Study on veterans suggests that mild traumatic brain injury may increase the risk of dementia



The study was released just weeks after another study with US veterans linked mild TBIs to an increased risk of Parkinson's disease.

After weeks, the researchers had assumed that even mild craniocerebral injury (TBIs) could lead to a higher one In a second study with US veterans, it is now suggested that these brain injuries, minor as they may be, increase the risk of dementia.

According to a report from the Los Angeles Times

it has long been recognized that moderate and severe TBIs are associated with a higher risk of dementia and Alzheimer's disease, and a higher likelihood of developing both diseases early , At the time of these studies, it was still unclear whether mild TBIs increased the risk of these diseases. But the new study, published in the journal JAMA Neurology this week, suggests that even milder forms of traumatic brain injury can have more serious consequences for veteran years.

The researchers took a look at the medical records of more than 350,000 veterans who had previously fought in Iraq and Afghanistan, and found that male and female veterans who had suffered at least one slight TBI experienced more than that Having had double risk of developing dementia after retirement has not suffered any brain injuries. This was based on information from two government databases that identified nearly 1

80,000 patients diagnosed with mild to severe traumatic brain injury between 2001 and 2014 by the Veterans Health Administration (VHA)

. region / stern / magazin / … 3 / index.html In the databases, researchers matched veterans with their colleagues, who also had records of VHA but did not diagnose any form of TBI. Approximately 6.1 percent of veterans in the TBI group suffered from dementia within an average of 3.6 years after the injury, while only 2.6 percent of those in the non-TBI control group had the disease within an average period of 4.8 Developed years ago. Researchers then adjusted various variables, such as age, psychiatric conditions and history, to find that those with mild TBIs had at least 2.36 times more dementia than veterans in the control group, with the risk varying according to Whether the person was losing consciousness or not following the injury

Of the injured veterans identified from the government databases, about 10 percent of veterans suffered from mild TBIs and did not lose consciousness of injuries, while another 13 percent lost consciousness for 30 minutes or less after a slight TBI. Thirty-one percent of these veterans were diagnosed with mild TBIs, with medical records that do not indicate whether they have lost consciousness or not. The remaining 46 percent had either moderate or severe TBIs.

The Los Angeles Times noted that the findings are a major concern when 15 to 20 percent of the veterans who fought in Operation Enduring suffered freedom and Operation Iraqi Freedom at least one mild traumatic brain injury, with multiple mild TBIs on the agenda and the risk of dementia increasing with the severity of brain injury. According to the study's first author, Deborah Barnes of the San Francisco Veterans Affairs Health Care System, veterans with moderate or severe TBIs had nearly four times the chance of developing dementia during the study period than the control group members.

The New Study About two weeks after another research team gathered data from VHA databases and analyzed more than 320,000 US military veteran records to find a link between TBIs and Parkinson's disease. According to an earlier report by Inquisitr about half of veterans were diagnosed with light to severe craniocerebral injury during their lifetime. While the proportion of Parkinson's patients was low, previous TBI patients were 56 percent more likely than those who remained healthy.
