Biomarker tests could help to diagnose people with mild traumatic brain injury when scans show nothing.

A confidential Navy program is studying whether intense fighter jet operations can cause devastating brain injuries in flight crews.

When Steven Simpson left the army after serving in Iraq, he spiralled into depression and was diagnosed with PTSD before finding the help he needed.

As anyone on the medical side of hockey will tell you, no two concussions are the same. No two people are the same so it makes perfect sense. How a player reacts to a blow to the head or a concussion or even to repeated concussions varies from player to player.

What all players have in common is the will. The desire to keep going in spite of injury or whatever other obstacles stand in their way.

A Harvard University survey reveals that one-third of former professional football players believe they have chronic traumatic encephalopathy (CTE), a degenerative brain disease caused by concussions and repeated head hits. The study, published in JAMA Neurology, is one of the largest to date on former NFL players' perceptions of their cognitive health and symptoms linked to CTE. Out of 1,980 respondents, 681 believed they had CTE, while over 230 had experienced suicidal thoughts and 176 had a diagnosis of Alzheimer's disease or dementia.

Researchers from the Radiological Society of North America (RSNA) analyzed the brain MRIs of 352 amateur soccer players, aged 18 to 53, both men and women. They discovered abnormalities in the white matter surrounding the brain, particularly in the frontal lobe, similar to CTE.

In Waves and Warn tells the story of Navy SEALS who are deployed to Iraq and Afghanistan time and time again, only to return stateside and experience a different type of war: a battle on their bodies and brains. The documentary, which premiered at the DOC NYC film festival, reveals how nightmares, explosive outbursts, severe pain, alcoholism and depression consumed the lives of these wartime heroes. Hopelessness and suicidal thoughts were the only way out, until they discovered an experimental treatment called ibogaine.

The “brain fog” of long COVID might be due to impaired lung function following a person’s infection, a new small-scale study says. Reduced gas exchange in the lungs – oxygen coming in, carbon dioxide going out -- appears to be associated with brain fog in long COVID, researchers will report in Chicago at next week’s annual meeting of the Radiological Society of North America.

A study led by the University of Glasgow has revealed differences in the brains of pediatric and adult patients that might explain the sometimes catastrophic outcomes seen in children following a traumatic brain injury.

A new study of high school football players found that concussions affect an often-overlooked but important brain signal. The findings are being presented next week at the annual meeting of the Radiological Society of North America (RSNA).
