Cushing's Triad in ICP: Pathophysiology, Mnemonic,

2021-5-21 Cushing’s triad is the manifestation of Cushing reflex (also referred to as the Cushing effect, the Cushing reaction, the Cushing’s phenomenon, or Cushing’s Law) – physiological nervous system response to increased intracranial pressure. Cushing’s triad is also known as the brain herniation triad.

Moreover, there are observations that suggest that brain centers superior to the hypophysiotropic area of the hypothalamus are involved in the pathophysiology of Cushing's disease. This concept has led to the discovery of neurotropic drugs that are able to induce complete remission of Cushing's syndrome in a cerain percentage of patients.

2016-4-22 Cushing's disease (CD) is the result of excess secretion of adrenocorticotropic hormone (ACTH) by a benign monoclonal pituitary adenoma. The excessive secretion of ACTH stimulates secretion of cortisol by the adrenal glands, resulting in supraphysiological levels of circulating cortisol.

Cushing Reflex - StatPearls - NCBI Bookshelf

2021-3-31 The Cushing reflex (vasopressor response, Cushing reaction, Cushing effect, and Cushing phenomenon) is a physiological nervous system response to acute elevations of intracranial pressure (ICP), resulting in Cushing’s triad of widened pulse pressure (increasing systolic, decreasing diastolic), bradycardia, and irregular respirations.
