Study of Elite UK Soccer Players Finds No Significant Structural Damage Or Neuropsychological Changes From Heading During First 5 Years Of Pro Career
A new study reports no significant neurological, structural brain imaging or neuropsychological change among a sample of young elite professional soccer players in the United Kingdom over the first 5 years of their professional career. (1)
The study, reported in the journal Brain Injury, is believed by the authors to be the first longitudinal prospective study to track a group of soccer players and controls over time.
Researchers, led by Steven Kemp of the Department of Clinical and Health Psychology at St. James’ Hospital in Leeds, England, recruited thirty-two elite young professional footballers and thirty-three controls, 24 and 17 of whom were identified at follow-up, respectively. Medical examination, MRI (brain) imaging and detailed neuropsychological data were collected on the players and controls at baseline and 5-year follow-up.
All participants had normal neurological examination at both time points. At baseline, 37% of the soccer players had sustained minor neurological insults. Between baseline and 5 years, 66% of the soccer players had sustained minor neurological insults. No MRI (brain) abnormalities were identified among the players at either time point. The soccer players scored 6 points lower than the controls on IQ tests. Test–re-test analysis on a range of carefully selected neurocognitive tests revealed a picture of good stability in cognitive functioning over the 5-year period.
Despite the study’s findings, the consequences of neurological insults sustained during soccer in the form of multiple concussions and heading remains unclear.
