Schizophrenia Biomarker Can Be Detected In Human Hair

A subtype of schizophrenia is related to abnormally high levels hydrogen sulfide in the brain, report researchers at the RIKEN Center for Brain Science who worked with model mice, postmortem human brains, and people with schizophrenia. Experiments showed that this abnormality likely results from a DNA-modifying reaction during development that lasts throughout life. In addition […]

Slower Walkers Have Older Brains And Bodies At Age 45

The walking speed of 45-year-olds, especially their fastest walking speed without running, can be useful as a marker of their aging brains and bodies, new research from Duke University[1] suggests. Slower walkers were shown to have “accelerated aging” on a 19-measure scale devised by researchers, and their lungs, teeth and immune systems tended to be […]

Depression Symptoms In Alzheimer’s Could Be Signs For Cognitive Decline

Depression symptoms in cognitively healthy older individuals together with brain amyloid, a biological marker of Alzheimer’s, could trigger changes in memory and thinking over time, researchers from Massachusetts General Hospital (MGH) report. “Our research found that even modest levels of brain amyloid deposition can impact the relationship between depression symptoms and cognitive abilities. This raises […]

Portable Breath Analyzer Spots Lung Disease Faster Than Doctors

A small, portable breath monitor can quickly and accurately detect acute respiratory distress syndrome, researchers report. Acute respiratory distress syndrome (ARDS) is an often deadly disease that causes fluid to leak into the lungs and demands early diagnosis. To detect the condition today, doctors rely heavily on their own judgment and time-consuming tests. The researchers […]
