Examine frequency, character and course of symptoms until 3 months after MTBI and the relation between symptoms and disability.
Prospective cohort study of 122 consecutive patients with MTBI. Symptom assessment after 1, 7 and 14 days and 3 months post-injury by use of Rivermead Post-concussional Questionnaire. Disability assessment by use of Rivermead Head Injury Follow-up Questionnaire.
Patients reporting one or more symptoms declined from 86% on day 1 to 49% 3 months post-injury, when 25% also reported change in one or more domains of everyday activities. Poor memory, sleep disturbance and fatigue were most commonly reported. Symptom and disability scores were correlated (tau = 0.60; p < 0.001). Early symptom load correlated with late symptom load (tau = 0.38; p < 0.01).
Symptoms gradually decline post-injury. Symptoms correlate with disability at 3 months. Patients with early high symptom load are at risk for developing persisting complaints.

    • "Recent studies have demonstrated that the influence of microstructural injury in the development of post-traumatic complaints after mTBI is debatable Waljas et al., 2015]. We included a group of patients with complaints that reported at least one complaint within the cognitive or affective domain, because these complaints are more specific for mTBI as compared to somatic com- plaints [Dischinger et al., 2009; Ettenhofer and Barry, 2012; Lundin et al., 2006; Ponsford et al., 2011] . However, posttraumatic complaints are also reported by the general population and non-head injured patients, which suggests that other factors than structural injury play a dominant role in the development of (persistent) post-traumatic complaints [Cassidy et al., 2014].

    ABSTRACT: Objectives: To assess the role of brain networks in emotion regulation and post-traumatic complaints in the sub-acute phase after non-complicated mild traumatic brain injury (mTBI). Experimental design: Fifty-four patients with mTBI (34 with and 20 without complaints) and 20 healthy controls (group-matched for age, sex, education, and handedness) were included. Resting-state fMRI was performed at four weeks post-injury. Static and dynamic functional connectivity were studied within and between the default mode, executive (frontoparietal and bilateral frontal network), and salience network. The hospital anxiety and depression scale (HADS) was used to measure anxiety (HADS-A) and depression (HADS-D). Principal observations: Regarding within-network functional connectivity, none of the selected brain networks were different between groups. Regarding between-network interactions, patients with complaints exhibited lower functional connectivity between the bilateral frontal and salience network compared to patients without complaints. In the total patient group, higher HADS-D scores were related to lower functional connectivity between the bilateral frontal network and both the right frontoparietal and salience network, and to higher connectivity between the right frontoparietal and salience network. Furthermore, whereas higher HADS-D scores were associated with lower connectivity within the parietal midline areas of the bilateral frontal network, higher HADS-A scores were related to lower connectivity within medial prefrontal areas of the bilateral frontal network. Conclusions: Functional interactions of the executive and salience networks were related to emotion regulation and complaints after mTBI, with a key role for the bilateral frontal network. These findings may have implications for future studies on the effect of psychological interventions. Hum Brain Mapp, 2016. © 2016 Wiley Periodicals, Inc.

    • "These critical illnesses can affect the patient with different levels of severity, from mild to severe. Even those patients that suffer from mild brain damage demonstrate symptoms such as headache, concentration disorders, fatigue and lack of memory (Lundin et al., 2006). This patient group needs treatment and monitoring supplied by neurosurgical intensive care even though they are conscious. "

    ABSTRACT: Aim: The aim of this study was to explore the lived experiences of conscious patients in neurosurgical intensive care. Method: Data collection was performed by qualitative interviews using an interview guide. Eleven former patients, seven women and four men, were interviewed two to 14 months after discharge. The interviews were recorded and transcribed verbatim and analysed using an interpretive phenomenological approach. Findings: The analysis revealed three themes: To feel safe in an unfamiliar situation, to experience strains and limitations, and to be confirmed as a human being. These three themes culminated in the essence: To feel strong in an unfamiliar situation. Patients experienced a soothing environment where, despite strains, they felt safe being cared for in a ward with specialised medical treatment. When mental and physical strains decreased during the period of care, they experienced the ability to cope with the simplest tasks as a sign of regained identity. Conclusion: Patients' main experience during intensive care was security. Security along with human contact and interaction with staff and next of kin made the patients feel strengthened as human beings in an unfamiliar situation. The fact that the patients were conscious enabled them to understand their situation and to experience security.

    • "The effects of TBI are wide ranging and disabling, with symptoms persisting for many years after injury, even following a mild TBI [4] [5]. The most common symptoms following a mild TBI include memory difficulties , fatigue, and poor sleep [6]. In the general population, rates of sleep problems can vary considerably based on how sleep is measured. "

    ABSTRACT: Sleep quality affects all aspects of daily functioning, and it is vital for facilitating recovery from illness and injury. Sleep commonly becomes disrupted following moderate to severe brain injury, yet little is known about the prevalence of sleep disruption over time and how it impacts on recovery following mild injury. This was a longitudinal study of 346 adults who experienced a mild brain injury (aged ≥16 years) identified within a population-based incidence sample in New Zealand. The prevalence of sleep difficulties was assessed at baseline (within two weeks), one, six and 12 months, alongside other key outcomes. One year post injury, 41.4% of people were identified as having clinically significant sleep difficulties, with 21.0% at a level indicative of insomnia. Poor sleep quality at baseline was significantly predictive of poorer post-concussion symptoms, mood, community integration, and cognitive ability one year post injury. The prevalence of insomnia following mild traumatic brain injury (TBI) was more than three times the rate found in the general population. Of those completing a sleep assessment at six and 12 months, 44.9% of the sample showed improvements in sleep quality, 16.2% remained stable, and 38.9% worsened. Screening for sleep difficulties should occur routinely following a mild brain injury to identify adults potentially at risk of poor recovery. Interventions to improve sleep are needed to facilitate recovery from injury, and to prevent persistent sleep difficulties emerging. Copyright © 2015 Elsevier B.V. All rights reserved.
