Almost half of dementia cases could be prevented—but change is needed
Almost half of dementia cases could be prevented—but change is needed
Nearly half of dementia cases could be prevented by tackling modifiable risk factors such as physical inactivity, smoking, low education or social isolation, but new Curtin University research suggests current public health approaches are falling short in driving real behavior ch
What is mild cognitive impairment? And does it always lead to dementia?
What is mild cognitive impairment? And does it always lead to dementia?
You've forgotten a few appointments lately, and you find yourself losing track of conversations. Close friends or family may have also noticed some changes in your memory or thinking.
Common brain cancer mutation changes DNA shape to drive progression, exposing therapeutic
Common brain cancer mutation changes DNA shape to drive progression, exposing therapeutic
A new study from researchers at The University of Texas MD Anderson Cancer Center has uncovered how one of the most common genetic alterations in glioma rewires the cancer cell genome to fuel tumor progression, suggesting a potential new therapeutic strategy for patients with ATR
Uterine aging linked to poorer pregnancy outcomes after 49 despite donor eggs
A major new study suggests that age-related changes in the uterus may contribute to poorer pregnancy outcomes, with women aged 49 and older experiencing lower live birth rates and higher miscarriage risk despite donor-oocyte treatment. Presented at the 42nd Annual Meeting of the
PET scans reveal stage-linked tau signal in Huntington's disease brains
A study conducted by the Sant Pau Research Institute (IR Sant Pau) and Hospital de Sant Pau has identified for the first time in living individuals a brain pattern related to the tau protein that changes according to the stage of Huntington's disease. This discovery opens the doo
Pregnancy recruits killer T cells that may guard breasts against cancer for years
An Australian study by researchers at Peter Mac has shown that the natural protection against breast cancer offered by childbearing is due to the influx of killer T cells to the breast. The research shows that the cells begin to populate the breast during pregnancy and are closel
Just one exposure to cocaine alters mouse brain cells for 2 weeks, research reveals
Researchers studying the impact of cocaine in mice have found that just one exposure to the drug can create changes in brain cells that persist for at least two weeks. Their findings were presented at the Federation of European Neuroscience Societies (FENS) Forum 2026.
Study linking microgravity and space radiation to accelerated aging could yield therapies
Study linking microgravity and space radiation to accelerated aging could yield therapies
What happens to the human body in space may help scientists create new anti-aging therapies. UCF's Michal Masternak and his team have identified molecular changes in the liver that happen when space travelers experience radiation and microgravity. These changes—that resemble acce
Why does Parkinson's disease affect more men than women?
Why does Parkinson's disease affect more men than women?
New research presented at the Federation of European Neuroscience Societies (FENS) Forum 2026 has discovered some of the genetic changes in brain cells that may help explain why more men than women develop Parkinson's disease.
New comprehensive data platform could transform Alzheimer's research, treatment
With an increasingly aging global population and no available preventive treatments, Alzheimer's disease and related dementias are poised to become an even larger public health challenge. The mechanisms underlying Alzheimer's disease are difficult to study because the disease has
Alcohol drives opposite brain circuit changes in amyloid and tau Alzheimer's models
Alcohol use has been associated with an increased risk of cognitive decline and dementia. But new research from Texas A&M University's Naresh K. Vashisht College of Medicine at Texas A&M Health suggests the relationship between alcohol and Alzheimer's disease is more complicated
Psychedelic drug screen in mice may overlook stress and brain changes
Over the past decades, some medical researchers and neuroscientists have been exploring the possible therapeutic effects of psychedelic compounds, such as lysergic acid diethylamide (LSD) and psilocybin. These are substances that act on serotonin receptors in the brain and can al
