Scientists have identified a “switch” in the brain that can turn off chronic pain, by activating special neurons, the brain’s survival priorities like hunger and fear can override pain signals. This could lead to new treatments that block pain at its source, offering hope for those with persistent pain.

Scientists discover brain circuit that can switch off chronic pain | ScienceDaily

Scientists have pinpointed Y1 receptor neurons in the brain that can override chronic pain signals when survival instincts like hunger or fear take precedence. Acting like a neural switchboard, these cells balance pain with other biological needs. The research could pave the way for personalized tre...

New evidence suggests tiny plastic particles might be silently reshaping brain health. A new review highlighted in ScienceAlert found microplastics lodged in cerebral blood vessels of dementia patients, particularly those with vascular dementia. These pollutants may worsen microbleeds and vascular blockages, increasing risk for cognitive decline. Researchers warn that environmental toxins—long linked to heart and endocrine issues—could also be driving neurodegeneration.Protecting brain health may now mean reducing plastic exposure as much as possible.


Microplastics May Be Tied to Vascular Dementia Cases, Review Finds : ScienceAlert

Vascular dementia is caused by blood flow issues in the brain: it's one of the most common types of dementia, but not as well researched or understood as others.

Parkinson’s disease is best known for its impact on movement—tremors, stiffness, and slowed motion. But many people living with the condition also experience cognitive problems such as poor concentration and forgetfulness. Over time, these symptoms can progress to dementia, which is often one of...

New research from the University of Missouri reveals how a high-fat ketogenic diet may help preserve brain energy and delay cognitive decline—especially in women carrying the APOE4 gene, the top genetic risk factor for Alzheimer’s. The study found that ketones, produced during ketosis, can serve as an alternative fuel for the brain when glucose metabolism falters, leading to healthier brain cells and gut microbiota. This emerging field of precision nutrition may transform how we approach brain aging prevention decades before symptoms appear.

Mizzou scientists are exploring how a ketogenic diet may protect the brain and prevent Alzheimer’s in people genetically predisposed to it. Their study found that female mice with the APOE4 gene benefited most, showing improved gut and brain health on a high-fat, low-carb diet. The findings highli...

Neurocognitive Exams & Dementia Staging
Neurocognitive exams are essential for detecting dementia early, determining the stage, and guiding the right care for each individual. These exams provide the roadmap needed for tailored support, offering clarity for families, patients, and providers at every step of the dementia journey. Social media empowers communities by raising awareness, sharing evidence-based education, connecting caregivers, and reducing stigma—ensuring no one faces dementia alone. Let’s champion early testing and informed care for a brighter, more supported future!

Recent insights reveal that Alzheimer’s disease may not just be a “brain disease.” Cutting-edge research suggests it’s fundamentally linked to the brain’s immune system—possibly an autoimmune process—making brain health broader and more complex than we once believed. These new findings could transform how we understand, prevent, and treat cognitive decline.Your brain health is vital, and early cognitive checkups are essential for proactive care. A neuropsychological assessment can offer valuable answers for memory, attention, and overall brain function. Don’t wait—prioritize your cognitive wellness and schedule a checkup today!
