alzheimer


            
             Alzheimer's disease is a slowly progressive, degenerative brain disorder that results in abnormal brain function and death. Dr. Alois Alzheimer described the disease in the neurological autopsy on the brain of a 56-year-old woman who died several years after a progressive mental deterioration marked by increasing confusion and memory loss. He noticed an odd disorganization of the nerve cells in her cerebral cortex. The cells were bunched up like a rope tied in knots. He named the strange nerve bundles neurofibrillary tangles. He also noted an unexpected accumulation of cellular debris around the affected nerves. .
             Alzheimer's disease is a disorder marked by a gradual decline in brain function that gets worse with time. It was assumed that this change was a normal part of aging that was once called senility. The condition can develop as young as 40, but the disease is most common in people over the age of 65. Alzheimer's disease is not a normal part of the aging process. While the physical changes in the brain are very similar among different people, the behavioral and psychological symptoms that result are complex and may differ from person to person. These symptoms lead to a form of dementia.
             As Alzheimer's disease progresses, these losses will result in total dependency for the simplest activities. Alzheimer's disease usually consists of three stages. The first is the onset stage. There may be some minimum memory loss, particularly of recent events. These changes may last for a period of up to five years. The second stage, the progressive stage, contains the same symptoms, but is now more obvious. Memory losses become even more pronounced. They may also begin to experience loss of self-care skills, and severe changes in personality may begin to become obvious. These changes may last up to twelve years. In the third stage, the terminal stage, the people affected now experience substantial dysfunction.
