In the most recent short article addressing injury issues in combative sports, a study was published last month in the Journal of Neurotrauma studying cognitive impairment from boxing.
The study, titled Chronic effects of Boxing: DTI and Cognitive Findings, used Magnetic Resonance Imaging and Diffusion Tensor Imaging to study brain trauma among 10 boxers (9 active and 2 retired) and 9 other participants not involved in combative sports.
Unsurprisingly the study noted cognitive issues among the boxers and, consistent with other recent Camiseta Selección de fútbol de Senegal studies, pointed to the number of years involved in the sport, as an essential element leading to long term impairment.
To this point the study concluded “Years of boxing had the most consistent, negative correlations with FA, ranging from -0.65 for the best ventral striatum to -0.92 for the best cerebral peduncle. Years of boxing was negatively related to the number of words consistently recalled over trials (r=-.74, p=0.02), delayed recall (r=-0.83, p=0.003), and serial RT, (r=.66, p=0.05).”

We used magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI) to assess the effects of boxing on brain structure and cognition in 10 boxers (8 retired, 2 active) (mean age=45.7 years, SD=9.71) and nine participants (mean age=43.44, SD=9.11) in non-combative sports. Evans Index (maximum width of the anterior horns of the lateral ventricles/maximal width of the internal diameter of the skull) was considerably larger in the boxers, (F=4.52, p=0.050; Cohen’s f=0.531). Word list recall was impaired in the boxers ((F1,14)=10.70, p=0.006, f=0.84)) whereas implicit memory measured by faster reaction time (RT) to a repeating sequence of numbers than to a random sequence was preserved t=2.52, p<0.04. Fractional anisotropy (FA) and the obvious diffusion coefficient (ADC) measured by tractography did not considerably differ between the groups. However, DTI metrics were considerably correlated with declarative memory (e.g., left ventral striatum ADC with delayed recall, r=-0.74, p=0.02) and with RT to the repeating number sequence, (r=0.70, p=0.04) in the boxers. Years of boxing had the most consistent, negative correlations with FA, ranging from -0.65 for the best ventral striatum to -0.92 for the best cerebral peduncle. Years of boxing was negatively related to the number of words consistently recalled over trials (r=-.74, p=0.02), delayed recall (r=-0.83, p=0.003), and serial RT, (r=.66, p=0.05). We conclude that microstructural integrity of white matter tracts is related to declarative memory and reaction speed in boxers Camiseta PSV Eindhoven and to the extent of boxing exposure. Implications for chronic traumatic encephalopathy are discussed.
