The Research Behind Ketamine-Assisted Therapy
My clients come to this work from a lot of different places. Some have tried everything else and are ready for something different. Some are deep in the research phase and want to understand the science before they commit.
What follows isn't an exhaustive literature review. It's a starting point. I've been doing ketamine-assisted psychotherapy since 2020, and these are the studies I return to most when I want to understand what's actually happening, underneath the hype.
If you're in California and this work sounds like what you've been looking for, a 20-minute consult is a good place to start.
Why Integration Matters in Ketamine Therapy
This is the part that gets left out of most conversations about ketamine. The medicine opens a window. What you do with that window determines whether anything actually changes.
Ketamine works by temporarily enhancing neuroplasticity: your brain's ability to form new connections. Research is now showing that this window is real, and that working with a therapist during and after it shapes your long-term outcomes. Without support, that window closes and old patterns return.

Ketamine for Depression
This is where most of the research started, particularly for people whose depression hasn't responded to medication or traditional therapy. The evidence here keeps growing.

Ketamine for Anxiety
For many of my clients, anxiety is the thing that actually runs their life, more than depression ever did. The research here is newer but promising, especially for people whose anxiety hasn't responded to conventional treatment.

Ketamine for PTSD and Trauma
Some of the most meaningful research for the clients I work with. Ketamine doesn't just lift mood. It may create a window where the nervous system can actually update old threat responses, the ones that haven't shifted no matter how much you've talked about them.

Ketamine and Neurodivergence (ADHD and Autism)
This is an area I follow closely because so many of the people I work with are neurodivergent. The research is early, but the theoretical basis is solid: ketamine works on the glutamate system, which plays a key role in cognitive flexibility, emotional regulation, and sensory processing, all areas that can be dysregulated in ADHD and autism.

The research on ADHD specifically is still emerging in peer-reviewed literature, but the mechanism is worth understanding: ketamine's effect on neuroplasticity may help create new pathways for focus, regulation, and processing that stimulants alone don't reach.
Personal Stories
Sometimes the research isn't what lands. Sometimes it's someone else's words.

If you've read this far, you're probably someone who needs to understand something before you can trust it. That's not a barrier to this work. It's often a sign you're ready for it.
I've been doing ketamine-assisted psychotherapy since 2020, with particular focus on nervous system sensitivity and neurodivergence. My work combines somatic therapy, art making, and psychedelic integration in collaboration with a licensed MD prescriber, which means your care is coordinated, not fragmented.
