Each year, around 2 million Americans experience a sport-related traumatic brain injury (TBI). Soldiers are also at elevated risk for TBI; 17% of deployed soldiers to Iraq experienced a TBI, and among them, 59% experienced multiple TBIs. On a less overt level, our stress levels are on the rise. And to make matters worse, there’s a direct link between stress and increased risk for cardiovascular effects like heart attack and stroke. Both brain injury and cardiovascular events elevate risk for age-related brain disease like dementia.
