My Mom is 87 years old and has mild to moderate dementia. She was fine except for her short term regular memory stuff. She got a UTI infection & started have delusions that her skin was turning black and gray & peeling off & burning & she had a rare disease and was going to die. The facility gave her antibiotics & it shows the UTI infection is gone but she is still have delusions that her skin in peeling off & she is picking at her face. She takes rivastigmine 1.5mg a day,, valsartan f/c 160mg, Levothyroxine 88mcg, vitamin D2, Cerovite sr tablet. I wondered if any of these medications could cause delusions? or it could be the progression of the dementia?
