My sister, 66 years old, was admitted into hospital 2 months ago with confusion ….a teaching hospital….many many tests, MRI, cat scans, blood work double done…all normal ….…now, she is in a nursing rehab hospital, in a wheel chair, on pureed foods only, mostly in a very confused state…she did have the gait for several months prior to this…Dr is now treating her for parkinsons related dementia she is taking Aricept also, sigmate , the Sigmat began last week ….she shakes…It is horrible to witness this quick decline…she mostly is not there , but does have some moments of lucidity…I do know that Parkissons, Lewey body, Altizierrs, and dementia is mostly a guess for Drs? Any new amazing treatments?
