Ketamine Assisted Psychotherapy

Ketamine: “the Anti-Medication” Medication

“With most medications, like valium, the anti-anxiety effect you get only lasts when it is in your system. When the valium goes away, you can get rebound anxiety. When you take ketamine, it triggers reactions in your cortex that enable brain connections to regrow. It’s the reaction to ketamine, not the presence of ketamine in the body that constitutes its effects”

~ John Krystal, MD, chief psychiatrist at Yale Medicine, pioneer ketamine researcher

 

History of Ketamine for Depression

 

In 2000, a Yale University group (Berman et al) reported the rapidly acting antidepressant effects of ketamine in patients with Major Depressive Disorder (MDD) in the first double‐blinded, placebo‐controlled trial of ketamine for MDD. Previously, Krystal et al (1994) established dosage guidance in their seminal study on the use of Ketamine for depression. Later studies have replicated the robust antidepressant effect of ketamine and showed that ketamine significantly reduces suicidal ideation in patients with depression.

Murrough et al (2013) gave six ketamine infusions over a 12‐day period in treatment‐resistant MDD patients, and 70.8% of these patients were responders to ketamine. In 2016 Singh et al demonstrated that twice‐ and thrice‐a‐week infusions of ketamine maintained the antidepressant efficacy in treatment‐resistant MDD patients. Mandal (2019) showed significant improvement in depression, anxiety and severity of illness starting within one hour of the first of 6 ketamine administrations and lasting until the 1-month follow-up.

 

How Does Ketamine Work?

Studies from Yale research labs showed that the drug ketamine, which was widely used as anesthesia during surgeries, triggers glutamate production, which, in a complex, cascading series of events, prompts the brain to form new neural connections. This makes the brain more adaptable and able to create new pathways, and gives patients the opportunity to develop more positive thoughts and behaviors. This was an effect that had not been seen before, even with traditional antidepressants.

Experts say ketamine needs to be part of a comprehensive treatment plan for depression

“Patients will call me up and say they don’t want any other medication or psychotherapy, they just want ketamine, and I have to explain to them that it is very unlikely that a single dose, or even several doses of ketamine alone, will cure their depression … it (ketamine) may provide rapid benefits that can be sustained with comprehensive treatment plans … it (ketamine) appears to help facilitate the creation new neural pathways that can help them develop resiliency and protect against the return of the depression.” 

~ Gerard Sanacora, MD, PhD, Yale Psychiatrist involved in many ketamine studies

At the Catalyst Center we offer Ketamine Assisted Psychotherapy, a comprehensive ketamine treatment program designed to maximize the efficacy of this cutting edge treatment

 

Ketamine Assisted Psychotherapy (KAP) combines the biochemical benefits of ketamine with evidence-based psychotherapy allowing you to maximize the positive impact of ketamine in your life. Initial research supports the promise of this approach to treatment.

Our findings suggest that KAP is an effective method for decreasing depression and anxiety in a private practice setting

~ Dore et al 2019
