I am told by the doctor - autopsy is the only way to know for sure which is awful. My mother who is only 73 has lost 40 pounds in less than a year. She has always been "a little flaky" acting and overly talkative. However, in this past year she has developed an inability to walk (she shuffles) she has to hang on to me just to get across the room. She is very fuddled and confused and has extreme difficulty expressing herself. She went from talking to much to hardly talking at all and when she does...it is like ahhh.....ahhhh....stammering. She transposes numbers (like a dyslexic person does) I have to repeat things for her to understand. She has always been a very independent woman and wintered in Florida for the past 13 years. She sold everything and moved back here in March. due to her failing health When she got off the plane I almost died. She had aged 20 years in 8 months! Eight months ago she looked and acted in her 60's. Now she looks and acts like she aged 20 years in less than a year. I figured she had a stroke or mini-strokes as well as cancer the way she went downhill so fast. She has had X-rays, CT scans of the body and brain, she has had an MRI of the brain, not to mention dozens of blood tests. No cancer. She has been to a psychiatrist to rule out a mental illness. She has had an endoscopy and colonoscopy to rule out cancer. Nothing has showed up. So the ruling according to the doctor is "dementia". I just can't believe this rapid progression of this disease. Is this normal? My poor mother has been poked and prodded since April 6th. Not to mention we have been to one doctor's appt. or procedure at least once or twice a week since April. It is exhausting for both me and for her. I am not sure if I should accept this diagnosis or if there is something else I should be looking into. (I am an only child by the way - no other support here).....I just want to make sure I am doing the right thing. I am very scared..........HELP!
