Hello, my mom is 70 years old and she was diagnosed with early dementia this year, she is taking Donepezil and Namenda. She was also diagnosed with Aortic Stenosis Low-Flow a few years ago. She is stable so far. 5 day ago she was complaining for 2 days about cramps, then they stopped, now she is saying that she feels her lower left leg is tingling. I just measured her blood pressure and it was 93/56 and her heart rate was 56bpm. She looks normal, but I just wonder if I should be concerned? Thank you, Dalila
