Classic CAH results in impaired cortisol production and consequently elevated ACTH concentrations leading to chronic adrenal stimulation with strongly elevated adrenal steroid precursors before the enzymatic defect. In contrast to other forms of adrenal insufficiency, some untreated classic CAH patients seem to have less cli...
