Im new to the alzheimers world since last sept. I've read books on the disease but am wondering if there is a general length of time for the stages beyond the first stage. My mom is, i believe, in stage 3 (maybe 4) ...is 86 and alone, and i am the only child who can provide support/care for her. Im wondering how fast is the progression or is it unique to each individual? Also, i read about the disruptive sleep patterns with those who have the disease and wonder what causes that? Mom hasnt started that yet, but im curious as to what causes it?
If she has a history of heart disease or stroke or heart failure, vascular dementia is likely. If she has a long history of alcohol use and liver problems, the MD will be looking for ARD with a vitamin B1 depletion that can be treated. So get the tests done and develop a treatment plan to buy time.
How much time varies greatly from one person to the next.
