Summary: A clinical trial has revealed that Ambroxol, a common cough medicine in Europe, may help slow cognitive decline in people with Parkinson’s disease dementia. The 12-month study found that the drug stabilized psychiatric symptoms, protected against brain damage, and even improved cognition in genetically at-risk participants.Ambroxol boosts an enzyme...
Head Stimulation Boosts Math Skills in Struggling Learners
Summary: New research shows that safe, non-invasive brain stimulation can enhance math learning in young adults with lower natural brain connectivity. Participants who received transcranial random noise stimulation (tRNS) to the dlPFC performed better during math training than those who received placebo treatment or stimulation elsewhere.These improvements were most notable...
Mental Scan Predicts Dementia Risk and Aging Speed in Menopausal
Summary: A new tool developed by researchers can estimate how fast someone is aging by analyzing a single MRI brain scan, predicting chronic disease risk and dementia years before symptoms appear. Unlike traditional “aging clocks,” this model was trained using longitudinal data from the same individuals, eliminating generational biases.The brain-based...
Eating Diary May Trigger Nightmares
Summary: A new study links lactose intolerance and food sensitivities to disrupted sleep and frequent nightmares. Researchers surveyed over 1,000 students and found that those with dairy intolerance reported more vivid and disturbing dreams, likely due to nighttime gastrointestinal discomfort.Women were more likely to report food-related sleep issues, and unhealthy...
AI Facial Analysis Identifies PTSD
Summary: Diagnosing PTSD in children is often hindered by limited communication and emotional awareness, but new research is using AI to bridge that gap. By analyzing facial movements during interviews, researchers created a privacy-preserving tool that can identify PTSD-related expression patterns.Their system does not use raw video but instead tracks...
Head Stimulation Reverses Neural Damage in Alzheimer’s
Summary: New research shows that low-intensity repetitive transcranial magnetic stimulation (rTMS) can restore key synaptic structures in mouse models of Alzheimer’s disease. The study found that axonal boutons—sites where neurons form connections—had reduced turnover in Alzheimer’s mice, indicating impaired brain plasticity.After a single rTMS session, the turnover of one bouton...
The Left-Handed Creativity Myth Is Discredited
Summary: The long-standing belief that left-handed people are more creative has been challenged by a new meta-analysis of over a century of research. After reviewing nearly 1,000 studies, researchers found no consistent advantage in creative thinking for lefties—in fact, right-handers slightly outperformed on some tests.Left-handed individuals are overrepresented in fields...
Small RNA Marks Aid in Explaining Mental Disorders and Brain Wiring
Summary: New research reveals how a tiny chemical mark on RNA helps wire the brain during development. Scientists discovered that m6A methylation regulates the production of proteins essential for axon growth, including APC and β-actin.This precise control supports the formation of neural circuits, and its disruption has been linked to...
Through music, the brain tracks mental moves.
Summary: New research reveals how the brain navigates emotional transitions, using music as a tool to map changing neural patterns. Scientists found that emotional responses in the brain depend heavily on the listener’s prior emotional state.For instance, hearing a happy tune before a sad one changes the way the brain...
Also When AI Says the Same Thing, People Prefer Human Empathy.
Summary: A new study shows that people rate empathic responses as more supportive and emotionally satisfying when they believe they come from a human—even if the same response is AI-generated. Across nine experiments with over 6,000 participants, responses labeled as human were consistently seen as more genuine, especially when they...
