  Purpose

The purpose of this study is to find out differences in activation of mood regulating areas of the brain in response to negative and positive pictures, before and after 6 weeks of additional Wellbutrin XL treatment. Participants should have been treated for depression with an SSRI medication (e.g., Prozac, Zoloft, Paxil, Celexa or Lexapro) and have decreased depression symptoms but also be experiencing side effects of medications such as sexual side effects and feelings of apathy (indifference, lack of interest) and lack of full emotional response. We will first take a brain scan to measure activity in different parts of the brain, while subjects are seeing pictures, using Magnetic Resonance Imaging (MRI) scan. Then we will add Wellbutrin XL - another well-known antidepressant that acts by increasing the chemical dopamine in the brain, to subjects' treatment. Wellbutrin addition is useful in decreasing the sexual side effects of SSRIs. After treatment with Wellbutrin XL for 6 weeks subjects will have a second MRI scan with picture rating.

Further study details as provided by Indiana University:

Primary Outcome Measures:
  • Activation and connectivity of frontal cortex and limbic region as measured by MRI scan at baseline and six weeks from baseline
  • Improvement of scores on Apathy Evaluation Scale and Changes in Sexual Functioning Questionnaire given weekly for six weeks

Secondary Outcome Measures:
  • Improvement of scores on Hamilton Depression Rating Scale given weekly for six weeks
  • Improvement on Clinical Global Impression Severity and Improvement Scales given weekly for six weeks
  • Improvement of scores on MADRS (specifically item #8) given weekly for six weeks

Estimated Enrollment: 15
Study Start Date: July 2004
Estimated Study Completion Date: November 2007
Detailed Description:

Hypotheses:

Hypothesis 1.After wellbutrin XL addition for 6 weeks, SSRI treated subjects will show increased activation and connectivity of prefrontal cortex and limbic regions such as the amygdala on exposure to negative and positive pictures

Hypothesis 2.Increase in activation of the MRC (Mood Regulating Circuit) will correlate with decrease in Apathy Evaluation Scale (AES) score and Sexual Dysfunction Score.

We plan to study a maximum of 15 subjects in this study. SSRI treated depressed patients who after treatment of depression continue to suffer from sexual dysfunction and apathy will be included in the study. fMRI will be conducted at baseline and after addition of Wellbutrin XL treatment 300 mg po qd and then used at a dose of 300 mg - 450 mg from week 3 - 6 depending on response and tolerance. Patients will also be rated weekly on 17-item Hamilton Depression Rating Scale, Montgomery-Asberg Depression Rating Scale (MADRAS) (Montgomery and Asberg 1979), AES (Marin et al 1991), Changes in Sexual Functioning Questionnaire (CSFQ) and Clinical Global Impression (Improvement) weekly for 6 weeks. Depressed patients will also be rated on the scan days on cognitive measures such as verbal memory and working memory.

Criteria

Inclusion Criteria:

  1. Ages 18 - 60 years and able to give voluntary informed consent.
  2. Satisfy criteria for recent treatment with for Major Depressive Episode using DSM-IV episode recently treated with an adequate dose of an SSRI (sertraline, paroxetine, fluoxetine, citalopram, escitalopram) with 17-item Hamilton Depression Rating Scale (HDRS) score < 18.
  3. Complaining of symptoms of apathy, lack of feeling or sexual dysfunction with AES score < 10 and/or MADRAS item 8 (inability to feel > 1) and/or CSFQ score > 10
  4. Satisfy criteria to undergo an MRI scan based on MRI screening questionnaire. 5) Able to be managed as outpatients for initial assessment and during treatment as ascertained by the following - Symptoms not worsening by more than 10 points on the HDRS during the course of the study and not representing danger to self or others.

Exclusion Criteria:
