Gut bacteria may help explain why fatigue appears before illness

A small study of healthy Japanese adults found that fatigue was associated with distinct gut microbiome, microbial gene, and fecal metabolite patterns. The findings suggest fatigue may track with altered microbial energy metabolism and oxidative stress-related functional potential, but larger longitudinal studies are needed to test causality and clinical value.

UCLA researchers identify brain circuit controlling memory organization

When a person has a new experience, their brain faces a subtle but critical decision: should this experience be categorized with other stored memories, or should it be filed away as its own new memory? Getting it right allows the brain to help people navigate the world.

Gene mapping highlights strong immune and brain connections in depression

Neurons and white blood cells differ greatly in shape, function, and location within the body. However, researchers at the University of São Paulo (USP) in Brazil discovered that certain genes are equally dysregulated in both cell types in people with depression.

Molecular switch protein Ten4 guides neuron migration in the developing brain

During brain development, neurons can regulate their movement until they reach their final destination thanks to a "molecular switch" involving the protein Teneurin 4 (Ten4).

Semaglutide for weight loss was linked to a sharp drop in alcohol use in this case report

A 2026 case report describes a 34-year-old man with obesity and alcohol use disorder whose semaglutide treatment for weight loss was associated with a marked drop in drinking over 10 months, with his AUDIT score falling from 27 to 7 and alcohol use dropping from about 15 drinks per week to half a beer per month. The authors frame this as a promising but preliminary finding that adds to growing evidence on GLP-1 drugs and alcohol use, while also stressing that this was a single case and that better AUD screening in family medicine remains important.

New review reveals complex polygenic architecture underlying common epilepsies

An insightful mini-review published in Genomic Psychiatry synthesizes the rapidly expanding landscape of molecular genetic research on common epilepsies, assembling evidence from genome-wide association studies, whole-exome sequencing projects, and advanced statistical modeling to illuminate the polygenic architecture that underpins these heterogeneous neurological disorders.

New review calls for biologically grounded approach to psychiatric diagnosis

A comprehensive invited review published today in Brain Medicine confronts one of the most persistent paradoxes in modern medicine: psychiatry remains the only major clinical discipline that diagnoses complex illness primarily through conversation and symptom checklists, while fields such as oncology and cardiology long ago embraced laboratory markers, imaging, and molecular profiling.
