Symptoms And Stages Of Alzheimer's Disease

Alzheimer's is a disease that developers very slowly over a number of years. Some of these changes occur in the brain long before any noticeable symptoms of Alzheimer's present. Alzheimer's stages have been identified or classed using documentation of patients, to analyze and discover patterns that occur frequently in those that suffer from Alzheimer's disease.

Alzheimer's is caused by damage or degeneration that occurs to nerve cells. Typically, these nerve cells are associated with memory and learning. These symptoms indicate only the beginning or early stage of Alzheimer's disease. The degeneration slowly spreads to other cells that control other aspects of a person's mental functioning, such as behaviour, judgement and thinking. With behaviour impairment, cells that control and coordinate movement are eventually damaged too. People diagnosed with Alzheimer's live for an average of 8 years after diagnosis, but because of the fact that the stages of impairment are something of a guideline and are not definitive in a way that one would expect some thing to pass completely from one stage to the next, and the fact that the symptoms will vary from person to person, some sufferers can live for anything from 3 to 20 years after diagnosis.
