Bill Gates Wants To Jump-Start A Test For Alzheimer's
Besides a cure, what do those afraid of Alzheimer's disease need most? According to entrepreneur and philanthropist Bill Gates, a key need is a "reliable, affordable, and accessible" diagnostic test. To jump-start that research, Gates announced today that he has joined a coalition of philanthropists who are investing $30 million to create a venture fund called Diagnostics Accelerator. "We need a better way of diagnosing Alzheimer's -- like a simple blood test or eye exam -- before we're able to slow the progression of the disease," Gates wrote in a statement announcing the investment. "Imagine a world where diagnosing Alzheimer's disease is as simple as getting your blood tested during your annual physical." (LaMotte, 7/17)

CTE has been part of the national lexicon in the U.S. since the 2015 movie Concussion dramatized the discovery of this degenerative brain disease among football players. Chronic traumatic encephalopathy is found among people who've had head injuries. Though not everyone with head trauma develops CTE, the group that's come to be most associated with it is football players, whose brains can be routinely jarred by hard hits. The disease has been linked to depression, dementia and even suicide among those who play the game. (Goldman, 7/17)

An Aspirin A Day For Heart Health? It May Depend On Your Weight
A daily dose of baby aspirin is widely recommended for heart disease prevention, but a one-dose-fits-all approach may not work. A new analysis, in The Lancet, looked at data from 10 randomized trials and found that the size of the dose and the weight of the patient have significant effects on outcome. Researchers found that a daily dose of 75 to 100 milligrams of aspirin lowered the risk of cardiovascular events by 23 percent for people weighing less than 154 pounds, but had no effect in those weighing more. In people over 154 pounds, low-dose aspirin increased the risk for a fatal cardiovascular event. (Bakalar, 7/17)

They also recorded five factors associated with cardiovascular risk: waist circumference, blood pressure, HDL or “good” cholesterol, triglycerides and insulin resistance. (Bakalar, 7/17)
