(Press-News.org) More than three-quarters of older adults with dementia may be unaware of their diagnosis, a University of Michigan study finds.
That number is even higher — up to 85% — among Mexican Americans, who make up the largest share of the U.S. Hispanic and Latino population.
Fewer than 7% of all study participants, who live in Nueces County, Texas and were classified as having probable dementia based on a cognitive assessment, did not have a primary care provider.
The results are published in the Journal of General Internal Medicine.
“Dementia diagnosis unawareness is a public health issue that must be addressed,” said senior author Lewis Morgenstern, M.D., professor of neurology, neurosurgery and emergency medicine at University of Michigan Medical School and professor of epidemiology at the U-M School of Public Health.
“The diagnosis of dementia provides the opportunity to seek out treatment and home care services to help both patients and caregivers. If the diagnosis is not given, or the understanding of the diagnosis is unclear, it is a missed opportunity.”
Investigators found no link between access to primary care and awareness of dementia diagnosis. In other words, they weren't in the dark about their diagnosis for lack of communication with their doctor.
In fact, researchers suspect that the nature of patient-physician relationships is a central reason the awareness gap.
“The physician may not be diagnosing the patient or may be withholding the diagnosis of dementia,” said first author Josh Martins-Caulfield, a graduate of the U-M School of Public Health and medical student at the Icahn School of Medicine at Mount Sinai.
“In practice, physicians often hesitate to diagnose dementia, citing reasons such as insufficient time with individual patients to conduct the screening process or not having dementia-specific training. The discomfort of providing the diagnosis may also lead them to wait for patients or family members to raise concerns about memory issues rather than initiating discussions proactively.”
Several studies have found that the majority of older adults in the U.S. with probable dementia go either undiagnosed or are unaware of a diagnosis. One 2018 report revealed that Hispanic and Latino adults were more likely to be undiagnosed.
“Cultural competence is crucial in treating all patients, especially when dealing with a heavily stigmatized disease,” Morgenstern said.
Despite the lack of dementia awareness found in the study, having a formal diagnosis did not reduce a caregiver’s perceived burden.
This could be, researchers suggest, because the diagnosis forces caregivers to quickly confront the increased responsibilities that come with the diagnosis of dementia in a loved one, including decision making and managing daily care.
“Caregiving can be immensely taxing, particularly when balancing one’s own family responsibilities and personal life,” said Darin B. Zahuranec, M.D., M.S., co-author and a professor of neurology at U-M Medical School.
“Effective care necessitates accurate diagnosis combined with comprehensive emotional support and guidance for caregivers to access essential resources.”

Study reveals root-lesion nematodes in maize crops - and one potential new species
2025-01-14
A new study has lifted the lid on five species of root-lesion nematodes living in maize crops across New Zealand - and suggested the existence of a hitherto-unsuspected cryptic species.
The article, ‘Molecular characterization of root-lesion nematode, (Pratylenchus spp.) and their prevalence in New Zealand maize fields’, is published in Letters in Applied Microbiology, an Applied Microbiology International publication.
Identifying these nematodes and understanding their distribution will enable targeted pest management strategies, helping to protect crop yields and maintain agricultural ...
Bioinspired weather-responsive adaptive shading
2025-01-14
Pine cones as a model: Researchers at the universities of Stuttgart and Freiburg have developed a new, energy-autonomous facade system that adapts passively to the weather. The journal Nature Communications has published the research results.
"Most attempts at weather responsiveness in architectural facades rely heavily on elaborate technical devices. Our research explores how we can harness the responsiveness of the material itself through advanced computational design and additive manufacturing," says Professor Achim Menges, head of the Institute for Computational Design and Construction ...

Researchers uncover what drives aggressive bone cancer
Large-scale analysis of patient cohorts reveals a novel mechanism driving osteosarcoma, an aggressive paediatric bone cancer.
The researchers show that this mechanism occurs in approximately 50% of high-grade osteosarcoma cases.
This research also provides insights to help predict osteosarcoma patient outcomes which can help improve the management of this disease.
Osteosarcoma is a type of aggressive bone cancer that most commonly affects children and young adults between the ages of 10 and 20, during times ...
Just as Gouda: Improving the quality of cheese alternatives
2025-01-14
WASHINGTON, Jan. 14, 2025 – Plant-based dairy products are a great alternative for people who avoid animal products, but manufacturers have a hard time replicating the creamy, cheesy qualities that make dairy so indulgent.
Scientists from the University of Guelph in Ontario and Canadian Light Source Inc. in Saskatchewan are working to produce plant-based cheese with all the characteristics of real cheese, but with better health benefits.
In Physics of Fluids, by AIP Publishing, researchers studied multiple types of plant-based proteins and how they interact with ...
Digital meditation to target employee stress

Electronic patient-reported outcome system implementation in outpatient cardiovascular care
2025-01-14
About The Study: In this randomized clinical trial, implementation of the electronic patient-reported outcome (ePRO) monitoring system significantly enhanced patient-physician communication and the clarity of physicians’ explanations about treatment. These findings suggest that the ePRO monitoring system is capable of supporting patient-centered cardiovascular care.

Knowledge and use of menthol-mimicking cigarettes among adults in the US
2025-01-14
About The Study: In this survey study of U.S. adults, a substantial proportion were aware of and had already experimented with synthetic cooling agent menthol-mimicking cigarettes. These products may serve as a substitute for menthol cigarettes and reduce the public health benefits of a menthol cigarette ban in promoting smoking cessation.

Uncurling a single DNA molecule and gluing it down helps sharpen images
2025-01-14
WASHINGTON, Jan. 14, 2025 – Most microscopes can only illuminate objects down to a certain size before tiny features blur together. This blurring is known as the diffraction limit of light. Super-resolution imaging techniques, however, can distinguish between tiny biomolecular features, especially when thermal fluctuations are minimized.
Using advanced imaging techniques and precise microfluidics control to stretch out curly DNA into a straight line, research published this week in AIP Advances, from AIP Publishing, demonstrates ...
Medicare Advantage beneficiaries did not receive more dental, vision or hearing care
2025-01-14
As the privatized form of Medicare, Medicare Advantage plans advertise dental, vision, and hearing benefits not covered by traditional Medicare, but a recent analysis found that Medicare Advantage beneficiaries do not typically receive more of these supplemental services than traditional Medicare beneficiaries. Additionally, out-of-pocket spending was similar for most supplemental services. The research led by a team from Mass General Brigham is published in JAMA Network Open.
“Medicare Advantage plans receive more money per beneficiary than traditional Medicare plans, but our findings add to the evidence that this increased cost is not justified,” said first author Christopher ...
Green hydrogen: Big gaps between ambition and implementation
2025-01-14
"Over the past three years, global project announcements for green hydrogen have almost tripled," says PIK researcher and lead author Adrian Odenweller. "However, only seven percent of the production capacity originally announced for 2023 has been completed on time during this period." According to the study, the recent problems with the market ramp-up of green hydrogen can be attributed to increased costs, a lack of willingness to pay on the demand side and uncertainties about future subsidies and regulation.
"Enormous additional subsidies of around one trillion US dollars would be required to realise all announced hydrogen projects by 2030," explains Falko ...
