Brain Injuries May Raise Risk of Early Death
Researchers find second head injury, suicide and assault are the main causes
While risky behavior can put people at risk for brain injury and premature death, suicide and depression after a brain injury are also concerns.
Dr. Robert Glatter, director of sports medicine and traumatic brain injury at Lenox Hill Hospital in New York City, said, "Suicide and depression are important issues in patients after a traumatic brain injury."
These patients need a support network after a traumatic brain injury "to make sure they are not falling into depression," he said.
For the study, Fazel's team collected data on more than 218,000 people born in Sweden in 1954 or after and who had suffered a traumatic brain injury between 1969 and 2009.
Among these patients, more than 11,000 died prematurely after their brain injury. Of those who died, 21.5 percent died six months or later after the injury.
The researchers compared the death rates of those with brain injury with more than 2 million people who hadn't had a brain injury and also with more than 150,000 siblings of those who had a brain injury.
The investigators found there was an increased risk of dying prematurely among patients who survived six months after a brain injury compared with those who didn't have a brain injury. The increased risk for dying remained the same for at least five years after the injury, they noted.
These patients were also at risk of early death if they had psychiatric conditions or were substance abusers, the study found.
