Clinical Trial Summary

Ketamine has been shown to decrease symptoms of anxious depression quickly. This decrease has been shown to last for up to one month. MRI technology will be used before and after ketamine for patients with depression to examine the extent to which certain brain areas predict ketamine's antidepressant effects.


Description:

Ketamine's antidepressant effects were measured with Hamilton Depression Rating Scale (HDRS). MRI data will also be analyzed to examine the extent to which certain brain areas predict ketamine's antidepressant effects.

Outcome

Type Measure Description Time frame Safety issue
Primary Change in Hamilton Depression Rating Scale (HDRS) From Baseline/Minute 0 to 4 Hours Post-infusion. Hamilton Depression Rating Scale; possible scores range from 0 to 81 with higher scores indicating higher depression symptoms
Change will be calculated by difference between HDRS from Minute 0 to Minute 240.
4 hours
Secondary Percent Change in Tissue Fractional Anisotropy Quantification (Left Inferior Longitudinal Fasciculus) Free-water imaging, a two-compartment diffusion model, was employed to quantify tissue fractional anisotropy (FAt) pre- and post-infusion 4 hours
Secondary Percent Change in Tissue Fractional Anisotropy Quantification (Right Inferior Longitudinal Fasciculus) Free-water imaging, a two-compartment diffusion model, was employed to quantify tissue fractional anisotropy (FAt) pre- and post-infusion 4 hours
Secondary Percent Change in Tissue Fractional Anisotropy Quantification (Left Superior Longitudinal Fasciculus) Free-water imaging, a two-compartment diffusion model, was employed to quantify tissue fractional anisotropy (FAt) pre- and post-infusion 4 hours
Secondary Percent Change in Tissue Fractional Anisotropy Quantification (Right Uncinate Fasciculus) Free-water imaging, a two-compartment diffusion model, was employed to quantify tissue fractional anisotropy (FAt) pre- and post-infusion 4 hours
