NFL's long-term study on dementia seen as flawed.
The New York Times (10/27, B10, Schwarz) reports that the National Football League (NFL) "and its doctors have consistently dismissed independent studies showing unusual cognitive decline in former players," insisting that "a long-term study by the league's committee on concussions, expected to be published in several years, will be the authoritative analysis."
However, "according to many experts in epidemiology, dementia and health policy who assessed the study's design," the study "is fraught with statistical, systemic, and conflict-of-interest problems that make it inappropriate to examine the issue." Experts "contacted by The New York Times" said "their primary concern was that an improperly conducted study, should it claim no discernible cognitive decline among players, could mislead the public about the seriousness of football brain injuries."
