predisease

Adjective

 * 1) Of or relating to a predisease (such as prediabetes or prehypertension), as with predisease states or predisease stage.
 * 2) Before a disease began, as with predisease cognitive performance as a baseline in dementia or predisease motor function as a baseline in multiple sclerosis.

Noun

 * 1)  A condition, albeit consisting of only one or two, that is identifiable as, or believed to be, a subclinical prelude to a disease, with greatly increased predisposition thereto (for example, prediabetes or prehypertension); the operational definition of such a state or the clinical value of asserting it may be contentious (as with purported preobesity).
