Genetics Plus Heart Health Markers Sharpen Dementia Risk

New research shows that dementia risk is best predicted by combining genetic vulnerability with cardiovascular disease markers, revealing a more precise and actionable way to identify who is most likely to develop the condition. While genes such as APOE4 and family history contribute heavily, equally powerful are modifiable factors like hypertension, obesity, and diabetes.

Supplement Shows Promise in Blocking Amyloid in Alzheimer’s

A new study shows that oral arginine, a naturally occurring amino acid, can significantly suppress amyloid-β aggregation in Alzheimer’s disease models. Researchers found that arginine not only prevented Aβ42 from clumping but also reduced plaques and inflammation in mouse and fruit fly models carrying Alzheimer’s-related mutations.

Early Brain Activity Differences Predict Addiction Risk in Boys vs Girls

A large-scale analysis of nearly 1,900 children found that those with a family history of substance use disorder show early differences in how their brains transition between activity states, long before any drug exposure. Girls with family history showed increased transition energy in introspective networks, suggesting greater difficulty shifting out of internal, stress-linked states.

Screen Time in Tweens Predicts ADHD, Slower Brain Growth

A large, two-year study of nearly 12,000 children found that higher screen time at ages 9–10 predicts an increase in ADHD symptoms, independent of a child’s starting symptom level. Brain imaging revealed that heavy screen use is associated with smaller cortical volume and disrupted development in regions critical for attention, cognition, and reward processing.

AI Interviews Outperform Standard Mental Health Rating Scales

A new study demonstrates that an AI assistant can conduct psychiatric assessment interviews with greater diagnostic accuracy than widely used mental health rating scales. In a sample of 303 participants with confirmed psychiatric conditions, the AI assistant Alba provided DSM-based diagnostic suggestions after a brief conversational interview, outperforming rating scales in eight of nine disorders.

Brain Releases Hidden Kinase to Supercharge Pain and Learning

New research reveals that neurons release a little-understood extracellular kinase called VLK to strengthen synaptic connections, providing a missing piece in how the nervous system adapts during learning and pain. The kinase phosphorylates EphB receptors outside the cell, which recruits NMDA receptors and amplifies synaptic signaling.

Shocking Disparities: Women Face Higher Risk of ECT

A large international survey of 858 electroconvulsive therapy recipients found that women are twice as likely as men to receive ECT and experience more adverse effects. Women reported higher rates of memory loss, greater feelings of coercion, and more harmful emotional outcomes, often describing the treatment as retraumatizing.

Cannabis Blunts Alcohol Cravings

A randomized, placebo-controlled trial shows that cannabis with active THC reduces immediate alcohol cravings and lowers drinking levels in heavy-drinking young adults. After smoking THC, participants not only drank less, they waited longer before taking the first sip and reported lower urges to drink.

Restoring Vision: Temporary Retinal Silencing Reverses Amblyopia

A new study in mice shows that briefly anesthetizing the retina of the weaker eye can restore its neural influence in the adult visual cortex. The treatment activates a specific burst-firing mode in thalamic neurons, a developmental mechanism that reopens plasticity even after the usual critical period has closed.

Lithium Fails to Slow Cognitive Decline in Alzheimer’s

A new meta-analysis of six randomized controlled trials shows that lithium supplementation does not significantly slow cognitive decline in people with mild cognitive impairment or Alzheimer’s disease. While preclinical evidence suggests lithium supports resilience against amyloid and tau pathology, these benefits failed to translate to clinical outcomes using traditional lithium salts.

Maternal Stress Speeds Up Baby Teething

New research shows that infants whose mothers had higher cortisol levels during late pregnancy experience significantly earlier eruption of primary teeth. Babies of mothers with the highest cortisol levels had, on average, four more teeth by six months than those of mothers with the lowest levels.

Night-Vision Disorders Share a Surprising Cellular Trigger

New research reveals that the loss of a single ion channel, TRPM1, is enough to produce persistent rhythmic oscillations in the retina, a feature observed in both congenital stationary night blindness and retinitis pigmentosa. By comparing Trpm1 and mGluR6 knockout mice, researchers identified a disrupted circuit between rod bipolar cells and AII amacrine cells that produces anti-phase oscillations interfering with visual signaling.
