To the Editor: The recent article by Dr Matser
and colleagues1 on neuropsychological impairment
among amateur soccer players has been interpreted in some media reports as
demonstrating that "heading" the ball may lead to brain damage. While this
conclusion does not seem to have been suggested by the authors, we have 3
additional questions about the internal and external validity of this study.
