Dr Yost, in a career renaissance after 25 years as a psychiatrist, has retrained through multiple CME courses over the past five years at https://psychiatryletter.com/ in what can be called classical psychiatry, prioritizing basic clinical research as best exemplified in the 2007, two volume 1100 page tome, Manic-Depressive Illness – Bipolar Disorders and Recurrent Depression by Goodwin and Jamison and more recently in the 2019 Clinical Psychopharmacology – Principals and Practice by Nassir Ghaemi MD.
This retraining includes the concepts of a Diagnostic Hierarchy and Diagnostic Validators used in other medical specialties and published for psychiatry over 40 years ago but not adopted by the DSM. Experts in other fields of medicine know that a valid diagnosis can not be based on symptoms alone as promoted in the DSM.
Also included in classical psychiatry is the recently rediscovered clinical presentation Mixed Depression, described since the late 19th century, comprising 60% of all depressive illness while pure depression and mania comprise only 20% each. Clinical studies indicate that antidepressants can aggravate mixed depression and increase suicidality.
Dr Yost follows international soccer, a plant-based diet and is a competitive masters swimmer.
