Traumatic brain injury (TBI) is often thought of as occurring post-traumatic stress disorder (PTSD) but research disproves this and offers conflicting opinions. According to NCATS the organization represents the interests of its four million patients.
A consensus exists among experts however in the medical community and in government that TBI is a post-traumatic disorder (PTSD). But the exact association between the two remains unclear because each study analyzed in a different way.
In a study published in the peer-reviewed journal Combat Care a team of NCATS researchers sought to quantify information related to the impact of TBI on mood and suicidal thoughts. This double-blind study is the first to use such a powerful database-approximately 70000 hospitalized victims in 11 countries with mortality rates from 0 to 44 percent-to examine suicidal thoughts after a single TBI.
Researchers at the Centers for Disease Control and Preventions Morbidity and Mortality Weekly Report (MFR) conducted the study with support from the Eric and Anne Simmons Research Institute at Massachusetts General Hospital (MGH). Sixty-four percent of the participants were female and male and the majority of the subjects were male non-Hispanic white and aged 18 to 42 years. The majority of the (66-85 percent) participants were non-Latina white Caucasian and older than 24 years.
The researchers found that suicidal thoughts existed in a greater than 50 percent increase in TBI victimized victims compared to those who did not experience a TBI. They analyzed the mean suicide time from a 24-month baseline to the most recent four-week suicide assessment. This measure was three times lower in suicide exposed individuals after a single TBI compared to those in the comparison group who did not experience a TBI.
Men with used to suicidal thoughts had a mean number of suicidal thoughts at 4 times higher and suicidal ideation at 4-times higher compared to the control group after the two-year examination ((Note: TBI has been coded as a TBI based on the most current study findings. Not included are the effects during the eight-year follow-up period.)
