As we know, no genetic test is ever perfect or absolute. Watch this short video as Dr. David Rosenthal discusses genetic testing in his video Clinical Applications of Advanced Genetics.

FULL TRANSCRIPT

As we know, no genetic test is ever perfect or absolute.

It’s one of the problems with this genetic testing is that we wish they could predict 100% of the time what you’re going to do when you make that decision to try medication. The genetic testing is particularly useful for people who’ve been treatment resistant. But a lot of people do the testing at the beginning and don’t wait until the patient is resistant before trying it. But you know, so often people want the test to be perfect and absolute. And obviously, no genetic test ever is going to be that way.

Gene X Environment Interaction

  • Depression scores (BDI) increase with increased childhood trauma
  • MTHFR genetic risks amplifies these effects

This slide was a slide that I gave in the last lecture. It’s a great one to illustrate the point of gene environment interaction when it comes to the MTHFR gene. So, as we know, the MTHFR genes are more than one MTHFR gene. You can see that the black line there represents a childhood trauma and depression score. So obviously, if you’ve been exposed to enough childhood trauma, your risk of becoming depressed at some point in your life is significantly increased over and above that of somebody who doesn’t have childhood trauma. But now, when you introduce MTHFR variants, and have difficulty methylating folic acid, you can dramatically increase the risk of becoming depressed as an adult.

SLC6A4 Genotypes
This just illustrates, this is a slide I showed in the last lecture about really just summarizing the different genotypes, the two short alleles being the poor responders. Another significant thing when you have two short alleles and elevated stress-induced cortisol, these people have the greatest cortisol fluctuations in response to stress when you see somebody with two short alleles. I often think about using phosphatidylserine or something to help regulate cortisol levels.

Ion channel genetic variants are common across many mental health conditions
These ion channel variants are common across several different mental and emotional conditions. So here are some of the traditional ways to tone down that system is using heavy duty mood stabilizers.

Second generation antipsychotics, Lamotrigine, when we have our bipolar two patients, Lithium. But Omega-3 fatty acids also tone down excessive glutamate activity, and so does N-acetylcysteine and magnesium. So magnesium, Omega-3’s and N-acetylcysteine are all good at lowering excessive glutamate activities, especially in somebody who’s not bipolar or not schizophrenic, where you really don’t want to go to any of those heavy-duty mood stabilizers.

Will Van Derveer, MD is co-founder of Integrative Psychiatry Institute (IPI), along with friend and colleague Keith Kurlander, MA. He co-created IPI as an expression of what he stands for. First, that anyone can heal, and second that we medical providers must embrace our own healing journeys in order to fully command our potency as healers.

Dr. Van Derveer spent the last 20 years innovating and testing a comprehensive approach to addressing psychiatric challenges which transcends the conventional model he learned in medical school at Vanderbilt University and residency at University of Colorado, while deeply engaging his own healing path.

He founded the Integrative Psychiatric Healing Center in in 2001 in Boulder, CO, where he currently practices. Dr. Van Derveer regards unresolved emotional trauma as the most significant root cause of psychiatric symptoms in integrative psychiatry practice, along with gut issues, hormone imbalances, inflammation, mitochondrial dysfunction, and other functional medicine challenges. He is trained in Somatic Experiencing, EMDR, Internal Family Systems, and other psychotherapy techniques. His current clinical passion is psychedelic-assisted psychotherapy, which he mentors interested doctors in providing. An avid meditator, he has been a meditation instructor since 2004.

For the past several years Dr. Van Derveer has taught psychiatrists and other psychiatric providers integrative psychiatry in a number of settings, including course directing the CU psychiatry residents’ course as well as with Scott Shannon and Janet Settle at the Psychiatry MasterClass. In addition to his clinical work and teaching, he was co-investigator in 2016 a Phase II randomized clinical trial, sponsored by the Multidisciplinary Association for Psychedelic Studies (MAPS). He continues to support this protocol, now in a Phase III clinical trial under break-through designation by FDA.

Dr. Van Derveer is a diplomate of the American Board of Integrative and Holistic Medicine (ABoIHM) since 2013, and he was board certified in the first wave of diplomates of the new American Board of Integrative Medicine (ABIM) in 2016.
