Understanding the Mechanism of Ketamine in Ketamine-Assisted Psychotherapy

Written By Naveen Thomas

Ketamine has garnered attention not only as an anesthetic but also for its intriguing effects on mood and cognition. Its role as an NMDA (N-methyl-D-aspartate) receptor antagonist is at the heart of its action. By blocking these receptors, ketamine disrupts the brain's normal excitatory signaling, leading to a cascade of neurobiological changes.

Some of the benefits of ketamine include:

  1. Increased Release of Glutamate: One key effect of NMDA receptor antagonism is an increased release of glutamate, the primary excitatory neurotransmitter in the brain. This rise in glutamate activity triggers several downstream effects, particularly in areas of the brain associated with learning, memory, and emotional regulation.

  2. Antidepressant Effects: By acting on the brain's NMDA receptors, ketamine can produce rapid antidepressant effects, especially in individuals with treatment-resistant depression. Additionally, it may induce dissociative effects, leading to a sense of detachment from one's body and surroundings, which some individuals may find therapeutic in certain contexts.

  3. Synaptic Plasticity: Ketamine also promotes synaptic plasticity, the brain's ability to adapt and reorganize itself by forming new synapses. This plasticity is crucial for enhancing creativity and flexible thinking. By facilitating these processes, ketamine may help individuals break free from rigid thought patterns, allowing for a more dynamic approach to problem-solving and creativity.

Understanding these mechanisms provides valuable insights into how ketamine can be harnessed not just therapeutically for mood disorders but also potentially as a catalyst for cognitive enhancement.

I have been a practicing psychiatrist for nearly 20 years. I graduated from Emory University in Atlanta, Georgia and completed my medical school training at Emory University School of Medicine. I then went on to complete my post graduate psychiatric residency training at the University of North Carolina in Chapel Hill, North Carolina.

I became interested in the field of holistic/integrative psychiatry after experiencing the ongoing frustrations of the primarily medication-centered approach that I was trained in. Many of my patients were experiencing consistently disappointing results in achieving a state of greater healing and peace, despite significant efforts from all concerned. I began to suspect that the conventional allopathic model of medical and psychiatric care that focuses primarily in symptom reduction had very significant limitations.

I was gradually drawn to the field of integrative psychiatry, which emphasizes a more comprehensive approach that takes into account the profound interconnectedness between mind, body, and spirit and looks to address the root causes of challenging mental health symptoms.

My journey into this field formally began with a Fellowship Program through the University of Arizona Center for Integrative Medicine founded by Dr. Andrew Weill. This program taught me to begin to focusing on optimal nutrition diet, gut health, exercise, and mind/body exercises, to name a just a few.

As I began to start practicing the integrative tools that I learned and helping my patients address the root causes of their symptoms, I was delighted to see that more of my patients were making more meaningful gains in their own healing.

I eventually became certified through the Ketamine Training Center in another very powerful tool called Ketamine Assisted Psychotherapy. I have been consistently amazed at the transformations in the lives of my patients that committed to this process.

I look forward to being your partner on your journey to optimal health.
