About this trial
Develop a NIRSIT testing protocol that can be administered in the diagnostic setting and reliably distinguishes the symptoms and severity of depression, with the help of repeated measure (up to five visits per subject) comparison of patients being treated for Major Depressive Disorder with control, non-depressed subjects.

Treatment groups
Trial outcomes
Primary outcomes
Change in Frontal Oxyhemoglobin concentration before initiation of treatment for MDD
Change in Oxyhemoglobin concentration in frontal blood from the baseline during the performance of Verbal Fluency Task (VFT) and Cartoon humor reaction task (CHR) by the subject.
Change in Frontal Oxyhemoglobin concentration 3 weeks after initiation of treatment for MDD
Change in Oxyhemoglobin concentration in frontal blood from the baseline during the performance of Verbal Fluency Task (VFT) and Cartoon humor reaction task (CHR) by the subject.
Change in Frontal Oxyhemoglobin concentration 6 weeks after initiation of treatment for MDD
Change in Oxyhemoglobin concentration in frontal blood from the baseline during the performance of Verbal Fluency Task (VFT) and Cartoon humor reaction task (CHR) by the subject.
Change in Frontal Deoxyhemoglobin concentration before initiation of treatment for MDD
Change in Deoxyhemoglobin concentration in frontal blood from the baseline during the performance of Verbal Fluency Task and Cartoon humor reaction task by the subject.
Secondary outcomes
Hamilton Depression Rating Scale (HAM-D) Score
Changes in HAM-D Scores before, during and after treatment of MDD. The score range is 0-50, with 50 indicating most severe depression.
Beck's Depression Inventory - II (BDI-II) Scores
Changes in BDI-II Scores before, during and after treatment of MDD. The score range is 0-63, with 63 indicating most severe depression.
Patient Health Questionnaire-9 (PHQ-9) Scores
Changes in PHQ-9 Scores before, during and after treatment of MDD. The score range is 0-27, with 27 indicating most severe depression.
