Guest: Dr. Boris Heifets, Board-Certified Anesthesiologist and Neuroscientist
Introduction to the Episode
In this enlightening episode of the Science of Perception Box, hosts Dr. Heather Berlin and Dr. Christoph Koch engage in a deep conversation with Dr. Boris Heifets. The discussion centers around the interplay between psychedelics, the placebo effect, and their collective impact on mental health therapies. Dr. Heifets brings his extensive experience in anesthesiology and neuroscience to explore groundbreaking research that challenges traditional views on psychedelic-assisted treatments.
Dr. Heifets' Journey into Psychedelics and Anesthesiology
Dr. Boris Heifets delves into his personal and professional journey, explaining how his early fascination with psychedelics led him to anesthesiology—a field that allows close observation of consciousness and brain function through drug administration. Reflecting on societal skepticism, he shares:
“I think when I started medical school, my mom told me, drop it. You can’t have a career studying psychedelics. It’s hippie science.”
— Dr. Boris Heifets [03:12]
Choosing anesthesiology over psychiatry or neurology, Dr. Heifets found a specialty that aligned with his passion for applied neuroscience and the exploration of consciousness through pharmacological means.
Understanding Psychedelics and Their Therapeutic Potential
The conversation transitions to the nature of psychedelics and their therapeutic applications. Dr. Heifets categorizes psychedelics into classic types like LSD and psilocybin, and "psychedelic-adjacent" drugs such as MDMA. He emphasizes their ability to induce rapid and lasting perspective shifts without the need for daily intake:
“The effects are rapid. That perspective shift... and finally, the effects are durable. This is a sea change in how therapy is delivered.”
— Dr. Boris Heifets [10:00]
Dr. Heifets highlights the transformative potential of psychedelics in treating conditions like PTSD and depression, underscoring their profound impact on patients' mental states.
The Placebo Effect: A Dominant Force in Psychedelic Research
A significant portion of the discussion focuses on the placebo effect within psychedelic research. Dr. Heifets explains the complexities involved in isolating the drug's effects from the psychological and environmental factors that contribute to therapeutic outcomes:
“The debate is whether it's the drug or the therapeutic relationship that's responsible for these benefits.”
— Dr. Christoph Koch [11:02]
He articulates the ongoing debate in the scientific community about the extent to which the placebo effect versus the pharmacological action of psychedelics drives the observed therapeutic benefits.
Innovative Study: Ketamine During Anesthesia
Dr. Heifets introduces his pioneering study, where ketamine—a drug known for its psychedelic-like properties—is administered during general anesthesia to investigate its antidepressant effects without the patient's conscious experience of the drug. This approach aims to disentangle the drug's biochemical impact from the psychological context typically present in psychedelic therapies.
“What if we give a psychedelic class drug like ketamine during anesthesia?”
— Dr. Boris Heifets [18:00]
By integrating ketamine into the anesthetic regimen, Dr. Heifets seeks to understand whether the therapeutic benefits persist even when the drug's psychoactive effects are absent from the patient's conscious awareness.
Surprising Findings: The Power of Placebo
The study yielded unexpected results, revealing that both the ketamine and placebo groups experienced significant improvements in depression scores. This unexpected parity suggests a profound placebo effect influenced by the study's structure and the patients' psychological states.
“Both groups on average showed the same degree of improvement.”
— Dr. Christoph Koch [23:10]
Dr. Heifets reflects on the immense placebo effect observed, attributing it to the intensive patient engagement and the structured environment of the study which may have fostered hope and positive expectations.
Case Studies: Transformative Patient Experiences
Highlighting individual patient experiences, Dr. Heifets shares stories illustrating the therapeutic impact of the study's methodology. One notable case involved a woman who had suffered a traumatic attack and was experiencing acute stress disorder. During anesthesia, she underwent a vivid dream experience that allowed her to process and overcome her trauma.
“She dreamt she re-experienced the birth of her son... she has not had nightmares since.”
— Dr. Boris Heifets [40:55]
These narratives underscore the potential for non-pharmacological factors—such as guided experiences during anesthesia—to facilitate significant mental health improvements.
Exploring Alternatives: Dreams Without Psychedelics
Building on the study's findings, Dr. Heifets and his collaborator, Dr. Harrison Chow, explore methods to induce transformative dream states without the use of psychedelics. By carefully monitoring and adjusting anesthetic levels, they aim to recreate supportive psychological experiences that can lead to therapeutic outcomes similar to those achieved with psychedelic drugs.
“Wouldn't it be an interesting test if we could induce a psychedelic-like state without a psychedelic and get some of the same physiology and therapeutic effects?”
— Dr. Boris Heifets [33:32]
This innovative approach seeks to harness the psychological aspects of therapy, potentially offering alternative or complementary treatments for mental health disorders.
Implications for Future Therapy and Research
The episode concludes with reflections on the broader implications of Dr. Heifets' research. The findings challenge the necessity of psychedelic drugs for therapeutic benefits, suggesting that the psychological experience itself plays a crucial role. This insight opens new avenues for developing therapies that prioritize the patient's psychological state and environment.
“We need something. These patients went through something... And I think that's what defines this broad class [of drugs].”
— Dr. Boris Heifets [10:00]
Dr. Heifets advocates for a more nuanced understanding of therapeutic interventions, emphasizing the synergy between pharmacological and psychological factors in achieving mental health improvements.
Audience Takeaways
Listeners are encouraged to reconsider the role of psychological experiences in therapeutic settings and recognize the potential of non-pharmacological methods to foster mental well-being. The episode underscores the intricate relationship between mind and body, and how altering one's perception—whether through drugs or guided experiences—can lead to profound personal transformations.
Closing Reflections
Dr. Berlin and Dr. Koch wrap up the episode by inviting listeners to explore their own perception boxes and engage with the questions posed throughout the discussion. The hosts emphasize the importance of gratitude and self-awareness in personal growth, grounding the episode's scientific insights in everyday experiences.
“What aspect of yourself are you now grateful for that in the past, you struggled with or hated?”
