The Limitations of Addisonian Criteria: Diagnosing B12 Deficiency

Introducing a video series on the many problems with conventional B12 testing.

Part 1 explores the traditional view of diagnosing B12 deficiency through the Addisonian criteria, focusing on hematological signs of pernicious anemia. However, this approach often leads to misdiagnosis or missed diagnosis of B12 deficiency, as the neurological and neuropsychiatric symptoms that often accompany B12 deficiency may not be present in conjunction with anemia.

This video examines the limitations of the Addisonian criteria and provides insight into how modern research increasingly recognizes the diverse symptoms associated with B12 deficiency. Additionally, this segment discusses the impact of folate food fortification and how it masks B12 deficiency, leading to a misdiagnosis or no diagnosis of a B12 deficiency. Join us for Part 1 of this informative series on B12 deficiency.
