Alcohol raises dementia risk at every level of drinking, genetic study shows

Researchers using two major cohorts and Mendelian randomization found that alcohol consumption, whether light or heavy, raises the risk of dementia. Genetic evidence shows no safe level of drinking, challenging the belief that moderate intake protects brain health.

Scientists map step-by-step activation of brain receptors

When it comes to brain proteins, small changes can make a dramatic difference. Researchers studying NMDA (N-methyl-D-aspartate) receptors, which are essential for learning, memory and moment-by-moment consciousness, know that even slight changes in their activity level can mean the difference between normal function and serious neurological disorders.

Skin-to-skin care linked to stronger brain development in preterm infants

Preterm infants born before 32 weeks who received more skin-to-skin contact while in the hospital showed stronger brain development in areas tied to emotion and stress regulation than babies who received less skin-to-skin care, according to a study published in the September 24, 2025, issue of Neurology, the medical journal of the American Academy of Neurology.

Long COVID linked to heavier periods and symptom flare-ups during menstruation

Researchers found that long COVID is linked to heavier, longer, and more irregular bleeding without disrupting ovulation. Symptom severity also peaks around menstruation, likely driven by hormonal and immune changes.

Can changing food texture reduce how much we eat? Dutch study investigates

A new randomized controlled trial protocol from the Netherlands will test whether altering the texture, and thus the eating rate, of ultra-processed foods can reduce daily energy intake. The study will investigate how sensory properties, such as food hardness, affect metabolism, appetite, and microbiome composition.

Precision targeting of the centromedian nucleus offers hope for people with drug-resistant epilepsy

It is estimated that one-third of the 50 million people worldwide with epilepsy are resistant to anti-seizure medications. These patients, having drug-resistant epilepsy, have limited treatment options beyond surgery to control their seizures.

New imaging technique enhances live-cell visualization in standard lab setups

Optical diffraction tomography (ODT) has long been recognized for its potential in non-invasive, label-free imaging of live biological cells. However, a major challenge arises when ODT is applied to standard multi-well cell culture plates, a common tool use under realistic laboratory conditions for biological studies.

Ketogenic diets may lower migraine frequency and medication use

This narrative review argues that the migraine brain is hypometabolic, with converging evidence of mitochondrial dysfunction, impaired glucose handling, neuroinflammation, microbiome shifts, and obesity-related pathways. It proposes ketogenic diets as a plausible preventive strategy that may reduce monthly migraine days and medication use, while emphasizing the need for larger, rigorous randomized trials and careful clinical oversight.
