A study by Columbia University researchers found that playing football regularly for two years can cause deterioration in memory and thinking skills. In this respect reports Daily mail.
To determine the link between playing football and increased risk of dementia, scientists examined changes in the brains of 148 recreational players using magnetic resonance imaging and diffusion tensor imaging (which analyzes anatomical connections in the brain through a detailed assessment of the structure of white matter). . Participants were also asked to take cognitive ability tests. Players also reported how often they trained and in what situations they headed the ball.
It turned out that volunteers who frequently played football showed significant changes in the frontal regions of the brain associated with memory and learning. Most likely, such conversions occurred as a result of frequent heading of the ball. The scientists also noted that high levels of ball control were associated with decreased effectiveness in learning verbal speech. Taken together, these changes indicate an increased likelihood of developing dementia.
