abstract="OBJECTIVES: We assessed whether mild traumatic brain injury (mTBI) reported by UK service personnel between 2007 and 2009 was associated with postconcussion symptoms (PCS) 7 to 8 years later.  SETTING: United Kingdom.  PARTICIPANTS: A total of 4601 service personnel all of whom had deployed to Iraq and/or Afghanistan. <br><br>DESIGN: Longitudinal study.  MAIN OUTCOME MEASURES: Nine PCS reported in a survey carried out between 2014 and 2016. The main independent variable was mTBI reported between 2007 and 2009. <br><br>RESULTS: A total of 2318 (50.4%) out of 4601 participants completed the follow-up questionnaire. Mild traumatic brain injury was associated with 2 of 9 PCS. Mild traumatic brain injury at baseline was associated with dizziness at follow-up in the fully adjusted model, in comparison with either &quot;other injury&quot; or &quot;no injury&quot; group. Mild traumatic brain injury was associated with loss of concentration in comparison with &quot;no injury&quot; but in comparison with the &quot;other injury&quot; group, it was not in the fully adjusted model. The prevalence of 7 of the 9 PCS increased over time regardless of mTBI status. <br><br>CONCLUSIONS: Mild traumatic brain injury reported in 2007-2009 was associated with dizziness and possibly with loss of concentration 7 years later but not with most PCS. The prevalence of most PCS increased over time independently of mTBI.<p /> <p>Language: en</p>",
