A different take on previous information regarding the prevalence of chronic brain damage in retired NFL players is being proposed by researchers. Researchers performed in-depth neurological examinations of 45 retired NFL players, ranging in age from 30-to 60-years old. "Our results indicated that there were brain lesions and cognitive impairments in some of the players; however the majority of the individuals in our study had no clinical signs of chronic brain damage to the degree that has been noted in previous studies," said the lead author.
