Alzheimer’s disease is a devastating neurodegenerative disorder manifested by deterioration in memory and cognition, impairment in performing activities of daily living, and many behavioral and neuropsychiatric illnesses. The pathological hallmark of Alzheimer’s disease is widespread neuritic plaques which are accumulations of amyloid beta protein and neurofibrillary tangles. Studies report that deficit in cholinergic system is responsible for cognitive decline and memory loss in patients with
Alzheimer’s disease. Various pharmacologic approaches are developed for the treatment of Alzheimer’s disease. The leading edge therapies of Alzheimer’s disease are approved drugs; Acetylcholinesterase inhibitors and NMDA receptor antagonist. The experimental therapies are mostly disease modifying and have neuroprotective approaches. Gamma secretase inhibitors aim to reduce amyloid beta formation.
Antioxidants, antiinflammatory agents and statins help by preventing oxidation and inflammation.
PPAR gamma agonists, estrogen, heavy metal chelators, 5HT6 antagonists and nicotinic receptor agonists are other therapeutic strategies likely to alter the current treatment paradigm of Alzheimer’s disease. The behavioral abnormalities are best treated first by non-pharmacologic interventions. The pharmacological agents used for treatment of Neuropsychiatric illnesses include antipsychotics, antidepressants and mood stabilizers. Treatment of Alzheimer’s disease also includes health maintenance activities and proper nursing care of the patients.

    Dementia? Why Is Alzheimer Disease Based On A Diagnosis Of Exclusion?

    Grossman and Porth (2014), states that neurochemical changes in the brain are effected by Alzheimer’s disease and are the main cause of memory loss. Particularly, the level of choline acetyltransferase activity in the cortex and hippocampus is decreased. This is an enzyme that is required in order for acetylcholine (a memory neurotransmitter) to be synthesized, making the decrease in choline acetyltransferase enzymes quantitatively related to a large number of neuritic plaques (Grossman & Porth, 2014). According to the Alzheimer’s Association (n.d.b), the cortex shrivels up damaging the areas involved with thinking, planning, and remembering; the hippocampus (part of the cortex) also shrinks, which plays an imperative role in the formation of new memories.…

    HCS 245: A Case Study Of Alzheimer's Disease

    Alzheimer’s disease is the most common form of dementia, a neurologic disease characterized by loss of mental ability severe enough to interfere with normal activities of daily living, lasting at least six months (Deirdre, Blanchfield, & Longe, 2006). At first Alzheimer’s disease will destroy neurons in parts of the brain that control memory. As these neurons stop functioning, the short-term memory will continue to deteriorate. Later the disease affects the cerebral cortex, mainly the area responsible for language and reasoning. These language skills are lost and the ability to make judgments is changed. The severity of these changes increase…

    Alzheimer’s Disease Wendy Raney Walden University NURS 6501, N-19, Advanced Pathophysiology May 10, 2015 Alzheimer’s Disease (AD)  Alzheimer’s disease is an irreversible and progressive disease of the brain that gradually destroys thinking and memory skills. The disease eventually leads to the inability to carry out simple activities of daily living. Pathophysiology  There are 3 forms of AD: early-onset, early-onset familial, and lateonset  Early-onset familial AD is linked to mutations of 3 genes on chromosome 21: abnormal amyloid precursor protein 14 (APP14), abnormal presenilin 1 (PSEN1), abnormal presenilin 2 (PSEN2)  Late-onset AD is possibly related to a link between chromosome 19 and apolipoprotein E gene-allele 4 (APOE4) (Huether & McCance, 2012) Pathophysiology Continued  Abnormal deposits of proteins lead to the formation of neuritic plaques and tau tangles throughout the brain.

    Dementia: Cerebrum and High Blood Pressure

    1.Understand what dementia is 1.1 Explain what is meant by the term 'dementia' A syndrome due to disease of the brain, usually of a chronic progressive nature in which there are multiple disturbances of higher cognitive function. These include impairment of memory, thinking and orientation, learning ability, language and judgement. 1.2 Describe the key functions of the brain that are affected by dementia The key functions of the brain that are affected by dementia are the temporal lobe, frontal lobe, parietal lobe, occipital, cerebrum lobe and the hippocampus. Temporal lobe- responsible for vision,memory, language, hearing and learning Frontal lobe- responsible for decision making, problem solving, control behaviour and emotions Parietal lobe- responsible for sensory information from the body, also where letters are formed, putting things in order and spatial awareness. Occipital lobe- responsible for processing information related to vision Cerebrum lobe- is responsible for for the biggest part of the brain its role is memory, attention, thought and our consciousness, senses and movement. Hippocampus- responsible for memory forming, organizing and storing and emotions 1.3 Explain why depression, delirium and age-related memory impairment may be mistaken for dementia Because they both manifest with similar symptoms. Depression coupled with age related memory impairment looks the same as dementia to the untrained eye. The difference is that depression delirium responds to treatment with anti depressants, once you get on top of the depression you can put age related memory loss into perspective. If it is genuine dementia it won't get any better. 2.Understand key features of theoretical models of dementia 2.1 Outline the medical model of dementia The medical model focuses on the impairment as the problem and focuses on a cure, these may be dependency, restriction of choice, dis empowering and devaluing individuals 2.2 Outline the social model of…

    Still Alice: Modern Day View Of Alzheimer's Disease

    The movie I watched for assignment 1 was Still Alice. This movie represents a modern day view of Alzheimer’s Disease and the rapid deterioration and destruction that this disease can have one’s life and family. The main character Alice was a professor of linguistics at Columbia, at the age of mid to late forties, she started to notice that she was losing her train of thought and her memories. She was finally diagnosed with the deadly early onset Alzheimer’s that was passed through her family genes. Within nine months of the diagnoses she lost the ability to think, to remember important dates and people, and became a hollow shell of herself. Overall, I enjoyed this movie, it was heartbreaking however, the story line does incorporate real facts about what happens to one’s self and family when one is diagnosed with this disease. Still Alice truly captured “the art of losing” in a sense that many in the United States have witness or are aware of.…

    Explain Whether Cognitive Ability Is Modifiable In The Older Adult

    According to Larkin (2015), growing older is accompanied by loss of memory and decline in thinking and problem solving. Moreover, inability to learn and eventually dementia. One example of this cognitive decline is dementia or Alzheimer’s disease. Cognitive ability is modifiable through various brain stimulation such as, work related activities has a positive effect on cognitive aging. Change in many of myriads, both biological and psychological and cognitive. Some may be for better, and some are not. There is evidence that alterations in brain structure and function are a tie to change in cognitive function. Executive function is a key contributor to age-related declines in a range of cognitive tasks. For example, attention in the primary cognitive process seems to decrease in elderly patients. The ability to process information also decline. Working memory is also linked to an age-related deficit in a verify of cognitive task including long-term memory, language, and problem-solving. Cognitive function declines with aging especially the domains related to memory and information processing and speed changes in cognitive performance. Modifiable risk factors for the age-related cognitive decline have been identified, but their causality has not yet established. Poor folate status is one such suspected factor (Glisky, 2007). For example, an elderly patient may forget events that occur yesterday or where they leave keys or purse.…

    Korsakoff's Syndrome

    Korsakoff’s syndrome is a disorder in which a lack of thiamine results in anterograde and retrograde amnesia — those with the disorder exhibit the loss of newly formed memories, and a degeneration in their ability to remember events from their past (Spiegel, Lim, 2011, p. 15). Found generally in alcoholics, the combination of their compromised metabolism and thiamine deficiency results in Wernicke’s Encephalopathy, which then progresses to Korsakoff’s syndrome (Thompson, Guerrini, Marshall 2012, p. 81). Interestingly, as opposed to having a general loss of memory across their lifespan, some studies have found a relative preservation of memories from childhood and early adulthood in people presenting with Korsakoff’s syndrome (Race, Verfaellie, 2012, p. 105).…

    Examples Of Alzheimer's Disease In African American Culture

    In the 1960s, scientists discovered a link between cognitive decline and the number of plaques and tangles in the brain. The medical community then formally recognized Alzheimer’s as a disease and not a normal part of aging. In the 1970s, scientists made great strides in understanding the human body as a whole, and Alzheimer’s disease emerged as a significant area of research interest. This increased attention led in the 1990s to important discoveries and a better understanding of complex nerve cells in the brains of Alzheimer’s patients. More research was done on Alzheimer’s disease susceptibility genes, and several drugs were approved to treat the cognitive symptoms of the disease.…

    Neuropathological Disorders

    With Alzheimer’s disease damage to the brain can begin up to ten to twenty years before any problems are evident. Alzheimer’s leads to nerve cell death and tissue loss throughout the entire brain. Over time the brain begins to shrink. In Alzheimer’s patients the cortex shrivels up, which damages areas involved in thinking, planning and remembering (Brill, 2005). The shrinking is severe in the hippocampus, which is what plays a key role in forming new memories in the brain (Brill, 2005). As these areas shrink, ventricles, which are fluid filled spaces within the brain, grow larger. In studying the brain of Alzheimer’s patients they have also found that their tissue has fewer nerve cells and synapses. Plaque, abnormal clusters of protein, builds between nerve cells and dead and dying nerve cells contain tangles, which are twisted strands of another protein (Brill, 2005).…

    Discovery Of Alzheimer's Disease

    The history of Alzheimer's Disease was first discovered by Dr. Alois Alzheimer in the early 1900's. After a woman had died Dr. Alzheimer examined her brain and discovered changes in the brain, which are still today used to detect Alzheimer’s Disease. When he made this discovery, at this point of history Alzheimer's Disease was only found in people under the age of 65 years old. Jorm notes, "Because it occurred in people who had not reached the conventional point of old age, it was described as a presenile dementia. At his time, dementias occurring in the elderly were labelled as senile dementia" (pg. 6). With more and more studies and autopsies of the brain they noticed that the disease was just a slow process and wasn't noticeable until after…

    Cognitive Disorder

    Cognitive disorders are a category of mental health disorders that primarily affect learning, memory, perception, and problem solving, and include amnesia, dementia, and delirium. While anxiety disorders, mood disorders, and psychotic disorders can also have an effect on cognitive and memory functions, the DSM-IV-TR does not consider these cognitive disorders, because loss of cognitive function is not the primary (causal) symptom. Causes vary between the different types of disorders but most include damage to the memory portions of the brain. Treatments depend on how the disorder is caused. Medication and therapies are the most common treatments; however, for some types of disorders such as certain types of amnesia, treatments can suppress the symptoms but there is currently no cure.…
