Disentangling ADHD Tangles: Sentinels in Green Biomass.
Play • 56 min

Listen to Dr. Samuel Dismond explain an evolutionary perspective on what is commonly called ADD/ADHD. This evolution story recasts the so-called dysfunctions of ADHD as unique ultra-functions possessed by Sentinels. The story begins 100,000 years ago as our DNA became fixed as Homo sapiens. Within small primitive groups, the round scanning awareness of the Sentinel bloodline featured critically in the history of group survival.

Dr. D graphically illustrates how our very recent modern circumstance differs from our origin times. Our modern world has become a series of boxes connected by lines from kindergarten to career. These edges and squares can be challenging for the round awareness of Sentinels. Nonetheless, it is very possible for Sentinels to thrive and find themselves ‘in the right place, at the right time’ in their life.

The topics in this interview include:

  • Scientific parts and mysterious stories meet when our “quiet brains meet green biomass”.
  • What is a Sentinel?
  • Not a deficit but rather a valuable genetic variant: a new way to understand ADHD.
  • The powerful effect of green, natural environments on our brain.
  • Why modern life has become a series of lines and boxes.
  • How nature walks can untangle the tangles of life stories.

At the end of the episode Dr. D shares an evidence-based breath work technique  to help slow down and absorb while walking through green nature.

Dr. Samuel Dismond III, MD MBA, specializes in treating adults with ADHD. He provides a patient-centered approach and believes in the importance of the patient-doctor connection. Dr. D has been practicing as a  general physician for 32 years. He got his MD at the University Of Michigan Medical School as well as an MBA at the Stanford Graduate School of Business. Dr. D is a lifelong practitioner of qigong.
