Excellent article. I suggest you read it. Do remember, however, that dementia is a symptom of disease, and not all dementia is caused by Alzheimer's Disease.
"The National Alzheimer’s Association has developed a very useful tool, or “staging system,” to use as a frame of reference when coping with Alzheimer’s disease. "
My father had dementia due to a brain tumour. There are many causes. As Carol says, many do not follow these stages. What is important is early diagnosis, recognition of the disease and treatment, as well as preparing for the final stages.
