A nationwide study of traumatic brain injuries (TBI) in Finland has found that being hospitalized with a moderate to severe TBI as an adult increases the risk of dementia later in life.

Why it matters: Traumatic brain injury is a leading cause of death and injury globally. In 2013, 2.8 million Americans went to the emergency room, were hospitalized or died from a traumatic brain injury, according to the CDC. As populations age, it's important to know the long-term consequences of brain injuries. The authors believe this is the first nationwide survey of TBI and neurodegenerative disease.
