Still Not Sure
Like bakeja I, too, have not had a formal diagnosis for my husband; and I'm not sure I really want one.
My dear husband is eighty-eight,. I am seventy-five. He is catheterized, and has epilepsy, a deformed spine and a recently broken hip. He is totally dependent on me for everything. His mind has been slowly overtaken by confusion, especially in the early evening, when he sits taking nonsense. He has very little memory of the past,( and by past, I mean lunch!) and has even forgotten the names of our four children.
He always had a deep dread of falling prey to Alzheimer's, or dementia; and as a creative writer, the clear functioning of his mind was essential, not only to his sense of self, but to our livelihood.
Several doctors have agreed, in private, that he has dementia - but I managed to keep this diagnosis from him. He was always pretty disorganized, and the, 'forgetful writer' was quite an acceptable persona for a long time.
He will gradually fade further away , disappearing into dementia without ever being distressed by the dreaded label.
I hope I was right - but I'll never be sure.
