The crossroads of sports concussions and aging
The consequences of traumatic brain injury (TBI) are sizable in both human and economic terms. In the USA alone, about 1.7 million new injuries happen annually, making TBI the leading cause of death and disability in people younger than 35 years of age. Survivors usually exhibit lifelong disabilities involving both motor and cognitive domains, leading to an estimated annual cost of $76.5 billion in direct medical services and loss of productivity in the USA.
