The chance a former football player will be diagnosed with hypertension when they retire rises in step with the number of concussions they experienced during their career. High blood pressure may be another driver of cognitive decline in conjunction with repeated TBI for football players. However, controlling blood pressure could help slow both cardiovascular and cognitive decline.
Longer career length and playing specific positions put NFL players at greater risk of developing cognitive problems and mental health issues. Playing for 10 or more seasons increased the risks for depression, anxiety, and cognitive impairment twice as much than those who played for a single season. For every five seasons of play, the risks increase 20% for cognitive impairment. Those most at risk are running backs, linebackers and those who played special teams positions.
Using data from replacement players who entered into the NFL when professionals went on strike in 1987, researchers evaluate player mortality and overall health. The findings, researchers report, may help to make the game safer for current football players.
