My father was diagnosed with Alzheimers 3 years ago at the age of 67. He has progressed very fast. He is exhibiting moderate to late stages of the disease. We had to place him in a nursing home Alzheimers unit 4 weeks ago. He was beginning to become more angry and would hit and shove my mother and daughter. At the end of his 3rd week he has started to severly lean to his right side. He has parkinson's. He has severe arthritis to his Left shoulder. He had his Right shoulder replaced 2 yrs ago. He recieves pain medication for shoulder and this does not seem to lessen his leaning. Of coarse he will lean to the right side when sitting too.
