Docs put our Mom on Aricept for dementia. The drug had just the opposite desired effect. She was lost. Mumbling, stumbling, walking into walls. My sister and I made the command decision to stop giving her the medication and Mom recovered nicely. There was another “dementia” med she was prescribed that had the same effect...can’t remember the name (didn’t look familiar in your article). Stopped that also. The only “prescription” that ultimately worked was the locked door in the “memory unit” at a local elder care center.
I hated the process of visiting Mom behind those locked doors. Passing in or out you always had a group of inmates trying to get out. Pitiful souls. Always shuffling up and down the hall until they wore themselves out. Like fish constantly circling a huge aquarium in an endless circle.
