Connectivity Changes Associated With Ketamine Assisted Psychotherapy for PTSD

A total of 14 adult patients with PTSD will be recruited from UNM outpatient clinics and undergo rsfMRI and behavioral assessment prior to ketamine treatment. They will complete baseline scan at day one, a preparatory session (initial part of KAP), IM ketamine treatment, then within 24 hours, an integration session to take advantage of neuroplasticity for optimal therapeutic progress. Each participant will have two complete KAP sessions (preparation, treatment, and integration) followed by rsfMRI within approximately 24 hours, and again approximately two weeks after the completion of the second KAP session. Patients will also have repeat clinical assessments after each treatment. Changes in PTSD symptoms will be correlated with changes in connectivity at each rsfMRI.
