this dementia, with about fifteen percent of Alzheimer’s patients showing a family history of this disease. This leads many scientists to believe that there is a genetic link to the disease. When twins have been studied, a high agreement rate has been found for the disease. Furthermore, there is sometimes a very dominant pattern of inheritance of this disease, where a person has a fifty percent chance of acquiring it if either parent has Alzheimer’s (autosomal dominant transmission) (1,2).
One of such illness is dementia. As the life expectancies of the general population have dramatically increased since the turn of the century, more and more people are at risk of developing dementia (National Institute of Aging, 2000). Dementia is affecting an increasing number of people every year. According to Ferri et al. (2006), 4.6 million people throughout the world are diagnosed with dementia every year, and the number of people in Europe suffering from dementia will increase to 13 million in 2040; and Wimo et al.
Though this disease can still occur in elderly men, it is more likely to occur in elderly women. Alzheimer’s disease is a progressive neurologic disease of the brain. This formidable and terrifying disease leads to the irreversible loss of neurons along with the inevitable loss of intellectual abilities, including memory and reasoning (MNT-What is Alzheimer's disease?, 2009). Alzheimer’s disease becomes severe enough to impede social or occupational functioning. This article also stated that Alzheimer’s disease gets worse over time and continues to progress for the rest of an elderly person's life.

The symptoms depend on the part of the brain affected, but the most common signs include extreme changes in behavior and personality. For those with Frontotemporal dementia, 30 to 40 percent have a family history of dementia, suggesting the illness has a genetic component (Memory impairment. (2010).
Alzheimer’s disease is a rapid growing disease that is affecting millions of people around the world. From the discovery of Alzheimer’s disease in 1906 to now, technology has improved in finding the details in the brain and nerve cells. Research centers and doctors are working together to find the cure and other treatments to relieve the symptoms. It’s depressing to see these elders not being able to remember their own family and going through all the pain that this disease causes. Not only does it affect the patient but also the caregivers and/or family around them.
Estimates vary, but experts suggest that as many as 5.1 million Americans may have Alzheimer’s disease. Alzheimer’s disease is the most common cause of dementia among older people. Dementia is the loss of cognitive functioning—thinking, remembering, and reasoning—and behavioral abilities, to such an extent that it interferes with a person’s daily life and activities. Dementia ranges in severity from the mildest stage, when it is just beginning to affect a person’s functioning, to the most severe stage, when the person must de... ... middle of paper ... ...ng with the disease. With numbers this high, there are several important things that someone developing Alzheimer’s or the loved ones of someone with Alzheimer’s should be aware of.
Although Dementia is found in people 80 and over, it can be found in people 60-79 as well. Even in young adulthood, causes of Dementia are widely ranged but the two main causes of Dementia are vascular dementia and Alzheimer’s disease. The first symptoms of dementia are people forgetting basic semantic information. Simply, they cannot recall important facts such as their name or number or even how to get home (Experiencing the Lifespan name, p.439). In order to get diagnosed with dementia you must have serious memory impairments as well as difficulties managing life (Experiencing the Lifespan chapter 14, p.439).
