New brain imaging technique can detect early frontotemporal dementia

Combining psychotherapy with low-dose ketamine, a hallucinogenic drug long used as an anesthetic, is a relatively new approach to treating severe depression and post-traumatic stress, especially in populations with high trauma rates such as firefighters, police officers, and military members. Yet evidence of the efficacy and safety of ketamine for treatment of mental health conditions is still evolving, and the market remains widely unregulated.

Iron-deficiency anemia is a common condition marked by tiredness, headaches or ice cravings. But the oral iron supplements used to treat it can leave behind excess iron that causes inflammation and an upset stomach. A new supplement reported in ACS Applied Materials & Interfaces combines iron, prebiotics and probiotics. In trials, the treatment successfully restored blood iron levels in anemic mice without initiating an inflammatory response or throwing off the balance of the gut microbiota.

Doctors often must make critical decisions in minutes, relying on incomplete information. While electronic health records contain vast amounts of patient data, much of it remains difficult to interpret quickly—especially for patients with rare diseases or unusual symptoms.

An estimated 90% of patients receiving home health care have at least one discrepancy between their medication lists and what they're actually taking—making it more likely they will end up in the hospital.

For the first time, scientists can freeze-frame the exact moment an animal makes up their mind and commits to a choice—simply by looking at their brain activity.

Helping children develop a green thumb could have lifelong health benefits, including preventing cancer, according to new work from a University of Alberta public health researcher.

Child maltreatment, which includes abuse and neglect, is one of the most serious public health concerns worldwide. These adversities leave a lasting impact on the emotional well-being, memory, and social development of affected individuals. The problem, however, reaches far beyond its psychological impact, affecting the brain and biological processes through genetic changes, which have remained unclear until now.

HIV remains a major global health issue, affecting nearly 40 million people worldwide. Current treatments, known as antiretroviral therapy (ART), are highly effective at suppressing the virus and preventing illness, but they are not curative and must be taken for life.

Older adults, especially those living with health conditions, who hold positive views about aging are more likely to engage in vigorous physical activity, according to a study led by the University of Surrey.

A new Special Communication published Oct. 13, 2025, in JAMA outlines how the health care sector should responsibly seize the opportunities of AI, including what must change to ensure AI adoption improves patient outcomes, not just efficiency.

A new study of Australians suffering from long COVID found 56% still had persistent symptoms six months after their initial infection, according to experts from The Australian National University (ANU). In most cases, symptoms included fatigue, shortness of breath and coughing.

Researchers from Monash University's Rehabilitation, Aging and Independent Living (RAIL) Research Center and the National Center for Healthy Aging (a partnership between Monash University and Peninsula Health) found that people with dementia were significantly less likely to receive any allied health referral compared with those with stroke or Parkinson's disease.

People with excess body fat who build and keep muscle may be less likely to develop obesity-induced heart, liver, or kidney damage or die early, according to a new study published in The Journal of Clinical Endocrinology & Metabolism.

Lung cancer screening might be the best-kept secret in health care today. Only about 16% of those who are eligible in the U.S. get screened for lung cancer, but a study appearing in NEJM Catalyst provides a roadmap for how health systems can improve those numbers. The study details how the UR Medicine primary care network reached a nearly 72% lung cancer screening rate.

A friend's struggles with arthritis and the finger braces used to manage it inspired research by a Carnegie Mellon University student that could make it easier for patients to follow rehabilitation plans, speed up recovery times and help people manage chronic conditions.

The conditions where you live may influence your brain health and risk for dementia, according to a new study from Wake Forest University School of Medicine.

A groundbreaking study analyzing data from over 5 million older Americans has found that those who migrate within the U.S. have significantly better health outcomes than those who remain in their birth state, offering compelling evidence of a "healthy migrant effect" within U.S. borders.

A new review published in Sleep Medicine Reviews sheds light on the biological mechanisms that may explain why patients with obstructive sleep apnea (OSA) face higher risks for heart disease, diabetes and other age-related conditions.
