What Causes PTSD?

What Causes PTSD?

Post-traumatic stress disorder (PTSD) is a serious mental health condition that can develop after a person experiences or witnesses a traumatic event. It is a complex condition that can be caused by a range of factors, and it can have a significant impact on an individual’s quality of life. In this blog, we will take a closer look at what causes PTSD and how ketamine therapy can help.


Trauma is the most significant risk factor for PTSD, it can take various forms, including physical, sexual, or emotional abuse, military combat, natural disasters, and accidents. The severity of the trauma and an individual’s proximity to the event play a crucial role in the development of PTSD. Trauma has a long-lasting impact on an individual’s life and can affect their daily functioning, making it difficult for them to cope with the aftermath of the traumatic event.


There is also evidence to suggest that genetics may play a role in the development of PTSD. Studies have shown that PTSD tends to run in families, suggesting that there may be a genetic component to the condition. However, more research is needed to understand the specific genes involved and how they contribute to PTSD.

Biological Factors

Abnormalities in neurotransmitters, the chemicals that transmit signals in the brain, have also been linked to PTSD. For example, studies have shown that individuals with PTSD tend to have lower levels of serotonin and norepinephrine, which are chemicals that play a role in pain perception and mood regulation. Additionally, some studies have suggested that individuals with PTSD may have an increased sensitivity to stress hormones, which can contribute to the development of PTSD symptoms.

Treatment with Ketamine

Ketamine therapy is an effective treatment option for PTSD. Studies have shown that ketamine can rapidly reduce symptoms of PTSD, often within hours of the first infusion. Ketamine works by blocking NMDA receptors in the brain, which can reduce pain and increase the levels of neurotransmitters such as glutamate and GABA, which can help to regulate the pain perception. Additionally, ketamine also promotes neuroplasticity in the brain, creating new neural pathways, allowing the individual to process traumatic memories differently. This can help individuals to better cope with difficult memories and emotions that may be associated with PTSD.

Ketamine therapy is usually administered in a clinical setting, and the treatment protocol is typically a series of infusions over a period of several weeks. The number of infusions required may vary depending on the individual’s needs and response to treatment. After the initial course of infusions, some patients may require maintenance infusions to maintain the positive effects of the therapy.

Final Thoughts

PTSD is a complex condition that can be caused by a range of factors, including trauma, genetics, and biological factors. While no single treatment works for everyone, ketamine therapy has shown promise in rapidly reducing symptoms of PTSD. If you are struggling with PTSD, it is important to seek help and support as soon as possible to prevent the development of more severe symptoms.
