Hi:  From my reading WKS is often misdiagnosed. Your father should also see a neurologist.  The major difference is that Alzhiemers is a progressive disease and if you father is no longer drinking WKS is not.  So with my mother they did neuropsychological testing.  The first one about 9 months in and the second one a year later.  The findings were consistant with WKS because there were no major changes in the results. While it doesn't rule out Alzhiemers it does indicate WKS.  That said, the treatment for her is essentially the same as if she had Alzhiemers, she is taking Exelon and Namenda and those drugs have really helped.  The key is whether your father is still drinking.   Good Luck, Kathy
