Abstract

To examine the effect of age of first exposure to tackle football on CTE pathological severity and age of neurobehavioral symptom onset in tackle football players with neuropathologically-confirmed CTE. The sample included 246 tackle football players who donated their brains for neuropathological examination. 211 were diagnosed with CTE (126/211 were without comorbid neurodegenerative diseases) and 35 were without CTE. Informant interviews ascertained age of first exposure and age of cognitive and behavioral/mood symptom onset. Analyses accounted for decade and duration of play. Age of exposure was not associated with CTE pathological severity, or Alzheimer's disease or Lewy body pathology. In the 211 participants with CTE, every one year younger participants began to play tackle football predicted earlier reported cognitive symptom onset by 2.44 years (p<0.0001) and behavioral/mood symptoms by 2.50 years (p<0.0001). Age of exposure before 12 predicted earlier cognitive (p<0.0001) and behavioral/mood (p<0.0001) symptom onset by 13.39 and 13.28 years, respectively. In participants with dementia, younger age of exposure corresponded to earlier functional impairment onset. Similar effects were observed in the 126 CTE only participants. Effect sizes were comparable in participants without CTE. In this sample of deceased tackle football players, younger age of exposure to tackle football was not associated with CTE pathological severity, but predicted earlier neurobehavioral symptom onset. Youth exposure to tackle football may reduce resiliency to late life neuropathology. These findings may not generalize to the broader tackle football population and informant-report may have affected the accuracy of the estimated effects. This article is protected by copyright.

Attention Score in Context

This research output has an Altmetric Attention Score of 713. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 31 March 2021.
All research outputs
#14,861
of 17,606,952 outputs
Outputs from Annals of Neurology
#7
of 4,688 outputs
Outputs of similar age
#501
of 285,141 outputs
Outputs of similar age from Annals of Neurology
#1
of 51 outputs
Altmetric has tracked 17,606,952 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 99th percentile: it's in the top 5% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 4,688 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 13.5. This one has done particularly well, scoring higher than 99% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 285,141 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 99% of its contemporaries.
We're also able to compare this research output to 51 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 98% of its contemporaries.
