Reuters: Stopping aspirin therapy may raise heart attack, stroke risk

Stopping low-dose aspirin therapy without good reason raises the likelihood of heart attack or stroke by nearly 40 percent, a large Swedish study suggests. Doctors commonly prescribe daily low-dose aspirin after a heart attack to reduce the risk of having a second cardiovascular event. But about one in six patients stop taking their aspirin within […]

News-Medical: Researchers discover new class of molecules that may protect brain from injury or diseases

Research led by Nicolas Bazan, MD, PhD, Boyd Professor and Director of the Neuroscience Center of Excellence at LSU Health New Orleans, has discovered a new class of molecules in the brain that synchronize cell-to-cell communication and neuroinflammation/immune activity in response to injury or diseases. Elovanoids (ELVs) are bioactive chemical messengers made from omega-3 very […]

Popular Science: Should I be worried about how many concussions I’ve had?

When it comes to concussions, most people don’t have to worry about the worst case scenario. Powerful head injuries and chronic blackouts from repeated pummeling or sports injuries inevitably lead to serious brain damage, yes, but most manage to avoid such constant concussions. But what about just one fist to the head? Or two helmet-denting […]

New Scientist: See-through brains reveal how stroke damages vital blood vessels

Now we can see stroke damage in 3D. A technique that turns mouse brains transparent has given us the most detailed view yet of how stroke cuts off the blood supply in the brain. Stroke damages the brain’s blood vessels, stopping oxygen and nutrients reaching cells. To understand this impact, researchers usually examine thin brain […]

U.S. News & World Report: TIAs: Don’t call them ministrokes

Transient ischemic attacks (or TIAs, for short) have long been nicknamed ministrokes since they don’t cause permanent damage to the brain. But experts are increasingly pushing back on that moniker because a TIA reflects more than just a tiny blip in your brain function: It should be viewed as a “warning stroke” that warrants medical […]

News-Medical: New pig model for stroke could accelerate drug discovery process

It is well-known in the medical field that the pig brain shares certain physiological and anatomical similarities with the human brain. So similar are the two that researchers at the University of Georgia’s Regenerative Bioscience Center have developed the first U.S. pig model for stroke treatments, which will provide essential preclinical data and speed the […]

NPR: 1 in 5 teens reports a concussion diagnosis

Concussions have gotten a lot of attention in recent years, especially as professional football players’ brains have shown signs of degenerative brain disease linked with repeated blows to the head. Now, a new analysis confirms what many doctors fear — that concussions start showing up at a high rate in teens who are active in […]

Medical News Today: Teenage concussion linked to later risk of MS

A new study provides further evidence of the potential long-term harms of head trauma, after finding that individuals who suffer a concussion in adolescence may be at greater risk of developing multiple sclerosis. Concussion is a form of traumatic brain injury (TBI) caused by a sudden blow or jolt to the head, which can interfere […]

Neurology Advisor: Risk of stroke, mortality reduced with high stem cell factor

High levels of stem cell factor (SCF) are associated with reduced risk of mortality and cardiovascular events, according to a study published in the Journal of Internal Medicine. Harry Björkbacka, PhD, from Lund University in Sweden, and colleagues examined the correlation between circulating levels of SCF and risk for development of cardiovascular events and death. […]
