Other immune and neuro-immune diseases
There are several conditions that are not known to be comorbid with ME but where our understanding of the underlying pathophysiology might inform approaches to researching all immune diseases, or where treatments may have applications across diagnosis.


 * Common variable immunodeficiency (CVID)
 * Endometriosis
 * Idiopathic intracranial hypertension
 * Multiple sclerosis
