Genetic Roots of Depression Reveal Strong Suicide Risk Signals

New research shows that depression beginning before age 25 has a much stronger hereditary component than depression that emerges later in life. By analyzing genetic data from over 150,000 people with depression, researchers identified distinct genetic regions linked specifically to early-onset cases.

No Evidence the Gut Microbiome Causes Autism

Experts reviewing decades of research conclude there is no scientific evidence that the gut microbiome causes autism. They highlight major flaws in observational studies, mouse experiments, and clinical trials, including inadequate sample sizes and contradictory findings.

Why Women Face Worse Long COVID

New research reveals that women with long COVID show distinct biological disruptions — including gut inflammation, anemia, and abnormal hormone levels — that may explain their heightened and persistent symptoms. These findings emerged from immune, biomarker, and genetic analyses in people one year after infection.

Low Income, Vision Loss, and Isolation Drive Dementia Risk

A new study reveals that people with lower incomes and those from historically underrepresented racial and ethnic groups carry a higher burden of modifiable dementia risk factors. Vision loss and social isolation were among the most significant contributors for those living below the poverty line, suggesting that better access to healthcare and community support could have major protective effects.

Low Omega-3 Linked to Higher ADHD Symptoms

A new study reveals that low omega-3 fatty acid intake is associated with increased ADHD symptoms among Palestinian adolescents. Researchers found that socioeconomic disparities—particularly those limiting access to omega-3–rich foods like fish and nuts—intensify ADHD-related behavioral and attention difficulties.

Alzheimer’s Drug Reduces Amyloid but Fails to Restore Brain Waste Flow

Researchers found that lecanemab, the Alzheimer’s drug designed to clear amyloid-β plaques, does not improve the brain’s waste clearance system in the short term. In a three-month study using MRI-based DTI-ALPS imaging, scientists observed no measurable recovery in glymphatic function after treatment.

Speaking Multiple Languages May Slow Down Biological Aging

A large-scale study of more than 86,000 Europeans found that speaking multiple languages may help slow biological and cognitive aging. Using artificial intelligence to assess “biobehavioral age gaps,” researchers discovered that multilingual individuals were over twice as likely to show signs of healthy aging compared to monolinguals.

Everyday Speech May Reveal Early Cognitive Decline

Researchers found that everyday speech timing — including pauses, fillers, and subtle patterns — strongly reflects executive function, a key cognitive system that supports memory and flexible thinking. Using AI to analyze natural speech, the study showed that these linguistic features can predict cognitive-test performance independent of age, sex, or education.

Stress Undermines Brain Circulation, Increases Dementia Risk

Researchers found that a rare class of neurons—type-one nNOS neurons—plays a central role in regulating brain blood flow and coordinating neural activity in mice. Removing these stress-vulnerable cells caused major drops in vessel oscillations and widespread reductions in electrical signaling, suggesting a crucial link between neuron loss, blood-flow decline, and brain-function impairment.

Autism and ADHD Brain Patterns Reveal Shared Biological Roots

A new study shows that autism symptom severity, rather than a formal diagnosis, aligns with shared brain-connectivity patterns across children diagnosed with autism or ADHD. Stronger autistic traits were linked to heightened connectivity between frontoparietal and default-mode networks, regions central to social cognition and executive functions.

Low Choline Could Be a Hidden Driver of Anxiety

A large meta-analysis of 25 studies found that people with anxiety disorders have significantly lower levels of choline, a vital brain nutrient, compared to individuals without anxiety. This reduction was especially pronounced in the prefrontal cortex, which helps regulate emotion and behavior.

Psychedelics Calm Stress Circuits to Reduce Alcohol Drinking

New research shows that psilocin, the active metabolite of the psychedelic psilocybin, may reduce alcohol consumption by calming stress-sensitive neurons in the central amygdala. In female mice exposed to long-term alcohol use, psilocin dampened the hyperactivity of these neurons, temporarily reducing drinking.
