Scientists came to these conclusions after analysing the health data of 56 former rugby players, as well as brain scans. Thirty of the athletes who had suffered at least five concussions were found to have high levels of total tau and phosphorylated tau 181 proteins, as well as high levels of beta-amyloid. The remaining 26 did not have these levels.
These compounds are the basis of neurodegeneration and pathologies such as Parkinson’s and Alzheimer’s diseases. As mentioned, the indicators cannot be said to be significant, but when they are taken into account, the probability of developing these diseases with age increases exponentially as we age.
