Former Professional Footballers Show Midlife Brain Changes, Study Finds

London – A new study presented at the Alzheimer's Association International Conference (AAIC) in London has revealed significant findings regarding the brain health of former professional footballers. The research compared 142 former elite footballers, aged 30-60, with a control group of 56 healthy individuals who had no history of contact sports or head injuries. The results indicate that footballers in midlife reported higher levels of depression and anxiety, along with difficulties in thinking and decision-making, when compared to the control group.

MRI imaging revealed differences in brain structure between the former players and the control group. Specifically, there was a reduction in gray matter volume in several brain regions crucial for memory, attention, decision-making, and emotional regulation. While no significant differences were found in cognitive tests between the groups, the footballers reported substantially more psychiatric symptoms and self-assessed difficulties with concentration and problem-solving.

According to the study, nearly one-third (31%) of the former players met criteria for clinically significant depressive symptoms, compared to 9% in the control group. For anxiety symptoms, 42% of the footballers met the criteria, versus 25% in the control group. Researchers emphasize, however, that the findings are preliminary and require further investigation to definitively establish a causal link between repeated head impacts and the observed changes.

The findings support a growing body of evidence linking football play, particularly repeated head impacts and longer careers, to biomarkers of neural injury and an increased risk of chronic traumatic encephalopathy (CTE). The study underscores the need for long-term monitoring and additional research to better understand the effects of sports on brain health over time.
