  • New research finds changing your diet could ease persistent headaches after brain injury (Omega-3 vs. Omega-6 fats)

    A new clinical trial demonstrates that dietary changes significantly reduce persistent post-traumatic headaches (pPTH), a common and debilitating consequence of traumatic brain injury (TBI). Researchers found that increasing omega-3 fatty acids (commonly found in fatty fish like salmon and tuna) while reducing omega-6 fatty acids (abundant in seed oils such as corn, sunflower, and cottonseed oils) led to fewer and less severe headaches. The randomized trial involved 122 military health care beneficiaries suffering from chronic headaches following TBI. In addition to their current headache treatments, patients were asked to adhere to one of two diets for 12 weeks: a control...

    So I just got back from a neurologist for a little more of a precise diagnosis of what for a couple of decades has been called "ADHD." It was actually a very in-depth series of IQ tests. Turns out I'm "genius" level in comprehension, verbal abilities, short-term memory, and so on. But seriously below average in long-term memory. Like 145, 143, 141, 139, 147, 151... 86??? Fortunately, it doesn't fit any profiles of dementia or Alzheimer's, especially since I'd be incredibly young for that. Could be brain damage, given my history. Could just be a weird roll of the dice,...

    New research has found that being overworked can physically alter the brain. Researchers in South Korea set out to understand how working long hours impact the cognitive and emotional health of employees. The study, published in the journal Occupational & Environmental Medicine, assessed the brain volume of 110 healthcare workers who were classified by the categories of overworked — working greater than or equal to 52 hours per week — and non-overworked. […] The increased brain volume as observed was found in regions associated with executive functions, (study co-author Wanhyung) Lee said, such as memory, decision-making and attention — as...

    The internet is abuzz with tributes to a liquid chemical called methylene blue that is being sold as a health supplement. Over the past five or 10 years, methylene blue has come to be touted online as a so-called nootropic agent – a substance that enhances cognitive function. Vendors claim that it amps up brain energy, improves memory, boosts focus and dispels brain fog, among other supposed benefits. Health influencers, such as podcaster Joe Rogan, have sung its praises. In February 2025, shortly before he was confirmed as health and human services secretary, Robert F. Kennedy Jr. appeared in a...

    ChatGPT was released two and a half years ago, and we have been in a public panic ever since. Artificial intelligence can write in a way that passes for human, creating a fear that relying too heavily on machine-generated text will diminish our ability to read and write at a high level. We’ve heard that the college essay is dead, and that alarming number of students use A.I. tools to cheat their way through college. This has the potential to undermine the future of jobs, education and art all at once.The Titanic is indeed headed toward the iceberg, but the...
  • Brain inflammation linked to repetitive behaviors in autism and obsessive-compulsive disorder (Namenda)

    A research team has unveiled the cause and molecular mechanism of chronic brain inflammation that results in repetitive behavioral disorders. The research team demonstrated that an inflammatory response by immune cells in the brain induces overactivity in certain receptors, which may, in turn, lead to the meaningless repetitive behaviors observed in people with autism spectrum disorder (ASD) and obsessive-compulsive disorder (OCD). The research involved mice with a mutated NLRP3 gene. This gene mutation stimulates a chronic inflammatory response by immune cells in the brain that are called microglia. Prolonged inflammation overactivates N-methyl-D-aspartate (NMDA) glutamate receptors, which are important for excitatory...

    A common sleep aid restores healthier sleep patterns and protects mice from the brain damage seen in neurodegenerative disorders, such as Alzheimer's disease, according to new research. The drug, lemborexant, prevents the harmful buildup of an abnormal form of a protein called tau in the brain, reducing the inflammatory brain damage tau is known to cause in Alzheimer's. The study suggests that lemborexant could help treat or prevent the damage caused by tau in multiple neurodegenerative diseases, including Alzheimer's, progressive supranuclear palsy, corticobasal syndrome and some frontotemporal dementias. "In this new study, we have shown that lemborexant improves sleep and...

    Buried for hundreds of years, ancient brains are finally speaking. What they’re saying could change everything we thought we knew. A pioneering scientific breakthrough has made it possible to extract proteins from preserved soft tissues, including human brains, revealing a vast archive of biological information that has long remained inaccessible. This new method promises to reshape our understanding of evolution, diet, microbiomes, and even the development of brain cells over millennia. Tapping Into Hidden Biological Archives Every organism is built from proteins—molecules that drive vital processes such as heartbeats and neural communication. When an organism dies, these proteins usually degrade...

    The implications of this research could redefine the boundary between life and death. ================================================================= About five years ago, Yale School of Medicine neuroscientist Zvonimir Vrselja, Ph.D., and his colleagues shocked the medical community with a groundbreaking experiment. They removed a slaughterhouse pig’s brain from its head and deprived it of oxygen at room temperature for four hours. Then, they hooked it up to their resuscitation machine and revived it—to an extent. A living brain’s vasculature, or network of blood vessels, carries oxygenated, nutrient-rich blood to the brain through arteries and capillaries. So, the researchers used their machine, called BrainEx, to...

    Reducing high blood pressure substantially lowers the risk of dementia and cognitive impairment without dementia, according to the results of a phase 3 clinical trial involving almost 34,000 patients. These findings highlight the potential importance of widespread adoption of more intensive blood pressure control among patients with hypertension to reduce the global disease burden of dementia. Research has found that people with untreated hypertension have a 42% greater risk of developing dementia in their lifetime than healthy study participants. Jiang He and colleagues tested the effectiveness of an intervention led by non-physician community health care providers (sometimes called "village doctors")...

    A new study is shedding light on how insufficient consumption of vitamin K may adversely affect cognition as people get older. The study suggests that a lack of vitamin K may increase inflammation and hamper proliferation of neural cells in the hippocampus, a portion of the brain that is capable of generating new cells and is central to functions such as learning and memory. Vitamin K is found in green leafy vegetables such as Brussels sprouts, broccoli, green peas, kale, and spinach. In the new research, researchers conducted a six-month dietary intervention to compare the cognitive performance of mice that...

    People’s political affiliation can be shown in their brain activity when they carry out mundane chores such as buying food, a new study shows. How the brain reacts to food purchasing decisions can be used to determine people’s political affiliation with almost 80 per cent accuracy, researchers have found. Although buying eggs and milk can lack emotional potency and political content, understanding how the neural systems lead people to make indistinguishable choices may help to explain the broader mechanisms of partisanship.Experts from Iowa State University, the University of Kansas Medical Center, Oklahoma State University, and the University of Exeter measured...

    Scientists have long recognized the brain's need for energy, but new research has now illuminated how the brain's energy utilization significantly influences our sleep patterns. The team discovered certain channels in the brain, called ATP-sensitive potassium (KATP) channels, act as energy sensors and play a pivotal role in maintaining stable sleep-wake cycles and facilitating smooth transitions between cycles. "Our study shows that even small changes in energy usage can profoundly impact behavior," said Macauley. These changes impact when we sleep, how we sleep and the overall quality of our sleep. The study identified a previously unknown function of KATP channels...

    A research team is testing a new combination drug therapy that could both treat and prevent melanoma metastasis to the brain. Holmen first examined what causes melanoma cells to spread to the brain and identified focal adhesion kinase (FAK) as a potential target for new therapies. FAK is an enzyme that regulates cell growth, and, they found, is a major contributor to melanoma metastasis. "The window of time to treat a patient with brain metastasis is shortened because the average survival from time of diagnosis of brain metastasis is only about a year—even while using these other therapies." Holmen and...

    In a new study, scientists analyzed MRI data stored at the UK Biobank and identified seven genes responsible for fast biological brain aging and 13 existing drugs that can target those genes. Slowing the aging process is a powerful strategy to prevent many diseases and enhance longevity. A crucial parameter in brain health research is the brain age gap (BAG), which is the difference between a person's estimated biological brain age and their chronological age. The brain age gap is also a reliable biomarker (or proxy) for studying brain health. While the effects of the BAG are well explored, identifying...
