TL;DR: A new study reveals that impaired cerebrovascular function—the brain’s ability to regulate blood flow—correlates strongly with Alzheimer’s symptoms, offering a potential non-invasive way to detect early cognitive decline. Alzheimer’s disease has long been framed as a problem of toxic protein accumulation: amyloid plaques and tau tangles strangling neurons into silence. But what if the …
TL;DR: Researchers discovered a toxic interaction between two brain proteins—NMDAR and TRPM4—that drives neurodegeneration in Alzheimer’s disease, and a small molecule called FP802 that blocks this “death complex” and prevents cognitive decline in mice. Alzheimer’s disease devastates the brain through multiple pathways, but the exact triggering mechanisms remain frustratingly unclear. A new study in Molecular …
TL;DR: The brain stores content (what you remember) and context (when/where) in separate neural populations linked by real-time coordination, not pre-wired conjunctive cells—a design that trades speed for flexibility, allowing you to recognize a friend’s face across any setting or apply a principle learned once to infinitely new situations. For forty years, neuroscientists thought memory …
TL;DR: A psychedelic drug that activates serotonin receptors dramatically amplifies slow 5-Hz brain oscillations in visual and memory regions, suggesting a mechanism for how hallucinogens distort perception by letting internal signals override external reality. Visual perception feels stable, seamless, continuous. But that stability is an illusion orchestrated by your brain. What neuroscientists have long wondered …
TL;DR: A new blood test using three misfolded plasma proteins can identify Alzheimer’s disease with 83.44% accuracy, outperforming conventional biomarkers and offering a non-invasive screening tool years before cognitive symptoms appear. The holy grail of Alzheimer’s research isn’t a cure—yet. It’s catching the disease before memory starts to fade. By the time someone notices confusion, …
Video game addiction (VGA) is associated with significant deficits in response inhibition and preparatory processes, reflected by more commission errors and reduced N2 amplitudes in the cued Go/NoGo task. Highlights: Increased Commission Errors: Individuals with VGA made significantly more commission errors in NoGo trials compared to healthy controls, indicating impaired response inhibition. Faster Reaction Times: …
Omega-3 supplements and Souvenaid® show potential in slowing cognitive decline in Alzheimer’s patients, though the evidence remains inconclusive. Highlights: Cognitive Decline Reduction: The CDR scale showed a significant reduction in cognitive decline progression with Omega-3 supplementation (SMD = −0.4127, 95% CI: [−0.5926; −0.2327]). Mixed Cognitive Outcomes: 58% of studies reported positive cognitive effects from Omega-3 …
Guanfacine extended release (GXR) may effectively improve cognitive impairments and brain activity in long-COVID patients. Highlights: Patient Presentation: A 32-year-old woman experienced cognitive impairments such as difficulty in word recall, reading, and writing, and delayed task completion following COVID-19 infection. Baseline Assessment: Initial tests showed poor performance in attention, working memory, and executive function, with …
ACOT7 shows promise as a non-invasive serum biomarker for Alzheimer’s disease (AD) with high diagnostic accuracy. Highlights: Increased Expression: ACOT7 levels were significantly elevated in AD patients and animal models compared to controls. Correlation with Cognitive Decline: A strong negative correlation was observed between serum ACOT7 levels and MMSE scores (r = -0.85; p < …
Elevated blood urea nitrogen and creatinine ratio (BUNCr) is associated with decreased cognitive function and increased depressive symptoms, with depressive symptoms mediating part of the relationship between BUNCr and cognitive decline. Highlights: BUNCr has a negative association with cognitive function, with higher BUNCr levels linked to lower cognitive performance. BUNCr is positively associated with depressive …
