In times past many people thought that memory loss was a normal occurrence for elderly people. This thinking was major reason for why Alzheimer’s disease was not caught until very later in the stages. Alzheimer’s disease is not a normal part of aging. After heart disease, cancer, and strokes, Alzheimer’s is the most common cause of death in adults in the Western world. “It is estimated that 4.5 million Americans over the age of 65 are affected with this condition. After the age of 65, the incidence of the disease doubles every five years and, by age 85, it will affect nearly half of the population” (Robinson).

The disease called Alzheimer’s is the fourth leading cause of death in the United States (Weiner, 1987). It is estimated that the elderly population will double between now and 2030. During this period, the number of elderly will grow by an average of 2.8% annually (U.S. Census Bureau, 2001). By 2050, the number of people with Alzheimer’s is estimated to range from 11.3 million to 16 million (Alzheimer’s Association, 2005). These startling numbers should prompt an examination into one of the leading causes of death among this group of people. Understanding what Alzheimer’s is and the known causes of the disease are a good starting point. For those who have aging family members, knowing the risk factors and warning

Memory span is a measure of short term memory and its capacity through the use of a list. Participants are asked to review a list of items, retain, and immediately recall as accurate as possible. The list may be conducted with a random list of numbers, words, or letters since these items may influence differently amongst each participant. The list is also varied in item length to test in which particular length the participant is subject to make the least of errors and determine their memory span. The average short-term memory capacity is ranged

An estimated 47.5 million people suffer from dementia. Every 4 seconds one new case of dementia is diagnosed. Dementia is a term that describes certain symptoms such as impairment to memory, communication and thinking. It is a group of symptoms and not just one illness. Even though one‘s chance of getting dementia increase with age, it is not a part of aging. Dementia is usually diagnosed after a series of assessments that includes a physical evaluation, memory tests, imaging studies and blood work. It affects three aspects of one’s mental function, cognitive dysfunction (Problems with memory, language, thinking and problem solving), psychiatric behavior (changes in personality, emotional control, social behavior and delusions) and difficulties with daily living activities (driving, shopping, eating and dressing). “The median survival time in women is 4.6 years and in men 4.1 years” (Warren, 2016).

The hypothesis that in Experiment 1, words at the beginning and end of a list would be better remembered while in Experiment 2, words at the beginning would be better remembered, was partially rejected, while still being partially true. The hypothesis that a delay would in fact make a difference was supported. In both tests, words in the first third seemed to be remembered by significantly more of the participants. However despite the predictions, words in the last third of experiment 1 seemed to be not significantly more than words in the middle third. experiment2 did seem to fit with the hypothesis, as the words at the start seemed to be higher than the rest, but there was a absurdity on word 16, “ocean,” which was recalled 7 out of the 9 times. Apart from this, experiment 2 seemed to support the hypothesis.

Throughout history there have been reports of decreased memory and mental deterioration that accompanied old age. Alzheimer’s disease (AD) was named after Dr. Alois Alzheimer who described the symptoms in a woman in Germany in the 1907 but it was not until the 1970’s that AD was considered to be a major disorder and AD continues to be a major health concern worldwide (Reger, 2002).

of visual imagery and list type. They believe that imagery could possibly affect false memories in different ways depending on the list item associated.Researchers still have to investigate the outcome of visualizing phonologically. They have even said that investigating phonological lists through meaning could be difficult because they are theorized to happen through sound with phonological lists. Their secondary goal was to assess whether imagery instructions could influence false memories based on the nature of how the memory test is used. The participants of the memory test completed immediate recall tests. They were administered list by list, and at the end there was a final

Dementia, defined by the Alzheimer’s Association, is the overall term for diseases and conditions characterized by a decline in memory or other thinking skills that affects a person’s ability to perform everyday activities. More than 250,000 Americans will develop dementia (including Alzheimer 's) when they are sixty-five or older and at eighty-five the risk of developing Alzheimer’s is fifty percent. Since this disease was found in 1907 by Alois Alzheimer, there have been thousands of dollars, research, and clinical trials put into finding a cure for this horrible disease. This literature review examines the effects of the type of Dementia known as

Dementia is one of the age-related disorders which commonly affect the aging elderly population (65 and over). In 2010, the approximate number of people who had dementia was 35.6 million and it is estimated to double every twenty years, to 65.7 million in 2030 and 115.4 million in 2050 respectively. The incidence of dementia every year is 7.7 million which equals to one new case every four seconds (World Health Organization [WHO], 2012). In 2011, the Canadian baby boom generation initially began to turn 65 and became part of the elderly population which significantly impacted the fertility rates (Rockwood & Keren, 2010). In Canada, the elderly population accounts for approximately 13% of the population and one in eleven has dementia (Stein-Parbury & Eliopoulos, 2014). The researchers have estimated that by 2036, it will account for 25% of the population and 28% by 2061 (Bartfay, Bartfay & Gorey, 2013). There are many forms of dementia that an individual can acquire. Alzheimer’s disease is one of the common forms of dementia in the elderly population (National Institutes of Health, 2013). Currently, approximately five million Americans have Alzheimer’s disease (WHO, 2012) from which two thirds account for women (Alzheimer’s Association, 2014). The reason behind more women having Alzheimer’s disease is merely due to the fact that women have higher life expectancy and old age contributes to higher risk for acquiring Alzheimer’s disease. It is apparent that Alzheimer’s disease

Ritalin, and Adderall, respectively. Although originally developed to treat diagnosed conditions ranging from narcolepsy to attention deficit hyperactivity disorder, their off-label use has been reported to increase users’ recall, attention span, and ability to focus on cognitive tasks; in addition, modafinil has been shown to increase wakefulness (Butcher 2003; greely et al. 2008). Some CEDs also seem to enhance users’ “executive function,” or problem-solving ability (Mehlman 2004, p. 484). Beyond the currently available drugs, research into Alzheimer’s disease and other causes of cognitive decline in the elderly is likely to contribute, intentionally or not, to the further

No significant effect was found for false recall and recognition, p = .20 and p = .94, respectively. There were no significant findings in the Group x List Type for false recall and recognition. There was a significant effect of list type for true recall and true recognition, p = .01 and p = .07.

Alzheimer's Disease is a condition that affects 50% of the population over the age of eighty five, which equals four million Americans each year. It is becoming an important and high-profile issue in today's society for everyone. There are rapid advancements being made in the fight against this disease now more than ever, and the purpose of this essay is to educate the public on the background as well as the new discoveries. There are many new drugs that are being tested and studied every day which slow down, and may even halt the progress of the disease.

In a study, 1,300 patients having mild dementia were grouped into two and given different kind of drugs. One group has been made to take the solanezumab drug and the other patients took a placebo. The trial which lasted for 18 months showed that patients under the solanezumab treatment experienced a 30% decline in memory loss.

With today’s fast paced world advancing every aspect of our daily life, one facet ceases to change—our thought process and the rate at which we learn. As technology continues to advance, consumers also face the inevitable problem of becoming outdated. Ironically much like technology, humans age and eventually lose memory. Therefore, scientists from Quincy Bioscience have developed a revolutionary dietary supplement called Prevagen that will improve one’s memory and enhance brain function. In an advertisement released by Quincy Bioscience, representatives for Prevagen disclose positive results, and yet, without a thorough evaluation from the Food and Drug Administration, (FDA) the credibility of Quincy Bioscience appears faulty at best. In addition,

so I was curious about this pill that claimed it could support memory and improve brain function the pill is called "Prevagen" and makes many claims about what it can do. this was one of the articals I read about this so called "magical pill."
