Researchers report that former professional soccer players show measurable changes in the brain, but do not demonstrate cognitive decline compared with similarly aged people who do not play contact sports. The study, led by researchers at Imperial College London, follows a group of 142 former soccer players aged 30 to 60. It compares them with 56 healthy participants in the same age range who have no history of contact sports. According to the reports, the researchers observe differences in brain structure and/or related imaging markers between the two groups. However, when cognitive performance is assessed, the former players do not show worse outcomes than the control group. The findings suggest that exposure to soccer-related head impacts may be associated with detectable brain changes, while not necessarily translating into observable cognitive impairment in the assessed age range. The study’s results are based on the comparison between the two groups and the cognitive and brain measures used by the research team. The reported conclusion is that brain changes are present, but cognitive decline is not evident under the study’s conditions.
