Post-traumatic stress disorder affects about 6% of Americans at some point in life, with symptoms like intrusive memories, hypervigilance, and avoidance that persist long after trauma exposure. Current treatment centers on trauma-focused psychotherapy and antidepressants, which help many people but leave substantial room for improvement in response rates and speed of relief.
What's actually going on in research
Trials are testing MDMA-assisted therapy for treatment-resistant PTSD, psychedelics like psilocybin that may reset fear circuits, new medications targeting stress hormone systems, and brain stimulation methods. Researchers are also studying how to personalize treatment based on trauma type and symptoms, and testing briefer therapies that might reach more people.
MDMA-assisted therapy
Phase 3 trials showed that MDMA given during therapy sessions helped about two-thirds of participants with severe PTSD no longer meet diagnostic criteria. The FDA is reviewing the data for potential approval in 2024.
Psychedelic research
Psilocybin and other psychedelics are being tested to see if they can help extinguish traumatic memories and restore emotional flexibility. Early results suggest rapid symptom reduction in some participants.
Stress system targets
New drugs aim at the body's stress response systems, including cortisol regulation and receptors involved in fear learning. These approaches try to address PTSD's biological roots rather than just symptoms.
What to know before you search
Eligibility typically depends on PTSD severity, time since trauma, current symptoms, prior treatment response, and whether participants can avoid certain medications during the study.
What types of trials are currently open
- Psychotherapy trials — Testing variations of trauma-focused therapy, often comparing new approaches to established methods like prolonged exposure or cognitive processing therapy.
- Medication trials — Testing antidepressants, anti-anxiety medications, and drugs targeting stress hormones to see if they reduce PTSD symptoms more effectively than current options.
- Psychedelic-assisted therapy — Studies combining MDMA, psilocybin, or other compounds with therapy sessions, typically requiring overnight stays and extensive psychological support.
- Brain stimulation — Testing techniques like transcranial magnetic stimulation (TMS) or neurofeedback to change brain activity patterns associated with PTSD.
- Prevention studies — Following people shortly after trauma to test whether early intervention can prevent PTSD from developing.

Written Exposure Therapy for Childbirth-related Post-Traumatic Stress
In this research study, the investigators hope to determine whether Written Exposure Therapy is a feasible intervention for postpartum women experiencing trauma symptoms related to childbirth to complete. Written Exposure Therapy involves five structured psychotherapy sessions that can be conducted over telehealth.
Virtual Reality Assisted Trauma Focused CBT
Virtual Reality (VR) is becoming an increasingly important tool in mental healthcare, offering new ways to enhance patient treatment. Over the past decade, there's been growing interest in using VR therapies because they create immersive, controlled environments tailored to individual therapeutic needs. In a safe and controlled, therapeutic setting, these environments can help patients work through difficult emotions and experiences. However, despite its potential, the widespread adoption of VR in routine mental healthcare has been slow due to the high costs of the necessary technology, making it less accessible for many patients and therapists. VR is particularly valuable in mental health therapy because it can evoke strong cognitive, emotional, and physical responses, much like traditional therapeutic techniques that use imagery or visualisation. Research has shown that VR can offer unique benefits, such as real-time monitoring of a patient's responses and creating customised exposure therapies that safely mimic real-world scenarios. These features can be incredibly effective in treating conditions like Post Traumatic Stress Disorder (PTSD), anxiety, and phobias. This study aims to overcome the barriers to VR adoption by developing a more affordable approach to creating virtual environments that can be used in everyday mental healthcare. Collaborating with a software company called ProPeer Solutions, the project has created a process called "VR Photoscan." This method allows for the creation of virtual environments at a lower cost, making it more accessible to clinics and therapists. The ultimate goal is to integrate VR into standard mental health treatments, making this innovative technology available to more people who could benefit from it, specifically within routine psychological therapy services for adults with PTSD.
