Objective: To characterize the long-term consequences of mild traumatic brain
injury regarding post-concussion symptoms, post-traumatic stress, and quality of
life; and to investigate differences between men and women. Design: Retrospective
mixed-methods study. Subjects/patients and methods: Of 214 patients with mild
traumatic brain injury seeking acute care, 163 answered questionnaires concerning
post-concussion symptoms (Rivermead Post-Concussion Symptoms Questionnaire; RPQ),
post-traumatic stress (Impact of Event Scale; IES), and quality of life (Short
Form Health Survey; SF-36) 3 years post-injury. A total of 21 patients underwent
a medical examination in connection with the survey. The patients were contacted
11 years later, and 10 were interviewed. Interview data were analysed with
content analysis. Results: The mean total RPQ score was 12.7 (standard deviation;
SD 12.9); 10.5 (SD 11.9) for men and 15.9 (SD 13.8) for women (p = 0.006). The 5
most common symptoms were fatigue (53.4%), poor memory (52.5%), headache (50.9%),
frustration (47.9%) and depression (47.2%). The mean total IES score was 9.6 (SD
12.9) 7.1 (SD 10.3) for men and 13.0 (SD 15.2) for women (p = 0.004). In general,
the studied population had low scores on the Short Form Health Survey (SF-36).
The interviews revealed that some patients still had disabling post-concussion
symptoms and consequences in many areas of life 11 years after the injury event.
Conclusion: Long-term consequences were present for approximately 50% of the
patients 3 years after mild traumatic brain injury and were also reported 11
years after mild traumatic brain injury. This needs to be taken into account by
healthcare professionals and society in general when dealing with people who have
undergone mild traumatic brain injury.
