A sodium surprise

Irregular heartbeat — or arrhythmia — can have sudden and often fatal consequences. A biomedical engineering team at Washington University in St. Louis examining molecular behavior in cardiac tissue recently made a surprising discovery that could someday impact treatment of the life-threatening condition.

Blood test IDs key Alzheimer’s marker

A study led by researchers at the School of Medicine suggests that measures of amyloid beta in the blood have the potential to help identify people with altered levels of amyloid in their brains or cerebrospinal fluid. The test could identify people who have started down the path toward Alzheimer’s years before symptoms occur.

In autism, genes drive early eye gaze abnormalities

New research has uncovered compelling evidence that genetics plays a major role in how children look at the world and whether they have a preference for gazing at people’s eyes and faces or at objects.The discovery by researchers at the School of Medicine and Emory University adds new detail to understanding the causes of autism spectrum disorder.

Sleep, Alzheimer’s link explained

Research from Washington University School of Medicine, Radboud University Medical Centre in the Netherlands, and Stanford University shows that disrupting just one night of sleep in healthy, middle-aged adults causes an increase in a brain protein associated with Alzheimer’s disease.

Popular heartburn drugs linked to higher death risk

Popular heartburn drugs called proton pump inhibitors (PPIs) have been linked to a variety of health problems, including serious kidney damage, bone fractures and dementia. Now, a new study from Washington University School of Medicine in St. Louis shows that longtime use of the drugs also is associated with an increased risk of death.
