Abnormal Psychology for Alzheimer Disease and Vascula-myassignmenthelp

Question: Discuss about theAbnormal Psychology for Alzheimer Disease and Vascula. Answer: Neurocognitive Disorder Due To Alzheimer's Disease In the neurocognitive disorder due to Alzheimers disease the patients cognitive domains like learning and memory are impaired. There are two types of cognitive disorders like major and minor (Solomon et al., 2014). No cerebrovascular diseases can be found in the medical history. When the disorder is major the patients everyday activities are interfered. The decline in memory is gradually progressive. Generally the age of average people to get affected by this disease is 80 and men survive up to 4.2 years and women 5.7 years (Mentalhealth.com, 2017). Agnosia and Apraxia are common in the disease. Vascular Neurocognitive Disorder This is a neurocognitive disorder due to disruptions in brains blood supply (Elementsbehavioralhealth.com, 2017). The decline of the cognitive happens in fluctuating or stepwise course and there are improved stable period in between unlike the gradual progression neurocoginitive disorder due to Alzheimers disease. Generally grows in a rapid speed after a stroke. History of other cerebrovascular diseases can be found in the medical history. This disorder can be experienced in any age, however the severity increases after the age of 65 and common survival period is 4 years(Mentalhealth.com, 2017). According to Konrth et al, the treatment of Alzheimers disease sees promises in the ICHE Cholinesterase inhibitors drugs as the enzyme proves to be effective. In this drugs quaternary beta-carboline, huperzine, lycorine and aporphyrin alkaloids are used. These chemical groups are generally used in the clinical phase of Alzheimers diseases symptomatic treatment however the researchers are considering changed course and mechanism are being considered. The A oligomers in relationship with enzyme cholinesterase are the source with increased density and subsequesnt neuron disposition. In the conventional practice of treatment Galantamine or Physostigmine alkaloids are used. During the course of Alzheimers, the researchers have been investigating some natural alkaloids in order to identify the changes. Like Triterpene which is a steroidal alkaloid and promotes inhibition of non competitive type, benzylisoquinoline and aporphyrin are isoquinolines that are non competitive and beta carboline s are non competitive (Sun, Jin lin, 2012). On the other hand Huperzine alkaloids such as lycopodium and quinolizidine alkaloids promote inhibition of competitive nature, lycorine, galantamine, physostigmine, monoterpenes and indole alkaloidsa re competitive compounds (Len , Garcia Marco-Contelles, 2013).The authors claim that among so many competitive and non competitive compounds, the huperzine is selective, potent and reversible. This was successfully applied in organophosphate poisoning, myasthenia gravis and schizophrenia. The successful trail of Huperzine resulted in improved in short term memory. However its toxic effects have to be minimized in order to make it more effective. There are other issues related to Huperzine its limited ability to overcome blood brain barrier and it is highly selective. Further detail research and trial will enhance its possibility. According to McGuinnes et al, Allele APOE ?4 expresses the apolipoprotein E subtypes action which is highly potential to effectively link between NPs and A oligomers. GSK 3beta activities can also be increased by it and this can cause tau protein like hyperphosphorylation and NFTs are formed. This protein subtype statines is capable of reducing A plaque formation. This drug is significantly effective in the treatment of Alzheimers disease because of its lipid lowering power. This specialty of Statins makes it a multi target drug. In certain cases of dementia the researchers have found evidences that this subtype reduces systematic cholesterol. The brains cholesterol level can a;lso be controlled by the Statins mechanism which results in reduced NFTs. The physicians have been using Stanits in increased number after it showed positive results in the patients. The Alzheimers patients have been experiencing lower level of dementia after using this drug for a certain period. This drug has also shown signs of crossing the brain blood barrier in more successful manner that other drugs. The usage can also improve the CNS circulation Loci. Howver there are only limited investigations has been observed dutring the course of Alzheimers which successfully makes it the most effective prevetion. Above that if it is applied for a continuous lng period to te Alzheimers patients , it might shows hepatic impairment. The Rhabdomyolysis risk can be increased as well and there are laso safety issues assoviated with the use of Statins. The researchers have conducted a meta analysis and nineteen observational studies to determine the drugs longitudinal and cross sectional actions. The cross sectional observation demonstrates that Statins are really eff ective drugs. The results have also highlighted that Statins is capable of reducing various forms of dementia among Alzheimers disease patients. Feng and Wang (2012) researchers have found that during the course of Alzheimers disease, the oxidative stress causes serious problems for the victims and increases the severity. The NFT or NP progression and increased inflammatory process are enhanced by some glicidic, protein or lipid oxidation. This generally happens prior to pathophysiological treatment. This leads the researchers focus on the antioxidants as a potential preventive element in the Alzheimers disease. They investigated the antioxidant compounds that are capable of treating the preventing the Alzheimers disease. The antioxidant compounds are likely to resist Alzheimers pathophysiological course and hold that capability of reducing the ROS or reactive oxygen species. The a-tacopherol of the vitamin E has gain much attention among the researchers as an effective anti oxidant compound capable of bringing the desired successes. Over a period of 4 years during the treatment course of Alzheimers disease this vitamin E sub stance has shown the evident of lowering the development of Alzheimers. The multiple trials have shown the result between 2.5 and 4.0 fold. However, not many investigations have been done to measure its great potential to become an adjunct of the treatment. Selegiline is another drug that has shown positive sign in the treatment of Alzheimers. the behavior and mood of the Alzhiemers patients have been improved by this drug. This result has been concluded from evaluating by 12 researchers in 8 different trials. Another meta analysis related to the use of the Selegiline has shown that there is also an improvement in the victims memory. The antioxidant qualities and capability of increasing blood circulation of Ginkgo Biloba demonstrated significant result in the treatment of Alzheimers disease. This can also resist synapses reduction and can increase the neurotrophic production related to Alzheimers neuronal apoptosis. This is the reason that the drug is capable of improving the behav ioral qualities by reducing the A induction of the Alzheimers patients. However the researchers have also found that the drug is capable of causing several side effects during the application especially when used during the anticoagulation therapy. There are other antioxidant compounds found in the antioxidants that have demonstrated potentiality in Alzheimers treatment, like Carotenoids of Vitamin C, Omega 3, Vitamin B12, resveratrol, glutathione and palmatine alkaloids.
