Is it hereditary? The cause of the disease […]. Average survival time is affected by age at diagnosis and severity of other medical conditions. Family history is another risk factor. Scientists believe that genetics may play a role in many AD cases. It occurs later in life, and no obvious inheritance pattern is seen. However, several risk factor genes may interact with each other to cause the disease.
Alzheimer% 27s disease essays
Everyone has apoE, which helps carry cholesterol in the blood. FDA-approved drugs may temporarily improve or stabilize memory and thinking skills in some individuals. One in 10 individuals over 65 and nearly half of those over 85 are affected. Early diagnosis is very important. Heavy particles are accelerated to a higher energy level of MeV using cyclotron Granov, Tiutin et al.
The beam of particles is focused on the target substance by using radio magnetic lens. The target material is bombarded with heavy particle to generate the required radionuclide Granov, Tiutin et al. The tracers has to be a poor substrate of p-glycoprotein if it has been developed for imaging targets in brain Terasaki and Hosoya It has been found that low hydrogen bonding plays an important role in predicting good PET tracers McCarthy, Halldin et al. For a good tracers, time to binding equilibrium should be long relative to washout of non-specifically bound tracer, but short relative to isotope decay McCarthy, Halldin et al.
Since there is significant overlap between amyloid imaging and CSF- A?? In addition, current hypothesis states that higher amyloid burden assessed by florbetapir 18F 18F-AV amyloid PET is related with lower memory performance among clinically normal older subjects Sperling, Johnson et al.
FDG-PET measures the local glucose metabolism for neuronal activity at resting state to asses cerebral function. It is evident that AD individuals has reduced FDG uptake predominantly in tempoparietal association areas, precuneus and posterior cingulate region Minoshima, Giordani et al. These changes could be observed in subjects from year before the onset of dementia and are closely related to cognitive impairment Herholz Although MRI is more sensitive in detecting and monitoring hippocampal atrophy Fox and KennedyFDG is more sensitive in detecting neuronal dysfunction in neocortical association areas.
Hence FDG is well suited for monitoring the progression of the disease syndrome Alexander, Chen et al. This page of the essay has words. Download the full version above. There are several types of treatments and different types of medications that are used to help patients and some of alzheimer disease essay are used to decrease some of the symptoms that the patients have.
Specialists may be included if the patient and the family agree. Some of the specialist that may be involved are a neurologist and a psychiatrist and geriatrician and occupational therapist. Doing exercise anywhere from minutes 5 days a week increases their health. They may also be given cholinesterase inhibitors these kind of drugs work by boosting cell-to-cell communication by providing a neurotransmitter that is released by the brain that helps with symptoms such as agitation and depression.
It can also help improve their mood, maintain healthy joints, and muscles as well. A: Enhances the effects of a neurotransmitter by blocking an enzyme that is responsible for its breakdown. Even when non-pharmacologic interventions controlling blood pressure, cognitive stimulation therapy, healthy diet and exercise, and maintaining social networks Nelson and Tabet are used as part of a comprehensive treatment plan and initiated early in disease progression, the best that current treatments can offer is to slow the essay about alzheimer s disease progression of the disease.
With AD prevalence expected to increase worldwide across all races and ethnicities, preface in master thesis culture of different populations is an important consideration when designing intervention strategies. Social and economic barriers that prevent access to health care and social services among different populations need to be understood to identify and implement the best treatment specific to that population.
Cultures also differ in how they view AD-related cognitive decline and may consider the memory loss a part of normal aging and therefore delay seeking treatment.
The greatest challenge in developing treatment for AD that can prevent AD development or progression is that a specific cause has not yet been identified. Using a light flickering at 40 hertz, Iaccarino et al.
This may lead to new non-invasive AD therapies, but more research is needed to investigate its effectiveness in humans. Amgen and novartis announce expanded collaboration with banner alzheimers institute in pioneering prevention program.

Estimates vary, but experts believe as many as 5. It regulates the sensory, alzheimer s disease essays and motor function of the body. Everything we do, feel or think is directly linked to the Nervous System. An error in any of these functions could bring negatives consequences such as degenerative diseases later in life. About Essays Essays FlashCards. Browse Essays.Also, research is being conducted in the area of Alzheimer's itself and the disease's progression.
One set of researchers has found that Alzheimer's patients, while being aware of their deficits in memory and other function in the beginning of the illness, lose some of this self-awareness as the disease progresses. This self-awareness is most likely, logically, connected to the fact that an Alzheimer's memory deteriorates as the disease progresses -- a patient cannot be aware of things they do not remember Derouesne et all, In addition, many more areas are being researched in regards to dementia and Alzheimer's disease.
In fact, there are so many that it is beyond the scope of this paper to discuss them all. However, some of these are worth mentioning. For example, significant findings from studies have improved doctors' understanding of the plaques and tangles seen in the brains of individuals with Alzheimer's disease.
This understanding eventually may lead to the development of treatments to slow the effects of the disease process. Ultimately, the prevention of the plaque deposits and tangles is the goal of this research.
Moreover, the recent discovery of a previously unknown lesion characteristic of Alzheimer's disease may lead researchers to further understand the disease process and how intervention therapies may be designed. This lesion, called AMY plaque, may play a role in the onset and progression of Alzheimer's.
Moreover, studies of the inflammatory processes of the brain and the role of oxidative stress in Alzheimer's disease have been conducted. This has led to preliminary indications of the beneficial use of anti-inflammatories, such as ibuprofen, and antioxidants, such as vitamin E, in treating or slowing progression of the disease. As of yet, there are no known cures for Alzheimer's disease.
In fact, many of the dementias similar to Alzheimer's also lack a cure.
However, research is continually being conducted. This research covers a wide range of areas, from better diagnostic tools to genetic testing. One such diagnostic tool recently received a patent. According to the inventor of the tPST, H.

A complete medical examination for memory loss may include gathering information about the person's medical history, including use of prescription and over-the-counter medicines, diet, past medical problems, and general health.
The doctor also may alzheimer disease essay a family member for information about the person. An AD support group is crucial to alleviating some of the stress on the care giver. Through a support group the care giver is given the emotional and practical help needed to accomplish the large task of looking after the victim for as long as possible. Currently there arepersons in Canada with AD.
This figure is more than that of Parkinson's disease, cancer and multiple sclerosis combined. With continuous growth in the percentage of Canadians over the age of 65, this figure could hitby the year Carlton,p.
These patient care essay and increasing figures translate into a large burden on the health care system. Even when using the most conservative estimates of the average number of years spent in an institution and the number of afflicted Canadians, the costs to health care are immense.
A very high incidence was reported in a U. AD is a democratic disease. It affects persons of both sexes and all races and ethnic backgrounds. The major risk factors for AD are age and heredity. Persons with a high incidence of AD in their family history are most succeptable. A specific subtype of AD exists that is solely connected to heredity. FAD is also known as Early Onset Alzheimer's disease, named so because its symptoms start to develop much earlier than in the regular sporadic type.
FAD is suspected when AD can be traced over several generations and there is a history of, among previously affected family members, a similar age of onset and duration of the disease usually 4 years. Much research has been conducted in an attempt to locate the gene that is responsible for FAD. Currently, researchers have isolated genes 1, 14, and 21 Alzheimer's,p. There is also a possibility that a specific genetic mutation merely puts a person at risk to the disease and AD is triggered by an external force e.
Finding the specific location of the gene will pave the way for a diagnostic or even predictive test for FAD. Similar genetic tests already exist for cystic fibrosis and muscular dystrophy.
Treatment Of Alzheimers Disease And Dementia Psychology Essay –
Locating the AD gene will also allow scientists to study why the particular gene is not functioning properly and may give clues to treatment and cure. The long term goal of this research is the same as that of any other genetic research and that is gene therapy - which is the possibility that science could one day alter our genetic make-up.
This includes all other types of the disease which are not linked to heredity. The most common symptom is remembering new information. The person may not know that they have it so if they are showing symptoms it is best to take them to see a doctor and have them checked out. They will become more aggressive and will ask repetitive questions. As the severity of the disease progresses patients tend to forget the time and day. Everyone tends to forget what they had to say or what to do of course ever once in awhile.
They may also forget important appointments and not remember them at all. They may often misplace things, alzheimer disease essay usually putting them in irrational locations such as under their bed or in the refrigerator. Patients sometimes will seem to get lost in casual places.
