OBJECTIVE:Cerebral concussion is common in collision sports such as football, yet the chronic neurological effects of recurrent concussion are not well understood. The purpose of our study was to investigate the association between previous head injury and the likelihood of developing mild cognitive impairment (MCI) and Alzheimer's disease in a unique group of retired professional football players with previous head injury exposure. METHODS:A general health questionnaire was completed by 2552…

Clinically Relevant Recurrent Concussion and Risk of Depression in Retired Professional Football Players

The findings suggest a possible link between recurrent sport-related concussion and increased risk of clinical depression among retired professional football players with prior head injury exposure.

Recurrent concussion and risk of depression in retired professional football players.

The findings suggest a possible link between recurrent sport-related concussion and increased risk of clinical depression and emphasize the importance of understanding potential neurological consequences of recurrent concussion.

Prevalence and Characterization of Mild Cognitive Impairment in Retired National Football League Players

There may be an increased prevalence of late-life cognitive impairment in retired NFL players, which may reflect diminished cerebral reserve, and the need for larger, controlled studies on this issue is emphasized.

An index predictive of cognitive outcome in retired professional American Football players with a history of sports concussion

It is demonstrated that a unique combination of CR, sports concussion, and game-related data can predict cognitive outcomes in participants who had been retired from professional American football for an average of 20 years.

Long-term health outcomes after exposure to repeated concussion in elite level: rugby union players

Despite a high number of concussions in RIRP, differences in mental health, social or work functioning were not found late after injury, and Subtle group differences were detected on two cognitive tests, the cause of which is uncertain.

Increased risk for neurodegenerative diseases in professional athletes

Background Although concussion and sport-related traumatic brain injury is being acknowledged as a major public issue, especially in professional football players, current study is mostly limited to

Mild Cognitive Impairment in Retired Professional Football Players With a History of Mild Traumatic Brain Injury: A Pilot Investigation

It is suggested that a history of multiple mild TBIs does not significantly alter the overall neuropsychological profile of individuals with MCI; confirmation of this will require longitudinal research with larger sample sizes.

Foot and ankle Osteoarthritis and Cognitive impairment in retired UK Soccer players (FOCUS): protocol for a cross-sectional comparative study with general population controls

To determine whether former professional male footballers have a higher prevalence than the general male population of: foot/ankle pain and radiographic OA; and cognitive and motor impairments associated with dementia and Parkinson’s disease.

Epidemiology of neurodegeneration in American-style professional football players

A growing body of research supports the hypothesis that professional football players are at an increased risk of neurodegeneration, and identifies three areas for further research: quantification of exposure, genetic susceptibility factors, and earlier detection and prevention of neuro degenerative diseases.

Brain Function Decline in Healthy Retired Athletes who Sustained their Last Sports Concussion in Early Adulthood

The finding that the P3, the CSP as well as neuropsychological and motor indices were altered more than three decades post-concussion provides evidence for the chronicity of cognitive and motor system changes consecutive to sports concussion.



Cumulative effects associated with recurrent concussion in collegiate football players: the NCAA Concussion Study.

This study suggests thatPlayers with a history of previous concussions are more likely to have future concussive injuries than those with no history; 1 in 15 players with a concussion may have additional concussions in the same playing season; and previous concussion may be associated with slower recovery of neurological function.

Epidemiology of Concussion in Collegiate and High School Football Players

Players who sustained one concussion in a season were three times more likely to sustain a second concussion in the same season compared with uninjured players, and contact with artificial turf appears to be associated with a more serious concussion than contact with natural grass.

Cumulative Effects of Concussion in High School Athletes

A more severe on-field presentation of concussion markers is evidenced in high school athletes with a pronounced history of concussion, the first to suggest a cumulative effect of concussion in highSchool athletes.

Cumulative effects of concussion in amateur athletes

This study provides preliminary evidence to suggest that athletes with multiple concussions might have cumulative effects of injury, with differences between groups in symptom reporting and memory performance.

Lower cognitive performance of older football players possessing apolipoprotein E epsilon4.

Older professional football players who possessed the APOE epsilon4 allele scored lower on cognitive tests than did players without this allele or less experienced players of any genotype, and the cognitive status of professional athletes with repeated exposure to head trauma may be influenced by age, inherited factors such as APOE genotypes, and cumulative exposure to contact.

Head injury in early adulthood and the lifetime risk of depression.

The risk of depression remains elevated for decades following head injury and seems to be highest in those who have had a severe head injury.

Alzheimer's disease after remote head injury: an incidence study.

Cox proportional hazards modelling showed that a history of head injury with loss of consiousness reported to the physician was associated with earlier onset of dementia due to Alzheimer's disease, consistent with the findings of several case-control studies suggesting that head injury may be a risk factor for Alzheimer's Disease.

The association between head trauma and Alzheimer's disease.

The relation between head trauma and Alzheimer's disease was one of four major risk factors explored in a case-control study of 130 matched pairs; cases were clinically diagnosed at two geriatric psychiatric clinics in Seattle, Washington, and controls were friends or nonblood relatives of the cases.

Head injury and the risk of AD in the MIRAGE study

The influence of head injury on the risk of AD appears to be greater among persons lacking APOE-ε4 compared with those having one or two ε4 alleles, suggesting that these risk factors may have a common biologic underpinning.

Apolipoprotein E epsilon4 associated with chronic traumatic brain injury in boxing.

Preliminary findings suggest that possession of an APOE epsilon4 allele may be associated with increased severity of chronic neurologic deficits in high-exposure boxers.
