    Depression in the first year after traumatic brain injury
    (Neurotrauma Society, 2018-07-15) Laviolette, Valérie; Ouellet, Marie-Christine; Roy, Joanne.; Turgeon-Fournier, Alexis; Moore, Lynne; Savard, Josée; Swaine, Bonnie; Beaulieu-Bonneau, Simon.; Sirois, Marie-Josée; Giguère, Myriam
    The aims of this study were to document the frequency of major and minor depressive episodes in the first year after traumatic brain injury (TBI), taking into account TBI severity and pre-morbid history of major depression, and to describe trajectories of depressive episodes. Participants were 227 adults who were hospitalized post-TBI (76% male; mean age = 41 years; 50% mild, 33% moderate, and 17% severe TBI). Major and minor depressive episodes were assessed with the Mini International Neuropsychiatric Interview at three time points (4, 8, and 12 months after TBI). Overall, 29% of participants had a major depressive episode in at least one of the three assessments, with fairly stable rates across assessments. Participants with mild TBI were more likely than those with moderate/severe TBI to be diagnosed with major depression, as were individuals with a positive pre-morbid history of depression compared to those without such history. In addition, 13% of participants had a minor depressive episode in at least one of the three assessments. Rates of minor depression significantly decreased from 4 to 8–12 months post-injury. Results also revealed a wide variety of trajectories of depressive episodes across assessments. Of note, 52% of major depression cases still fulfilled diagnostic criteria 4 months later, whereas 38% of minor depression cases deteriorated to major depression at the following assessment. These findings suggest that depression is highly prevalent after TBI, and monitoring of patients with subthreshold depressive symptoms is warranted in order to prevent the development of full-blown major depressive episodes.

    Anxiety symptoms and disorders in the first year after sustaining mild traumatic brain injury
    (Springer, 2021-11-29) Ouellet, Marie-Christine; Tessier, Danielle; Lamontagne, Guillaume; Souesme, Guillaume; Savard, Josée; Belleville, Geneviève; Le Sage, Natalie; Sirois, Marie-Josée; Giguère, Myriam; Beaulieu-Bonneau, Simon.
    Purpose/objective: The goals of the present study were (a) to document the prevalence of anxiety-related disorders and anxiety symptoms at 4, 8, and 12 months postinjury in individuals with mild traumatic brain injury (mTBI) while considering preinjury history of anxiety disorders and (b) to verify whether the presence of anxiety in the first months after mTBI was associated with more symptoms present 1 year after the injury. Research Method/Design: One hundred and twenty participants hospitalized after an accident and having sustained mTBI were assessed at 4, 8, and 12 months postaccident with the Mini-International Neuropsychiatric Interview, the Hospital Anxiety and Depression Scale, and questionnaires assessing fatigue, irritability, perceived stress, cognitive difficulties, depression, insomnia, and pain. Results: At 4 months, 23.8% of participants presented with at least one anxiety-related disorder compared with 15.2% at 8 months and 11.2% at 12 months. Overall, 32.5% presented with at least one anxiety disorder over the first 12 months post-mTBI. Participants with a history of anxiety (20.5%) were significantly more anxious after their accident. Individuals who were anxious 4 months after the accident presented with more symptoms in different areas 12 months postinjury compared with nonanxious individuals. Conclusions/implications: The present results highlight that anxiety should be evaluated and managed carefully as it appears to be a key factor in the persistence of other mTBI-related symptoms.

    Fatigue in the first year after traumatic brain injury : course, relationship with injury severity, and correlates
    (Lawrence Erlbaum, 2016-04-01) Ouellet, Marie-Christine; Beaulieu-Bonneau, Simon.
    The objectives of this study were to document the evolution of fatigue in the first year after traumatic brain injury (TBI), and to explore correlates of fatigue. Participants were 210 adults who were hospitalised following a TBI. They completed questionnaires 4, 8, and 12 months post-injury, including the Multidimensional Fatigue Inventory (MFI). Participants with severe TBI presented greater mental and physical fatigue, and reduced activity compared to participants with moderate TBI. For all MFI subscales except reduced motivation, the general pattern was a reduction of fatigue levels over time after mild TBI, an increase of fatigue after severe TBI, and stable fatigue after moderate TBI. Fatigue was significantly associated with depression, insomnia, cognitive difficulties, and pain at 4 months; the same variables and work status at 8 months; and depression, insomnia, cognitive difficulties, and work status at 12 months. These findings suggest that injury severity could have an impact on the course of fatigue in the first year post-TBI. Depression, insomnia, and cognitive difficulties remain strong correlates of fatigue, while for pain and work status the association with fatigue evolves over time. This could influence the development of intervention strategies for fatigue, implemented at specific times for each severity subgroup.
