A cognitive disorder is a psychological disorder that affects the cognitive abilities such as memory, problem solving, and perception. (Cherry) Some anxiety disorders, mood disorders, and psychotic disorders are classified as cognitive disorders. (Cherry) Other types of cognitive disorders are Alzheimer’s disease, delirium, dementia, and last amnesia that. People develop these disorders over time as they grow.
The first disorder is Alzheimer’s. Alzheimer is a type of dementia that causes problems with memory, thinking and behavior. (Alzheimer's Association ) The symptoms for Alzheimer’s usually develop slowly and gets worse over time. Its early stages are memory a mild. With later stages, the individuals lose the ability to carry on a conversation and respond to their environment. Alzheimer’s becomes severe enough to interfere with daily tasks. Alzheimer’s is the most common form of dementia. Alzheimer’s is the sixth leading cause of death in the Untied States.
Second is delirium. Delirium is a sudden severe confusion and rapid changes in brain function that occurs with physical or mental illness. (Delirium: MedlinePlus Medical Encyclopedia, 2013) This is most often caused by physical or mental illness and is usually temporary and reversible. Delirium involves a quick change between mental states for example, from lethargy (also known as fatigue, is a feeling of weariness, tiredness, or lack of energy), to agitation (an unpleasant state of extreme arousal (stirred up or excited), increased tension, and irritability), and back to lethargy.

  • The Role of Genetics In Alzheimer’s Disease

    3344 Words  | 7 Pages

    Memory plays a significant role in the everyday lives of people of all ages. It allows them to recall information and remember skills that were learned in the past. Memory also organizes past information to help people make current and future decisions. However, imagine forgetting the names of close family members or not having the ability to find your keys every time you want to leave the house. These are some of the struggles that people with Alzheimer’s disease face daily. Alzheimer’s disease was first identified by German neurologist Alois Alzheimer in 1906, and was discovered to have an overpowering effect on explicit memory loss (Gruetzner, 1988). There are two types of Alzheimer’s disease – early onset and late onset. Early onset occurs in patients who are diagnosed before the age of 65 whereas late onset occurs in patients who are diagnosed after the age of 65. In the early stages of Alzheimer’s disease, short-term memory is often lost. As Alzheimer’s disease progresses, problems with long-term memory begin to develop, in addition to short-term memory impairments. Although a lot is known about the symptoms of Alzheimer’s disease, the cause has not been conclusively identified. However, as research continues, new theories about the cause of Alzheimer’s disease are being proposed. This has led to a controversy over whether Alzheimer’s disease is caused by genetics or environmental influences (Gruetzner, 1988).

    Nolan attempts to elucidate not only the various complexities involving Lenny’s self-discovery but also the value of life itself through his theatric display of anterograde amnesia. Anterograde amnesia is a devastating form of memory loss in which the individual loses the ability to create new long-term memories (compared to retrograde amnesia which affects memory from the onset of the pathology backward) (Emilien 185). This disorder can arise from damage to parts of the brain such as the hippocampus, diencephalon and other structures within the prefrontal cortex (Sano 1). For a long time, neurologists struggled to determine the most fiscally and scientifically efficient way to study amnesia. Electrical stimulation of patients...

    Alzheimer’s disease is a form of dementia which is a brain disorder that impairs mental functioning. Dementia attacks the part of the brain which controls memory, language, and thought. It makes everyday tasks like remembering to brushing your teeth, or to pay your bills next to impossible to do, which is why so many people who are diagnosed with this disease are in complete care. This disease has different phases, the first being slight forgetfulness and then the persons emotions may heighten as well as language impairment, violent outbursts, loss of bladder control and from there it keeps getting worse until complete dysfunction of the brain occurs and eventually death, which most of the time is the result of infection.

    Alzheimer’s disease is a brain disorder that results in irreversible deterioration of memory and cognitive abilities (“Alzheimer Disease”). In 2016, about 48 million individuals were living with dementia worldwide (“Alzheimer Disease”). An article in the Encyclopedia Britannica states, “Alzheimer’s disease is the most common form of dementia, being responsible for about two thirds of the cases of dementia in patients over 60 years of age. Women are affected twice as often as men” (Robbins). Another article in the Encyclopedia Britannica states, “There are three recognized stages of Alzheimer’s disease: preclinical, mild cognitive impairment (MCI), and Alzheimer’s dementia” (“Alzheimer’s Dementia”).

  • Memory Inc. Summary

    This chapter “Memory Inc.” was unfortunately a very different type of chapter for me. The concept of this chapter was to test our memory. It had different views of scientists arguing different things about the effect of memory. Lauren Slater mentioned this, “Dr. Scoville had an idea. He suspected Henry’s seizures might be kindling deep in the wetlands of the temporal lobes, a little spark quickly catching flame in a supposedly toss-away of the brain: the hippocampus” (205). Can we really cure and help something by offering a surgery or doubling the dosage of narcotics? It was said that our past can leave us in an instance, memory problems will always be there, as a person we just hold onto what we want to.

    The brain, which weighs only three pounds and is made up of eighty percent water, is the key organ of our nervous system. It is divided into three different parts: the Cerebrum, the Cerebellum, and the Medulla Oblongata. The “gray matter” of the brain is about one-eighth inch thick and it gives the brain its gray color. Inside the brain is the cortex, which is made up of billions of neurons. These neurons extend into the cerebral hemisphere and it controls all mental activity. In this report I will be discussing different disorders of the brain and how they affect the every day life of people who may have these disorders. (The Volume Library 900)

    While this overwhelming experience could have been a reason to avoid brain-related fields, I am instead drawn to understanding the cause. As an undergraduate in college, I chose to study cognitive neuroscience and work in research labs studying cognitive impairments. In my graduate study, I plan to study the human memory system and its many components. In particular, I will study the hippocampus and its role in different cognitive systems, including but not limited to memory, learning, attention and perception, and social interaction, using a variety of neuroimaging methods. Beyond academia, I hope to continue work in science outreach, including school-based and online, to further educate the public about neuroscience.

  • Essay On Delirium

    Lena, addressing the underlying cause of the delirium is the most critical component to treating the individuals’ condition. Delirium develops from metabolic disturbances, infections, inadequate sleep hygiene, anatomic disturbances, and substance/alcohol withdrawal (Townsend & Morgan, 2017). These underlying causes must be addressed with additional interventions to successfully eliminate the delirium. For example, a non-pharmacological intervention for delirium in a study suggests the application of ear plugs and dimming the lights to improve the frequency of sleep disturbances associated with the conditions’ etiology (Oh, Fong, & Hshieh, 2017). Improving the underlying cause of the condition is helpful for healthcare professionals to treat delirium and these components can be addressed with many non-pharmacological interventions. Research has shown that these non-pharmacological interventions have been highly suggested rather than pharmacological
