I have had aphasia since I had a stroke at 44. I keep a list of words I screw up => mushroom/marshmallow for example, and my kids just know to translate.

I went through an episode of confusion last year. It turns out that people over 60 are prone to them due to lack of sleep, dehydration and UTIs. So it's just one more thing to watch for. I had pneumonia and apparently was suffering from lack of sleep.

I'll keep your mother in my thoughts.
