Experience with Donanemab and Lecanemab

Posted by spoolly @spoolly, Aug 11, 2025

My wife has been diagnosed with Alzheimer’s and her Mayo neurologist recommended treatment with either Donanemab or Lecanemab. Does anyone have any experience with either of these drugs? It seems like we have a million questions.
How do you choose between the two?
The infusion time with either one is relatively short, but sounds like your actual time is much longer. Are you generally able to get by with one day of medical each cycle?
How bad are the side effects? Are you potentially losing 18 months of relatively good time during the disease progression while you go through treatment?
There are numerous articles which question whether the benefits from the clinical trial will actually follow in actual practice. What kind of actual experience have people experienced?
I am not sure why our family and myself seem to be questioning this treatment. My wife is a three time ovarian cancer survivor. She has obviously been through quite a great deal from a medical standpoint. The medical community and specifically Mayo has saved her. If one of these treatments will help there is no question we will proceed. I am sure part of our hesitation is in our situation the treatment cannot be done at Mayo.

My wife is 70 and was recently diagnosed with Alzheimer's Disease. Her specialist has recommended Kisunla infusions and the first one is scheduled for May 13, so in about 2 weeks. Her only symptom right now is really bad short term memory. She is fine and her usual wonderful self in all other ways. We just got back from a two week trip to Portugal and had a wonderful time. So I am really torn about the infusion treatments. She seems to want to do it, and I am generally in favor of it also--as in anything that will give her more time before more serious symptoms develop. But the risks really trouble me, as well as articles (some very recent) questioning whether the infusion treatments really help. I would appreciate any and all viewpoints and experiences, positive and negative, about this. Thank you.

@paul55 Paul, sounds like we are in similar situations..the more I read about the infusion therapy the more concerns I have…my wife has a real anxiety problem now and I question if the cons of the therapy outweigh the pros. I try to keep her active socially which has a positive effect.. would appreciate your input after your wife’s first session
Thank you

@joemurphy43 PS, I just posted an answer to you, but my husband on the lequembe treatment is almost 79 years old. And the man I referenced in my answer to you, who did see an improvment was in his upper 80's.
Best, Karla

@joemurphy43 I just pulled from some of the Mayo stuff I print out, so I remember, something about, "15 Things to Know about the Two New Alzheimer's drugs by Marlene Cimons. It's an AARP magazine article Nov 6. 2024 in the health section. Goggle it and it may be helpful in trying to make a decision for your wife. Also, there are a lot of people on the lequembe infusions, so there must be more statistics out there now. Possibly your neurologist has some of that data. Best, Karla

Hello, Paul!
Similar situation with my husband at 73. First, congratulations on getting to Portugal! We signed up two years ago, but with all going on with tests last fall, I almost canceled it; however, daughter urged us to go, and it was so worth it with wonderful memories!
Now we are focusing on the Kisunla infusions, required MRIs, and communication with the neurologist. Our life seems built around those things. There are good friends and activities at church that I can engage in, but my world is a little smaller as we focus on calm and not running around. I go to a support group and am still processing after the first year of observing memory lapses and bad judgment. My husband is also taking Aricept and feels that he is much better than the humongous step down he took last year. I think it is helping to some extent, but I have taken over driving and we do any computer decisions and bill paying together. He thinks he is doing so much better that he is back to normal.
As far as the infusions, he has had two, with the only real concern an unusual-for-him headache the day after the second one. Doctor ordered an additional MRI that showed no ARIA, so we are preparing for the third infusion. Maybe ???? the infusion treatment is helping, or maybe it is the Aricept, but he definitely is better than the foggy moments we had months ago.
I am grateful that he started treatment early on, as tests have indicated Alzheimers in his future. Of course, there is no predictability. We just tried to get financial and legal things in place and put in motion some plans to relocate— in my mind sooner than later to be nearer to family, but of course we are tied into the treatments just now. As I am sure everyone on this thread knows, it’s looking for some joy to be had one day at a time, and some days are easier than others. A friend who has had experience with her husband’s disease told me to treasure the frustrating moments: for instance, I think I park the car perfectly well, but my husband gives me a detailed analysis of how I could do it better EVERY TIME we go out and tells me that we need to go to an empty parking lot to practice (that had not happened yet). I am just trying to remember to treasure that for the days that may be ahead.
God bless you as you make your way through the decisions at this time.

@mugsarella thank you so much for taking the time to share. I hope things go as well as possible for you and your husband. As of now, we are going forward with the infusion next week. Will let you know how things go. Take care.

@joemurphy43 Joe, I can only tell you that when I'm sitting at the neurologist with Eddie, my husband, other wives or husbands are in there. The women my husband is sitting with when he has his infusions, one woman was 89 years old, no issues, another was 86 years old. I know one woman, was very nervous, they ended up slowing down the infusion. You can ask the doctor about that. And when she came back, she wanted to do it on a day, the neurologist was there. you know, it's so hard to know, but our infusion center in South Florida is packed with people going in and taking them. doing. I don't mean to make this sound like a promotion for lequembe. I know it's a hard decision, but my husband was very positive over it. And the people going in, men and women, seem to feel the same way, (at least the ones I talk to all the time) Good luck. Best, Karla

Hi. Does medicare cover the cost of these drugs? If not, may I ask how much each treatment costs?

My husband was on lequembi and then kisunla and it was covered by medicare. he had a fall which caused some brain bleeding while being treated with lequembi so the neuroligist stopped the treatment. a few months later, kisunla was approved so he started that. after treatment 3, he experienced a weakness which i didnt realize was from the kisunla. we went to the er but then he was ok. after treatment 6, he experienced the same thing so we stopped the treatment. the nurse practitioner suggested another pet scan to see the results. i was shocked to learned that all of the plaque was gone. i would say that the result is that the progress of the disease has been slowed down.
