I am wondering what side effects from taking Aricept or Namenda are most common. Are these the most often prescribed medications for dementia or alzheimer's? My mom has been very resistant to getting a diagnosis and having to take prescription medications. One of her major concerns with medication is it's side effects. I think she is also in a bit of denial. So I am just hoping someone can share their experience with these medications and their side effects so I can try to ease her into the idea of getting a diagnosis and starting medications. Thank you in advance.
