“…The authors also reported some improvement in patients following B12 replacement, suggesting a relationship between B12 deficiency and auditory dysfunction. In another study, it was shown that increased rates of absent vestibular evoked myogenic potentials and decreased amplitudes with normal latencies in patients with vitamin B12 deficiency attributed to peripheral vestibular hypofunction 20 …”

“…In another study, it was shown that increased rates of absent vestibular evoked myogenic potentials and decreased amplitudes with normal latencies in patients with vitamin B12 deficiency attributed to peripheral vestibular hypofunction. 20 It was reported that B12 deficiency was associated with increased inflammation, and hearing loss is perhaps the result of inflammation. 21 As another mechanism, increased methylmalonic acid as a result of vitamin B12 deficiency can cause neurotoxicity and vasculotoxicity in the inner ear.…”

Aim The aim of this study is to investigate the effects of vitamin B12 deficiency on hearing in school‐aged children by pure‐tone audiometry. Methods Forty‐three vitamin B12‐deficient children and 37 age‐matched control subjects were enrolled in the study. Tympanometric evaluations and pure‐tone audiometry including high frequencies were performed on the subjects. The results were compared between the two groups. Results Both right and left ear pure‐tone hearing thresholds (PTHTs) at 0.25–4 kHz, and four‐frequency pure‐tone average values were significantly better in the control group compared with the patient group (P < 0.05). However, PTHTs at 8–16 kHz were not different between the two groups (P > 0.05). Vitamin B12 level also did not show any significant correlation with the PTHTs at 0.25–16 kHz (P > 0.05). Conclusion This study indicates that vitamin B12 deficiency may contribute to hearing impairment at low frequencies as a possible aetiological factor in children.

“…In other in vivo trials with mice fed an edible mushroom, Coriolus versicolor, revealed no change in the dentate gyrus volume or proliferation in newly generated neurons. It was found that mice treated with this mushroom biomass supplementation had a significant increase in the complexity of the long and short immature neurons (increase in dendritic complexity) (63).…”

Nutraceuticals comprise dietary supplements, functional foods, medicinal foods, and pharmaceuticals. However, to date all these concepts are interpreted in different ways with the rapid increasing knowledge on nutrition, medicine, and plant biotechnology changing the concepts about food, health and agriculture. What matters are the bioactive elements conveyed by foodstuffs as nutrients or non-nutrients, which interfere with human metabolism and have impact on health, aging and well-being. Food, not nutrients, is the fundamental unit in nutrition and edible mushrooms, are fungi that supply unique biological compounds, different from plant or animal origin, which significantly impact on health status. Their influence on medicinal interventions has been known and studied for many years. The role on neurodegenerative disorders has been recently investigated and their significance on many other diseases has been well demonstrated. On this note it is synthesized the more recent knowledge of some edible mushrooms and preparations on Ménière’s disease, a lifelong condition it can develop at any age, but most commonly appearing between 40 and 60 years of age.

Food, not nutrients, is the fundamental unit in nutrition, and edible mushrooms are fungi that supply unique biological bioactive compounds, different from plant or animal origin, which significantly impact human health status. However, to date all these concepts are interpreted in different ways, with rapidly increasing knowledge on nutrition, medicine, molecular biology, and plant biotechnology changing the concepts of food, health, and agriculture. The bioactive elements conveyed by foodstuffs as nutrients or non-nutrients interfere with human metabolism and have influence on health, aging, and well-being. The influence of edible mushrooms on medicinal interventions has been known and studied for many years and their latest role in neurodegenerative disorders has been recently investigated, while their significance on many other diseases has been well demonstrated. Despite considerable research, the etiology and pathogenesis of Ménière’s disease remains controversial and undefined, although usually associated with allergic, genetic, or trauma sources, and with viral infections and/or immune system-mediated mechanisms. With treatment still unknown, our attention is towards the eventual impact of complementary dietary interventions, synthesizing the recent knowledge of some edible mushrooms and preparations on Ménière’s disease, which is a lifelong condition that can develop at any age, but most commonly emerges between 40 and 60 years of age. It is demonstrated that the oral administration of a biomass preparation, with 3 g/day of the mushroom Coriolus versicolor for 2 to 6 months, on some 40 human Ménière’s disease patients reduced systemic oxidative stress and cellular stress response, decreased the number of crises and their duration, and the frequency of symptoms, improving the clinical grading of tinnitus severity.
