Men Are Three Times As Likely to Die From Brain Injuries

A 2021 analysis of U.S. mortality data highlights disparities in traumatic brain injury (TBI)-related deaths, which disproportionately affect older adults, men, and certain racial and ethnic groups. Suicides remain the leading cause, followed by unintentional falls, with older adults (75+) and American Indian/Alaska Native individuals experiencing the highest mortality rates.

Head Trauma May Reactivate Dormant Viruses, Increasing Alzheimer’s Risk

New research suggests that concussions and repetitive head trauma may reactivate dormant viruses like HSV-1 in the brain, potentially triggering neurodegenerative diseases such as Alzheimer’s. Using a brain tissue model, scientists observed that head trauma caused latent HSV-1 to awaken, leading to hallmark Alzheimer’s markers such as amyloid plaques, inflammation, and neuronal damage.

This shows a high school football player and a brain.

Concussion Impacts Brain Activity and Cognition in High Schoolers

Concussions affect aperiodic brain activity, a key signal often dismissed as "background noise," which plays a role in brain excitability and cognitive function. High school football players who experienced concussions showed slowed aperiodic activity, correlating with worse memory, concentration, and post-concussion test scores.

Blood Tests Uncover Lasting Damage Following Single Brain Injury

A new study reveals that moderate-to-severe traumatic brain injuries (TBI) can have long-lasting effects, persisting for decades. Using advanced MRI scans, blood biomarkers, and cognitive tests, researchers found that survivors show signs of chronic brain pathology even 22 years after their injury.

One-Third of Former NFL Players Fear They Have CTE

A new study of nearly 2,000 former NFL players reveals that about one-third believe they have chronic traumatic encephalopathy (CTE), a condition linked to repeated head trauma. Those who believed they had CTE reported higher rates of cognitive problems, depression, chronic pain, and suicidality compared to those who did not.

Brain Scans Improve Concussion Care by Predicting Lasting Symptoms

Advanced MRI scans, particularly diffusion tensor imaging (DTI), have shown promise in predicting which concussion patients are at risk for long-term symptoms. While standard CT scans often fail to detect brain abnormalities in concussion cases, DTI can identify subtle changes in the brain’s white matter that are linked to persistent symptoms. This method could significantly improve the accuracy of prognoses, helping to identify patients who may need further follow-up and treatment. Researchers also found that specific blood biomarkers could help determine which patients would benefit most from a DTI scan.

Concussions Linked to Higher Brain Iron

Individuals experiencing headaches after concussions may have higher levels of iron in certain brain regions, indicating cell injury. The research examined 60 people with post-traumatic headaches from mild traumatic brain injuries, comparing them to 60 people without such injuries.

Persistent Brain Repair Signals in Ex-NFL Players

A new study on former NFL athletes reveals prolonged high levels of the repair protein TSPO, indicating long-term brain inflammation post-injury. This protein, usually elevated after a traumatic brain injury (TBI) as part of the immune response, was found at high levels years after athletes ended their sports careers.

Brain Impacts of Intimate Partner Violence

Researchers, in a comprehensive brain autopsy study, discovered significant vascular and white matter damage in women who experienced intimate partner violence. Unlike in male contact sports athletes, no evidence of CTE was detected.

Study Sheds Light on Elusive Minimally Conscious States

A new study has mapped the prevalence of an infrequent but impactful condition arising from acquired brain injuries: the minimally conscious state. This state manifests when victims of brain injuries exhibit faint indications of awareness despite a major loss of consciousness.

Early Concussions Tied to Faster Cognitive Decline

A recent study reveals a link between early-life concussions and faster cognitive decline in later years. Conducted on World War II veteran twins, the research showed that twins with a history of traumatic brain injury (TBI) scored lower on cognitive tests and exhibited quicker decline than their non-injured counterparts.

From Concussion to Alzheimer’s: Mini-Brain Unlocks Time-Sensitive Link

Researchers developed a "traumatic brain injury (TBI) on a chip" to explore the links between concussions and Alzheimer's disease. Using clusters of neurons from embryonic mice, they exposed the "miniature brain" to g-forces mimicking those experienced by football players.
