Detaljert beskrivelse

Traumatic brain injury (TBI) is a leading cause of death and disability among young adults. Mood disorders are the most frequent psychiatric complication of TBI, and have a large impact on family functioning, interpersonal relationships, and ability to return to work or school. Furthermore, a significant proportion of these disorders will progress to more chronic and treatment refractory forms. In spite of their clinical relevance, mood and anxiety disorders remain largely unrecognized and not adequately treated, contributing to greater disability and decreased participation in the aftermath of TBI.

The goals of this study are to learn more about how people recover from brain injury and to evaluate the effect of sertraline (also known as Zoloft) compared to placebo (an inactive substance) in preventing the occurrence of emotional and behavioral problems-such as depression, lack of motivation, anxiety, irritability or aggressive outbursts-following TBI.

In the study, a group of 104 participants with TBI-recruited immediately after resolution of posttraumatic amnesia-will be randomly assigned to receive six months of double-blind treatment with sertraline or placebo.

This study will determine how these emotional and behavioral problems influence thinking, physical recovery, and return to a productive life six months after brain injury. Researchers will also determine if certain brain changes can predict the occurrence of behavioral problems and if treatment with sertraline can prevent them. Additionally, the researchers will examine the effect of sertraline on frequent post-TBI behavioral disorders such as aggression, impulsivity, poor decision making and apathetic symptoms.

Magnetic resonance imaging (MRI)-based volumetry and diffusion tensor imaging will be used to examine the structural correlates of mood and anxiety disorders and to evaluate them as biological predictors of treatment response and community reintegration. The researchers hypothesize that early preventive treatment with sertraline will reduce mood and behavioral symptoms, prevent the occurrence of structural and functional brain changes associated with the onset of mood disorders, increase access to and participation in rehabilitation programs for TBI, and, consequently, improve psychosocial outcome.

Tidsramme
Time to Onset of Diagnostic and Statistical Manual (DSM) IV Defined Mood and Anxiety Disorders Associated With Traumatic Brain Injury (TBI)
Tidsramme: 6 months after TBI

Following the DSM-IV (now updated by the DSM-5), depressive disorders associated with TBI are categorized as Mood Disorder Due to Another Medical Condition with subtypes: 1) With major depressive-like episode (if the full criteria for a major depressive episode [MDE] are met) or 2) With depressive features (prominent depressed mood but full criteria for a MDE are not met); and 3) with mixed features (e.g. significant irritability, pressured speech and formal thought disorder).

On the other hand, bipolar and related disorders due to TBI are subdivided in: 1) with manic or hypomanic like episode; 2) with manic features; and 3) with mixed features.

A similar conceptual framework has been used to define Anxiety Disorder due to another Medical Condition, in this case, TBI. According to DSM-IV/DSM-5, such diagnosis can be made when, besides an evident pathophysiological relationship with TBI, panic attacks or generalized anxiety are the prominent features of the clinical presentation.

Tidsramme
Total Community Integration Questionnaire Scores
Tidsramme: 6 months after TBI
The Community Integration Questionnaire (CIQ) is intended as a brief, reliable measure of an individual's level of integration into the home and community following traumatic brain injury. Total CIQ scores were used as the outcome measure. Range: 0 to 25. Higher scores indicate higher levels of integration into the home and community following TBI.
6 months after TBI
Iowa Gambling Task Score
Tidsramme: 6 months after TBI
The Iowa Gambling Task (IGT) evaluates decision making ability. During IGT subjects have to choose between decks of cards which yield high immediate gain but larger future loss (i.e., long term loss), and decks which yield lower immediate gain but a smaller future loss (i.e., a long term gain). The task consists of four decks of cards: A, B, C, and D. The goal in the task is to maximize profit. Subjects are required to make a series of card selections. The decks A and B are long term loss decks and the decks C and D are long term gain decks. The IGT Score reported is the combination of the raw score for each deck combined in the following way: (C+D) - (A+B). The range for this score is: -100 to 100. Higher values of this score indicate better decision making ability.

Memory Function Composite
Tidsramme: 6 months following traumatic brain injury
This outcome measures memory function and is a composite of five standardized scores: Brief Visuospatial Memory Test - Revised, Delayed Recall and California Verbal Learning Test, Short Delay Free Recall Number Correct and Discriminability, and Long Delay Free Recall Number Correct and Discriminability. Standardized scores (i.e., z-scores) for each test of this composite were obtained by subtracting the mean raw score of all participants to the raw score of each participant and dividing the result by the standard deviation of the raw scores of all participants. The composite score was obtained by averaging the z-scores of the four memory tests mentioned previously. Range: -3 to 3. Higher scores represent better memory function.

Social Functioning Examination Total Score
Tidsramme: 6 months after TBI
The Social Functioning Examination (SFE) is a semi-structured interview that measures social functioning in areas such as interpersonal relationships, work adjustment, use of community resources and satisfaction with living environment. Range: 0 to 1. Higher scores denote lower levels of social functioning.

Neuroimaging Variables (i.e., Fractional Anisotropy [FA] of Frontal White Matter Such as the Cingulate Gyrus)
Tidsramme: Baseline

FA is a measured obtained from Diffusion Tensor Imaging, an image modality of Magnetic Resonance Imaging (MRI). FA is a unitless index. Range: 0 to 1. FA describes the degree of anisotropy of a diffusion process. A value of zero means that diffusion is unrestricted or equally restricted in all directions. A value of one means that diffusion occurs only along one axis and is fully restricted along all other directions. In the context of this study, FA measures the integrity of the cingulate gyrus white matter. Higher FA values reflect higher integrity of the cingulate gyrus white matter tract. Average FA values for the right and left cingulate gyri were summed.

One aim of this project was to identify predictors of the occurrence of mood disturbances during the first 6 months following TBI. The hypothesis for this aim was that patients who develop a mood or anxiety disorder six months after TBI present at baseline with lower FA of the cingulate gyrus than those who do not.
