Waterloo researchers unveil new screening tool and data at 2016 AAIC

Two studies involving University of Waterloo researchers presented this week at the 2016 Alzheimer's Association International Conference (AAIC) in Toronto highlight a new diagnostic tool that can identify Alzheimer's disease long before the onset of symptoms as well as the increasing prevalence of Alzheimer's disease in Ontario.

Study sheds light on neuronal circuits during risky behavior

New research sheds light on what's going on inside our heads as we decide whether to take a risk or play it safe. Scientists at Washington University School of Medicine in St. Louis located a region of the brain involved in decisions made under conditions of uncertainty, and identified some of the cells involved in the decision-making process.

Novel noninvasive scoring system can help predict strength and health of vascular network in the brain

A new study presented at the Society of NeuroInterventional Surgery's 13th Annual Meeting in Boston found that the Opercular Score Index (OIS) is a practical, noninvasive scoring system that can be used to predict the strength and health of the vascular network in the brain (known as collateral robustness) and good clinical outcome among stroke patients undergoing endovascular recanalization.

Penn researchers use iron-containing nanoparticles to reduce plaque and prevent tooth decay

The bacteria that live in dental plaque and contribute to tooth decay often resist traditional antimicrobial treatment, as they can "hide" within a sticky biofilm matrix, a glue-like polymer scaffold.
