In Starr County, Texas, close to the state’s southern tip alongside the U.S.-Mexico border, escaping dementia can really feel unimaginable. The situation impacts about one in 5 adults on Medicare—greater than double the nationwide charge. “Everyone has any individual of their household” with dementia, Gladys Maestre, a neuroepidemiologist who research getting old on the College of Texas at Rio Grande Valley, informed me.

For Jessica Cantú, it was her father, Tomas. He requested her, his eldest daughter, by no means to place him in a nursing house. She promised. “We handle our personal,” she informed me. As Tomas’s dementia progressed, the previous pastor held to his routines. He performed along with his 19 grandchildren. He preached Wednesday-night providers and hand-delivered donations of rice, beans, and oil throughout the border. He fed his chickens and sheep, and ate his favourite home made meals—pineapple upside-down cake, enchiladas with saltine crackers, and cream-of-mushroom hen over rice.
Dementia looms over the Cantú household tree. Two of Tomas’s 10 siblings had it; Jessica questioned whether or not extra might need, in the event that they’d lived longer. Her maternal grandmother had dementia too. Seven months after her dad’s dying, she started working as a nurse practitioner on the county’s first personal Alzheimer’s-specific analysis web site, El Faro Well being and Therapeutics. “Sufferers will are available and say, ‘So have you ever figured it out? What’s it?’” she informed me. She tells them the reality. “I don’t know what it’s that’s inflicting all of this.”

Dementia has no single set off. As with many cancers, it will probably emerge from a lifetime of gathered pressure—from genetics, surroundings, and conduct. Researchers have recognized a dozen threat components that, if mitigated, might theoretically delay or forestall roughly 40 p.c of instances worldwide: traumatic mind harm; circumstances together with hypertension, listening to loss, diabetes, and despair; habits akin to smoking, inactivity, and heavy consuming; environmental and social forces together with air air pollution, social isolation, and restricted schooling.
These “threat components often don’t come [as] one; they arrive in clusters,” Maestre stated—and in Starr County, an nearly fully Hispanic group, they shortly stack up. Almost one in three folks lives in poverty; 1 / 4 lack medical insurance. Continual circumstances are widespread—particularly diabetes, hypertension, and coronary heart illness—whereas entry to care is restricted: There’s only one primary-care doctor for each 3,000 to 4,000 folks, and few dementia specialists. Low schooling, language obstacles, poor air high quality, and excessive warmth all compound the risk. These accumulate in cycles of grief and stress: The folks I spoke with talked about deaths within the household adopted by strokes that cascade into cognitive decline. Dementia isn’t merely a analysis. It’s a structural final result.
Nonetheless, many in Starr County battle to make sense of it. And irrespective of the trigger—irrespective of which conglomeration of causes—they need to dwell with dementia’s actuality.

Garza-Ray retired in 2023 from her job as a nurse at an assisted-living facility in Rio Grande Metropolis, Texas, the place many sufferers have Alzheimer’s; she believes stress and poor vitamin are ignored threat components for dementia.

In the Rio Grande Valley, persons are additionally outliving their odds. The realm’s excessive dementia charge, Maestre has come to imagine, might replicate not simply threat however endurance: folks residing longer with the situation.
Basically, analysis exhibits that Hispanic folks are likely to dwell longer than non-Hispanic white folks, regardless of dealing with greater charges of power illness and steeper socioeconomic disadvantages—a sample typically referred to as the “Hispanic paradox.” And within the Rio Grande Valley, a part of what would possibly maintain folks by dementia, Maestre suspects, is the tradition: Dementia is seen much less as a medical emergency and extra as a pure, if tough, section of life. Elsewhere, folks with dementia might dwell in nursing properties or take costly new Alzheimer’s medicine with modest profit. In Starr County, many older adults stay at house, surrounded by household who supply familiarity and stimulation. The care is bodily, intimate—not medical, however fixed—and backed by analysis displaying that acquainted environments and home-based care can improve each high quality of life and cognitive operate for folks with dementia.
“He was by no means, by no means—for the reason that day I introduced him to my house—he was by no means sooner or later alone,” says Juan “Manny” Saenz of his father, Francisco “Pancho,” who died at house final month at age 94. Knowledgeable body-shop painter, offshore fisherman, and lifelong jokester, Pancho started to develop forgetful and repetitive a few decade in the past. Earlier than Manny’s mother, Amaro, died, she made him promise to not put his father in a nursing house. Below Manny’s care, Pancho’s look was impeccable: He was bathed and perfumed, with trimmed nails and a neat mustache. He ate his meals on ceramic dishes, and relished his coffee-and-cookie merienda snack break—or breaks, on days he’d neglect the earlier ones. Manny, who lives in Rio Grande Metropolis, informed me precisely what Jessica Cantú had: “We handle our personal.”

Juan “Manny” Saenz helps his dad, Francisco “Pancho,” use the toilet in Manny’s house in Rio Grande Metropolis in December 2023. A couple of months earlier, Manny was sitting exterior the identical rest room whereas his father sat on the bathroom, they usually had been comic-bickering, as they typically did, with exaggerated insults and playful lies. Then Pancho stated, “Hijo, I all the time cherished you,” Manny recalled. “By no means in my complete life has my dad stated he cherished me.” Manny laughed. “Afterwards, we return to our similar routine.”

Pancho’s daughter, Carmen Saenz-Lopez, kisses her dad when visiting to assist Manny with caregiving duties in November 2023. She and Pancho used to spend time collectively wandering the aisles of Residence Depot as he examined instruments and studied sandpaper. “Once we left, typically he would purchase only a bag of nails,” she stated. In his final years, Pancho hardly ever left Manny’s house.

Carmen rests her palms on prime of her dad’s in November 2023. “I keep in mind him doing hand puppets with a fuel lamp throughout a thunderstorm once we misplaced electrical energy,” she stated. “And he would put his hand underneath his armpit and make that sound. He all the time had a humorousness.”
Monica Saenz Silva made an analogous resolution for her mom, Ramona—a bookkeeper at coronary heart, the type of one that stored each receipt for taxes and reminded her grownup youngsters to alter their tires. She stored a operating calendar of birthdays, not only for household and associates, but in addition for acquaintances, so she might want them properly. By 2019, a number of years after her dementia signs appeared, “that was out the door,” Monica informed me.
As we speak, Ramona will strategy a taco or hamburger quizzically; she’s forgotten the best way to chew into them. At occasions, she doesn’t acknowledge the home the place she’s lived for many years. Nonetheless, Monica is decided to maintain her there. “You need to maintain them house, so that they’re in a well-known surrounding,” she stated. “It’s not on a regular basis that she doesn’t know she’s house.”
The response of many households right here to dementia is formed, partly, by restricted therapy choices: Alzheimer’s and associated dementias haven’t any treatment, and obtainable medicines will be costly, be restricted of their advantages, and include doubtlessly life-threatening unwanted side effects. In Starr County, some caregivers eschew prescription drugs for fragrant teas, natural compresses, and prayers to assuage family members, Maestre stated. Theirs is an ethic of endurance: If dementia is right here, households ask, why not construct a life, tenderly, round it?
Nonetheless, many don’t converse of it overtly. Cantú informed me that in her group, many nonetheless take into account Alzheimer’s to be a standard a part of getting old—at most, a psychological sickness of previous age, however nearly by no means a neurodegenerative illness. “It’s okay to simply be forgetful on the age of 70. It’s okay as a result of Grandma and Grandpa had been forgetful on the age of 70,” she stated. “There’s no motive to debate it.”
Nonetheless, some caregivers dwell with a way of dread: In lots of instances, the illness does have a genetic part, and the structural forces that compounded their family members’ threat haven’t disappeared. They know their flip could possibly be coming. Cantú frets about her thoughts; Monica Saenz Silva checks her reminiscence every single day. And so they don’t essentially need for themselves what they did for his or her mother and father: If his time comes, Manny Saenz needs to go to a nursing facility. “You received’t know something, so it doesn’t matter,” he stated. For him, the individual with Alzheimer’s is spared the reminiscence of their decline; the burden belongs to those that keep in mind, and that’s a threat he doesn’t need to cross on.

Hispanic People face a considerably greater threat of dementia than white People, and are additionally one of many nation’s fastest-aging teams. And but, for many years, scientific understanding of dementia has drawn from knowledge from largely white, city, and prosperous populations; Hispanics make up fewer than 5 p.c of members in Alzheimer’s medical trials. That limits researchers’ understanding of the situation. And the extra they appear, the much less dementia looks like a single illness with a uniform sample, and the extra it seems to be a spectrum of illnesses—every unfolding with its personal course of signs, development, and mind injury.
In some research, researchers have detected amyloid plaques—the sticky protein clumps lengthy thought of hallmarks of Alzheimer’s—extra continuously within the brains of white members with dementia or gentle cognitive impairment than of their Black, Asian, or Hispanic counterparts. In a number of research that measured tau proteins, one other key Alzheimer’s biomarker, Black adults with—or with out—signs of dementia had decrease ranges than white members. The genetic variant most strongly linked to Alzheimer’s illness is much less widespread—and presumably much less potent—amongst folks with sure Hispanic backgrounds than amongst white folks.
In 2021, the Nationwide Institute on Growing older designated a brand new Alzheimer’s Illness Analysis Middle in South Texas, co-directed by Maestre and Sudha Seshadri, a neurologist on the College of Texas at San Antonio. Their objective is to grasp the Rio Grande Valley’s dementia cluster—and what will be achieved about it—partially by inspecting the results of environmental hardship and linguistic isolation, and by investigating protecting components akin to bilingualism and household networks.

Gladys Maestre, who directs the Alzheimer’s Illness Useful resource Middle for Minority Growing older Analysis on the College of Texas at Rio Grande Valley, walks by a area exterior the college’s neuroscience institute in Harlingen, Texas, in December 2023. Her aspirations lengthen past the lab: She envisions medical researchers gathering knowledge door-to-door in susceptible neighborhoods over a decade or extra. “Finally,” she stated, “I would like much less stress, more cash in folks’s pockets, higher meals, artwork on the street—all of it as assist and stimulation for the mind.”

Maestre seems at an MRI scan on the college’s neuroscience institute. Maestre is annoyed by a scarcity of analysis that she thinks is required to make progress in understanding the illness because it seems in Starr County and its neighboring counties. “When you’ve a cluster of individuals,” she stated, “you need to ask: The place is it coming from?”

Kevin Bieniek, the director of the mind financial institution on the Glenn Biggs Institute for Alzheimer’s and Neurodegenerative Ailments, in San Antonio, Texas, prepares slices of a dissected human mind to be photographed in December 2023. Autopsying a affected person’s mind may also help definitively diagnose Alzheimer’s illness.
Ultimately, Maestre hopes that city design (akin to shaded walkways, gardens, and areas for intergenerational interplay) might assist scale back the area’s dangers. “It’s not attainable to place all of the accountability on the person,” she informed me. “You can’t try this by yourself.”
And but, sources stay scarce. Texas is house to about 460,000 folks residing with Alzheimer’s illness, however in contrast with different giant states akin to Florida and New York, it spends a lot much less on dementia-related packages. (The Texas statehouse is contemplating a invoice to ascertain a $3 billion fund for dementia analysis.)
For now, households like Jessica Cantú’s are left to do what they’ll. When her father was a pastor, he would inform her in regards to the sick folks he visited who would attain up with their arms (towards the dominion of heaven, he stated) earlier than dying peacefully. Within the remaining weeks of his life, he was nonetheless going to church and chatting with folks on the H-E-B grocery retailer. However then Tomas misplaced his urge for food and grew frail. One night time, Jessica stored vigil at his bedside, afraid he’d fall making an attempt to rise up. Within the quiet hours, she stated, he lifted each arms towards the ceiling. “He was reaching as much as the heavens, to the sky,” she stated. “It simply gave me that consolation to know that he was prepared, and that all the pieces was going to be okay.”
