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.

    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.

    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…

    1.3The abilities and limitations affect the way information is processed in many ways. The chemical Dopamine controls the flow of information from other areas of the brain, particularly memory and attention and an imbalance will cause information to not flow correctly. Serotonin has an effect on mood, anxiety and depression, and so it is expected that an individual with dementia will have difficulty in those three areas, for example erratic mood swings and the inability to maintain a constant mood, well-being or self-esteem. Acetylcholine control the activity of the brain that connect with attention, learning and memory – Alzheimer’s sufferers experience major difficulty with these areas due to having a low level of ACh in their brain. Glutamate makes the links between neurons that are the centre of learning and long-term memory, without it or a decreased amount of it, the neurons are unable to transmit information properly. Also in addition, people with dementia with neuron damage on the right side of the brain experience great difficulty putting information together…

    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.…

    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.…

    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.…

    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).…

    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.…

    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…
