Self-reported suicide attempts rising in black teens as other groups decline
Self-reported suicide attempts rose significantly in African American teens, while they fell in teens of other ethnic backgrounds throughout an almost 20-year study. Researchers report suicide attempts increased at an accelerating rate in African American female teenagers, even as overall female suicide attempts declined.... Read More...
Researcher uses sweat monitors to predict behavioral issues in adolescents severely affected with autism
Electrodermal activity, which results in an increased level of sweat, was able to determine when an adolescent with server ASD was about to embark on aggressive behavior 60% of the time.... Read More...
New genetic link found for some forms of SIDS
Researchers tie some cases of sudden infant death syndrome (SIDS) with a genetic mutation that causes an inability to process milk, leaving the child vulnerable to sudden heart failure. Future studies will explore if a drug called Elamipretide can help reduce cardiac events in children with the mutation.... Read More...
Dog ownership associated with longer life, especially among heart attack and stroke survivors
Owning a dog was associated with a 33% lower risk of death for heart attack survivors who lived alone, and a 27% reduced risk for those who suffered a stroke, compared to those who did not own a pet. Additionally, dog ownership was linked to a 24% reduced risk of all-cause mortality and a 31% reduced risk of death by heart attack or stroke.... Read More...
Study pinpoints Alzheimer’s plaque emergence early and deep in the brain
Researchers use SWITCH technology to label amyloid plaques in mouse models of Alzheimer's disease so they could be imaged in fine detail at different ages. They were consistently able to see the plaques first emerged in deep brain structures and tracked circuits, such as the Papez memory circuit, to spread throughout the brain as the animal aged....
