She had no recall of sharing FAcebook photos with her and when I viewed the photose with her again, she kept saying and repeating I have never seen these pictures before. Also repeating herself over and over and obsessing about things. Is this dementia?
Alz symptoms mimic many others...ie: a result of a UTI infection, fever, drug interactions, etc. My Mom had a bad reaction to pain meds and the first thing out of the doc's mouth was "alzheimers." I told him that if she had Alz, then we all do.
Also, you are also the best guage of your Mom's behavior. Keep an anecdotal record. Occasional forgetfulness is common. If she is disoriented, forgets faces and events often, or seems unduly agitated...then something else is going on. Has she had a physical recently? I would recommend one with blood and UTI testing.
