New research has drawn a link between changes in the brain鈥檚 anatomy and biomarkers that are known to appear at the earliest stages of Alzheimer鈥檚 disease (AD), findings that could one day provide a sensitive but non-invasive test for AD before cognitive symptoms appear.
Scientists have known for some time that one of the first signs of AD is buildup of amyloid-Beta and tau proteins in the brain. They have also known that the hippocampus atrophies and loses volume in some AD patients years before cognitive decline.

A study published in the Proceedings of the National Academy of Sciences has shown that musical training helps people hear speech聽syllables in loud environments, and has shown how this happens. Using functional magnetic resonance imaging (fMRI), researchers Yi Du and Robert Zatorre monitored brain function as musicians and non-musicians listened to speech fragments and varying background聽noise levels.

A clinical trial almost ten years in the making has revealed that risky, but powerful, clot busting drugs and medical devices do not improve outcomes for patients experiencing deep vein thrombosis (DVT), nor do they prevent the development of post-thrombotic syndrome (PTS) when compared with conventional blood thinning medications. The results of the Acute Venous Thrombosis: Thrombus Removal with Adjunctive Catheter-Directed Thrombolysis (ATTRACT) study are published in the New England Journal of Medicine.
