Alzheimer disease is a form of dementia caused by the destruction of brain cells. Alzheimer disease currently affects 60-80% of all cases of dementia, and people over the age of 70 are at a greater risk of developing it (“Alzheimer’s Disease”, 2011).
History of disease:
Alzheimer’s disease was named after the German physiologist who first introduced dementia’s neurological characteristics in 1906 (Jia, 2014). Alzheimer’s disease is a progressive brain disease that destroys the memory and thinking skills of the affected person. Although Alzheimer's is usually considered a disease of the elderly, early-onset Alzheimer's is still possible in people younger. It’s also important to be as healthy as you can in your younger years, as people with

Once Alzheimer’s starts to progress, symptoms can change to the person becoming more difficult with refusing to do basic activities like bathing or sitting down. They also show signs of poor judgment and difficulty speaking and basic comprehension (“Alzheimer’s Disease”, 2011). Those who suffer from Alzheimer's forget the people and places they know because of the deterioration of their minds. The brains of Alzheimer’s patients are beginning to lose connections between the nerve cells in their brain. Without these specific connections, the neural function becomes weaker and the neurons will die out and damage will eventually spread around the rest of the brain. It’s important for early screenings for people over the age of 65. Doctors use exams like MMSE or the Mini-Mental State Examination, where they can measure the patient’s long and short term abilities as well as their communication abilities (“Alzheimer’s Disease”, 2011). Doctors can also ask patients to various other perform tasks that test their attention and problem solving skills as well as ask them about any recent changes in they have noticed cognitively or socially. It is also important that the doctor does a careful evaluation since there may be various other reasons as to why these patients are having these symptoms such as diabetes that has not been previously diagnosed …show more content…
The damage of late diagnosis of Alzheimer’s is that it has already started to spread to the hippocampus, a region of the brain essential to the formation of memories. Alzheimer’s disease is a neurodegenerative disorder that destroys the b-amyloid plagues and neurofibrillary tangles that is important for any type of neural connections in our brain. As the patient’s neuron death increases, the affected region of the brain shrinks (Jia, 2014). By the end stages of the disease, the damage is widespread throughout the brain. It is important for members to be educated about the disease so that they will be able to make plans for the future needs of the patient. It allows the family to make any necessary arrangements and plans for nursing home care if appropriate or at home care if possible as this disease
Dementia is a serious disorder caused by a variety of brain illnesses which affects a person memory .There are three symptoms stages which are early,middle,and late stages. A Person with dementia lose the ability to think well enough to do everyday activities or solve problems. It is also difficult for a person with dementia to interact with others which makes this disease overwhelming for the families of the Patient. The number of people who have dementia is currently estimated at 47.5 million.
It provides the opportunity for prompt evaluation of the patient and possibly administer tests and treatments for reversing and determining the causes of memory loss. In addition, early diagnosis provides time for patients and families to prepare for the future and most importantly it maximizes the patients opportunity to contribute to their own care planning process. As previously stated, the diagnosis of dementia most commonly takes place in the primary care setting. During primary care visits with older or elderly people the interactions tend to be brief and patients often present multiple health conditions that they are experiencing. It can be challenging for the physician to pin point those intersecting health concerns with Alzheimer’s if they are not properly trained to do so.
The Role of Memory in Dementia Acquiring knowledge about how our brains function and all the different problems that it encounters within and between the many stages of life is becoming increasingly important. We are constantly striving to improve the life expectancy of man, meaning that researchers and scientists are working hard to explore and document the human body and what can happen to it. The brain, however, is still relatively mysterious. An increased lifespan means that complex diseases and syndromes that affect the brain have become common occurrences; so much, that we have defined an umbrella term for some of these diseases: dementia. What exactly happens to someone who suffers from dementia?
Sometimes, dementia may have similar symptoms with other psychiatric diseases; however, medical specialists have developed a complex system to identify this illness. National Institute for Neurologial and Communicative Disorders and Stroke-Alzheimer’s Disease and Related Disorders Association define dementia based on the following criteria: 1) decline in cognitive functioning; 2) low score on the neuropsychological test; 3) neuropsychiatric dysfunction in minimum two cognitive areas; 4) absence of delirium (Zahdi and Ham 59). The first criterion is crucial. In order to obtain the detailed history of decline in the patient’s cognitive functions, the specialists should interview a person who has known the patient for a relatively long time and can share detailed information about the person’s cognitive disabilities and the time they started. Such cognitive dysfunctions may include
The condition is progressive and worsens over time; in the later stages, people with dementia become unable to carry out everyday activities and find it difficult to convey their thoughts and feelings. As the symptoms become more profound, they
Dementia is a disorder which causes the brain cells to deteriorate therefor causes a decline in several symptoms and affects a person’s mentality, capacity and how they go about their everyday life. NVQ 1.2 2) Describe the functions of the brain that are affected by dementia. There are many brain functions affected by dementia depending on which form of dementia the individual has. The temporal lobe’s functions affected are Memory loss for example forgetting things you have just been told or something you have just said so repeating yourself several times, balance, posture and vision can also be affected due to decline in health of the temporal lobe. Frontal lobe affects behaviour for example becoming withdrawn.
Adeline has had Alzheimer’s disease for six years now; she has been fighting hard but her disease is only getting worse. Her family has done all they could, getting her medicine, caregivers, and showing her great care themselves; but nothing will cure her dreadful disease. Her family is watching her slowing fall, further and further away each year, coming to realize one day they will lose their beloved Adeline to this horrific disease. Adeline no longer recalls who her grandchildren are, but her grandchildren and numerous others will forever remember her. Alzheimer’s disease is a “progressive mental deterioration that can occur in middle or old age, due to generalized degeneration of the brain.
According to Greene (2007), there are various forms of Dementia, however Alzheimer’s is most popular affecting families in later life normally 65 years and older degenerating brain tissue over time. Greene further states social workers may be first responders to the discovery of the disease existence through a series of answered questions surrounding the client’s mental status. The disease itself impairs intellectual and cognitive reasoning and is therefore reported to qualified specialist. Learning about the disease will assist with certainty in diagnosis giving way to improving the client and family situation for adjusting, interventions, or advance directives. At any rate, the nature of disease also brings great concerns to caregiving.
Introduction Alzheimer’s is a chronic neurodegenerative disease that usually starts slowly and gets worse over time. The most common early symptom is difficulty in remembering recent events or short memory loss. As the disease advances, symptoms can include difficulty with language, disorientation, mood swing and behavior problems. As a person 's condition progressed, they often withdraw from friends and family. Slowly, bodily functions deteriorated and eventually death occurs.
Patients should not know if they are diagnosed with Alzheimer’s disease because the test could have been inaccurate. Knowing ahead of time about Alzheimer’s could be a burden and give one stress. One finding out too early about
Alzheimer’s is a progressive, degenerative and fatal disease that has different stages. The disease having an emotional, physical, and financial impact on both the person affected with the disease, and the person 's family. Early diagnosis is the key to fighting the disease. As the population of elderly people grows, the problem of Alzheimer’s disease is only getting bigger. Although fatal, early
Literature Review: According to the study conducted by Glickstein (1997), Alois Alzheimer was the person who identified the Alzheimer disease for the first time in 1906. Alois Alzheimer was a doctor and he identifies the Alzheimer disease in his patient (Auguste. D.) who was showing symptoms of paranoia, psychological changes and loss of memory. During the autopsy of the patient, Dr. Alois Alzheimer observed the shrinkage in brain cells and around the brain cells. In earlier days after the discovery of the Alzheimer disease, no treatment was given to Alzheimer’s patients because loss of memory or Alzheimer disease was considered as a natural process which happens with every individual.
Dementia is one of the most feared diseases and expensive to society currently. It is defined as a clinical syndrome of acquired cognitive impairment that determines decrease of intellectual enough capacity to interfere social and functional performance of the individual and their quality of life. It is a known fact that patients tend to express themselves through their behaviour and expect their carers to understand this notion. The diverse kinds of causes of different behaviours are inability to communicate, difficulty with tasks, unfamiliar surroundings, loud noises, frantic environment, and physical discomfort. Many diseases can cause dementia, some of which may be reversible.
AD progression & diagnosis The progression of Alzheimer's can be described through several main cognitive stages starting at no cognitive decline through too mild to moderate before progressing to a more severe form of the disease. The pathological process associated with AD occurs roughly 20-25 years before symptoms appear (Mullane & Williams 2013). When symptoms become predominant Alzheimer’s can be diagnosed through a standardized scale (Mini-Mental State Exam) or questionnaire (Functional Activities Questionnaire) which is used to assess cognition (Desai & Grossberg 2005). Increasingly neuroimaging such as CT, MRI or PET scans are being suggested and used as a means to screen and diagnose for Alzheimer’s (Avila 2006; Borson et al. 2013).
An increase in distribution and density of both amyloid plaques and NFTs was seen from MCI to LAD. Use of imaging techniques such as MRI, demonstrates the varying degrees of degeneration in all stages of clinical AD, where MCI presents a relatively small degeneration affecting the Hippocampus, Sulci, And Gyri, whereas LAD affects the same regions to a greater extent and this is accompanied by additional atrophy of the frontal lobe and ventricular widening in EAD and LAD. PET scans revealed a significant reduction in the glucose utilization within the brain of AD patients indicating a severe energy deficiency (Butterfield, Swomley, & Sultana, 2013). 1.3 Changes in the brain: Alzheimer’s disease strikes certain brain parts first, like the limbic system, primarily the hippocampus, followed by the cerebral cortex, then the brain stem, causing the loss of function in these structures and the symptoms are a direct result of this sequential damage: 1. Damage to the Limbic system (hippocampus, amygdala, thalamus, and more) impairs memory and causes mood swings.
