My mother recently had a very negative reaction to a medication (paranoia, delusions, agitation, etc.) and was hospitalized overnight. That seemed to totally tip her over the edge into dementia, which in hindsight I realize has been happening for some time. She is better now but is hearing music, noises in her head, which she says is "driving her crazy." It might well be caused by her medications (she recently started a very low dosage of Seroquel....and she takes a lot of meds), but I was wondering whether or not this could be a part of the dementia?
