Effects of Concussion and Repetitive Subconcussive Head Trauma

Repetitive Head Impacts Damage The Brain: A 'No Brainer,' Purdue Researchers Find

Research by scientists at Purdue goes a long way to eliminating any remaining doubt that repetitive head impacts, such as sustained by players in American football, result in brain abnormalities and impaired neurocognitive functioning during a football season, and that those effects persist long after the season.

Purdue Study First To Find Subtle Cognitive Deficits In High School Football Players From Repetitive Head Impacts

A 2010 study by researchers at Purdue University was the first to report that football players who displayed no clinically-observable signs of concussion, nevertheless showed measurable impairment of neurocognitive function (primarily visual working memory) on neurocognitive tests, as well as altered activation in neurophysiologic function on sophisticated brain imaging tests (fMRI).

Heading in Youth Soccer: The Debate Continues

A recent youth soccer safety campaign urging middle schools and under-14 soccer leagues to eliminate heading in the sport has sparked renewed interest in the controversial issue, but is also being criticized for advancing a slanted view of the science.

Concussions Lead To Microscopic Structural Changes In The Brain, Three New Studies Say

Concussions result in microscopic white matter and inflammatory changes to the brain, say three new studies published in the Journal of Neurosurgery. The studies add to a growing body of research suggesting that concussion can no longer be thought of as a transient injury resulting in a temporary disruption of brain function, but results in structural and electrophysiological changes which persist long after the injury occurs.

Microstructural Changes Detected In Hockey Players' Brains May Be Due To Concussive or Subconcussive Trauma

Using susceptibility-weighted imaging (SWI), researchers have identified microstructural changes in the brains of male and female college-level ice hockey players that could be due to concussive or subconcussive trauma.

Concussion Has Long Term Effect On Cognitive Function and Visual Processing, Studies Find

Sport-related concussion sustained in early life can have long-term implications for brain health and cognitive and sensory function, find two new studies. The findings add to a growing body of research on long-term deficits stemming from sport-related concussion, and suggest that concussive injuries can disrupt fundamental elements of higher-order neurocognition by chronically impairing attention, working memory, inhibition, and interference control, as well as lower-level sensory and perceptual processing.

History Of Concussion Linked To Increased Risk of Depression In Teens

A history of concussion is associated with more than a 3-fold increased risk of a current diagnosis of depression, even after controlling for age, sex, parental mental health, and socioeconomic status, finds a new study, which recommends that clinicians caring for youth with concussion be aware of this association and screen youth for symptoms of depression.

Four More Studies Find Causal Links Between CTE and Contact Sports and Suicide Scientifically Premature

Four new scientific papers add to the growing chorus of researchers pouring cold water on the now common assumption in the media and general population that contact sports causes CTE and that CTE causes those with the disease to commit suicide as scientifically premature.

Multiple Concussions: No Lingering Effect On Cognitive Function, Says Study

Adolescent athletes with a history of multiple concussions perform just as well on brief computerized tests of neurocognitive function than those without such history, although those who a history of two or more concussions self-reported more concussion symptoms, says a new study.

CTE: What Is Risk To Athletes Who Stop Playing Football After High School?

Men who played high school football in Minnesota in the decade after World War II are not increased risk of later developing dementia, Parkinson's or ALS compared with non-football playing high school males, according to a study by researchers at the Mayo Clinic.
