Glossitis that is often tender/painful, caused by complete atrophy of the lingual papillae (depapillation). The dorsal tongue surface may be affected totally, or in patches, and may be associated with a burning sensation, pain and/or erythema. Atrophic glossitis is a non-specific finding, and has a great many causes, usually related to iron-deficiency anemia, pernicious anemia, B vitamin complex deficiencies, unrecognized and untreated celiac disease (which often presents without gastrointestinal symptoms), or other factors such as xerostomia (dry mouth). Although the terms Möller and Hunter glossitis were originally used to refer to specifically the glossitis that occurs in vitamin B12 deficiency secondary
Neurogenic inflammation vasomotor rhinitis, fibromyalgia, eczema, rosacea, dystonia, and multiple chemical sensitivity. In migraine, stimulation of the trigeminal nerve causes neurogenic inflammation via release of neuropeptides including Substance P, nitric oxide, vasoactive intestinal polypeptide, 5-HT, Neurokinin A and CGRP. leading to a "sterile neurogenic inflammation." Magnesium deficiency causes neurogenic inflammation in a rat model. Researchers have theorized that since substance P which appears at day five of induced magnesium deficiency, is known to stimulate in turn the production of other inflammatory cytokines including IL-1, Interleukin 6 (IL-6), and TNF-alpha (TNFα), which begin a sharp rise at day 12, substance P is a
