Unlike the human and canine forms of Cushing's disease, which most commonly affect the pars distalis region of the pituitary gland, equine Cushing's disease is a result of hyperplasia or adenoma formation in the pars intermedia. [2] This adenoma then secretes excessive amounts of normal products, leading to clinical signs.
Cushing's is an umbrella term for conditions caused by elevated cortisol and adrenocorticotropic hormone levels. Cushing's disease most commonly refers to pituitary-dependent hyperadrenocorticism, the most common condition of Cushing's syndrome, but 'Cushing's' is used to refer to all hyperadrenocorticism conditions.

The symptoms of Cushing's disease are similar to those seen in other causes of Cushing's syndrome. [5] Patients with Cushing's disease usually present with one or more signs and symptoms secondary to the presence of excess cortisol or ACTH. [6] Although uncommon, some patients with Cushing's disease have large pituitary tumors (macroadenomas).
Experts share signs and symptoms of Cushing syndrome, the condition with which Amy Schumer was recently diagnosed. The actress said it was brought on by having high doses of steroid injections.
An equine behaviourist said warning signs included ‘pinned ears, tense facial muscles, swishing tails or shifting weight’. An equine behaviourist said warning signs included ‘pinned ears ...
EMS shares similarities to pituitary pars intermedia dysfunction (also known as equine Cushing's disease), which also causes regional adiposity, laminitis, and sometimes insulin resistance. Treatment and management differ between the conditions, making it important to distinguish between the two.
Cushing's syndrome is a collection of signs and symptoms due to prolonged exposure to glucocorticoids such as cortisol. [4] [9] [10] Signs and symptoms may include high blood pressure, abdominal obesity but with thin arms and legs, reddish stretch marks, a round red face due to facial plethora, [11] a fat lump between the shoulders, weak muscles, weak bones, acne, and fragile skin that heals ...
Pituitary pars intermedia dysfunction, or Cushing's disease, is common in older horses and ponies and causes an increased predisposition to laminitis. Equine metabolic syndrome is a subject of much new research and is increasingly believed to have a major role in laminitis. It involves many factors such as cortisol metabolism and insulin ...
