In my opinion idiopathic meniere is urban myth.
There is a cause for symptoms autoimmune & immune responses to pathogens
can be a cause.
Anxiety can trigger an autoimmune response
If I may interject an opinion, I agree with 1MW's statement. To elaborate, Meniere's disease represents a triad of symptoms described in the 19th century by French physician Prosper Meniere. Endolymphatic hydrops seems a far better term to help understand a common underlying problem.
As mentioned above, multiple conditions can generate the triad of symptoms that Dr Meniere described: tinnitus, vertigo, and hearing loss. The list includes autoimmune and immune responses to external stimuli. My personal experience suggests that food sensitivity is often responsible for these symptoms. Food sensitivity is not the same as a typical allergic response, mediated by histamine. Sensitivity to grains is quite common. Wheat, corn, cow-dairy, and soy products often produce symptoms.
I also agree that the fear response can trigger or exacerbate an immune system response. (The fear response includes anxiety, along with other negative emotions of fear, anger, frustration, guilt, shame, sadness, remorse, etc.) My experience suggests that children raised in a fear filled environment are far more likely to develop autoimmune disorders than those raised in an environment filled with love and support. A fearful environment for a child may include physical, emotional, or sexual abuse.
As a result of such early conditioning, it is as though the body's inner guards (immune system responses) are constantly hyper-vigilant, poised to attack any perceived threat from inside or outside the body. The attack response often becomes disproportionately large and inappropriate for the actual threat.
