Why a life-threatening sedative is being prescribed more often for seniors



Rutgers University




When agitated dementia patients wander or shout through the night, families and caregivers understandably feel the need to treat this frightening and potentially dangerous behavior.  Antipsychotic medications are often resorted to with such patients, contributing to increases in antipsychotic treatment rates among older people.

Indeed, a research letter by Rutgers and Columbia University researchers in JAMA Psychiatry shows those prescriptions are becoming more common in the United States, even though antipsychotic drugs do little for dementia and carry a black-box warning on their labels stating they increase the risk of death in senior patients.

Using a national prescription-claims database that captures more than 90% of retail pharmacy fills, researchers tracked antipsychotic use among adults 65 and older from 2015 through 2024 and found that the annual rate of any antipsychotic use increased nearly 52% to 4.05 per 100 from 2015 to 2024. Long-term use, defined as at least 120 days a year, rose 65% to 2.45 per 100 older adults. Rates were highest among people 75 and older, rising from 3.42 to 5.12 per 100.

The trend is striking because antipsychotics have limited proven effectiveness in people 65 and older and serious risks, including falls, fractures, cardiovascular and cerebrovascular events, pulmonary embolism and death.  Antipsychotics may be used as a last resort to manage severe behavioral and psychological symptoms of dementia, such as aggression, agitation, hallucinations, or delusions, especially when these symptoms pose a risk to the safety of the individual or others.  However, such use carries substantial risk and should be avoided in most cases and limited to short-term use whenever possible.

“The evidence is pretty solid on the risks,” said Stephen Crystal, the letter’s co-author and director of the Center for Health Services Research at the Rutgers Institute for Health, Health Care Policy and Aging Research.

The claims data don’t include diagnoses, so the researchers couldn’t determine why each prescription was written or whether it was appropriate. Antipsychotics remain essential for some people, including those with schizophrenia, bipolar disorder with psychosis or other severe psychiatric illnesses.

However, Crystal noted those conditions aren’t common enough in older populations to explain the surging number of antipsychotic prescriptions.

“We think that conditions like schizophrenia that have FDA-approved indications for antipsychotic treatment are unlikely to account for the majority of the rates of use that we observed,” he said.

The biggest concern for the researchers is using antipsychotics for the behavioral and psychological symptoms that can accompany dementia: agitation, wandering, acting out behavior and shouting. In many cases, the medications are used to “damp down” behaviors that are distressing to caregivers and disruptive to facilities, said Crystal, who also holds endowed professorships at the Institute for Health and Rutgers School of Social Work.

Because the drugs can be highly sedating, they reduce the tendency to roam and act out, but that sedation comes with a steep tradeoff for frail patients, increasing fall risk and reducing physical activity.

The study also reveals a shift in who manages cases. Among patients who took an antipsychotic in a given year, the share with at least one prescription from a psychiatrist fell from 30% in 2015 to 20% in 2024. Over the same period, the share who filled an antipsychotic from a pharmacy in a long-term care facility rose from 14% to 21%.

Crystal said the decline in psychiatrist involvement matters because optimal care for behavioral symptoms in dementia often starts with careful evaluation rather than a quick prescription. Clinicians may need to confirm the diagnosis and look for treatable causes that can mimic or worsen confusion, including medication interactions, infections, depression and unmanaged pain. Even when dementia is the main driver, nondrug approaches can work, but they require training, staffing and time.

“This can look like managing symptoms,” Crystal said. “Which is common because it’s so much easier to write a prescription than do the work of addressing the underlying condition, particularly at nursing home and assisted living facilities that are dangerously short-staffed.”

There was one potentially encouraging sign in the data: the use of first-generation antipsychotics, which are associated with higher mortality risk in older patients than second-generation medications, declined from 22% to 14%.

Still, the overall rise in use and the growth in long-term prescribing suggest a system leaning more heavily on medication to solve problems that are often social, environmental and staffing-related. The authors have called for renewed efforts to evaluate and spread nonpharmacological interventions that can reduce reliance on antipsychotics in older adults.

For families contending with a new prescription, the study’s lead author, Mark Olfson of the Columbia University Department of Psychiatry, said that it is reasonable to ask what problem the drug is meant to address and what other steps have been tried. Just as important is what happens next: whether the clinician has a plan to reassess, taper and stop the medication once a crisis has passed.

“These are high-stakes decisions,” he said.

 

A rare desert plant shows benefits of sustainability efforts at a large solar array in the Mojave Desert



Surveys of threecorner milkvetch at the Gemini Solar Project two years after construction show promising results for advancing renewable energy projects while balancing ecosystem preservation.

The research, published late November in Frontiers in Ecology and Evolution, was led by DRI ecologist Tiffany Pereira. She and her team monitored the Gemini Solar Project for a rare plant called threecorner milkvetch two years after solar panel installation. The results were striking, with 93 plants found on site in 2024 compared to 12 plants found before construction in 2018. This demonstrates that the plant’s seeds not only survived construction, but that the species returned in numbers. By comparing threecorner milkvetch plants at Gemini to those at a nearby site where the habitat was undisturbed, the research is able to relate the differences between the two populations to the solar panel’s impacts, and not just changes in weather patterns.  

“We were curious to see how the seed bank would be impacted by the construction,” Pereira said. “What we found was that not only did the seed bank survive, but the plant came up. And these were big plants, they were larger in every metric we measured — width, height, number of flowers and fruits, leaf length — than the plants that we measured off the site. That was really cool and surprising.”  

The Gemini Solar Project is unique because it made efforts to preserve the desert plants and animals on site during and after construction. Most large-scale solar arrays use a method known as “blade and grade” which involves tearing up the plants and soils before installing the solar panels. This method not only denudes the landscape, it also destroys the fragile seed bank preserved in the top layers of the soil, preventing the habitat from recovering. For these reasons, scientists and conservation practitioners have expressed concerns about the impacts of large solar installations on fragile desert landscapes. Efforts at Gemini show that the push for renewable energy development can be better paired with habitat preservation efforts.  

The plant at the center of the research, threecorner milkvetch, is a rare species in the pea family that is under consideration for listing under the Endangered Species Act. The State of Nevada has categorized it as Critically Endangered and Fully Protected, and the Bureau of Land Management considers it a Special Status Species. Like other plants in this parched part of the world, its persistence is highly dependent on rainfall. As an annual species, it can be impossible to find during dry years and then found in significant numbers when higher rainfall brings the desert back to life. It’s this relationship with water that Pereira and the study team suspect is responsible for the plant’s higher growth rates at Gemini.  

“Subsequent years of monitoring will help us unpack this,” Pereira said, “but the soil moisture content on Gemini is higher after rainfall events. The water is retained in the ground for longer after rainstorms, so it takes longer to dry out. The plants might just be soaking up that extra water.”  

Pereira emphasizes that the results of this study only represent one year of surveys following construction, and that she will continue surveying Gemini for threecorner milkvetch plants to determine if this pattern holds. Her team also noted in the study that although the plants at Gemini seemed to be thriving, they only found one plant growing in the shaded area beneath a solar panel. This could mean that there continue to be tradeoffs in habitat reduction, as the species may now be limited to germinating in the limited space between solar panels. Pereira is planning to conduct a germination study to verify this limitation.  

“Our main goal for land managers is always avoidance,” she said. “When it comes to rare plant habitat, avoid if possible, and then these alternative construction methods can be used to preserve habitat in areas where it can’t be avoided.”  

The study offers hope for powering humanity’s needs with fossil fuel-free, plentiful sunlight, without sacrificing the sweeping desert vistas that are the allure of the Southwest.  

“Our desert species are amazing,” Pereira said. “These seedbanks can withstand a lot — they persist in the soil for years, just waiting for the right conditions to germinate, and now we know that they can even survive through more gentle construction methods. With a little ingenuity, we can address both habitat and renewable energy concerns. These things can work together.”

(MEMPHIS, Tenn. – January 15, 2026) Adolescents with Human Immunodeficiency Virus (HIV) in Botswana, South Africa, Thailand, Uganda and the United States who received the injectable intramuscular antiviral medications cabotegravir and rilpivirine for nearly a year after being switched from daily oral HIV medications, which they had been on most of their life, experienced no major safety concerns, had continued viral suppression and greatly preferred the new treatment method. The findings, published recently in two companion papers in The Lancet HIV, are the latest results from the National Institutes of Health (NIH)-funded International Maternal Pediatric Adolescent AIDS Clinical Trials (IMPAACT) Network clinical trial, which is co-led by investigators at St. Jude Children’s Research Hospital in the United States and the Centre for Infectious Disease Research in Zambia.

 

“This is the first time in their lives these adolescents could formally stop taking daily oral medications for HIV treatment and just get two injections every eight weeks,” said first and corresponding author on one study and co-senior author on the other, Aditya Gaur, MD, St. Jude Department of Infectious Diseases, who co-leads the IMPAACT 2017 study, also referred to as the More Options for Children and Adolescents (MOCHA) study. “After one year, this treatment approach appears safe and is tolerated by and acceptable to adolescents.”

 

All injectable treatment regimen is safe

 

Adolescents with HIV currently take daily oral medications to keep the virus in check. However, taking daily medications, for any chronic disease is not easy and many struggle with medication adherence. Maintaining consistent medication adherence can be challenging, especially for adolescents, underscoring the need for long-lasting injectables.  

 

The published companion papers describing the IMPAACT 2017/MOCHA study constitute the longest and largest described multinational experience to date of this first all-injectable HIV treatment regimen in a diverse group of virologically-suppressed adolescents. Results show that after 48 weeks, there were no safety concerns, and viral loads remained suppressed.

 

“We observed no unexpected safety signals from the first-ever all-injectable combination retroviral regimen in this adolescent population,” Gaur said. “We saw the expected concentrations of each drug known to be effective in adults and continued virological control.”

 

When long-acting injectable antiviral medications emerged as an alternative to daily oral medications, it was a major milestone for prevention and treatment of HIV. This new report from the IMPAACT 2017/MOCHA study assessed the safety, antiviral activity and pharmacokinetics of the first all-injectable HIV treatment regimen of cabotegravir and rilpivirine given intramuscularly once every two months in adolescents with HIV from around the world. This treatment regimen was already approved for adolescents with HIV who are 12 years or older weighing 35 kilograms or more by the US Food and Drug Administration and a growing number of other regulatory agencies from around the world based on prior clinical findings from the IMPAACT 2017/MOCHA study, which the companion papers further support.

 

Finding out what type of treatment adolescents want

 

Learning that the all-injectable antiviral HIV treatment regimen is safe for patients is important, however, the therapy will only be effective if patients are willing to take it. Therefore, led by Elizabeth Lowenthal based at Children’s Hospital of Philadelphia, the researchers assessed how well patients accepted and tolerated the injectable medications. At 48 weeks, 100% of participants reported they would rather get the injectable regimen than the oral medications. In addition, of the 144 participants originally enrolled in the study, the majority (140) continued the treatment through the reported 48-week period, indicating a high level of acceptability.

 

“It is very exciting to enter an era of long-acting medications for HIV,” Gaur said. “Thanks to the contributions of the study participants, their families, site staff, study team and the collaboration between the NIH, ViiV Healthcare and Johnson & Johnson who made this study possible, we can now offer patients more options, such as these injectables, which provide freedom from daily medications and can be tailored based on patients’ preferences.”
