Clinical Research on Ketamine-Assisted Therapy
This page highlights key research on how ketamine and Ketamine-Assisted Therapy supports depression, trauma, and emotional distress.
How Ketamine Works
Ketamine works differently from traditional antidepressants by acting on the brain’s glutamate system, which plays a central role in learning, memory, and emotional processing. Rather than gradually increasing neurotransmitters over time, ketamine triggers a rapid increase in glutamate release, initiating a cascade of changes in the brain.
This process activates pathways involved in synaptic plasticity, including increased release of brain-derived neurotrophic factor (BDNF) and activation of mTOR signaling—both of which are associated with the growth and strengthening of neural connections [1][2]. These changes can help restore disrupted neural networks involved in mood, stress, and trauma.
Research suggests that ketamine may temporarily increase the brain’s capacity for new learning and emotional processing, making it easier to shift entrenched patterns and form new associations [3]. This window of enhanced neuroplasticity is one reason ketamine is used in conjunction with psychotherapy, allowing new insights and responses to be more readily integrated.
Over time, repeated sessions may support more lasting changes in how the brain processes emotion, stress, and relational experiences.

Clinical Research
Ketamine-assisted psychotherapy (KAP) is an emerging treatment approach that combines ketamine with psychotherapy to support treatment of depression, trauma, and related conditions.
Research has consistently shown that ketamine produces rapid reductions in depressive symptoms, PTSD symptoms, and suicidal ideation [1][2]. In addition to these effects, there is a growing body of research exploring how ketamine is used in combination with psychotherapy to enhance and sustain therapeutic outcomes.
Clinical studies and reviews suggest that ketamine may be particularly effective when paired with psychotherapy, supporting processes such as emotional processing, fear extinction, and memory reconsolidation [3][4]. These mechanisms are central to trauma and mood disorder treatment and may allow for more effective engagement with therapeutic interventions.
Emerging research on ketamine-assisted psychotherapy indicates improvements in depression, anxiety, and trauma-related symptoms, particularly when treatment includes multiple sessions and structured therapeutic support [5].
Ketamine-assisted psychotherapy is an evolving, research-informed treatment model that integrates biological and psychological approaches to support meaningful and lasting change.
