Some 13% of older adults are diagnosed with traumatic brain injury (TBI), according to a new study. These injuries are typically caused by falls from ground level.

Some 13% of older adults are diagnosed with traumatic brain injury , according to a new study. These injuries are typically caused by falls from ground level. Researchers followed about 9,200 Medicare enrollees, whose average age was 75 at the start of the study, and found that contrary to other studies of younger people, being female, white, healthier and wealthier was associated with higher risk of TBI.

While TBI can be successfully treated, these injuries increase the likelihood of a number of serious conditions, including dementia, Parkinson's disease and seizures, as well as cardiovascular disease and psychiatric conditions like depression and anxiety. Earlier TBI studies have found that males, non-whites and those of lower socio-economic status were more likely to be diagnosed with TBI. But the current study found that females and whites were overrepresented among the 1,148 participants with TBI. While 58% of the HRS participants were female and 84% were white, among those with TBI, the figures were 64% and 89%. In addition, 31% of those with TBI were in the highest quartile of wealth, while 22% were in the lowest.

But the findings may mask the true incidence of injury, since the data only reflect cases of TBI in which patients were diagnosed and received care. A 2007 study found that 42% of respondents to an online survey did not seek medical attention after TBI. "The overall evidence still overwhelmingly sides with physical activity being neuroprotective," said Gardner, who is now at the Sheba Medical Center in Israel."However, taking measures to optimize safety and mitigate falls is critical. These measures need to change over the life-course as an individual accumulates physical or cognitive disabilities, or both."Chicago
