Post-traumatic stress disorder

Post-traumatic stress disorder (PTSD) is a mental health condition that can develop after experiencing or witnessing traumatic events such as accidents, violence, or life-threatening situations. It affects how the brain processes fear, memory, and stress, often keeping the body in a heightened state of alert even when the danger has passed.

This can lead to symptoms such as flashbacks, nightmares, anxiety, emotional numbness, irritability, and difficulty sleeping. PTSD is also associated with changes in brain regions like the amygdala, hippocampus, and prefrontal cortex, which are involved in fear response, memory processing, and emotional regulation. These changes can make it difficult to distinguish past trauma from present safety, and in some cases, symptoms may persist despite therapy or medication.

Gino Ang, MD, and the team at the Ketamine Center of Connecticut specialize in ketamine infusions that safely and efficiently address the symptoms associated with PTSD, including treatment-resistant cases. To learn if you’re a good candidate for ketamine treatment, schedule an appointment at our Milford or Westport office today.

As symptoms lift, many patients describe…

Flashbacks losing their intensity, nightmares reducing, hypervigilance calming, emotional numbing easing, triggers softening — and hope beginning to return. Improvement is measured with clinically validated rating scales, so progress is tracked rather than assumed.

How ketamine may help

By working through the glutamate system and supporting neural repair, ketamine may help calm the brain’s overactive threat response — softening triggers so rest, and the work of healing, become possible again. Treatment is delivered as a precise sub-anesthetic dose by a board-certified anesthesiologist, with hospital-grade Caretaker® monitoring throughout.

What treatment looks like

The standard protocol is a series of 6 infusions over about 12 days, each in a private room with dim lighting, music, and a clinician beside you the whole time. Most infusions take about 40–60 minutes, and many patients move to occasional as-needed booster infusions afterward to maintain results. We never recommend stopping your prescribed medication — ketamine is used alongside your existing care.

What many patients experience as symptoms begin to lift

By influencing brain circuits involved in memory processing and emotional response, ketamine may help reduce the intensity and emotional impact of traumatic memories. While these memories do not disappear, they often become less vivid and less overwhelming, allowing individuals to recall past events with greater emotional distance. This can support improved coping, reduce reactivity to triggers, and help patients regain a sense of control over their thoughts and experiences.

By modulating neural pathways involved in fear processing and sleep regulation, ketamine may help decrease the frequency and intensity of trauma-related nightmares. Many patients report more restful and uninterrupted sleep, which supports emotional recovery, improves daytime functioning, and helps restore overall well-being.

By influencing brain systems involved in threat detection and stress response, ketamine may help reduce the heightened state of alertness commonly seen in PTSD. As the “fight or flight” response begins to settle, many patients experience a greater sense of safety, allowing both the mind and body to relax. This can lead to improved focus, reduced anxiety, and a more stable emotional state in daily life.

By supporting neural pathways involved in emotional regulation and reward processing, ketamine may help restore a more balanced emotional response. Instead of feeling detached or disconnected, many patients begin to reconnect with their emotions and relationships, allowing for greater engagement in daily life and improved interpersonal connections.

By modulating neural circuits involved in fear conditioning and threat response, ketamine may help reduce sensitivity to triggers associated with past trauma. Everyday sights, sounds, or situations that once provoked intense reactions may become more manageable, allowing patients to respond with greater emotional control and reduced anxiety in daily life.

By supporting neural pathways involved in mood regulation and cognitive flexibility, ketamine may help alleviate persistent symptoms and improve overall emotional outlook. As symptom burden decreases, many patients report a renewed sense of control, greater resilience, and a more hopeful perspective on their future and recovery.

Frequently Asked Questions

 

PTSD develops after you experience a dangerous, traumatic, or scary event. You may be personally involved in the incident or hear about it from a family member or friend who experienced the event. PTSD often occurs following events such as:
 
  • Military duty
  • Gun violence
  • Physical assault
  • Sexual assault
  • Severe accident
  • Natural or man-made disasters
  • PTSD may also arise after the sudden death of a loved one or you experience a crime, such as a home invasion or theft.

 

PTSD symptoms usually appear within a few months of the traumatic event, but they may be delayed for years. The symptoms of PTSD last at least a month. During that time you may:
  • Have flashbacks or dreams about the event
  • Experience hypersensitive emotions
  • Feel angry, irritable, or edgy
  • Develop depression
  • Be easily startled
  • Blame yourself for the event
  • Avoid people and places that remind you of the event
Many patients find they have a hard time remembering specific details about the event. Flashbacks and dreams often trigger anxiety and physical symptoms such as shortness of breath.

 

The current psychiatric treatments for PTSD, antidepressants and psychotherapy, fail to improve symptoms in many patients. While ketamine is an experimental treatment for PTSD, doctors in Veterans Affairs medical centers have reported successful results using it to treat vets who haven’t obtained relief with the standard therapies.
At high doses, ketamine is a safe anesthetic. When given at low doses, however, ketamine improves the symptoms caused by a variety of mental health disorders, including PTSD, depression, and anxiety.
Ketamine balances the levels of glutamate, a brain chemical directly involved in psychological symptoms. The medication also restores connectivity between neurons. By directly targeting the brain, ketamine can work rapidly, often improving symptoms within hours.

 

During your treatment, you’ll relax in a private room while an anesthesiologist at Ketamine Center of Connecticut gives you ketamine through an intravenous (IV) infusion. They use a pump to ensure you receive the best dose and monitor your heart rate and blood pressure. Your treatment takes about 90 minutes, including your recovery time.
If you respond to your ketamine treatment during the first two infusions, your provider at Ketamine Center of Connecticut recommends a series of six total treatments. A series of infusions produce longer-lasting results.
