Subjects with major depression will be evaluated and intensively characterized through questionnaires, computerized cognitive evaluation and laboratory investigations. Magnetic resonance imaging will be used to document baseline white matter structure. subjects will then receive desvenlafaxine which will be adjusted as clinically indicated. After 16 weeks the evaluations will be repeated.

Further study details as provided by Centre de recherche Fernand-Seguin, Hôpital Louis-H. Lafontaine:

Primary Outcome Measures:
  • Anisotropy [ Time Frame: 16 weeks ]
    Degree of anisotropy will be measured at baseline and 16 weeks and correlated to remission status

Secondary Outcome Measures:
  • cognitive measures [ Time Frame: 16 weeks ]
    cognitive deficits will be measured at baseline and 16 weeks and correlated to anisotropy using computerized neuropsychological testing of memory, speed and executive function.

  • Pain threshold [ Time Frame: 16 weeks ]
    Pain threshold will be measured at basline and 16 weeks and correlated to inflammatory markers and anisotropy

Estimated Enrollment: 40
Study Start Date: November 2011
Estimated Study Completion Date: November 2013
Estimated Primary Completion Date: September 2013 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Desvenlafaxine
    Desvenlafaxine 50mg from week 1-8. At week 8 optional increase to 100mg if remission has not been attained.
    Other Name: Pristiq
Detailed Description:
40 subjects will be included in the study. Diagnosis will be confirmed by MINI. Participants will be characterised using questionnaires, pain threshold, cognition, facial expression recording and MRI. Desvenlafaxine will be initiated at 50mg AM. At week 8 Desvenlafaxine may be increased to 100mg as clinically indicated. Measures will be repeated at the end of the study.
