Brief summary:
The purpose of this study is to examine the efficacy of sertraline to prevent the onset of mood and anxiety disorders during the first six months after traumatic brain injury.

Detailed description:
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.

Arms:
arm 1: Placebo will be given in a double blind fashion via an equal number of tablets (identical to the sertraline tablets) administered once daily. arm 2: Sertraline will be given in a double blind fashion via tablets administered once daily. Once stabilized in the targeted dosage (100 mg per day), sertraline serum levels will be monitored twice during the course of the intervention.

Interventions: intervention 1: Placebo intervention 2: Sertraline
Intervention descriptions: intervention 1: an inactive substance intervention 2: Sertraline and placebo will be given in a double blind fashion via an equal number of identical tablets administered once daily. Once stabilized in the targeted dosage (100 mg per day), sertraline serum levels will be monitored twice during the course of the intervention. Blood samples will be obtained randomly, one during the first and one during the second trimesters of the protocol.
