Telogen Effluvium With Dysesthesia (TED) Has Lower B12 Levels and May Respond to B12 Supplementation

Abstract

We investigated a subtype of Telogen Effluvium associated with Dysesthesia, (TED) which was defined as the presence of Telogen Effluvium with severe itch, pain, soreness, burning, or formication in the absence of any inflammatory scalp disorder or medication associated with Telogen Effluvium or Dysesthesia. These are patients who present with a “burning” scalp or other dysesthesia associated with increased telogen hair shedding. Telogen Effluvium is not typically associated with any scalp symptoms.3 Other scalp dysesthesia studies have mentioned occasional patients in their study that were also diagnosed with Telogen Effluvium,1,2 but the clinical association of Scalp Dysesthesia and Telogen Effluvium has never been made as a distinct entity.
