Specific markers of damage to the white matter of the brain, called white matter hyperintensity, can be seen on brain scans. According to a new study, brain scans performed during the lifetime of athletes in contact sports show that high white matter signals are associated with neuropathological changes compared to changes in the brain at autopsy. I showed that. This survey was published in the online version on November 24, 2021. Neurology, American Academy of Neurology Medical Journal. The study found that white matter hyperintensity is more common in athletes who have played contact sports for longer or have had a head impact during their career.
The white matter hyperintensity is the area that looks bright on magnetic resonance imaging (MRI) scans.They are more common to people as they get older Medical condition favorite High blood pressure..
“Our results are exciting because they show that. White matter hyperintensity May cause long-term harm to brain “In people with a history of repetitive head effects,” said Dr. Michael Arosco, a research author at Boston University School of Medicine, “white matter hyperintensity for MRI is a repetitive head effect. It could be an effective tool for studying. It affects the white matter of the brain while the athlete is still alive. “
The study involved 75 people who repeatedly shocked their heads and reported symptoms. This included 67 soccer players and 8 other players. Contact sports Like soccer, boxing, or military veterans. Of the soccer players each played for an average of 12 years, 16 athletes played professionally and 11 played semi-professional.
Everyone donated their brains to postmortem research to advance the study of the long-term effects of repeated head shocks. The researchers then examined medical records, including scans made while the athlete was still alive. Participants performed brain scans on average at age 62. The average age of athletes at the time of death was 67 years.
Of the participants, 64% were determined to have dementia prior to death. This was decided by discussions with their loved ones. Autopsy showed that 53 (71%) had chronic traumatic encephalopathy (CTE). CTE is a neurodegenerative disorder associated with repetitive head impacts, including those from football, which can progress to dementia.
After investigating Brain scanResearchers have approximately twice the probability of having more severe microvascular disease and other indicators of white matter damage, and three times the probability of having more severe tau accumulation, for each unit of high signal content in white matter. I found that there is. Frontal lobe of the brain. Tau protein accumulation in the brain is a biomarker for advanced brain diseases such as Alzheimer’s disease and CTE. Researchers have also found that the greater the amount of white matter high signal, the longer the number of years of playing soccer.
When it comes to completing daily tasks, White matter The hyperintensity was associated with a higher score on the questionnaire regarding the performance of daily tasks completed by the caregiver of the brain donor.
“There are significant limitations to this study, and more research is needed to identify the inherent risk factors and causes of these brain lesions in people with a history of repeated head shocks,” Arosco said. Stated.
The limits of the study included the use of MRI obtained for clinical purposes rather than research purposes, and participants were predominantly elderly, symptomatic, male, and ex-American. soccer player..
