My mom is 66, has been having memory and cognitive problems for 5 years, and was forced to retire from teaching 4 years ago, but was officially diagnosed with vascular dementia and alzheimer's last year. Looking at the 7 stages of alzheimer's, she is functioning right now at the end of stage 5. It has seemed to progress pretty rapidly. Is there anyway to predict how long the last 2 stages of alzheimer's would last for her? She went through stages 3 and 4 in about three years and has gone through stage 5 in about 1 year. She has had no heart attacks, but has had one very small stroke. She has had high blood pressure and high cholestrol, and is high risk for heart attack and stroke, but is on medication.
