Do I stop treatment if my Centeloid score goes down??
Hi helpful friends,
I'm 66, was diagnosed a year ago and have had monthly Kisunla injections for 7 months. When I was diagnosed, my Centeloid score was 95.5, but a PET scan yesterday showed a Centeloid of 6.7!
Should I stop treatment? That scares me - what if the Amyloid plaques return? Liqembi has maintenance doses, but I don't think Kisunla does.
I think my neurologist will try to convince me to stop, but I am scared. . .

My wife is in siilar situation (finished her 7th Kisunla ) and had no side effects.
Our neurolegist suggest we do pet-san after the 12th infusion and he recommends we stop it once it gets down to normal level which is 20-24.
I am thinking to switch to Lequmbi once it gets below 20 since this also removes the floating portofills.
Can I ask how did you get your centeloid data after just 7 infusions?
I like to get the mid point data but my doctor does not recommend it even though I am willing to pay out of pocket.

I also forgot to mention that teh amoyloid will build up very slowly I am told (about 3/yr)

I was recently diagnosed with Alzheimer’s dementia and doctor put me on Donezepil pills. Is anyone here also taking this medication and what are your thoughts about it. Thanks in advance.

should I tell my family and friends about my recent diagnosis of Alzheimer’s dementia? I would like to hear from you on this subject. Thank you in advance.

Hi Aldea, yes I have been on Donepezil for about three years now. I find it quite helpful. I think it helps me feel less "brain foggy", if you know what I mean. 😊 GE

I'm also taking Donepezil once daily, and agree with GEH on this. It seems to "clear the fog". Of course, it follows that I have less confusion, and more clarity and motivation.

Yes, thanks lfaust58, I did not elaborate on what you brought up. I would have to agree. It definitely helps with the clarity, confusion and motivation. Thanks for helping to clarify. :)

I am glad that several of you are seeing the benefit of Donepezil. Like so many medications, it helps some and others don't see a benefit. I will say that my DH has been on it 14 years. His description is "my head isn't in such a deep fog."

My doctor was able to convince insurance to give me a PET after 6 infusions because I had ARIA-E (cerebral edema) and he wondered if we could just stop the infusions.

I was told 4%/year re-build up . . .

According to Eli Lilly (the drug company responsible for Kisunla), they found in the Phase 3 trial with Kisunla that the amyloid rebound rate after stopping treatment was 2.4CL per year. This information was obtained due to a unique aspect of Lilly's trial with Kisunla. At week 24 and 52 of the trial, patients received an amyloid PET scan. Those who were receiving Kisunla were blindly switched to placebo if they were found to be amyloid negative. The term "blindly" is indicating that during the trial, patients didn't know if they were receiving Kisunla or placebo.
Participants in the trial received a third amyloid PET scan at 76 weeks. For those who were switched from Kisunla to placebo due to amyloid plaque clearance at 24 weeks, Lilly reported no substantial amyloid reaccumulation from 24 weeks to 76 weeks (the average amyloid increase over this timeframe was 0.95 CL).
Using the individual patient data in the Kisunla Phase 3 trial for amyloid rebound rates after stopping treatment, Lilly developed a computer model to predict the amyloid reaccumulation rates. The simulation model estimates an average amyloid reaccumulation rate after stopping Kisunla infusions of 2.4 CL per year (as noted previously). Lilly noted that this compares favorably with the natural estimated rate of amyloid accumulation of 3 CL per year.
One Lilly researcher has commented that for the average Jane/Joe receiving Kisunla infusions, after stopping Kisunla infusions because of amyloid plaque clearance, the low estimates of amyloid reaccumulation rates are such that the average person would not need to restart Kisunla infusions in their lifetime. But if someone started Kisunla infusions when they were in the early 60's, and their personal amyloid reaccumulation rate was a bit higher than normal, one might expect that person might have to have a second round of Kisunla infusions later in life.0 -
I love reading commements from you. They are so full of facts, specific details and lots and lots and lots of detailed specific information. I always learn something from you when you contribute to any conversation. Much thanks always for your contributions.

Thanks for this info, which is aligned with my neurologist's comment that it's a 4% re-increase per year.
Is there anybody here who moved from Kisunlia to Liqembi after clearing amyloid in order to benefit from Liqembi's ability to clear proto-fibbrils? Apparently Liqembi maintenance dose is going to move to self-infusion (or from a pharmacy) in August of this year.

I'm part of a Facebook support group for those on Leqembi or Kisunla. Some individuals on Kisunla have done as you suggested: after amyloid clearance with Kisunla, they switch to Leqembi for maintenance dosing. Today, there are two delivery options for Leqembi maintenance dosing. I'm receiving Leqembi maintenance dosing via infusions every 4 weeks. The other option currently available is a weekly injection with IQLIK (their term for the device that delivers a subcutaneous injection of Leqembi into the fatty tissue below your skin). As you note, the concept is that Leqembi is dual-acting, removing both amyloid plaque and amyloid protofibrils (whereas Kisunla is single-acting, removing only amyloid plaque). Amyloid protofibrils are thought to also cause damage to neurons, hence the rationale for Leqembi maintenance dosing (to remove the continually forming amyloid protofibrils). I had an option to switch from infusions to IQLIK for maintenance dosing. With my medical insurance (Medicare + Blue Cross Blue Shield supplemental), infusion maintenance dosing have zero co-pay. I received a quote from Blue Cross Blue Shield for a co-pay of $711.95 for a 28-day supply of IQLIK. I'm cheap, so I elected to wtick with IQLIK for now. It is my understanding that Eisa (the company that developed Leqembi & IQLIK) got Medicare approval for IQLIK late in 2025, such that many (most?) insurance companies have large co-pays for IQLIK in 2026. I'm hoping that 2027 will be a 'normal' year, with Medicare / Blue Cross covering IQLIK just like they cover the infusions.
The August date you referenced is the anticipated FDA action date on a request by Eisai for approval of IQLIK for initial dosing of Leqembi. This means that very shortly, newly-diagnosed patients may have the option of starting Leqembi using IQLIK (i.e. zero infusions!). I presume that patients currently receiving infusions during the initial treatment period with Leqembi may also consider switching from infusions to IQLIK. However, they may fall into the same situation that I did, with higher costs for the IQLIK compared to the infusion.
For those really into the details, the IQLIK for maintenance dosing uses a smaller amount of the active drug, compared with IQLIK for initial dosing.3 -
Thanks for this very helpful information. I'd like to join the Facebook group, but I'm finding lots of FB groups - can you tell me the exact name or URL (link to that group)?

The Facebook group is called "Leqembi and Kisunla Support Group". It is a private group, you have to request membership. The two questions are highly complex: click the appropriate box indicating why you wish to join, and check a box indicating that you will abide by the group rules. You would be surprised at how many people fail to address both questions (resulting in denial of their request to join the group).
At one time I joined a public support group. But I found that many people posed non-scientific mumbo-jumbo (i.e. 'I saw an article indicating people should take **** to cure their AD!!!'). I grew weary of such nonsence, and joined the private group, which I found has very sane people who actually are on either of the two drugs (or their care partners).1 -
Thank you - I just joined the group - no problem with the questions :-)

Hi. My name is Dana 66 and im also new to this group.
I have been taking Memantine and Donepezel.
The Donepezel is great....no problems. But I just started taking Memantine twice a day.
I have been taking 1 a day and all was fine. But when I took the second that I was prescribed it made me sooo tired. I was working and it was tuff.
Will I get used to it if I keep taking it?

Hi Dana,
I am taking Memantine ER 28 MG. I take mine in the morning with no ill affects however, my prescription tag does indicate it may cause dizziness. The tag does not indicate it must be taken in the AM specifically, but rather, only "one a day". Maybe your Dr. would be ok with you taking it at night before sleep so it does not affect as much. My MD also gave me a script for Glalantamine ER , another symptom helping drug which I find very helpful. Maybe your Dr. would want to prescribe this for you also. It also also does not appear to make me sleepy.

I’ve just completed my 7th infusion of Kisunla, I will have my 8th before seeing my Neurologist in August. Hopefully by then I will get updated information on its effectiveness. Chose Kisunla over Liqumbe after speaking with him and researching. Seems plaque can return but it seems to take 20 years, I feel I can live with that as it puts me beyond the life span of my parents and their siblings.

most people are put on Donepezil when first diagnosed to support memory.0

i was diagnosed with MCI and with biomarkers for AD about 1 1/2 years ago and have been taking donepezil for the last several months. It's not a cure, nor does it slow progression. But it can be helpful with symptoms. Is it doing me any good? The only thing I know is that neuro testing a couple of months ago showed to decline from the a year previous to that. In the meantime, I haven't experienced any significant side effects. So I keep taking it.

I think you should share your diagnosis when you feel comfortable enough.

I would have to agree... i personally would only give the basic of info and allow them to take that in and ask questions if they twant. They may not want to at first, but may come back to you later with some.

Yes, i've been taking Donezepil for close to a year. Is it helping? That's hard to say, because of course I don't know how I would be functioning if I wasn't taking this med. What I can say is that I don't think I'm experiencing any deterioration. And, the side effects of Donezepil (mainly stomach upsets) are quite tolerable. So I keep taking them. I've always exercised (physically and mentally) and eaten fairly well. That too helps.

My Hubby is on Donezepil and it has reduced his anxiety and stress. He has not had the GI side effects. It's a med that helps symptoms but not any affect on progression of the disease.

I was also recently diagnosed and started Donezepil - I’m have taken for only about 3 weeks and am still shell shocked with the diagnosis.
