how does alzheimer's affects the normal course of human develop

by Maxine Dooley 4 min read

As it progresses, Alzheimer's destroys nerve cells within the brain and the connections between them, leaving behind clumps of proteins called plaques and twisted fibers in brain cells called tangles. Over time, this destruction erodes the most vital abilities of human nature: language, learning, memory and reason.

What are the physical limitations of Alzheimer's?

In the late stages of Alzheimer’s disease, physical ability is significantly compromised . Walking and range of motion are severely limited. Most people in this stage of dementia need to be fed by someone else and some develop difficulty with swallowing and choking. 1  Contractures, where a leg, arm or hand is bent too far and is difficult to straighten out, can develop because the person doesn’t use the muscle enough. 2  Eventually, loved ones are faced with end-of-life decisions .

What is the most common form of dementia in older people?

Alzheimer’s disease (AD) is the most prevalent form of dementia in persons older than 65 years 1. Cognitive impairment, mainly related to memory deficits, is the most common manifestation of this disease 2. Available neuroimaging evidence suggests that the neuropathological alterations underlying AD probably begin much earlier than the appearance of clinical symptoms and years before clinical diagnosis 3. From these results, it appeared that the pharmacological management was finally implemented in patients with a largely advanced neurodegenerative process, making it difficult to fight against pathological progression. In this context, the concept of disease-modifying therapies is emerging and the search for early biomarkers of these alterations is currently a hot topic of research 4.

Overview

  • Alzheimer's disease is a progressive neurologic disorder that causes the brain to shrink (atrophy) and brain cells to die. Alzheimer's disease is the most common cause of dementia — a continuous decline in thinking, behavioral and social skills that affects a person's ability to function independently. Approximately 5.8 million people in the United States age 65 and older li…

Symptoms

  • Memory loss is the key symptom of Alzheimer's disease. Early signs include difficulty remembering recent events or conversations. As the disease progresses, memory impairments worsen and other symptoms develop. At first, a person with Alzheimer's disease may be aware of having difficulty remembering things and organizing thoughts. A family member or friend may b…

Causes

  • The exact causes of Alzheimer's disease aren't fully understood. But at a basic level, brain proteins fail to function normally, which disrupts the work of brain cells (neurons) and triggers a series of toxic events. Neurons are damaged, lose connections to each other and eventually die. Scientists believe that for most people, Alzheimer's disease is caused by a combination of genet…

Risk Factors

  • Age
    Increasing age is the greatest known risk factor for Alzheimer's disease. Alzheimer's is not a part of normal aging, but as you grow older the likelihood of developing Alzheimer's disease increases. One study, for example, found that annually there were four new diagnoses per 1,000 people age…
  • Family history and genetics
    Your risk of developing Alzheimer's is somewhat higher if a first-degree relative — your parent or sibling — has the disease. Most genetic mechanisms of Alzheimer's among families remain largely unexplained, and the genetic factors are likely complex. One better understood genetic fa…

Complications

  • Memory and language loss, impaired judgment and other cognitive changes caused by Alzheimer's can complicate treatment for other health conditions. A person with Alzheimer's disease may not be able to: 1. Communicate that he or she is experiencing pain 2. Explain symptoms of another illness 3. Follow a prescribed treatment plan 4. Explain medication side ef…

Prevention

  • Alzheimer's disease is not a preventable condition. However, a number of lifestyle risk factors for Alzheimer's can be modified. Evidence suggests that changes in diet, exercise and habits — steps to reduce the risk of cardiovascular disease — may also lower your risk of developing Alzheimer's disease and other disorders that cause dementia. Heart-healthy lifestyle choices that may reduc…
