Husband diagnosed in late 2018, put on meds. He doesn't sound like the people I see mentioned in a group I finally joined. His biggest problem is vision. He exhibited strange symptoms such as moldings, tops of doors, moving upward. It's hard to understand prepositions. He can't "see" things when there's conversation about it but when he initiates it he seems to do better. He hasn't forgotten faces yet. Short term memory is worse following agitation. Is there that much variation in Alzheimer's patients?
