Clinical Trial Summary

The purpose of this study is to understand how ketamine brings about dissociative symptoms.

Description:

The goal of this proposed research is to record the effects of ketamine on brain activity to understand the changes that occur during antidepressant therapy and the side effect of dissociation. This research is designed to probe altered cognitive states associated with dissociation, depression, and other neuropsychiatric conditions.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of participants with dissociative events during ketamine infusion as assessed by CADSS (Clinician-Administered Dissociative State Scale)	The CADSS is an instrument for the measurement of dissociative symptoms. The CADSS comprises 23 subjective items and participant's responses are coded on a 5-point scale (0 = Not at all; 4 = Extreme). The higher the number on the CADSS, the more severe the symptoms.	up to 1 week
