Post-Traumatic Stress Disorder Traumatic Brain Injury | Procedure: subanesthetic ketamine infusions and bilateral cervical sympathetic blocks |
The primary objective of this study is to assess the impact of a combined protocol of subanesthetic ketamine infusions (SKI) and bilateral cervical sympathetic blocks (CSB) on aging, as measured by the GrimAge epigenetic clock.
The secondary objective of this study is to assess the impact of this treatment paradigm on PTSD and mental health, as measured over a 6 month time period using the following questionnaires: Post-traumatic Stress Disorder Checklist (PCL-5), Patient Health Questionnaire 9 (PHQ-9), Depressive Symptom Index-Suicidality Subscale (DSI-SS), Generalized Anxiety Disorder 7-item (GAD-7), and Neurobehavioral Symptom Inventory (NSI).
The tertiary objectives of the study are to investigate if PTSD is associated with significantly reduced free testosterone levels and increased C-reactive protein (CRP) levels.
