Clinics serving Alzheimer’s patients are working out the details of who will get treated with the new drug Leqembi. It won’t be for everyone with memory-loss symptoms.

The FDA has approved Leqembi, the first disease-modifying treatment for early-stage Alzheimer’s and a precursor condition, mild cognitive impairment. Medicare has said it will pay for the therapy. Medical centers across the country are scrambling to finalize policies and procedures for providing the medication to patients, possibly by summer’s end or early autumn.

Will demand for Leqembi , a monoclonal antibody that requires infusions every two weeks, be robust or restrained? How many older adults in their 70s and 80s will be able and willing to travel to medical centers for infusions twice a month and have regular MRI scans and physician visits to monitor for potential side effects such as brain bleeds or swelling?

These questions aren’t surprising, given that these dementia treatments are opening uncharted territory. Here’s some of what people should know:Leqembi is very effective at removing amyloid plaques from people’s brains. But it doesn’t reverse cognitive decline or prevent future deterioration., Eisai, the company that makes Leqembi, said clinical trials showed a 27% slower rate of decline for people taking the drug.

In slightly more than 1 in 4 cases, there were also infusion-related side effects — chills, aches, nausea, vomiting, a spike or drop in blood pressure, and more. He has about 20 patients ready to start treatment once Washington University starts offering Leqembi, perhaps by early autumn. Delivering this therapy “is going to be challenging, and I think we need to err on the side of caution,” he said.
