The "glucocorticoid cascade hypothesis" for pathological ageing of the brain is supported by strong experimental data, but the clinical correlates are far less clear. The basal ACTH and cortisol secretion have been studied before and after the dexamethasone suppression test in patients in the early stages of clinically probable Alzheimer's disease and in controls, and the results were all normal. These findings do not support the hypothesis that the pathological brain ageing of Alzheimer's type is caused by hyperactivity of the pituitary-adrenal axis.
大脑病理性衰老的“糖皮质激素级联假说”得到了有力实验数据的支持,但临床相关性却远不那么明确。在临床可能为阿尔茨海默病早期的患者及对照组中,对地塞米松抑制试验前后的基础促肾上腺皮质激素(ACTH)和皮质醇分泌进行了研究,结果均正常。这些发现不支持阿尔茨海默病型大脑病理性衰老由垂体 - 肾上腺轴功能亢进引起这一假说。
