Metacognitive therapy for people experiencing persistent post-concussion symptoms following mild traumatic brain injury: a preliminary multiple case-series study

After mild traumatic brain injury (mTBI), a subgroup of individuals experiences persistent post-concussion symptoms (PPCS) that include headaches, cognitive difficulties, and fatigue. The aim of this preliminary study was to investigate possible effects associated with Metacognitive Therapy (MCT) on PPCS, maladaptive coping strategies, and positive- and negative metacognitive beliefs, following mTBI. A pre-post design supplemented with single case series repeated measurement of potential mechanisms using an A-B replication was used. From the nine participants who received MCT, all experienced a decrease in PPCS, which constituted a reliable improvement for eight participants. For eight participants (we could calculate effect sizes for eight out of nine participants) moderate to very large decreases in maladaptive coping styles and positive- and negative metacognitive beliefs were observed. However, based on visual analyses participants 6, 8, and 9 show a downward baseline trend regarding MCT mechanisms that may have persisted into the intervention phase. No adverse events were reported. In conclusion, MCT was associated with improvements in PPCS and unhelpful psychological mechanisms, but caution is required in interpreting this association. Future research, using formal single-case replication on symptom measures and randomized controlled trials appears to be justified

Frequency and predictors of headache in the first 12 months after traumatic brain injury: results from CENTER-TBI

Background: Headache is a prevalent and debilitating symptom following traumatic brain injury (TBI). Large-scale, prospective cohort studies are needed to establish long-term headache prevalence and associated factors after TBI. This study aimed to assess the frequency and severity of headache after TBI and determine whether sociodemographic factors, injury severity characteristics, and pre- and post-injury comorbidities predicted changes in headache frequency and severity during the first 12 months after injury. Methods: A large patient sample from the Collaborative European NeuroTrauma Effectiveness Research in Traumatic Brain Injury (CENTER-TBI) prospective observational cohort study was used. Patients were stratified based on their clinical care pathway: admitted to an emergency room (ER), a ward (ADM) or an intensive care unit (ICU) in the acute phase. Headache was assessed using a single item from the Rivermead Post-Concussion Symptoms Questionnaire measured at baseline, 3, 6 and 12 months after injury. Mixed-effect logistic regression analyses were applied to investigate changes in headache frequency and associated predictors. Results: A total of 2,291 patients responded to the headache item at baseline. At study enrolment, 59.3% of patients reported acute headache, with similar frequencies across all strata. Female patients and those aged up to 40 years reported a higher frequency of headache at baseline compared to males and older adults. The frequency of severe headache was highest in patients admitted to the ICU. The frequency of headache in the ER stratum decreased substantially from baseline to 3 months and remained from 3 to 6 months. Similar trajectory trends were observed in the ICU and ADM strata across 12 months. Younger age, more severe TBI, fatigue, neck pain and vision problems were among the predictors of more severe headache over time. More than 25% of patients experienced headache at 12 months after injury. Conclusions: Headache is a common symptom after TBI, especially in female and younger patients. It typically decreases in the first 3 months before stabilising. However, more than a quarter of patients still experienced headache at 12 months after injury. Translational research is needed to advance the clinical decision-making process and improve targeted medical treatment for headache. Trial registration: ClinicalTrials.gov NCT02210221.</p
