Cushing's triad, which includes bradycardia, hypertension (with widened pulse pressure), and a change in respiratory pattern, is seen in head injuries with increased intracranial pressure (ICP).
Cushing syndrome is a group of signs and symptoms caused by abnormally high levels of cortisol (hypercortisolism). Cortisol is produced by the outer layer of the adrenal glands, called the cortex.Cortisol is a steroid hormone that breaks down fat and protein and stimulates liver glucose production. Cushing disease, a form of Cushing syndrome, occurs in about 40% of cases and is the most common cause of excess endogenous cortisol production by the adrenal glands. 2  It is caused by a pituitary tumor (adenoma) that secretes ACTH.
