Among them, population data indicate that 520,000 people have AD with 423,000 people live in England and 26,000 people live in Wales [1]. Incidence of AD among people aged 65-68 years is estimated to be 7.4 per 1000 person-years and this incidence escalate to 84.9 per 1000 person-years at people over 85 years old [1].

    ‘Dementia is an umbrella term used to refer to a collection of symptoms that can result from a number of different diseases of the brain’ (BBC, 2013). The progressive deterioration in cognitive function that is synonymous with dementia tends to result in confusion, memory loss, impaired language skills, communication and information processing difficulties, in addition to unreliable judgement (NHS, 2013). 820,000 people in the UK currently have a diagnosis of dementia and it mainly affects those over the age of 65 with a prevalence of 4.61% in the male population aged 70-74 (Alzheimer’s Research UK, no date). It is estimated that approximately 1 million people will have been diagnosed with dementia by 2021 (Alzheimer’s Society, 2013). Unfortunately, dementia is a progressive disease, for which there is currently no cure. This means that Winston’s existing symptoms of confusion and forgetfulness will gradually get worse and will eventually result in death (World Health Organisation, 2012). Notwithstanding, those diagnosed with dementia are often offered medical and psychological treatments that are designed to either delay or improve the more debilitating aspects of the disease (NHS, 2013). As dementia progresses, memory loss and difficulties with communication often become more severe. The latter stages of dementia result in the likelihood of the individual neglecting their own health and requiring constant care and attention. This can lead to the individual being unable to…

    Moore, Elaine A, and Lisa Moore. Encyclopedia of Alzheimer 's Disease: With Directories of Research, Treatment and Care Facilities. Jefferson, N.C: McFarland, 2012. Print. This piece of text is very informational in the way it describes Alzheimer’s and the places where a patient can go for help and therapy. The text explains everything about Alzheimer’s and it helps the reader to further understand what the disease actually entails. The encyclopedia is very descriptive, but it can be bland and dry. Since it is an encyclopedia, there are a lot of graphs that try to help the reader relate the information portrayed through a graph. The text is decent, however, it is very informational and boring to read. It is useful for those who want to the complete understanding of what Alzheimer’s is. Although it is useful, it is not a particular text that you would want to spend your Saturday afternoon reading. It is a reliable source because it is an encyclopedia and it has been revised multiple times before it has been published.…

    Approximately 5.4 million Americans now have Alzheimer's disease and by the year 2050, more than 15 million Americans could possibly be living with the disease, unless scientists or medical professionals develop new ideas to prevent, slow or cure it. (AHAF) Alzheimer’s is usually associated with old age but it can also be diagnosed in younger individuals. “Alzheimer's disease is the sixth-leading cause of death in the United States and the only cause of death among the top 10 in the United States that cannot be prevented, cured or even slowed.” (ALZ) This is considered to be one of the most heartbreaking diseases for a loved one to go through, because you’re basically watching them mentally fall apart often to the point when they don’t even remember who you…
