fMRI Study of Treatment Changes in Major Depression

fMRI Studies of Emotional Circuitry in Major Depression: Treatment Changes

The overall purposes of this research are to determine if Cognitive Behavioral Therapy (CBT) has the same healing effect on the brain for people with depression as traditional antidepressants do, and in comparison to healthy controls with no history of depression, to find out more about the causes of depression including differences in the extent of problems caused by depression. We hypothesize that CBT will have the same healing effect on the brain as antidepressants; that differences in brain activations created by the various tasks and genetic differences will help us understand differences in the type and severity of symptoms among the depressed subjects.

Detailed Description

The overall purposes of this research are to determine if Cognitive Behavioral Therapy (CBT) has the same healing effect on the brain for people with depression as traditional antidepressants do, to find out more about the causes of depression and why people differ in the extent of problems caused by depression, and to determine if certain differences in genes within populations are related to clinical symptoms.Genes we are examining for this study are COMT, BDNF, and 5-HTT long arm and short arm, as well as future genes that may be discovered to play a role in depression at a later time, and will be determined by examining saliva and blood samples. We are primarily studying depression by functional Magnetic Resonance Imaging (fMRI) which allows us to identify certain parts of the brain that show how the brain works in controlling negative feelings. Participants will be imaged while performing different tasks that are believed to activate emotional circuitry of the brain. Comparisons of activation patterns across these tasks will be used to characterize the cognitive mechanisms supported by different cortical regions, and to determine patterns of functional brain deficits in subjects with depression. Comparisons will also be made between changes that occur after treatment with an approved antidepressant and treatment with CBT.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Depressed Group: CBT; Depressed participants randomized to receive Cognitive Behavioral Therapy (CBT) for treatment. A fMRI scan session will occur immediately prior to starting treatment, and their second fMRI scan will occur immediately following the completion of 12 weeks of therapy.	Behavioral: Cognitive Behavioral Therapy; Depressed participants will be randomized to SRT or CBT treatment. For those in the CBT treatment condition, visits for the CBT sessions will occur on or about Day = 3,Day = 7,Day = 10,Day 14, Day 21, Day 28, Day 35, Day 42, Day 49, Day 56, Day 63, Day 70, Day 77, and Day 84. Visits to check for progress and administer the Hamilton Depression rating scale will occur at Day = 0 and on or about Day = 14, Day 28, Day 42, Day 56, Day 70 and Day 84. Depressed subjects will start their CBT treatment once their first MRI and computer testing sessions are completed.; Other Names: CBT
No Intervention: Healthy Control Group; Healthy controls will an fMRI scan session and their second fMRI scan session will occur approximately 12 weeks after.
Active Comparator: Depressed Group: SRT; Depressed participants randomized to receive the antidepressant sertraline (SRT) for treatment. A fMRI scan session will occur immediately prior to starting treatment, and their second fMRI scan will occur immediately following the completion of 12 weeks of therapy.	Drug: Sertraline; Depressed participants will be randomized to SRT or CBT treatment. For those in the SRT treatment condition, visits will involve dispensing medications, checking for side effects and administering the Hamilton Depression rating scale occurring at Day = 0 and on or about Day = 14, Day 28, Day 42, Day 56, Day 70 and Day 84. Depressed patients treated with SRT will titrate up to a maximum dose of 200 mg daily depending on tolerability and inadequate antidepressant response. Depressed subjects will start their SRT treatment once their first MRI and computer testing sessions are completed.; Other Names: SRT

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Blood Oxygen-level Dependent Activations During an Emotional Distractor Task Between fMRI Scans of Depressed Participants in the CBT Group and Control Participants.	MRI imaging was completed on 50 participants (26 depressed who were randomized to the CBT group and 24 controls) for this analysis, including fMRI scans to evaluate regional brain activation in depression during an emotional distractor task. Image data from their baseline visit was processed and analyzed to show differences in blood oxygen-level dependent (BOLD) activations between depressed participants in the CBT group and control participants in a priori regions (amygdala and dorsolateral prefrontal cortex) during the task. The specified regions were masked on the images, and voxel-wise comparisons (ANOVAs) were performed to determine differences in activations between groups within these masked regions Positive values reflect a BOLD activation in that region; negative reflects a BOLD de-activation in that region.	baseline visit and 8-week follow-up
Hamilton Depression Rating Scale Score at Baseline and 12 Weeks	The patient was rated by a research team member among 17 dimensions/items pertaining to depression symptoms experienced over the last week. Each item is scored from 0 (=absent), up to 2 or 4 (depending on the item). The maximum total score on the assessment, indicating the most severe depression, would be 52. A total score of 0-7 is considered to be normal. Total scores of 20 or higher indicate moderate, severe, or very severe depression. A 50% or greater drop in Hamilton Depression Rating Scale signifies response to treatment.	Baseline and 12 weeks
