Serious knee injuries, including anterior cruciate ligament (ACL) ruptures in women’s and girls’ football, can be reduced through using injury prevention training, according to a new study by La Trobe University researchers.

Thousands of Americans develop chronic persistent symptoms—such as fatigue, cognitive difficulties (“brain fog”), and other debilitating issues—each year following acute infections from Lyme disease, COVID-19, and other pathogens. Efforts to identify causes and produce treatments have failed. However, 16 leading researchers think they know part of the problem: study design.

The chance of developing cognitive impairment was significantly higher for people who have had a heart attack, according to a study published in Stroke.

Patients with amyotrophic lateral sclerosis (ALS), or Lou Gehrig’s disease, live an average of only three years after symptoms begin, though some can survive closer to 10 years. What drives these differences in survival has remained a mystery.

Most people who met proposed clinical criteria meant to identify chronic traumatic encephalopathy (CTE) during life did not show hallmark brain changes of the disease at autopsy. The findings raise concerns that widespread clinical adoption of these criteria could lead to misdiagnosis and unintended mental health consequences for people at higher risk, including athletes and military veterans.
