So, heard back from the Dr at Mom's rehab and last night's MRI did reveal a small stroke, so I don't know how much, if any, of the language deficit she's going to get back. He's working on getting her fluids equalized so that her kidneys and her heart aren't in such immediate danger, but he basically said she's dying. I've suspected for a while now (5 hospitalizations in 3 months), but it was still hard to hear. He said she's got probably 6 months to a year (though a year is optimistic). Still processing.
And now I'm leaving to go see her. My brother's finally coming too. Glad to know when the actual death knell rings he'll finally step up.
