Traumatic Brain Injury Does Not Increase Risk of Dementia, According to New Study Led by a Mount Sinai Researcher

A history of traumatic brain injury (TBI) with loss of consciousness (LOC) is not associated with an elevated risk for developing dementia or Alzheimer’s Disease, according to a study led by a resesarcher at the Icahn School of Medicine at Mount Sinai. But recent TBI with LOC sustained in older adulthood is associated with an increased risk for mortality.

New York, NY (PRWEB) December 26, 2012

A history of traumatic brain injury (TBI) with loss of consciousness (LOC) is not associated with an elevated risk for developing dementia or Alzheimer’s Disease, according to a study led by a researcher at the Icahn School of Medicine at Mount Sinai. But recent TBI with LOC sustained in older adulthood is associated with an increased risk for mortality.

The research paper, titled “Risk for Late-life Re-injury, Dementia and Death Among Individuals with Traumatic Brain Injury,” was published November 21 in the Journal of Neurology, Neurosurgery & Psychiatry.

“There is a lot of conflicting information in the literature about the link between TBI and dementia. The findings from this study do not support the commonly held belief that TBI leads to dementia,” said Kristen Dams-O’Connor, PhD, first author of the study and an Assistant Professor of Rehabilitation Medicine at the Icahn School of Medicine at Mount Sinai.

Adults aged 65 or more who have had TBI with LOC at any time in their lives have a higher risk for subsequent re-injury, according to the study. This is the first study to look at the risk of re-injury among older adults. Researchers also found an increased risk for mortality, among older adults who report a recent TBI with LOC.

“The increased risk of re-injury in older adults as well as a link between recent TBI and mortality underscores the need for effective strategies to prevent injuries and re-injuries in this population, ”said Dr. Dams-O’Connor, who is also a psychologist.
