Retired NFL players are reporting neurocognitive deficits. Some have pathological changes consistent with CTE.
A prospective analysis was conducted including neurological history/examination, extensive neuropsychological evaluation, and Conventional/Advanced neuroimaging studies including DTI MRI in 40 retired NFL players. Individuals with fractional anisotropy (FA) values 2.5 standard deviations below aged matched controls were considered to have a positive study.
Mean age was 35.85 (range 27-56 years). They played an average of 7 years (range 2-17) in the NFL and reported an average of 8.1 concussions. Twelve (31%) reported numerous sub-concussive hits. All had normal neurological exams. Mean MMSE score was 27.3 range (16-30), CDR scale was 0.5, (max was 1.0). Seventeen (42.5%) players had positive DTI MRI’s. Twelve (30%) demonstrated evidence of traumatic axonal injury on conventional MRI. Neuropsychological testing demonstrated significant abnormalities in attention and concentration (42%), executive function (50%), learning/memory (44.7%), spatial/perceptual function (23.7%). There was a correlation with number of years played and positive DTI (p=0.0491). No correlation was found between years played and positive conventional MRI. There was no correlation between # of concussions and positive DTI, An inverse correlation was found between number of years played and # of concussions
Preliminary results of this ongoing study demonstrate a significantly higher incidence of TBI in retired NFL players when compared to the general population. Longer careers place the athlete at significantly higher risk of TBI.
