Montreal Model of Care and Artistic Environments Enhance Ketamine Therapy for Depression

MONTREAL — The University of Montreal Hospital Center (CHUM) has recently unveiled two specially designed rooms aimed at optimizing the therapeutic environment for patients undergoing treatment for severe depression. This initiative builds upon the success of the “Montreal model,” a treatment approach demonstrating the effectiveness of integrating environmental factors into ketamine therapy.

The Role of Environment in Ketamine Treatment

The rooms are decorated with murals created by Montreal-based artist Mélissa Del Pinto, known for her large-scale paintings of birds. This artistic integration is a key component of the work led by Dr. Nicolas Garel and his team, who are studying the leverage of ketamine in treating depression. Dr. Garel emphasizes the importance of “extra-pharmacological factors” – elements outside of the medication itself – in both therapeutic response and patient safety.

“From creating environments that are welcoming, that are stimulating, the treatment already begins,” Dr. Garel stated. “Emphasizing that these environments are therapeutic, welcoming and demedicalized can really influence the treatment in a quite profound way.”

Ketamine and the Montreal Model

Ketamine, an anesthetic, has been utilized in depression treatment for decades and is considered a significant advancement in psychopharmacology. However, its effects are often short-lived, typically fading within seven to ten days. Research has shown that when administered within the framework of the Montreal model, ketamine can provide substantial benefits even at minimal doses.

Researchers believe ketamine, in conjunction with psychotherapy, allows patients to experience their emotions more intensely. Integrating ketamine into a therapeutic environment, combined with weekly psychotherapy, has shown to sustain symptom improvement for up to eight weeks after treatment completion.

Patient Experience and Preparation

The CHUM team’s focus on the patient experience stems from earlier observations. Dr. Paul Lspérance, director of the psychiatric neuromodulation unit, noted that patient feedback consistently highlighted the impact of environmental factors – such as lighting or temperature – on their perception of treatment effectiveness.

This emphasis on environment is particularly crucial with ketamine, as the substance can induce a state of vulnerability and heightened emotional sensitivity. Del Pinto’s murals were intended to create “windows” and “perspectives,” encouraging patients to recognize potential filters on their reality.

The Montreal model also prioritizes patient “priming” – preparing patients before treatment by encouraging them to reduce phone use and practice mindfulness exercises. This preparation, beginning at home, aims to foster a sense of commitment and active participation in their recovery.

Shifting the Paradigm of Treatment

Dr. Lspérance highlights a shift away from a purely medical model, where patients passively receive treatment, towards a model of patient empowerment. “We provide you with the springboard, but it’s you who does the triple jumps,” he explained. The goal is to enable patients to achieve lasting well-being, potentially reducing or eliminating the need for ongoing medication.

Dr. Garel echoes this sentiment, stating, “I often tell my patients that they are the treatment. You are not dependent on a substance that you passively receive at the hospital. You are the treatment, you are active. We are going to catalyze this process that you initiated.”

Addressing Discouragement and Fostering Neuroplasticity

Recognizing that patients seeking treatment at CHUM often feel discouraged after previous unsuccessful attempts, the team emphasizes the need for a new approach. They aim to challenge patients to consider alternative strategies and leverage ketamine’s potential to enhance neuroplasticity – the brain’s ability to form new connections and learn.

“Our approach is one anchored in values, of creating meaning,” Dr. Garel concluded. “There is a whole humanist, integrative, holistic component, which can be very destabilizing (…) especially for someone who tells us that if he comes here, it is because he is not capable of doing what we ask him to do. We tell him that we are there to support him.”
