Physiological and Cognitive Biomarkers for Ketamine’s Antidepressant Effects

Anxious depression is a particularly difficult-to-treat subtype of depression. Patients with anxious depression do not respond as well to currently available antidepressant medications. Nevertheless, in previous studies, low dose IV ketamine, which rapidly decreases symptoms of depression within hours in many patients with “treatment-resistant” depression, has been associated with superior efficacy in those individuals with anxious compared with non-anxious depression.

In order to understand this unique effect more fully, the current protocol is aimed at further delineating biomarkers of ketamine’s effects among individuals with treatment-resistant anxious depression compared to those with nonanxious depression.

Measures Used

Hamilton Depression Rating Scale
The Hamilton Depression Rating Scale (HDRS) is a multiple item questionnaire used to provide an indication of depression, and as a guide to evaluating recovery. The scale consists of 17 items which each item being scoring on a 3 or 5 point scale. The higher the score, the more likely a person is depressed.

Data attribution

A large set of the trials in our database are sourced from ClinicalTrials.gov (CTG). We have modified these post to display the information in a more clear format or to correct spelling mistakes. Our database in actively updated and may show a different status (e.g. completed) if we have knowledge of this update (e.g. a published paper on the study) which isn't reflected yet on CTG. If a trial is not sourced from CTG, this is indicated on this page and you can follow the link to the alternative source of information.
