Alzheimers disease EssayAlzheimers disease is a neurological disorder in which the death of brain cells causes memory departure and cognitive decline. A neurodegenerative type of dementia, the disease starts mild and gets progressively worse. Alzheimers is the most common form of dementia, a general term for memory loss and otherwise intellectual abilities serious enough to interfere with daily life. Alzheimers disease accounts for 60 to 80 percent of dementia cases. Alzheimers is not a normal part of aging, although the greatest known risk factor is increasing age, and the majority of people with Alzheimers are 65 and older. But Alzheimers is not just a disease of old age. Up to 5 percent of people with the disease have early onset Alzheimers ( similarly known as younger-onset), which often appears when soul is in their 40s or 50s. Alzheimers worsens over time. Alzheimers is a progressive disease, where dementia symptoms gradually worsen over a number of years.In its early stages, memory loss is mild, but with late-stage Alzheimers, individuals lose the ability to ship on a conversation and respond to their environment. Alzheimers is the sixth leading cause of death in the United States. Those with Alzheimers live an average of eight years subsequently their symptoms become noticeable to others, but survival can range from four to 20 years, depending on age and other health conditions. People with Alzheimer disease to a fault develop deposits of stuff (protein and fiber) that prevent the cells from working properly. When this happens, the cells cant send the right signals to other parts of the brain. Over time, brain cells affected by Alzheimer disease also begin to shrink and die. Lots of research is being done to find out more about the causes of Alzheimer disease.There is no one reason wherefore people get Alzheimer disease. Older people are more likely to get it, and the risk gets greater the older the person gets. For instance, the risk is hi gher for someone who is 85 than it is for someone who is 65. And women are more likely to get it than men. Researchers also think genes handed down from family members can make a person more likely to get Alzheimer disease. But that doesnt mean everyone related to someone who has it will get the disease. Other factors, combined with genes, may make itmore likely that someone will get the disease. Some of them are high blood pressure, high cholesterol, Down syndrome, or having a head injury. Citation Pagewww.medicalnewstoday.comwww.alz.org
