Differences in duration contact/collision sport (LEFT) and American football (RIGHT) participation between Healthy Controls (N = 41) and FTD/PPA (N = 40) reporting at least 1 year of play (i.e., not including those who never participated). The dashed line represents the minimum duration of participation (1 year). Duration of contact/collision sport exposure was longer in FTD/PPA than HC (8.5 ± 6.7yrs vs. 5.3 ± 4.5yrs, p = .008). For American football, participants with FTD/PPA played about twice as long as HC (6.2yrs ± 4.3yrs vs. 3.1 ± 2.4yrs; p = .003)
