Why the Next Big Hope for Alzheimer’s Might Not Help Most Black Patients

This week the FDA is expected to approve what many scientists and doctors believe is the first drug to show promise of slowing the progression of Alzheimer's disease.

But while patient advocates are celebrating, critics see it as the unfortunate triumph of a flawed theory of the disease's cause and predict the rollout of the drug will aggravate racial disparities in elder care.

An FDA advisory panel last month voted 6-0 to support FDA approval of lecanemab, from the Japanese pharmaceutical company Eisai. In a clinical trial involving nearly 1,800 early-stage Alzheimer's patients, the drug slowed progression of the disease somewhat in those who got biweekly infusions, with those given a placebo.

But the drug didn't reverse Alzheimer's symptoms, and it will require careful monitoring of patients for months or years, including many brain scans. Those receiving lecanemab, which carries the brand name Leqembi, were twice as likely as placebo recipients in the major trial to suffer hemorrhaging or swelling in the brain. These incidents, related to the drug's stripping away of amyloid proteins, were generally minor, but three deaths appear to have been caused by the drug.

With the FDA poised to give full approval to lecanemab and Eisai set to promote it to the primary care physicians who treat most dementia patients, critics are speaking out. Some say the drug, which Eisai plans to market for $26,500 a year, offers false hope. Others say any positive impact it has won't benefit lower-income patients, who tend to be diagnosed too late for the drug to be effective, and usually receive care in settings ill-equipped to handle the drug's stringent requirements.

“The most likely consequence of this medication is to take resources and attention away from addressing basic supports for older adults with cognitive impairment,” said Maria Glymour, chair of the Department of Epidemiology at the Boston School of Public Health. The money spent on expensive like lecanemab would be better invested in fighting diseases like high blood pressure and diabetes, which hasten dementia, and on community-based services for older adults, she said.

The critique of lecanemab builds on another complexity of the drug's approval: Few African Americans were involved in testing it.

Of the 859 people infused with lecanemab during the trial, only 20 were Black. Minorities are often underrepresented in research, but this study had an additional barrier, said Carey Gleason, a clinical neuropsychologist at the University of Wisconsin School of Medicine and Public Health. Many Black volunteers in the trial “screened out,” she said, because PET scans showed relatively low levels of amyloid in their brains. Lecanemab works by removing amyloid, so the trial organizers excluded patients — regardless of their Alzheimer's symptoms — if their PET scans were negative.

Eisai spokesperson Libby Holman said the company worked to enroll a diverse population but that amyloid levels “differed among racial and ethnic groups.” She added, “If individuals do not have elevated amyloid, they do not have Alzheimer's disease.”

Indeed, lecanemab's approval marks the culmination of the idea, formalized 32 years ago, that Alzheimer's disease can be understood as cognitive decline caused by amyloid buildup, the “trigger,” in combination with the “bullet,” a protein called tau.

For example, Blacks are up to twice as likely as whites to be diagnosed with Alzheimer's, while showing equivalent levels of amyloid in most major studies. No one is sure why, but the hypothesis is that having multiple simultaneous health conditions and being exposed to environmental stressors put Blacks as a group at higher risk.

Furthermore, Blacks and other minorities tend to be diagnosed at later stages, which automatically excludes them from use of lecanemab, which was designed and approved to treat early-stage Alzheimer's.

“The drug has to be used in the very early window of the disease,” Gleason said. “It's well documented that marginalized communities and people don't get access to diagnostic services as do more privileged populations, because our medical care is two-tiered.”

“Lecanemab should still to market,” she said. “But we need to be investing in other pathways.”

In its of the costs and benefits of lecanemab, a 15-member panel appointed by the Institute for Clinical and Economic Review gave the drug low marks. Its rollout would aggravate elder care disparities, the panel said, by favoring wealthier patients who have more resources, better insurance, and an easier time getting to multiple appointments.

Advocates for minority health care are well aware of these risks. But many feel the only response is to push harder for access to the drug. Black people whose conditions qualify them for the drug would do as well on it as whites, said Carl Hill, chief diversity, equity and inclusion officer for the Alzheimer's Association, which is raising awareness of the drug through churches and grassroots groups.

Manly is not so sure. “There are reasons to question whether it would be safe in Black people,” she said, noting that older Black people diagnosed with dementia have higher rates of vascular conditions like hardening of the arteries compared with white patients. That could pose potentially higher risks of brain hemorrhaging if they took the drug. In general, the trial's lack of representativeness across racial and ethnic groups means the drug may not perform as well against Alzheimer's disease across these groups, Manly said.

“In terms of equity I feel conflicted,” she said. “I'd love for all families like mine to have equitable access to an Alzheimer's drug, but only if it's safe and effective.”

Even the most optimistic Alzheimer's experts believe the drug's risks require careful selection of patients by highly trained clinicians with sufficient resources to detect and monitor any problems.

Jason Karlawish, a neurologist at the Perelman School of Medicine at the University of Pennsylvania, said the FDA should set up a Risk Evaluation and Mitigation Strategy, or REMS, which would require doctors administering the drug to follow a series of steps to reduce and monitor its dangers. A REMS, currently in place on about 60 drugs, generally limits access to a drug.

The conflict between safety and access is only one paradox of lecanemab's arrival.

The FDA approved an earlier anti-amyloid treatment, Aduhelm, in 2021. but most doctors rejected it as ineffective and unsafe. Some Alzheimer's scientists who have long argued that amyloid isn't the whole answer feel that lecanemab's middling performance only confirms their thesis.

One skeptic is George Perry, a neurobiology professor at the University of Texas at San Antonio. He has hypothesized that amyloid and tau buildup are a reaction to the aging process that play a role in preserving, rather than wrecking, the brain. The accumulation of amyloid in older people's brains, in Perry's view, reflects the body's effort to fight aging disease.

Dementia clearly has many causes, said S. Ahmad Sajjadi, a clinician and neuroscientist at the University of California-Irvine. Ideally, patients will someday receive treatments as specific and targeted as those increasingly available to treat cancers, he said.

For now, for a select group of patients, lecanemab offers a whisper of hope that some will want to pursue, despite the risks, Karlawish said — perhaps a 10% of freezing the progression of the disease for months or even longer.

Patient groups such as the Alzheimer's Association, which funds much of the research in the field, are demanding broad access to lecanemab and oppose the Biden administration's plan to have Medicare initially pay for the drug only if patients are enrolled in a registry, a kind of post-marketing clinical trial.

At a public hearing during the FDA advisory panel meeting on the drug, Alzheimer's Association Joanne Pike noted that patients on lecanemab declined five months more slowly in their first 18 months on the drug, on average. That “deserves celebration,” she said.

Perry, who has received research from the Alzheimer's Association, questions its strong support for the drug but isn't surprised, given the group's promise to its members and supporters to find a cure for the disease.

“They've pushed amyloid so hard for 30 years,” he said, “and they can't turn back.”

Medical Residents Are Increasingly Avoiding States With Abortion Restrictions

Isabella Rosario Blum was wrapping up medical school and considering residency programs to become a family practice physician when she got some frank advice: If she wanted to be trained to abortions, she shouldn't stay in Arizona.

Blum turned to programs mostly in states where abortion access — and, by extension, abortion training — is likely to remain protected, like California, Colorado, and New Mexico. Arizona has enacted a banning most abortions after 15 weeks.

“I would really like to have all the training possible,” she said, “so of course that would have still been a limitation.”

In June, she will start her residency at Swedish Cherry Hill hospital in Seattle.

According to new statistics from the Association of American Medical Colleges, for the second year in a row, students graduating from U.S. medical schools were less likely to apply this year for residency positions in states with abortion bans and other significant abortion restrictions.

Since the Supreme Court in 2022 overturned the constitutional right to an abortion, fights over abortion access have created plenty of uncertainty for pregnant patients and their . But that uncertainty has also bled into the world of medical education, forcing some new doctors to factor state abortion laws into their decisions about where to begin their careers.

Fourteen states, primarily in the Midwest and South, have banned nearly all abortions. The new analysis by the AAMC — a preliminary copy of which was exclusively reviewed by KFF Health News before its public release — found that the number of applicants to residency programs in states with near-total abortion bans declined by 4.2%, with a 0.6% drop in states where abortion remains legal.

Notably, the AAMC's findings illuminate the broader problems abortion bans can create for a state's medical community, particularly in an era of provider shortages: The organization tracked a larger decrease in interest in residencies in states with abortion restrictions not only among those in specialties most likely to treat pregnant patients, like OB-GYNs and emergency room doctors, but also among aspiring doctors in other specialties.

“It should be concerning for states with severe restrictions on reproductive rights that so many new physicians — across specialties — are choosing to apply to other states for training instead,” wrote Atul Grover, executive director of the AAMC's Research and Action Institute.

The AAMC analysis found the number of applicants to OB-GYN residency programs in abortion ban states dropped by 6.7%, compared with a 0.4% increase in states where abortion remains legal. For internal medicine, the drop observed in abortion ban states was over five times as much as in states where abortion is legal.

In its analysis, the AAMC said an ongoing decline in interest in ban states among new doctors ultimately “may negatively affect access to care in those states.”

Jack Resneck Jr., immediate past president of the American Medical Association, said the data demonstrates yet another consequence of the post-Roe v. Wade era.

The AAMC analysis notes that even in states with abortion bans, residency programs are filling their positions — mostly because there are more graduating medical students in the U.S. and abroad than there are residency slots.

Still, Resneck said, “we're extraordinarily worried.” For example, physicians without adequate abortion training may not be able to manage miscarriages, ectopic pregnancies, or potential complications such as infection or hemorrhaging that could stem from pregnancy loss.

Those who work with students and residents say their observations support the AAMC's findings. “People don't want to go to a place where evidence-based practice and human rights in general are curtailed,” said Beverly Gray, an associate professor of obstetrics and gynecology at Duke School of Medicine.

Abortion in North Carolina is banned in nearly all cases after 12 weeks. Women who experience unexpected complications or discover their baby has potentially fatal birth defects later in pregnancy may not be able to receive care there.

Gray said she worries that even though Duke is a highly sought training destination for medical residents, the abortion ban “impacts whether we have the best and brightest coming to North Carolina.”

Rohini Kousalya Siva will start her obstetrics and gynecology residency at MedStar Washington Hospital Center in Washington, D.C., this year. She said she did not consider programs in states that have banned or severely restricted abortion, applying instead to programs in Maryland, New Hampshire, New York, and Washington, D.C.

“We're physicians,” said Kousalya Siva, who attended medical school in Virginia and was previously president of the American Medical Student Association. “We're supposed to be giving the best evidence-based care to our patients, and we can't do that if we haven't been given abortion training.”

Another consideration: Most graduating medical students are in their 20s, “the age when people are starting to think about putting down roots and starting families,” said Gray, who added that she is noticing many more students ask about politics during their residency interviews.

And because most young doctors make their careers in the state where they do their residencies, “people don't feel safe potentially their own pregnancies living in those states” with severe restrictions, said Debra Stulberg, chair of the Department of Family Medicine at the University of Chicago.

Stulberg and others worry that this self-selection away from states with abortion restrictions will exacerbate the shortages of physicians in rural and underserved .

“The geographic misalignment between where the needs are and where people are choosing to go is really problematic,” she said. “We don't need people further concentrating in urban areas where there's already good access.”

After attending medical school in Tennessee, which has adopted one of the most sweeping abortion bans in the nation, Hannah Light-Olson will start her OB-GYN residency at the University of California-San Francisco this summer.

It was not an easy decision, she said. “I feel some guilt and sadness leaving a situation where I feel like I could be of some ,” she said. “I feel deeply indebted to the program that trained me, and to the patients of Tennessee.”

Light-Olson said some of her fellow students applied to programs in abortion ban states “because they think we need pro-choice providers in restrictive states now more than ever.” In fact, she said, she also applied to programs in ban states when she was confident the program had a way to provide abortion training.

“I felt like there was no perfect, 100% guarantee; we've seen how fast things can change,” she said. “I don't feel particularly confident that California and New York aren't going to be under threat, too.”

As a condition of a scholarship she received for medical school, Blum said, she will have to return to Arizona to practice, and it is unclear what abortion access will look like then. But she is worried about long-term impacts.

“Residents, if they can't get the training in the state, then they're probably less likely to settle down and work in the state as well,” she said.

Paid Sick Leave Sticks After Many Pandemic Protections Vanish

Bill Thompson's wife had never seen him smile with confidence. For the first 20 years of their relationship, an infection in his mouth robbed him of teeth, one by one.

“I didn't have any teeth to smile with,” the 53-year-old of Independence, Missouri, said.

Thompson said he dealt with throbbing toothaches and painful swelling in his face from abscesses for years working as a cook at Burger King. He desperately needed to see a dentist but said he couldn't afford to take time off without pay. Missouri is one of many states that do not require employers to provide paid sick leave.

So, Thompson would swallow Tylenol and push through the pain as he worked over the hot .

“Either we go to work, have a paycheck,” Thompson said. “Or we take care of ourselves. We can't take care of ourselves because, well, this vicious circle that we're stuck in.”

In a nation that was sharply divided about government mandates during the covid-19 pandemic, the public has been warming to the idea of government rules providing for paid sick leave.

Before the pandemic, 10 states and the District of Columbia had laws requiring employers to provide paid sick leave. Since then, Colorado, New York, New Mexico, Illinois, and Minnesota have passed laws offering some kind of paid time off for illness. Oregon and California expanded previous paid leave laws. In Missouri, Alaska, and Nebraska, advocates are pushing to put the issue on the ballot this fall.

The U.S. is one of nine countries that do not guarantee paid sick leave, according to data compiled by the World Policy Analysis Center.

In response to the pandemic, Congress passed the Emergency Paid Sick Leave and Emergency and Medical Leave Expansion acts. These temporary measures allowed employees to take up to two weeks of paid sick leave for covid-related illness and caregiving. But the provisions expired in 2021.

“When the pandemic hit, we finally saw some real political will to solve the problem of not federal paid sick leave,” said economist Hilary Wething.

Wething co-authored a recent Economic Policy Institute report on the state of sick leave in the United States. It found that more than half, 61%, of the lowest-paid workers can't get time off for an illness.

“I was really surprised by how quickly losing pay — because you're sick — can translate into immediate and devastating cuts to a family's household budget,” she said.

Wething noted that the lost wages of even a day or two can be equivalent to a month's worth of gasoline a worker would need to get to their job, or the choice between paying an electric bill or buying food. Wething said showing up to work sick poses a risk to co-workers and customers alike. Low-paying that often lack paid sick leave — like cashiers, nail technicians, home health aides, and fast-food workers — involve lots of face-to-face interactions.

“So paid sick leave is about both protecting the public health of a community and providing the workers the economic security that they desperately need when they need to take time away from work,” she said.

The National Federation of Independent Business has opposed mandatory sick leave rules at the state level, arguing that workplaces should have the flexibility to work something out with their employees when they get sick. The group said the cost of paying workers for time off, extra paperwork, and lost productivity burdens small employers.

According to a report by the National Bureau of Economic Research, once these mandates go into effect, employees take, on average, two more sick days a year than before a took effect.

Illinois' paid time off rules went into effect this year. Lauren Pattan is co-owner of the Old Bakery Beer Co. there. Before this year, the craft brewery did not offer paid time off for its hourly employees. Pattan said she supports Illinois' new law but she has to figure out how to pay for it.

“We really try to be respectful of our employees and be a good place to work, and at the same time we get worried about not being able to afford things,” she said.

That could mean customers have to pay more to cover the cost, Pattan said.

As for Bill Thompson, he wrote an op-ed for the Kansas Star newspaper about his dental struggles.

“Despite working nearly 40 hours a , many of my co-workers are homeless,” he wrote. “Without , none of us can afford a doctor or a dentist.”

That op- generated attention locally and, in 2018, a dentist in his community donated his time and labor to remove Thompson's remaining teeth and replace them with dentures. This allowed his mouth to recover from the infections he'd been dealing with for years. Today, Thompson has a new smile and a job — with paid sick leave — working in food service at a hotel.

In his free time, he's been collecting signatures to put an initiative on the November ballot that would guarantee at least five days of earned paid sick leave a year for Missouri workers. Organizers behind the petition said they have enough signatures to take it before the voters.

Forget Ringing the Button for the Nurse. Patients Now Stay Connected by Wearing One.

HOUSTON — Patients admitted to Houston Methodist Hospital get a monitoring device about the size of a half-dollar affixed to their chest — and an unwitting role in the expanding use of artificial intelligence in .

The slender, battery-powered gadget, called a BioButton, records vital signs heart and breathing rates, then wirelessly sends the readings to nurses sitting in a 24-hour control room elsewhere in the hospital or in their homes. The device's software uses AI to analyze the voluminous data and detect signs a patient's is deteriorating.

Hospital say the BioButton has improved care and reduced the workload of bedside nurses since its rollout last year.

“Because we catch things earlier, patients are doing better, as we don't have to wait for the bedside team to notice if something is going wrong,” said Sarah Pletcher, system vice president at Houston Methodist.

But some nurses fear the technology could wind up replacing them rather than supporting them — and harming patients. Houston Methodist, one of dozens of U.S. hospitals to employ the device, is the first to use the BioButton to monitor all patients except those in intensive care, Pletcher said.

“The hype around a lot of these devices is they care at scale for less labor costs,” said Michelle Mahon, a registered nurse and an assistant director of National Nurses United, the profession's largest U.S. union. “This is a trend that we find disturbing,” she said.

The rollout of BioButton is among the latest examples of hospitals deploying technology to improve efficiency and address a decades-old nursing shortage. But that transition has raised its own concerns, including about the device's use of AI; polls show the public is wary of health providers relying on it for patient care.

In December 2022 the FDA cleared the BioButton for use in adult patients who are not in critical care. It is one of many AI tools now used by hospitals for tasks like reading diagnostic imaging results.

In 2023, President Joe Biden directed the Department of Health and Human Services to develop a plan to regulate AI in hospitals, including by collecting reports of patients harmed by its use.

The leader of BioIntelliSense, which developed the BioButton, said its device is a huge advance with nurses walking into a room every few hours to measure vital signs. “With AI, you now move from ‘I wonder why this patient crashed' to ‘I can see this crash coming before it happens and intervene appropriately,'” said James Mault, CEO of the Golden, Colorado-based company.

The BioButton stays on the skin with an adhesive, is waterproof, and has up to a 30-day battery . The company says the device — which allows providers to quickly notice deteriorating health by recording more than 1,000 measurements a day per patient — has been used on more than 80,000 hospital patients nationwide in the past year.

Hospitals pay BioIntelliSense an annual subscription fee for the devices and software.

Houston Methodist officials would not reveal how much the hospital pays for the technology, though Pletcher said it equates to less than a cup of coffee a day per patient.

For a hospital system that treats thousands of patients at a time — Houston Methodist has 2,653 non-ICU beds at its eight Houston-area hospitals — such an investment could still translate to millions of dollars a year.

Hospital officials say they have not made any changes in nurse staffing and have no plans to because of implementing the BioButton.

Inside the hospital's control center for virtual monitoring on a recent morning, about 15 nurses and technicians dressed in scrubs sat in front of large monitors showing the health status of hundreds of patients they were assigned to monitor.

A red checkmark next to a patient's name signaled the AI software had found readings trending outside normal. Staff members could click into a patient's medical record, showing patients' vital signs over time and other medical history. These virtual nurses, if you will, could contact nurses on the floor by phone or email, or even dial directly into the patient's room via call.

Nutanben Gandhi, a technician who was watching 446 patients on her monitor that morning, said that when she gets an alert, she looks at the patient's health record to see if the anomaly can be easily explained by something in the patient's condition or if she needs to contact nurses on the patient's floor.

Oftentimes an alert can be easily dismissed. But identifying signs of deteriorating health can be tough, said Steve Klahn, Houston Methodist's clinical director of virtual medicine.

“We are looking for a needle in a haystack,” he said.

Donald Eustes, 65, was admitted to Houston Methodist in March for prostate cancer treatment and has since been treated for a stroke. He is happy to wear the BioButton.

“You never know what can happen here, and having an extra set of eyes looking at you is a good thing,” he said from his hospital bed. After being told the device uses AI, the Montgomery, Texas, man said he has no problem with its helping his clinical team. “This sounds like a good use of artificial intelligence.”

Patients and nurses alike benefit from remote monitoring like the BioButton, said Pletcher of Houston Methodist.

The hospital has placed small cameras and microphones inside all patient rooms enabling nurses outside to communicate with patients and perform tasks such as helping with patient admissions and discharge instructions. Patients can include family members on the remote calls with nurses or a doctor, she said.

Virtual technology frees up on-duty nurses to provide more hands-on help, such as starting an intravenous line, Pletcher said. With the BioButton, nurses can wait to take routine vital signs every eight hours instead of every four, she said.

Pletcher said the device reduces nurses' stress in monitoring patients and allows some to work more flexible hours because virtual care can be done from home rather than coming to the hospital. Ultimately it helps retain nurses, not them away, she said.

Sheeba Roy, a nurse manager at Houston Methodist, said some members of the nursing staff were nervous about relying on the device and not checking patients' vital signs as often themselves. But testing has shown the device provides accurate information.

“After we implemented it, the staff loves it,” Roy said.

Serena Bumpus, chief executive officer of the Texas Nurses Association, said her concern with any technology is that it can be more burdensome on nurses and take away time with patients.

“We have to be hypervigilant in ensuring that we are not leaning on this to replace the ability of nurses to critically think and assess patients and validate what this device is telling us is true,” Bumpus said.

Houston Methodist this year plans to send the BioButton home with patients so the hospital can better track their progress in the weeks after discharge, measuring the quality of their sleep and checking their gait.

“We are not going to need less nurses in health care, but we have limited resources and we have to use those as thoughtfully as we can,” Pletcher said. “Looking at projected demand and seeing the supply we have coming, we will not have enough to meet demand, so anything we can do to give time back to nurses is a good thing.”
