RELEASE: Brain scans may help diagnose neurological, psychiatric disorders

There are no laboratory tests to diagnose migraines, depression, bipolar disorder and many other ailments of the brain. Doctors typically gauge such illnesses based on self-reported symptoms and behavior. Now, a new study shows that a kind of brain scan called functional connectivity MRI (fcMRI) – which shows how brain regions interact – can reliably detect fundamental differences in how individual brains are wired. As such, the technique potentially could be used to distinguish healthy […]

Virus infects rare intestinal cells in mice; findings point to therapeutic strategy Norovirus – the highly contagious gastrointestinal illness best known for spreading rapidly on cruise chips, in nursing homes, schools and other densely populated spaces – kills an estimated 200,000 people annually, mostly in the developing world. There’s no treatment or vaccine to prevent the illness, and scientists have understood little about how the infection gets started. Now, researchers at Washington University School of […]

RELEASE: Antibiotic use increases risk of severe viral disease in mice

People infected with West Nile virus can show a wide range of disease. Some develop life-threatening brain infections. Others show no signs of infection at all. One reason for the different outcomes may lie in the community of microbes that populate their intestinal tracts. A study from Washington University School of Medicine in St. Louis shows that mice are more susceptible to severe West Nile disease if they have recently taken antibiotics that change the […]
