We had a long day on Friday, doctor's appointment about 4 hours from home and she was extremely tired but refused to go to sleep in the car on the way home. She was extremely confused and mumbling her words, and wasn't making much sense. We attributed it to her being tired and hoped that with some rest she would go to back to "normal" (I hate that word when it comes to PD patients). My sister is in town and she stayed with Mom over the weekend and said while she was a bit better, she is still confused on how long she has lived in her house, talked about our father in the present tense (he passed away in August of last year), the fact that my daughter graduated from high school in 1965 (um no), etc. She is also wheezing which is better this morning and the home health nurse is coming by today to check on her. If she isn't better this afternoon, we are going to call doctor to rule out a UTI or other medical issues.
