Dr. Steven Levine was one of the very first US doctors to offer ketamine infusion therapy for depression. A psychiatrist in Princeton, NJ, he has been providing the treatment since 2011. Based on his experience treating over 400 patients, Dr. Levine has designed a study to see if successful antidepressant outcomes can be correlated with certain sensations that can occur during the infusion procedure.
In order for the study to remain independent and not rely on support from the pharmaceutical industry, Dr. Levine has launched a crowdfunding effort. See Does the Experience of Awe Predict Ketamine’s Rapid Antidepressant Effect? for a full description of the project and budget.
