Alzheimer's Disease
Alzheimer¡¦s disease is a slow, progressive, and degenerative disease of the brain. This disease is marked by a gradual loss of memory and other cognitive functions. "Alzheimer's Disease is also known as the most common cause of dementia--a general term referring to the loss of memory and the ability to think, reason, function, and behave properly" (Medina,1999). It primarily affects adults in their 60's or older and eventually destroys a person's ability to perform simple, routine tasks or even to care for themselves. Statistics show that "as many as 10 percent of all people 65 years of age and older have Alzheimer's," and that approximately "50 percent of all people 85 or older also have the

Today, these certain plaques and tangles found in the brain are considered to be the tell tale signs of Alzheimer's disease.
The cause of Alzheimer¡¦s disease still remains a mystery today. Researchers are learning about what happens to the brain as we grow old, what happens to brain cells in Alzheimer's Disease, which genes are associated, and many other factors that may be significant. Some of the most promising Alzheimer¡¦s research is being conducted in the field of genetics to learn the role a family history of the disease has in its development. Scientists have learned that "people who are carriers of a specific version of the apolipoprotein E gene (apoE gene), found on chromosome 19, are several times more likely to develop Alzheimer¡¦s than carriers of other versions of the apoE gene. Nearly half of all late-onset Alzheimer¡¦s patients have the less common apoE4 version and research has shown that this gene plays a role in Alzheimer¡¦s disease"(Cutler & Sramek, 1996). Scientists have also found evidence that "variations in one or more genes located on chromosomes 1, 10, and 14 may increase a person¡¦s risk for Alzheimer¡¦s disease"(Cutler & Sramek, 1996).
Researchers have made similar strides in the investigation of early-onset Alzheimer¡¦s disease.
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 is a disease of the future. With the growing aged population, this disease, which affects primarily the elderly, will become of increasing relevance to the medical profession. Also, the high frequency of Alzheimer’s, and the high cost in labor, money, and material of caring for its victims shall put considerable burden on the society as a whole. Here, however, these issues are not going to be debated. Instead the pathology of Alzheimer’s will be reviewed to the extent it is known today.
Alzheimer’s Disease is an irreversible, genetically linked illness. This disease was chosen for the topic of this essay under the consideration that in many families the illness can be incredibly tragic, passing down for generations without mercy. It is not rare to encounter families in which each member is afflicted with a form, mild or severe, of Alzheimer’s. The disease is a progressive brain disease which comes in two separate types: Early-Onset Alzheimer’s Disease and Late-Onset Alzheimer’s Disease. These will be discussed in full later on in the paper.
Alzheimer’s is a disease in the brain that affects a person’s memory, thinking, and behavior. It is the most common form of dementia and is common in adults older than 65. More than five million Americans are being affected by Alzheimer’s at this moment. Alzheimer’s comes in three stages; early, middle, and advanced. The disease is caused by the shrinking of the brain due to many risk factors and genetics.

Alzheimer’s disease is a complex illness that affects the brain tissue directly and undergoes gradual memory and behavioral changes which makes it difficult to diagnose. It is known to be the most common form of dementia and is irreversible. Over four million older Americans have Alzheimer’s, and that number is expected to triple in the next twenty years as more people live into their eighties and nineties. (Johnson, 1989). There is still no cure for Alzheimer’s but throughout the past few years a lot of progress has been made.
It is inevitable that eventually each of us will grow old and begin to face more and more health problems as our age rises. Elderly people are challenged by many illnesses and diseases that unfortunately, are incurable. One disease that becomes more common as people age is Alzheimer’s disease. Alzheimer’s a common cause and a form of dementia and can severely damage a patient’s cognitive functions and can ultimately cause death. Living with Alzheimer’s disease can be saddening for both the sufferer and the family. Family and friends will find it very hard to cope when a loved one begins slipping away and losing memory of who they are.
Scientists believed in 1995 that there was a genetic influence in over half the cases of Alzheimer's disease. The gene scientists are giving the most consideration to apolipoprotein E gene (ApoE) as the main gene involved in the development of Alzheimer's disease. Everyone has this gene; if they did not, they would not be alive. ApoE carries a person's cholesterol through their blood. The effect that this gene has in terms of the brain is not totally understood. Scientists have found that
In 1901, a fifty one year old woman named Frau Auguste D. was admitted to a psychiatric hospital in Frankfurt, Germany. She had an unusual bunch of symptoms. While she had no history of prior psychiatric illness, her husband had noticed that Frau D. was becoming increasing paranoid, hallucinatory, agitated, disoriented, and having increasing difficulties with language functions and memory.
The Journal of the American Medical Association reports the latest break through in the study of gene causing Alzheimer’s has pointed to two genes, chromosomes 2 and 19 that cause the disease (7). The article also points out another gene, A polipoprotein E-e4, is also linked to Alzheimer’s disease. According to the Journal of Alzheimer’s disease, Jose Vina and Ana Lloret writes that women are at higher risk of Alzheimer’s due
Alzheimer's is extremely common disease; more than three million people in the United States are diagnosed per year. Every 66 seconds one person in the United States is diagnosed with this scourge. Alzheimer's is a serious disease that affects family and friends as well inflicted sufferer. This dreadful disease make people forget simple task they do daily; a few examples as follows; bathing, using the restroom, and driving. There are many facts that world should know about Alzheimer's.
The research into Alzheimer's Disease has come a long way since 1906 when it is was discovered by Alois Alzheimer. He detected microscopic brain tissue changes called senile and neuritic plaques in deceased patients. These are chemical deposits consisting of protein molecules called Amyloid Precursor Protein(APP) that are fundamental components of a normal brain. However in the brain of an Alzheimer patient, an enzyme cuts the APP apart and leaves fragments in the brain tissue. These combined with degenerating nerve cells cause the plaques or lesions. These lesions are found in many sections of the brain including the hippocampus which regulates emotion and memory, the basal forebrain, and especially the basal nucleus of Meynert and the cortex, where the memory function is located.(2) Another sign of a diseased brain are neurofibrillary tangles, which are malformations within nerve cells.
Alzheimer’s disease is a very slowly progressive disease that occurs inside the brain in which is characterized by damage of memory. Also this type of disease can lead into interruption in language, problem solving, planning and perception. The chance of a person developing Alzheimer’s disease increases enormously after the age of 70 (Crystal, 2009). Also people who are over the age of 85 have over a 50 percent chance of developing Alzheimer’s disease. This type of disease is not at all normal in the aging process and is also not something that happens out of no where in a person’s life.
Although Alzheimer’s disease (henceforth: AD) has been around since the 19th century or possibly even earlier and was at a point in time classified as senile dementia, it wasn’t until 1906 following Dr. Alois Alzheimer’s encounter with Auguste Deter at a Frankfurt asylum that the name of the disease was finally coined. Since then, major developments relating to the disease has taken place. In our report, we addressed some of the areas of the history, contemporary and prospects of the disease.
Alzheimer is a disease that affects the elderly most. The disease was discovered by Dr. Alois Alzheimer in the year 1906 when he was examining a female’s brain. He found out that the woman displayed memory loss, language problems and some inexplicable changes in behavior. The disease was named after the doctor who was a German psychiatrist and a neuropathologist. Alzheimer’s disease is a degenerative brain disorder that leads to memory loss, personality changes, and language problems (Gilbert & Julie 2). The disease is mostly diagnosed in people over the age of 65 years, though there is a small minority of people under the age of 50 who get the disease. Studies show that 1% of a whole population aged between the ages 65-75 have severe
