BROWNSVILLE, Texas — Gladys Maestre is on a scouting mission. The Alzheimer’s illness researcher is driving by way of Southmost, a Mexican American neighborhood simply north of looming sections of the border wall and a checkpoint that results in Mexico. She passes barking canine and “no trespassing” indicators, however doesn’t see a single particular person outdoors, regardless of the snug stuffed recliners, fridges, and shade canopies that furnish many yards.
“A home outdoors the home,” Maestre laughs, delighting in seeing these elaborate dwelling areas whereas acknowledging that the clear wariness of outsiders right here demonstrates the necessity for her unorthodox strategy to partaking the individuals she research. “That’s the place we may put a group middle,” she says, pointing to a vacant home. “For yoga, or artwork lessons.”
For many years, and actually for so long as the sphere has existed, Alzheimer’s researchers have recruited sufferers for scientific trials in largely the identical manner: pulling them from specialty clinics, usually at elite medical establishments that home the majority of the nation’s federally funded Alzheimer’s Illness Analysis Facilities. That’s led to sufferers in these trials, which typically provide new therapies obtainable by way of no different channels, being overwhelmingly privileged, well-insured, and white.

It’s an strategy that’s been more and more criticized for its lack of inclusion. Hispanic individuals, for instance, make up greater than 18% of the U.S. inhabitants, and are amongst teams extra prone to get Alzheimer’s illness, but accounted for simply 2% of members in Alzheimer’s scientific trials as of 2019.
Maestre got here to Texas’ Rio Grande Valley to alter that. With among the nation’s highest charges of Alzheimer’s illness amongst Hispanic individuals and a inhabitants that’s greater than 90% Mexican American, this may appear to be a straightforward place to recruit Hispanic sufferers to hitch research. However that hasn’t been the case. When Maestre met with colleagues not too long ago to research recruitment information, they realized that even right here, the place Spanish is the lingua franca and a few cities have virtually no white residents, 60% of sufferers desirous about collaborating in analysis are white — possible as a result of they, too, had been recruited from college well being clinics.
Whereas her group nonetheless has recruited much more Hispanic individuals than different facilities have, the numbers are clear proof, mentioned Maestre, that the usual methodology of enlisting individuals for Alzheimer’s analysis is damaged.

“It’s the modus operandi of 99% of Alzheimer’s facilities. Excessive-risk sufferers get sick, go to the physician, and get invited to take part,” she mentioned. “It’s inspired by the NIH as a result of it’s cheaper, however that is why there are not any Hispanics. It’s essential to go to the inhabitants.”
That’s precisely what Maestre plans to do. A deeply revered Alzheimer’s researcher, Maestre left a college place at Columbia College in New York Metropolis in 2016 to hitch the fledgling College of Texas Rio Grande Valley Faculty of Medication and instantly began constructing an bold analysis program with greater than $6 million she obtained from the Nationwide Institutes of Well being. Then in 2021, Maestre was awarded, with Sudha Seshadri, a professor of neurology on the College of Texas Well being Science Heart at San Antonio, $14.8 million to open an Alzheimer’s Illness Analysis Heart (ADRC) with areas within the Rio Grande Valley and in San Antonio.
That middle’s new clinics and analysis labs opened final fall simply north of Brownsville, in Harlingen. Maestre plans to make use of the brand new facility and funding to rethink, and maybe upend, who’s studied in Alzheimer’s analysis and the way. Her group is beginning to go door-to-door by way of the Southmost neighborhood to inform them about obtainable sources for well being points together with Alzheimer’s illness, and about alternatives to participate in analysis. She’s hoping to incorporate individuals as younger as 40 who could also be at completely different levels of Alzheimer’s, ensuring to not examine solely individuals with illness so superior they’ve needed to search medical care. She’s additionally on the lookout for clusters of illness, indicators that the setting could play a bigger position within the improvement of Alzheimer’s than historically believed.
Her aim is to broaden the main target many Alzheimer’s researchers have had on a single gene or protein — work she sees as counterproductive shortcuts that haven’t yielded a deep understanding of the illness. And don’t get her began on the sphere’s long-held obsession with clumps of amyloid proteins as a precursor of illness, a clubby focus that sucked oxygen, and grant cash, from those that wished to check different elements. “We wish to remedy Alzheimer’s illness with out understanding it, with out strolling the trail,” she mentioned.
Whereas researchers at her middle and in San Antonio are finding out a bunch of genes and biomarkers that could be concerned within the illness, Maestre can also be pursuing a extra holistic strategy — utilizing state-of-the-art methods to look at the contributions of vascular illness, energy of household ties, environmental pollution, and the material of neighborhoods, and doing so in a inhabitants that has lengthy been missed. The work right here, she hopes, may pace the hunt for therapies and methods to forestall Alzheimer’s.
“If we deliver variety, not simply examine the field, however embrace the experiences of those individuals, we’ll have a greater probability of understanding what’s affecting reminiscence,” she mentioned.
That would profit all populations. As soon as sufferers are recruited right here, their blood samples and mind pictures will likely be despatched to a nationwide tissue repository, serving to to diversify a group utilized in quite a few Alzheimer’s research.
Seshadri notes that taking a look at particular person teams can serve a bigger inhabitants; a category of ldl cholesterol medicine referred to as PCSK9 inhibitors arose from findings that some Black members enrolled within the Dallas Coronary heart Examine had genetic mutations that led to extraordinarily low levels of cholesterol. “Solutions you discover hiding in individuals you haven’t studied could possibly be invaluable solutions not simply to them however to everybody. That’s the worth of variety,” she mentioned.
It’s not as if Maestre is the one scientist finding out Alzheimer’s in Hispanic populations. (Biogen and Eisai, for instance, mentioned Tuesday evening that about 25% of members of their scientific trial of an experimental therapy referred to as lecanemab had been Hispanic or Black individuals.) However most ADRCs have not more than a smattering of researchers centered on such teams. Right here, geography is essential, the work is community-based, and the native Mexican American inhabitants is the singular focus.
“If we deliver variety, not simply examine the field, however embrace the experiences of those individuals, we’ll have a greater probability of understanding what’s affecting reminiscence.”
Gladys Maestre, Alzheimer’s researcher
Alzheimer’s researchers across the nation are eagerly awaiting the brand new samples that come from this inhabitants but additionally avidly watching how and what Maestre does. The nation’s main funder of Alzheimer’s analysis, the Nationwide Institute on Growing old, has wager on Maestre with hundreds of thousands in funding, hoping her work improves, and even revolutionizes, how analysis is performed.
“She is aware of that is her second,” mentioned Cerise Elliott, who co-leads the ADRC program on the institute. “If she’s going to make a distinction, now could be the time. She’s utilizing this runway to be daring and actually visionary.”
First, although, she has to get individuals to open their doorways.
Maestre’s adopted house is a spot of deep pure magnificence. Native grasses and palm timber sway within the wind. Inexperienced waters lap in resacas, former meanderings of the Rio Grande now reduce off from the river, which cool neighborhoods alongside their banks. However it’s additionally an space with entrenched poverty, a extreme scarcity of medical care, and staggeringly excessive charges of Alzheimer’s illness: Two of the valley’s counties rank among the many highest within the nation for charges of the illness amongst Hispanic individuals.
It’s unclear precisely why instances within the valley are so frequent. The chance elements for residents jumble towards one another like so many fallen blocks: Low training. Low family revenue. Lack of entry to protected areas for strolling or train. Excessive charges of diabetes. Weight problems. Dependancy. Air air pollution. Poisonous metals within the ingesting water.
Many residents, like 51-year-old Alma Castor, stay in colonias, neighborhoods of cell houses and self-built buildings that lie outdoors of metropolis limits and sometimes lack fundamental providers comparable to operating water, sewers, and trash disposal. Medical care, as it’s for Castor, is usually an afterthought.
She hasn’t seen a doctor regionally for 14 years, Castor mentioned, since she had her final little one, however will typically cross the border for medical care she will afford in Mexico: $25 for a health care provider’s go to and $15 for prescriptions just like the albuterol inhalers so many in her household must breathe amid bronchial asthma assaults.
Castor, who forded the Rio Grande as a younger girl and is now a authorized U.S. resident, has labored arduous all her life. She put most of her kids by way of faculty, however nonetheless cares for her youngest, who’re in highschool, and a grandson with Down syndrome in a small house that carries watermarks from latest flooding.
Like virtually everybody right here, Castor is aware of a number of individuals with dementia. A person she works with not acknowledges her. A neighbor she used to see wandering among the many horses and goats that roam the colonia walked off in the future and was by no means seen once more. Her personal kids are frightened she could have dementia as nicely. She’s gotten confused and misplaced a couple of occasions whereas out driving, she mentioned. Her sons now observe her telephone so she will name them if she must be guided house. However it’s nothing she’s planning to see a health care provider about.
Given how tough it’s for residents like Castor to entry well being care, Maestre thinks the disturbingly excessive charges of Alzheimer’s listed here are possible an undercount. Regardless of the true numbers, they’re prone to rise. With the U.S. Hispanic inhabitants anticipated to triple by 2050 — and age — the Facilities for Illness Management and Prevention estimates that 3.2 million Hispanic individuals could have Alzheimer’s by 2060. A lot of them are anticipated to stay within the south, and in rural areas like this one.
But the nation’s 33 Alzheimer’s Illness Analysis Facilities, which examine causes of the illness and provide entry to scientific trials of experimental remedies, are situated principally in additional privileged settings in city facilities and alongside the coasts — and never essentially in areas with the very best Alzheimer’s case charges. California has six, New York Metropolis has three, and Boston has two. Till the South Texas Alzheimer’s Illness Analysis Heart opened right here final fall, Texas didn’t have a single one.
To say Maestre thinks and operates in a different way than the everyday researcher is an understatement. She’s as prone to be discovered presenting at a scientific convention as she is judging a fajita contest. She’ll point out tau proteins and the Renaissance artist Tintoretto in the identical breath. She thinks scientists want to speak much less about molecules and extra about love.
On a latest day, she drove practically 300 miles throughout her huge territory: the 43,000-square-mile Rio Grande Valley. First she met with Tony Falcon, who has practiced household drugs for 43 years in rural Starr County, certainly one of Texas’ poorest, the place 18.9% of Latino residents on Medicare are estimated to have Alzheimer’s illness; that’s the second highest county price for Latinos within the nation after Miami-Dade.
Falcon was so pissed off at not with the ability to provide his sufferers something for his or her dementia — he calls it “a loss of life penalty analysis” — that he’s devoted many hours to arrange a scientific trial website in a constructing close to his follow in Rio Grande Metropolis. His workplace is so distant he can’t get the radioactive chemical substances wanted to run a PET scan to substantiate a affected person has Alzheimer’s, so he should use extra painful lumbar punctures as an alternative. “At the least I’ve one thing obtainable,” he mentioned of the experimental medicine he can provide sufferers by way of the trials, “apart from nothing however unhealthy information.”
Maestre then traveled with an architect to San Ygnacio, a virtually 200-year-old outpost of sandstone buildings in Zapata County on the banks of the Rio Grande. It’s house to artists, historic preservationists, and some hundred individuals, lots of them wholesome centenarians. They met with native artists and civic leaders to develop plans to make use of the distinctive group to check her idea that its labyrinthian streets could require reminiscence duties and navigation that preserve growing old brains wholesome.
With a relentless mental curiosity and a penchant for asking questions outdoors, in addition to inside, the lab, there appears no finish to the connections Maestre makes, or the questions she asks in her lilting Venezuelan accent. What’s the psychological influence of taking a look at a border wall? Why have human brains appreciated some painters — Tintoretto, for instance — for 600 years? May “reverse dippers,” individuals who have decrease blood strain at evening than they do through the day, be in danger? Is sleep apnea a lacking piece of the puzzle?
“Dr. Maestre is a power of nature. What she is constructing goes to resonate throughout ADRCs — and throughout the nation,” mentioned Jonathan Jackson, who directs the Group Entry, Recruitment, and Engagement Analysis Heart at Massachusetts Basic Hospital and has been a fierce critic of each the shortage of variety in Alzheimer’s analysis and the reluctance of many established researchers to alter the established order. “She doesn’t get the credit score she deserves.”
Maestre was born in Venezuela, the place she obtained a medical diploma from the College of Zulia in her hometown of Maracaibo, and remains to be recognized for her long-term examine of reminiscence issues among the many coastal metropolis’s residents. She discovered excessive charges of Alzheimer’s amongst residents and was among the many first researchers — many years in the past — to search for connections between cardiovascular and mind well being. In a time when most researchers centered on brains from autopsies, she helped pioneer using 24-hour blood strain screens in growing old, a software now seen as more and more promising.
She got here to the U.S. to get her Ph.D. in neurobiology and habits from Columbia, then did analysis on the Harvard-affiliated Mass. Basic and labored at Columbia. She was on the standard path to educational success, and colleagues there advised her she was loopy to go away again in 2016. However when she visited South Texas, she was captivated by the nice and cozy local weather, plentiful hospitality, and other people with deep connections to household, all issues that appeared a lot like Venezuela. “It was déjà vu, like coming house,” she mentioned. (Returning to Venezuela was not an possibility given the shortage of assist for science underneath latest authorities leaders and the lawlessness; rigorously collected tissue samples from her Maracaibo undertaking have fallen prey to freeway bandits when being shipped by truck.)
“A couple of people all the time get talked about, they get the most important grants and work on the greatest establishments, then you have got somebody like Gladys, who bucks that development, who leaves Columbia to go to a Hispanic-serving establishment in a spot surrounded by illness the place individuals actually need assistance,” mentioned Jason Resendez, who labored intently with Maestre because the founding director of the UsAgainstAlzheimer’s Heart for Mind Well being Fairness. “She has a grit about her and a dedication to group.”
Maestre’s work is rooted in a deep humanism and take care of the individuals she research. When strolling by way of the Brownsville neighborhood, for instance, she lamented the vans barreling towards the border on an adjoining road and the infinite stream of automobiles and fast-food eating places that stretched so far as the attention may see. The influence of such environments, with no sidewalks or locations to assemble, should influence mind well being, she thinks. “The place are the cafes?” Maestre requested wistfully. “The place can they stroll?”
“She talks about how the whole lot Venezuela has gone by way of has one way or the other ready her for this, for working on the U.S.-Mexican border, an space of deep human want and disaster,” mentioned her co-director Seshadri, a famous neurologist who was recruited to Texas from Boston the place she helped run the well-known Framingham Coronary heart Examine. “She has a capability to see challenges on the bottom and discover one of the best ways to reply these challenges.”
These challenges embrace untangling the mosaic of illnesses right here, together with diabetes and coronary heart illness, that could be a part of the rationale for top Alzheimer’s charges. Many individuals with these comorbidities have been excluded from research of the degenerative mind illness previously as a result of their well being points difficult analyses. This multifactorial complexity has been a problem for the sphere, however Maestre mentioned she has recruited a group of scientists who’ve the statistical chops to energy by way of the analyses she’s proposing.
Maestre is aware of the work right here received’t be straightforward. She is aware of many doorways in Southmost and elsewhere will keep closed regardless of her greatest efforts, and that solutions to most of the questions she is asking will take years to unravel, definitely for much longer than the everyday size of an Alzheimer’s analysis grant. “The very best story you’re going to get from me,” she advised STAT, “will likely be in 10 years.”
It’s not stunning that Maestre has discovered individuals reluctant to enroll in analysis research. For one, there’s an comprehensible wariness of strangers right here, the place getting stopped by the border patrol is frequent, and the river is monitored by huge blimps. Many residents are frightened of Alzheimer’s and in denial. Their first intuition is to not search assist however to maintain affected kinfolk hidden away. “They suppose in the event that they don’t speak about it, it’s going to go away,” Maestre mentioned.
And lots of don’t depend on the American well being care system as a result of it’s too costly or to not be trusted. They cross the border to see physicians, depend on folks healers referred to as curanderos, or go to herbalists to get treatments like Yerba santa, “the holy herb.” Maestre is usually shocked by the questions she will get about what she’ll do with blood samples. “They are saying, ‘Is that this like Jurassic Park? Will you make my twin?’” she mentioned.
Her secret weapons are promotoras, educated group well being employees who stay within the areas the place they work. They’ve historically centered on serving to neighbors with diabetes and most cancers, however are being educated right here about Alzheimer’s and different psychological well being circumstances comparable to melancholy and substance use dysfunction. They’ve begun knocking on doorways in Southmost to introduce themselves and inquire about who could also be impacted by Alzheimer’s and desirous about studying about Maestre’s analysis. It’s sluggish, cautious work as a result of many individuals listed here are nervous, afraid of each the illness and the curiosity of outsiders.
Maestre’s group has been holding focus teams to be taught why persons are staying away and what would possibly assist deliver them in. “They mentioned they don’t wish to be touched,” Karla Lopez, a analysis affiliate and doctoral candidate, mentioned at a latest assembly the group held to debate affected person enrollment. “They mentioned, ‘Blood pattern? No.’”
For Maestre, meaning in search of out phlebotomists with “the softest fingers.” For people who find themselves afraid of the phrase Alzheimer’s, it means discussing “reminiscence issues” as an alternative. For older individuals who say they’re too scared to be scanned inside an MRI machine, it means discovering workers who will maintain their fingers all through the process.
One other problem comes from the for-profit plasma facilities that dot the valley, the place billboards learn “Plasma: Good for You. Nice for Life” and other people can earn $700 to $900 a month promoting their plasma. For some residents, mentioned Maestre, “it’s a job.” And it means individuals prepared to provide blood samples to researchers usually anticipate to be paid massive sums. Her finances doesn’t allow paying such charges so she’s on the lookout for different incentives she will provide.
Some individuals ask if Maestre can get their relations new medicine like Aduhelm, although it’s seen as having questionable profit. She will be able to’t at this level as a result of it’s solely given at particular scientific trial websites, however she’s desirous to hearken to what else they could want. “They wish to speak, to cry, to share,” she mentioned. “I could also be desirous about Alzheimer’s. They could be desirous about how you can get their grandson therapy for dependancy, or in imaginative and prescient, glaucoma therapy, and cataracts.”
She needs residents to see the analysis middle as not only a medical workplace, however as a invaluable a part of their group. She’s organized for sufferers and their households to get free entry to an area zoo and artwork museum. She’s looking for a venue for abuelas — grandmothers — to promote their arts and crafts to earn cash. She provides analysis members lovely china dolls she’s collected. Accustomed to writing scientific grants that usher in hundreds of thousands, she’s been recognized to assist group teams write grants that web just some thousand {dollars}. “For them, it’s huge,” she mentioned. “I would like individuals to see us as a useful resource. Our doorways are open. Everybody has my cell.”
Yet one more recruitment drawback right here is machismo. Alzheimer’s is extra frequent in ladies, however in practically all Alzheimer’s research, males make up nearly all of members. Right here, males should not that ; they account for simply 33% of people that have signed up. “They suppose in the event that they ask for assist, it’s going to take their manhood,” Lopez advised STAT.
To Maestre, it’s not solely a logistical drawback, it’s one more analysis query to probe. “Let’s take into consideration this, what are the explanations?” she requested the group throughout its latest assembly. “Let’s look underneath the hood.”
To get across the resistance, she’s making an attempt to enchantment to males’s teams and the altruism that runs by way of this group, the place native charities gave $15 million towards the brand new Institute of Neuroscience the place the ADRC is housed and donated the 35 acres that the constructing stands on. She asks her husband, an immigration lawyer, to provide displays about Alzheimer’s analysis at males’s church teams. Alan Francis, a neuroscientist who not too long ago moved right here from Harvard, not too long ago spoke in regards to the want for analysis topics on the Harlingen Chamber of Commerce. “They took my playing cards and mentioned they might name us again,” he advised Maestre.
“I already obtained 5 emails,” Maestre mentioned triumphantly. “We’re going to discover ways to speak to males.”
The Institute of Neuroscience constructing in Harlingen has Maestre’s contact throughout it. As part of the design group, she insisted on using bricks that echoed the historic structure of the area and requested for the constructing’s artwork choices to incorporate the work of native artists. The home windows overlook fields of sunflowers, and there are benches for sufferers and caregivers to sit down outdoors. The within has a pharmacy, MRI, labs, and instruments starting from eye-tracking machines to Maestre’s beloved 24-hour blood strain trackers.
The bold work right here will, after all, take way more than a gleaming constructing and glossy equipment. It can take researchers who not solely perceive, however are a part of, this group. Maestre is keen on mentioning, even within the midst of a scientific speak, that fewer than 5% of researchers funded by the NIH are Hispanic. Right here, the school record seems very completely different.
Mario Gil is finding out the position of a gene referred to as AVPR1A in cognitive efficiency. Juan Lopez-Alvarenga is finding out vascular dementia. Marcio Almeida is on the lookout for new biomarkers that predict dementia danger. Romeo Luis Escobar is finding out stresses on Mexican American caregivers. Ney Alliey Rodriguez is combining analysis on the genetic underpinnings of Alzheimer’s with work on biomarkers and way of life elements to be taught when individuals begin to decline, and why. Alvaro Diaz-Badillo is testing whether or not eye monitoring could assist predict dementia. Candace Robledo, who was born right here within the Rio Grande Valley however left to earn her doctorate and full an NIH postdoctoral stint, has returned to check what position the pesticides and different industrial or carcinogenic chemical substances implicated within the excessive price of start defects right here could play in Alzheimer’s. Two extra Hispanic scientists, one from Venezuela and one from Tijuana, had been simply employed.
Previously, many researchers from the north would descend on the area to conduct research on the native inhabitants, usually with a brusqueness and lack of regard locals nonetheless complain about. They usually wouldn’t even inform individuals right here in regards to the outcomes of their research.
“They got here, did the analysis, no matter they wished, and left. It left a nasty style,” mentioned Noe Garza, the middle’s group liaison. “We’re right here. It’s completely different. We’re not going to go away. By no means.”
The work, this intensive and private recruitment of sufferers, the aim of growing a broader view of the numerous elements which will work together to trigger Alzheimer’s illness and in addition what could stop it, could be exhausting.
At occasions, Maestre asks herself why she’s pushing so arduous. It might be a lot simpler to conduct analysis the way in which it’s all the time been finished, merely specializing in established clinic sufferers. It might additionally make monetary sense. Many facilities, she famous, get reimbursed by insurers to deal with or assess sufferers, and are then paid once more to analysis them. “Why do I wish to make my life tougher? Am I paying some imaginary debt?” she requested.
However she is aware of the reply. On this valley that’s now Maestre’s everlasting house, Alzheimer’s and the devastation it wreaks are so palpable it might damage. And the individuals right here seem like her.
