It would absolutely be helpful to have a little more information.
It aricept a wonder drug that is going to bring back our loved one's cognitive ability like the advertisement appear to be saying? NO. It only promises to slow the progress in some patients. If you look at the medical research on the drug you will see the normal slow downward in the control group. In the group with aricept there is a slowing of the decline in the very beginning of it's use and then it follows the same patters as the control group.
There are also side effects to be concerned about.
The best course of action is to have your loved one diagnosed by a geriatric neurologist or cognitive testing center that specializes in dementia treatment. Keep a lot of the behaviors before the med is started. When and if your loved ones gones on the med continue to keep the log. That way you will notice any changes in cognitive ability, behavior, or other side effects. The log will be invaluable to you and the doctor to make a determination if it is worth continuing.
It also matters what stage our loved one is. The earlier in the dementia process the better. It also matters what type of dementia your loved one has. Aricept is for Alzheimer but doesn't do anything for other dementias.
So it all depends on your situation.... so let us know a little more
