Using advanced MRI scans and data taken from four studies, researchers found that 46% of the women with type 2 diabetes had signs of CMD, compared to just 26% of the men.

Researchers found that tirzepatide, a medication primarily used for treating type 2 diabetes and weight loss, reduced body weight, food intake and many measures of appetite more than placebo and liraglutide.

Microdosing psychedelics like LSD and psilocybin is gaining popularity, but science remains inconclusive. Small studies report modest benefits in mood, focus and sleep, though placebo effects loom large.

Researchers from CNRS and Université Paris Cité found that fatty diets and obesity alter astrocyte function in the striatum. In mice, manipulating these brain cells improved metabolism and restored learning ability.

Researchers in Japan created a precise method to simulate blood flow in brain aneurysms using partial MRI data. By focusing only on the aneurysm region, they reduced computational demands while increasing accuracy.

A study links partner loss, unemployment, and financial stress to Alzheimer’s biomarkers and brain structure changes. MRI and spinal fluid analysis of 1,200 individuals revealed gender- and education-dependent effects.

Study adds to growing evidence that social and psychological factors uniquely affect women’s heart health, offering new insights into why heart disease presents and progresses differently in women.

The research, led by Johns Hopkins University and funded by the federal government, focuses on hypertrophic cardiomyopathy, a genetic heart condition that can lead to sudden cardiac death, particularly in young individuals and athletes.

New research reveals that the protein Dystroglycan plays a critical role in forming and maintaining connections between nerve cells in the cerebellum.

Multimodal AI for ventricular Arrhythmia Risk Stratification (MAARS), predicts individual patients' risk for sudden cardiac death by analyzing a variety of medical data, records and contrast-enhanced MRI images of the patient's heart.
