(Press-News.org) MINNEAPOLIS — A new study found that Native Hawaiian or Pacific Islander people had the highest rate of stroke among people from other race and ethnic groups, with a rate more than three times higher than that of white people. The study is published on August 27, 2025, in Neurology®, the medical journal of the American Academy of Neurology.
“Multiple studies have shown racial and ethnic disparities in the rate of stroke in the United States, but there is little information on the rate among Native Hawaiian or Pacific Islander people, especially among those living in the contiguous US mainland,” said study author Fadar O. Otite, MD, MS, of the State University of New York Upstate Medical University in Syracuse and a member of the American Academy of Neurology. “Since Native Hawaiian or Pacific Islander people are among the fastest growing populations in the US and have one of the highest rates of death from cardiovascular disease, we wanted to focus on the risk among this group.”
Researchers examined databases from Florida, Georgia, Maryland and New York for cases of ischemic stroke during a period of up to six years. Ischemic stroke, the most common type of stroke, is when blood flow is blocked to part of the brain.
The stroke cases were combined with Census data from each state on the number of white, Black, Hispanic, Asian, and Native Hawaiian or Pacific Islander people to determine the rate of stroke.
There were 799,150 cases of stroke during the study. After adjusting for age and sex, researchers found the stroke rate for Native Hawaiian or Pacific Islander people was 591 cases for 100,000 people, compared to 292 cases for Black people, 180 cases for white people, 145 cases for Hispanic people and 108 cases for Asian people.
After researchers adjusted further for year of hospitalization to account for advances in stroke care, they found that the stroke rate was 3.3 times higher among Native Hawaiian or Pacific Islander people than among white people, almost four times higher than among Hispanic people and more than five times higher than among Asian people. Native Hawaiian or Pacific Islander people had a lower rate of stroke than Black people in Florida, but a higher rate in Georgia, Maryland and New York.
“More research is needed into the reasons for this disparity so that it can be tackled appropriately,” Otite said. “These findings also lend support to the need for parsing out information on race and ethnicity in health care databases, where Asian people and Native Hawaiian or Pacific Islander people are usually combined into one large group.”
A limitation of the study was that only strokes where the person was taken to the hospital were captured, so the total number of cases would be higher if people who never went to the hospital were included.

Scientists reveal warped protoplanetary discs, reshaping ideas about how planets form
2025-08-27
The textbook picture of how planets form – serene, flat discs of cosmic dust – has just received a significant cosmic twist. New research, published in the Astrophysical Journal Letters, is set to reshape this long-held view. An international team of scientists, wielding the formidable power of the Atacama Large Millimetre/submillimetre Array (ALMA), has found compelling evidence that many protoplanetary discs, the very birthplaces of planets, are in fact subtly warped.
These slight bends and twists in the disc plane, often just a few ...
Be it feast or famine, orangutans adapt with flexible diets
2025-08-27
Humans could learn a thing or two from orangutans when it comes to maintaining a balanced, protein-filled diet.
Great apes native to the rainforests of Indonesia and Malaysia, orangutans are marvels of adaptation to the vagaries of food supply in the wild, according to an international team of researchers led by a Rutgers University-New Brunswick scientist. The critically endangered primates outshine modern humans in avoiding obesity through their balanced choices of food and exercise, the scientists found.
The researchers reported their findings, based on 15 years of firsthand observations of wild orangutans ...
Insomnia patients report better sleep when taking cannabis-based medical products
2025-08-27
Insomnia patients taking cannabis-based medical products reported better quality sleep after up to 18 months of treatment, according to a study published August 27 in the open-access journal PLOS Mental Health by Arushika Aggarwal from Imperial College London, U.K., and colleagues.
About one out of every three people has some trouble getting a good night’s rest, and 10 percent of adults meet the criteria for an insomnia disorder. But current treatments can be difficult to obtain, and the drugs approved for insomnia run the risk ...

New crocodile-relative “hypercarnivore” from prehistoric Patagonia was 11.5ft long and weighed 250kg
2025-08-27
A newly-discovered species of a large, crocodile-relative predator has been described via a remarkably well-preserved fossil from Argentina, according to a study published August 27, 2025, in the open-access journal PLOS One by Fernando Novas from Museo Argentino de Ciencias Naturales “Bernardino Rivadavia”, Argentina, and colleagues.
The Chorrillo Formation formed around 70 million years ago, during the Maastrichtian age at the very end of the Cretaceous period. At this time, southern Patagonia was a warm, seasonally humid landscape of freshwater floodplains, home to creatures like dinosaurs, turtles, frogs, and various mammals.
The new fossil unearthed in this formation is ...
“Unhappiness hump” in aging may have disappeared worldwide
2025-08-27
A new survey-based study suggests that the “unhappiness hump”—a widely documented rise in worry, stress, and depression with age that peaks in midlife and then declines—may have disappeared, perhaps due to declining mental health among younger people. David Blanchflower of Dartmouth College, U.S., and colleagues present these findings in the open-access journal PLOS One on August 27, 2025.
Since 2008, a U-shaped trend in wellbeing with age, in which wellbeing tends to decline from childhood until around age 50 before ...
Breathwork can induce altered states of consciousness linked with changes in brain blood flow
2025-08-27
Breathwork while listening to music may induce a blissful state in practitioners, accompanied by changes in blood flow to emotion-processing brain regions, according to a study published August 27, 2025, in the open-access journal PLOS One by Amy Amla Kartar from the Colasanti Lab in the Department of Clinical Neuroscience at Brighton and Sussex Medical School, U.K., and colleagues. These changes occur even while the body’s stress response may be activated and are associated with reporting reduced negative ...
New research makes first broad-spectrum antiviral
2025-08-27
NEW YORK, August 27, 2025 — Researchers at the Nanoscience Initiative at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) have made a breakthrough in the fight against viral diseases. Their study, published in the journal Science Advances, offers a promising path toward the development of the world’s first broad-spectrum antiviral (BSA), which could be deployed against a wide range of deadly viruses, including future pandemic threats.
Unlike bacterial infections, which doctors often begin immediately treating with broad-spectrum antibiotics while they work to determine the specific bacteria, viral infections ...
Good sleep quality might be key for better mental wellbeing in young adults
2025-08-27
A new study of young adults has strongly linked better sleep quality with better mental wellbeing, with fruit and vegetable consumption and physical activity also strongly associated with psychological wellbeing. Perhaps surprisingly, the findings also suggest that boosting fruit and vegetable intake could potentially help mitigate the effects on wellbeing of a poor night’s sleep. Dr. Jack Cooper, previously from the University of Otago, New Zealand, and colleagues present these findings in the open-access journal PLOS One on August 27, 2025.

One step closer to improving ER+ breast cancer patients’ response to therapy
2025-08-27
A new study from researchers at Baylor College of Medicine brings hope for a more personalized approach to treat estrogen receptor-positive (ER+) breast cancer, the most common type of this cancer. The team identified a biomarker in preclinical ER+ breast cancer models that indicates that the tumor is more likely to respond to treatment with CDK4/6 inhibitors. The findings support further clinical studies to determine whether this marker may help identify patients who could benefit from CDK4/6 inhibitors. The study appeared in Science Translational Medicine.
ER+ breast ...
