Insomnia Isn’t Just About Sleep, Your Personality Plays a Role

Certain personality traits significantly influence the risk of developing insomnia. People with high levels of neuroticism—a trait linked to emotional instability—were much more likely to experience sleep disturbances.

This shows two heads, sound waves, and a brain.

Midlife Hearing Loss Linked to Faster Brain Aging

A Brazilian study of over 800 adults in their 50s shows that hearing loss is strongly linked to accelerated cognitive decline. Participants with hearing loss experienced faster reductions in memory, language, and executive function over eight years.

Ultra-Processed Foods Disrupt Infant Gut Health

A Brazilian study of 728 infants found that ultra-processed foods can harm gut microbiota diversity, with stronger effects in children who were not breastfed. Breastfed infants had higher levels of beneficial Bifidobacterium, while non-breastfed children consuming processed products showed elevated levels of bacteria linked to obesity and gastrointestinal issues.

Maternal Childhood Trauma Linked to Rapid Weight Gain in Baby Boys

A new study reveals that maternal childhood trauma—such as neglect or abuse—can trigger rapid weight gain in male infants as early as the first two months of life. Researchers found that boys born to mothers who experienced early-life adversity gained significantly more weight per day than average, despite being full-term, healthy, and mostly breastfed.

Disrupted Myelin Protein Implicated in Schizophrenia

A new study has identified the protein hnRNP A1 as a key player in the production and maintenance of myelin, the fatty sheath that insulates nerve fibers in the brain. Myelin loss is common in disorders like multiple sclerosis and schizophrenia, and this research shows that hnRNP A1 disruptions can impair myelination at the molecular level, even before behavioral symptoms appear.

Weight Training May Slow Cognitive Decline and Protect Aging Brains

A new study shows that weight training not only boosts physical strength but also protects the brains of older adults with mild cognitive impairment. After six months of twice-weekly resistance training, participants showed memory improvements and protection against brain atrophy in regions linked to Alzheimer’s disease.

Long-term Impact of Prenatal Cannabis Exposure Explored

A study examining the effects of prenatal exposure to synthetic cannabinoids in rats found that the drug leads to long-term health issues in their offspring. Male rats showed an increased sensitivity to CO2, making them more prone to panic-like behavior, while females exhibited cardiovascular problems like hypertension and tachycardia.

Mapping Fear: Brain Circuit That Detects and Remembers Threats Revealed

A new study has mapped a brain circuit responsible for detecting threats and forming fear memories. The hippocampus, known for spatial navigation, also plays a role in recognizing dangers, with the subiculum transferring threat information to the hypothalamus.

Brain Overgrowth Linked to Autism Symptom Severity

Researchers have identified a link between brain overgrowth and the severity of social and communication symptoms in children with autism spectrum disorder (ASD). By analyzing MRI scans and conducting experiments with brain organoids, the study found that children with the most severe ASD symptoms had significantly larger brains. This enlargement is associated with altered activity of the enzyme Ndel1, which plays a crucial role in neuron development. The findings open new avenues for understanding ASD and its varying symptom severity.

Molecular Alterations in Brain Tissue Provide Clues to Suicidal Ideation

Researchers have identified molecular alterations in the blood and brain tissues of individuals who committed suicide, offering new insights into susceptibility factors and therapeutic targets. The study analyzed genetic, protein, and metabolic changes, suggesting these alterations could serve as risk markers for suicidal behavior.

Adolescent Stress Alters Brain Genes, Affecting Adult Behavior

A new study reveals that excessive stress during adolescence can lead to long-lasting changes in gene expression in the brain, particularly those related to bioenergy functions. This research indicates that such alterations may disrupt cell respiration and contribute to behavioral issues and psychiatric disorders in adulthood.
