My 88 year old dad has Alzheimers, and like many people with elderly parents, I am his primary caregiver. It's taught me patience I didn't know I was capable of. Some days, like today, are more frustrating than others. Some days, like today, require saint-like patience. If I weren't so flippin' tired it would be easier. I've missed my mom every day for 37 years, but never more as an adult than I have the last few months taking care of dad.
My grandmother had Alzheimer's and my father in law is showing early signs. He's become angry and frustrated and won't acknowledge what's happening to him. I'm not sure how I'd react to that news so I withhold judgement but I think cognitive decline is one of my biggest fears.
