My mom is being treated for dementia. She's been prescribed Aricept and Memantine. I live with her and I first noticed something was off late winter of 2018. At the time she had recently started taking Lisinopril and Metoprolol for high blood pressure. The first thing I noticed is she has trouble keeping track of the passage of time. She'll take a nap and wake up and think it's the next day. This isn't your usual what day is it type things. She will start her morning routine even if morning isn't for 12 more hours. This doesn't happen all the time but it doesn't happen enough. The second thing is hard to describe. She recognizes all of us but she also thinks there's younger versions of us. This is especially true with the two youngest children. She refered to my younger sister as "that woman who was here". She called her by her correct name. She knew who her husband was and her grandchild but the woman was not he daughter in her mind. The third thing is she's having trouble with speaking and language. She has trouble finding the right word and she mumbles. Her memory is unaffected. If she has anything planned for the near future whether it's an appointment or a social engagement, she remembers it. She doesn't misplace things and she's never gotten lost while driving. She keeps track of her own finances. After being on Aricept and Memantine for six months, there have been no changes one way or another. It's just the problem with time distortion, recognizing her children as they are today and not 20 years ago, and the speech problem.
