My Mom is almost 82 and recently diagnosed with Alzheimer’s. She is also a diabetic and takes medication for her heart as well. Lately she has been having spells where she is shivering, says she feels like there is cold running through her body. It puts her to bed most days and she covers up and gets on the heating pad. We think her medications are causing this. She sleeps well at night, feels good in the morning, then usually around 2:30-3:00 she has these spells. Today, she was having a great day until about 6:00 pm. We have recently seen her primary and diabetes doctors and all vitals and blood sugar was fine.
