Aging brain biology actively shapes brain tumor progression, treatment resistance, and cognitive decline, according to a review published in Ageing and Cancer Research & Treatment. Rather than viewing aging as a passive background variable, the study—titled “Navigating the aging brain: The interplay between brain malignancy and the aging microenvironment”—proposes that the physiological shifts of an … Read more
Efforts to prevent dementia are placing too much responsibility on individual choices while overlooking broader social, environmental, and policy conditions that shape lifelong brain health, according to Curtin University research published in The Lancet Public Health. Researchers mapped 61 potentially modifiable risk and protective factors, revealing an overemphasis on individual behavior change despite many risks … Read more
Microcatheters used to deliver targeted therapies into the brain, retina, or inner ear face a persistent risk of failure when a single cough, deep breath, or postural shift forces blood and tissue backward into the channel. According to a study published in the International Journal of Extreme Manufacturing by Prof. Zhuo-Chen Ma, Prof. Bing Han … Read more
Millions of patients taking glucagon-like peptide-1 receptor agonists (GLP-1RAs) for type 2 diabetes and obesity face renewed clarity regarding psychiatric safety, according to a systematic review published in the journal Cureus by Quadir et al. Researchers evaluating 11 primary studies representing over 4.9 million patients found no consistent class-wide increase in neuropsychiatric risks such as … Read more
According to a theoretical paper published by neuroscientists Earl K. Miller, Scott L. Brincat, and Jefferson E. Roy in The Journal of Neuroscience, the brain manages fast and flexible cognition not solely through fixed synaptic pathways, but through rhythmic electrical waves acting as an organizing signal across the cortical surface. This spatiotemporal computing framework suggests … Read more
Adolescent binge drinking causes lasting disruptions in communication between supportive brain cells and synapses in the hippocampus, according to new research published August 15 in Molecular Psychiatry. Edwards School of Medicine found that these structural and functional changes persist into adulthood even after prolonged periods of abstinence, potentially altering fear-related behavior. How Adolescent Intermittent Ethanol … Read more
According to a joint practice guideline update issued on August 31, 2026, by the American Academy of Neurology and the American Headache Society, clinicians now have revised, evidence-based recommendations to determine the most effective preventive medications for adult migraine patients. Published in the medical journals Neurology and Headache, the updated guidance supersedes the previous 2012 … Read more
Recent findings from a large UK Biobank analysis published in the journal Alzheimer’s & Dementia indicate that hormone replacement therapy use is associated with a modest 10% reduction in all-cause dementia risk among postmenopausal women, though the effect varies significantly depending on menopause type, estrogen exposure duration, and the timing of treatment initiation. UK Biobank … Read more
Researchers at the Mass General Brigham Neuroscience Institute have discovered that a specific pattern of brain shrinkage visible on MRI scans can help predict how quickly individuals with early-onset Alzheimer’s disease progress from mild cognitive impairment to dementia, according to findings published in the journal Neurology. MRI Brain Atrophy Predicts Early-Onset Alzheimer’s Progression Early-onset Alzheimer’s … Read more
According to a study published in the journal Nature Medicine, age-related cognitive decline in humans is linked to the dysfunction of oligodendrocytes, the brain cells responsible for forming myelin. Researchers from the University of Edinburgh and the UK Dementia Research Institute analyzed brain tissue from participants in the Lothian Birth Cohort 1936 to track how … Read more
