Understanding Ketamine's Dissociative Effects (KD Study)
July 18, 2023 updated by: Karl Deisseroth, Stanford University
Understanding Ketamine's Dissociative Effects in Epilepsy (KD Study)
The purpose of this study is to understand how ketamine brings about dissociative symptoms.
Study Overview
Detailed Description
The goal of this proposed research is to record the effects of ketamine on brain activity to understand the changes that occur during dissociation in epilepsy patients with stereoEEG.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of participants with dissociative events during ketamine infusion as assessed by CADSS (Clinician-Administered Dissociative State Scale)
Time Frame: up to 1 week
|
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.
