Effect of Antidepressants on White Matter Structure
Recruitment status was Recruiting
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.

|Official Title:||White Matter Structure and Response to Treatment With Antidepressants: a Study of Desvenlafaxine in Major Depression. A Pilot Study|
- Anisotropy [ Time Frame: 16 weeks ] [ Designated as safety issue: No ]Degree of anisotropy will be measured at baseline and 16 weeks and correlated to remission status
- cognitive measures [ Time Frame: 16 weeks ] [ Designated as safety issue: No ]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 ] [ Designated as safety issue: No ]Pain threshold will be measured at basline and 16 weeks and correlated to inflammatory markers and anisotropy

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.
