Your options

  • Treat Alzheimer's disease with medicines for as long as they are helpful.
  • Don't take medicines. Try other ways to improve thinking and memory and to reduce confusion.

Key points to remember

  • Medicines can't cure Alzheimer's disease, but they can slow it down for a while and make it easier to live with. They may relieve symptoms such as having trouble thinking and remembering things.
  • Medicines may not work for everyone. Even if they do work, they may not make a big difference in how you think and remember.
  • Medicines may cost a lot. You can try taking them for a while to see if they help and if that help is worth the cost to you.
  • These medicines have side effects, but many people are able to take them without problems. Side effects can include nausea, diarrhea, vomiting, belly pain, weight loss, and lack of hunger.
  • Some people with Alzheimer's disease are able to keep up their daily activities for many years, even if they do them at a reduced level or in different ways. If you decide not to take medicine, you can help yourself by scaling back on activities to match your abilities. You can also try scheduling activities during the times of day when you can best handle them.
FAQs

What is Alzheimer's disease?

Alzheimer's disease damages the brain. It causes a steady loss of memory and affects how well you can speak, think, and do your daily activities.

Alzheimer's disease gets worse over time, but how quickly this happens varies. Some people lose their ability to do daily activities early on. Others may do fairly well until much later in the disease. As the disease gets worse, you may:

  • Have trouble making decisions.
  • Be confused about what time and day it is.
  • Get lost in places you know well.
  • Have trouble learning and remembering new information.
  • Have trouble finding the right words to say what you want to say.
  • Have more trouble doing daily tasks like cooking a meal or paying bills.

What medicines are used to treat Alzheimer's disease?

Medicines can't cure Alzheimer's disease. But they can slow down the way it affects your brain and make the disease easier to live with.

  • Cholinesterase inhibitors, such as donepezil (Aricept), galantamine (Razadyne), and rivastigmine (Exelon) are the most commonly used medicines for Alzheimer's. They can boost memory and the ability to do daily activities. They can be used in all stages of the disease.
  • Memantine (Namenda) can relieve symptoms of memory loss, confusion, and thinking problems. It may help you in the middle and late stages of the disease, when your symptoms are severe. You may take this medicine alone or with cholinesterase inhibitors.

Other medicines may be used to help with anxiety, agitation, anger, or other symptoms like these.

Medicines may not work for everyone. Even if they do work, they may not make a big difference in how you think and remember. Over time, as your disease gets worse, medicines will stop working. The long-term effects of these medicines are not known.

What are the side effects of these medicines?

Most people are able to take these medicines without problems. Most side effects go away within a few weeks after you start taking the medicines.

The most common side effects of cholinesterase inhibitors are:

  • Nausea (feeling sick to your stomach).
  • Diarrhea.
  • Vomiting.
  • Upset stomach (indigestion).
  • Lack of hunger.
  • Weight loss.

Other problems are less common. You may feel very tired, have trouble sleeping, or have muscle cramps.

Common side effects of memantine are:

  • Dizziness.
  • Confusion.
  • Headache.
  • Trouble moving your bowels (constipation).

It's important to have regular visits with your doctor while you are taking these medicines. As the disease gets worse and symptoms change, your medicines or doses may change too.

If you are caring for someone who has Alzheimer's disease, watch for problems or side effects from medicines.

What can you do to help yourself without taking medicines?

If you have been diagnosed with Alzheimer's disease, you may feel angry, frightened, depressed, and worried about the future. Even though the disease gets worse over time, some people are able to keep up their daily activities for many years, even if they do them at a reduced level or in different ways.

Try some of these ways to cope, with or without medicines:

  • Scale back on activities to match your abilities. A task may take longer than it used to, but if you want to keep doing it, you should try. Make changes as needed. For example, if you no longer feel comfortable cooking, think about other things you can do, such as shopping and meal planning or setting the table. Or try using simpler recipes.
  • Schedule activities and tasks for the times of day when you're best able to handle them. It may help to have a routine that doesn't change much from day to day.
  • You or your caregiver can help avoid confusion at home by labeling often-used rooms and objects.
  • Before you go out alone, write down where you are going, how to get there, and how to get back home. Do this even if it's a place you have gone many times before. Take someone else along when you can.

Talking with people who know about Alzheimer's can help by teaching you about the disease and how to cope. Contact Alzheimer's organizations, look for community services, and attend support groups to learn as much as you can.

Why might your doctor recommend medicines?

Your doctor may recommend that you take medicines for Alzheimer's if:

  • Medicines will make it easier for you to do daily activities.
  • Medicines will reduce your symptoms and make it easier for others to take care of you.

Personal stories about taking medicines for Alzheimer's disease

These stories are based on information gathered from health professionals and consumers. They may be helpful as you make important health decisions.

As long as I'm doing all right, I would like to stay off of medicines. Some days it's really hard, because I get confused and even frightened. But I don't tolerate medicines that upset my stomach very well, and I'd like to stay feeling as well as I can until my disease progresses. My wife knows to put me on medicines if I become violent or if my behaviors become burdensome to her.

Jed, age 62

I was just diagnosed as being in the early stages of Alzheimer's disease. I'd like to remain as mentally clear as I possibly can for as long as I can. I'm going to try taking a cholinesterase inhibitor called Aricept, because it may help delay the this condition for a few more months. Even though that's not a long time, every day is precious to me.

MaryAnne, age 74

My wife, Sally, left instructions that she would like to be put on medicines if her personality changes and memory loss become a burden for me. Her memory loss and thinking problems have become severe, so her doctor has prescribed a new type of medicine called memantine that might reduce these symptoms. Even though no medicine will prevent the disease from progressing, I want to keep my Sally with me for as long as I can.

Joel, age 81

Fred, who is 77, is in the later stages of Alzheimer's disease. He was taking cholinesterase inhibitors and then memantine for several years with good results. But his body is no longer responding to the medicines. He is incontinent, and the medicines give him diarrhea. My sons and I have decided it's time to take Fred off the medicines and let the disease run its course.

Harrietta, age 73
