Manifestation And Etiology

Alzheimer disease (AD) is the most common cause of dementia in the elderly, accounting for 65–70% of all cases (Jellinger, Janetzky, Attems, & Kienzl, 2008). The other dementias are of the Parkinson 's group, the fronto-temporal group and the vascular group. The total worldwide yearly costs for the treatment and care of patients suffering from dementia are estimated to be around 250 billion US dollars. The lifetime risk for AD between the ages of 65 and 100 is 33% for men and 45% for women with an annual increase of 1–2% in the seventh decade to almost 60% in the 10th decade with doubling every 5 years (Jellinger et al., 2008). AD is incurable, and thus represents a major public health problem. AD represents a challenge to humanity due to its relatively recent discovery, progressive nature of the illness, and complex diagnosis.

Alzheimer’s disease (AD), a form of degenerative, fatal dementia, is characterized by progressive cognitive decline. While AD is the most common form of dementia, its prevalence has only recently been recognized. When Alois Alzheimer first described the sequence of changes in 1907, physicians believed the disease to be an extremely rare, mid-life condition. It wasn’t until the 1970’s that the same types of changes were shown to occur in both late- and early-onset forms (Cavanaugh et.al. 2008). As such, almost all knowledge of AD has been learned within the past several decades, with new discoveries being reported almost daily. It is now estimated that Alzheimer’s accounts for as many as 60% of all dementias and affects more than 500,000

Alzheimer’s disease is a common problem in today’s society and within the older population this disease makes up the largest form of dementia. Although it is a problem in mainly older people, this disease can still occur in the younger population also. People in their 30s-50s can be diagnosed with this disease, even though it is not as common as people in their 60s-90s. The number of people with Alzheimer’s in the U.S. is close to five million and is expected to double within the next 30 years. With our modern medicine and advancements one would think a cure would be available, however, getting to the cause of the disease is a major factor. The cause of Alzheimer’s disease is one that is very debatable and questionable and most likely is a result of multiple factors rather than one. The main issue with finding the cause is because this disease affects the brain and can

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

One of the most prominent and perhaps most feared condition associated with aging is dementia. The family of disorders can cause individuals to lose their mind, reducing one from being a complex, thinking, feeling human being to being confused and vegetative, unable to recognize their loved ones. Serious dementia affects nearly 37 million people globally, but predictions of how those numbers will change over the next few decades are conflicting (textbook). Although we know dementia as to do with damage to nerve cells in the brain, there are ongoing studies looking at correlations between other health issues and these types of diseases.

Alzheimer’s disease (AD) is a progressive and fatal form of dementia, frequently seen in the elderly altering their cognition, thought process and behavior. AD is reported in about half of patients that have a dementia diagnosis; one study states that about 10.3% of the population over 65 years is affected by dementia with an increase to almost 50% over the age of 8 (Beattie, 2002). Alzheimer’s disease is not a normal part of the aging process in humans, but rather found in a group of diseases that affect the brain leading to a decline in mental and physical control. AD when diagnosed has a very slow and gradual course, initially affecting the individual’s short term memory (Beattie, 2002). Alzheimer’s disease is the 6th leading cause of death, affecting more than five million people in the United States and is also one of the most common forms of dementia. Dementia can be defined as a disorder of progressive cognitive impairment severe enough to affect daily functions of an individual’s life (Fillit, et al., 2002).

The most common tendency in assessing patients who display signs of dementia is to evaluate them for Alzheimer’s Disease. This means that Vascular Dementia, Dementia with Lewy Bodies, and Parkinson’s Disease Dementia are conversely overlooked as possible diagnoses. Special attention to clinical presentation and the use of diagnostic tests (such as the MRI) and assessment scales (like the Mini Mental State Exam) aid in distinguishing between these diseases, and therefore better the evaluation process. There are other telltale markers that aid in assessing these diseases, as well. Alzheimer’s Disease often presents with a slow decline in memory, while Vascular Dementia patients experiences sharp declines in cognition. Patients suffering from Parkinson’s Disease Dementia and Dementia with Lewy bodies often present with symptoms of psychoses and hallucinations as well as cognitive impairments, and they differ in the onset time of dementia. The early detection of cognitive decline is important not only for the treatment but also for improving the caregiver burden of these patients. Management of these disorders is focused on symptomatic relief, but it is also important to minimize life style risk factors for all dementias.

(Alzheimer’s Association, 2016). The severity ranges from just memory loss, to the inability to carry a conversation or respond to the environment. That being the case, Alzheimer’s, or Senile Dementia, is an “irreversible and progressive brain disease” caused by the destruction of neurons, and development of amyloid plaques and neurofibrillary tangles in the brain (ADERF, 2016). Scientists have realized through their research with genetics that genes are crucial to the progression Alzheimer’s. Furthermore, the search for genetic variants will help to determine precision medicine, that takes individuals variability in genes, environment, and lifestyle into consideration. (ADERF, 2016). The probability of finding a treatment for Alzheimer's has boomed since the creation of genetic testing. Thus, the stigma that Senile dementia is an “irreversible and progressive brain disease” may soon to be found

More than five million are living with Alzheimer’s disease in the United States and the number is set to almost triple by the year 2050. It is common in the elderly and generally occurs in persons over 65 years of age, but early onset of Alzheimer’s has also been documented (“Alzheimer’s disease facts,” 2016, para. 1). It starts in the medial temporal area of the brain, usually in the hippocampus, and then spreads to other areas of the brain. Blows (2011) explains, “Alois Alzheimer was a German psychiatrist who in 1906 described a dementia with two specific changes found in the brain after death... these changes were the presence of extracellular plaques and intracellular neurofibrillary tangles and these became the hallmarks of this disease” (p. 286). Loss of neurons takes place and amyloid plaques form. This is due to build-up of non-functioning proteins and can be observed by imaging techniques (Radin, 2003, p. 41). There are many risk factors that increase the risk of Alzheimer’s disease. The greatest risk factor is family history, but other risk factors include diabetes, hypertension obesity, hyperlipidemia, smoking, depression, physical inactivity, low estrogen levels, and head trauma (Huether & McCance, 2014, p. 546). The actual cause of Alzheimer’s is unknown, but there are genes associated with it that make the disease heritable. What is clear is that

Alzheimer’s disease is the most common form of dementia, which slowly and steadily impairs the mental function and psychological competence. Even though there is no cure for Alzheimer’s, current treatment patterns and research aim to delay the progression towards dementia and the associated symptoms. The strongest risk factor for this disease is increased age, typically seen in individuals over the age of 65, but it must be noted that Alzheimer’s is not a normal part of the aging process.

Alzheimer’s is a form of dementia that causes memory loss, thinking, and behavioral issues. Nearly 5.4 million American’s are affected by Alzheimer’s. People who are affected begin with early-onset Alzheimer’s. One will experience symptoms such as confusion, mild memory loss, and speaking issues. The inheritance pattern of early-onset Alzheimer’s is autosomal dominant inheritance. This means that if you inherit the abnormal Alzheimer’s gene from a parent, you are likely to get the disease. Even though Alzheimer’s is a somewhat common disorder, the inheritance pattern of late-onset Alzheimer’s is still unknown. Although, scientists believe genetic, environmental, and lifestyle factors play a role in a person’s risk for developing the disease.

Alzheimer’s Disease (AD) is a progressive and neurodegenerative form of dementia that causes problems with memory, thinking, reasoning, judgement and decision-making, recognizing, as well as behavior, and is serious enough to interfere with daily life and activities, that eventually leads to profound physical as well as mental disabilities, resulting in the need for institutional care (Hoyer & Roodin, 2009). AD is most widespread in senior population aged 65 and over, which constitutes approximately 85-95% of the cases, in the rest of 5-15% of the times Alzheimer’s Disease can have an early-onset (before 60 years of age) (Hoyer & Roodin, 2009). According to Alzheimer’s Association, today Alzheimer’s Disease is at the forefront of biomedical research, as it is the sixth leading cause of death in the United States (alz.org). Researchers hope that better understanding of Alzheimer’s and related dementias can lead to discovering new and effective treatments. United States is not the only country that is facing this issue, this problem is global. According to the recent epidemiological studies, the worldwide prevalence of Alzheimer’s Disease will rise from 27 million people worldwide in 2006 to 66 million in 2030, and 115 million in 2050 (Werner, 2012). The main risk factor for developing AD is chronological age (Hoyer & Roodin, 2009). This means that by 2050, one in three persons over 80 years of age will most likely suffer from some sort of dementia, most likely from AD

Alzheimer’s disease is a degenerative, cognitive disease that affects 5.2 million people in America. Many specialists have concerns because our society is living longer. It’s imperative we understand this disease because of the multitude of people it affects. A defining factor of this disease is that it becomes severe enough to inhibit activities of daily living. There are three distinct types of Alzheimer’s: early onset, late onset, and familial. Late onset is what most people think of when they think of Alzheimer’s as it mostly occurs after the ages of 65. Early onset, as the name implies, occurs before the age of 65. This form of Alzheimer’s occurs highly in people with Down’s syndrome. Familial is an inherited form of Alzheimer’s. This

Another clue may be the effects the aging process has on the brain as it is harming the neurons in the brain causing the disease (NIA, 2012). Regardless of the cause, AD is a life altering disease in every aspect of the victim’s life.
