Effects of Concussion and Repetitive Head Impacts Including Chronic Traumatic Encephalopathy

Repetitive Head Impacts: A Major Concern At All Levels of Sports

Brain trauma among football players may be less the result of violent helmet-on-helmet collisions that cause concussions as the accumulation of sub-concussive blows.  The long-term effects of such repetitive brain trauma are still unknown.

No Increased Risk Of Dementia, Parkinson's or ALS For Those Who Played H.S. Football Between 1946 and 1970, Studies Find

Are men who played high school football in Minnesota in the twenty-five years after World War II at increased risk of later developing dementia, Parkinson's or ALS compared with non-football playing high school males? Not according to two studies by researchers at the Mayo Clinic.

Study Linking Tackle Football Before Age 12 With Greater Risk Of Later Health Problems: Does It Hold Up Under Scrutiny?

A study by researchers at Boston University finding that athletes who were less than 12 years old at the time of their first exposure to tackle football had more behavioral and cognitive problems later in life than those whose age of first exposure to the sport was later has, predictably, garnered a great deal of attention from the mainstream media. In the interest of balanced and objective reporting, we asked a number of researchers and clinicians to review and comment on the study. Here's what they told us.

CTE: Media Continues To Be Ahead Of Science

Despite widespread media coverage and speculation regarding the late-life or post-retirement risks of cognitive impairment in athletes who engaged in sports involving repetitive blows to the head and high concussion risk, and assertions that CTE causes them to be at high risk of suicide, there have been virtually no peer-reviewed, well-designed scientific studies that establish, much less quantify, such risks.

Letting Kids Play Football is Not Child Abuse


The last three weeks have witnessed an all-out assault on the game of football, not coincidentally timed with the beginning of NFL training camps. First came a study reporting CTE in 110 of 111 brains of former NFL players. Following closely on the heels of that media circus was the publication last week of a new book by Dr. Bennet Omalu, Truth Doesn't Have a Side, and interviews in which Dr. Omalu, as he has for several years, argues that letting kids play football is the "definition" of child abuse. The not-so-surprising result has been a tsunami of emails in my Inbox asking for my views on the subject.

Are parents committing child abuse simply by allowing their kids to play a collision sport like football before middle school? Not unless it rises to the level of a callous and wanton disregard for a child's safety (e.g. reckless endangerment).

CTE: Is The Media Scaring Young Athletes To Death?

As someone who has been educating sports parents about head trauma in sports for the past seventeen years, and about the very real risk posed by chronic traumatic encephalopathy (CTE) for the last decade, it is not surprising that I receive emails from parents all the time expressing deep concern about stories in the media that have led them - wrongly - to fear that playing contact or collision sports, or suffering a sports-related concussion, especially one slow to heal, makes it inevitable that their child will develop CTE and is at greatly increased risk of committing suicide.

Sports Concussion Research, CTE, and the Media: Can The Disconnect Ever Be Repaired?

The public's perception that a direct causal link exists between repetitive head contact and chronic traumatic encephalopathy (CTE) is largely the result of one-sided, sensationalized, and biased reporting, argue four head injury researchers in a provocative editorial in the British Journal of Sports Medicine.

Playing With Concussion Doubles Recovery Time For High School Athletes

High school athletes who continue to play with a sport-related concussion (SRC) take nearly twice as long to be cleared for a full return to sports than those who are immediately removed from play, finds a new study.

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).
