Researchers identify risk factors for postoperative cerebral ischemia in patients with moyamoya disease

The buildup of fats, cholesterol, calcium, and immune cells within the blood vessel can lead to the narrowing or even complete blockage of the blood vessel.

PET imaging reveals widespread brain receptor deficits in schizophrenia

A groundbreaking study using positron emission tomography (PET) imaging has found that patients with schizophrenia had significantly lower muscarinic acetylcholine M1 receptor availability (~13% to 19%) across multiple brain regions compared with healthy individuals.

Researchers rank 11 preeclampsia therapies as top candidates for further development

Researchers ranked 83 preclinical candidates for preventing or treating preeclampsia and eclampsia, identifying 11 as having high potential for further development. The analysis also revealed limited target diversity, moderate bias, inactive programs, and animal models that may not fully represent human pregnancy

Nine gut bacteria linked to future type 2 diabetes risk

Research identifies specific gut microbes associated with future type 2 diabetes risk, emphasizing the impact of dietary fiber on microbiome health.

Study reveals how glial cells regulate brain injury and recovery

Traumatic brain injury (TBI) affects millions of people worldwide every year and remains a major cause of long-term disability, cognitive decline, and neurological complications.

Study provides new insights into biological processes linked to Huntington’s disease

A study conducted by the Sant Pau Research Institute (IR Sant Pau) and Hospital de Sant Pau has identified for the first time in living individuals a brain pattern related to the tau protein that changes according to the stage of Huntington's disease.

Allergies show a small but significant link to later cancer risk

A systematic review and meta-analysis of 28 cohort-based studies found a weak but statistically significant association between allergic diseases and later cancer incidence. The signal was strongest in the Western Pacific region and among people with asthma, but high heterogeneity and limited subgroup evidence mean the findings require caution.

Nasal viruses may drive allergic rhinitis, and ribavirin shows early promise as a targeted spray treatment

Nasal commensal viruses may worsen allergic rhinitis by activating type I IFN-linked neutrophils and NET formation. Ribavirin reduced nasal viral abundance and improved symptoms in mice and in a small phase 2 trial.

New human protein atlas maps how cancer rewires the body’s tissues

Researchers created a DIA-MS atlas of 13,609 proteins across 2,856 samples from fetal, healthy adult, paired non-tumor, and tumor tissues. The resource maps tissue-specific protein patterns, cancer-associated changes, organ-specific drug-toxicity signals, and candidate therapeutic targets.

PMOS rethink reframes a common hormone disorder as a whole-body disease

A new review reframes PCOS, now proposed as PMOS, as a systemic endocrine and metabolic disorder shaped by genetic, epigenetic, ovarian, metabolic, and neuroendocrine pathways. It highlights why inconsistent diagnosis and symptom-focused care have limited progress, while targeted therapies, biomarkers, machine learning, and organ-on-chip models may support more personalized treatment.

New biological age tools could reveal health risks before symptoms appear

A JCI review traces biological age measurement from functional tests and blood biomarkers to epigenetic, proteomic, imaging, wearable, and AI-based clocks. It finds that these tools can improve risk prediction beyond chronological age, but standardization, interpretability, and prospective validation are needed before routine clinical use.

Gut microbes may help explain why obesity and type 2 diabetes become harder to reverse

This review describes how gut microbial messengers, including SCFAs, microbiota-modified bile acids, neuroactive metabolites, and extracellular vesicles, may shape obesity and type 2 diabetes through the microbiota-gut-brain axis.

Glucosamine may worsen Alzheimer’s by fueling abnormal brain glycosylation

A Nature Metabolism study identifies brain hyperglycosylation as a metabolic driver of Alzheimer’s disease, with increased N-glycan biosynthesis seen in human AD tissue and mouse models. Reducing glycosylation improved memory in AD mice, while glucosamine worsened memory deficits in 5xFAD mice and was associated with poorer outcomes in dementia patients.

Review explores diagnosis and management of perioperative anaphylaxis during anesthesia

Perioperative anaphylaxis is a rare, life‑threatening condition during anesthesia. The unique setting – multiple drugs, patient draping, and altered physiology – causes higher mortality than anaphylaxis elsewhere.

Gut microbes may reveal who is at risk of type 2 diabetes years before diagnosis

A large Swedish prospective cohort study found that specific gut microbial species and metabolic pathways measured years before diagnosis were associated with future type 2 diabetes risk. The findings suggest that gut microbiome composition and functional potential may help explain T2D development, but replication is needed before clinical use.

PET/CT scans reveal biological activity of aggressive head and neck tumors

A research team led by the Medical University of Vienna has demonstrated in a recent study that the biological characteristics of a subgroup of head and neck tumors - which are very aggressive in many cases - are reflected in modern imaging techniques.

Large human islet study reveals new insights into diabetes risk

Diabetes is the most common and serious chronic disease worldwide, characterized by insufficient insulin to maintain proper blood glucose levels.

AI-driven model predicts type 1 diabetes risk with greater accuracy

Researchers use machine learning and genetic analysis to uncover type 1 diabetes risk factors, improving prediction accuracy and identifying patient subtypes.

Study links microplastics in arterial plaque to fourfold increase in stroke risk

In a Perspective published today in the inaugural issue of Brain Health (https://doi.org/10.61373/bh026p.0006), an international team of investigators argues that the human microplastic burden has crossed the threshold from environmental concern to brain health emergency. The article appears alongside the launch of Brain Health, a new peer-reviewed journal from Genomic Press dedicated to the science of lifelong brain resilience.
