Severe cases can lead to changes in mare’s estrus cycle, lethargy, depression, or neurological problems including a head tilt.
Can Cushings cause neurological symptoms horses?
In severe cases, Cushing’s disease can cause neurologic disease. Classic clinical signs in horses include a long, curly hair coat, a cresty neck, abnormal fat deposits and poor shedding habits. Some older horses lose muscle mass. Most afflicted horses are older, but younger horses can develop Cushing’s disease as well.
Can Cushing’s disease cause neurological problems?
In women, there may be increased growth of facial and body hair, and menstrual periods may become irregular or stop completely. Neurological symptoms include difficulties with memory and neuromuscular disorders.
How does Cushing’s syndrome affect the nervous system?
Chronic exposure to supraphysiologic levels of glucocorticoids in Cushing’s syndrome is associated with anatomical brain changes and an increased prevalence of psychiatric diseases, cognitive impairment, mood alterations, and sleep disturbances [1-5].
Can Cushings in horses cause seizures?
Weight loss from muscle wasting gives the affected horses a sway-back/ewe-necked appearance but fat restribution causes abdominal enlargement and possibly bulging of the hollow above the eyes. If the pituitary gland enlarges significantly it can press on the optic nerves and the brain and cause blindness and seizures.
What is the most common neurological conditions in horses?
Many diseases can affect horses’ central nervous systems, but four of the most common disorders are cervical vertebral stenotic myelopathy (CSM), equine protozoal myeloencephalitis (EPM), equine degenerative myeloencephalopathy (EDM), and equine herpesvirus-1 myeloencephalopathy (EHM).
Does Cushings cause brain damage?
Brain structural abnormalities related to Cushing’s syndrome have been repeatedly found, including smaller hippocampal volumes, enlarged ventricles, and cerebral atrophy3.
What can be mistaken for Cushing syndrome?
Cushing’s syndrome may be mistaken for other conditions that have many of the same signs, such as polycystic ovary syndrome or metabolic syndrome. Your doctor will first want to rule out other conditions. Diagnosis is based on your medical history, a physical exam, and lab tests.

How does cortisol affect the nervous system?
Cortisol, the primary stress hormone, increases sugars (glucose) in the bloodstream, enhances your brain’s use of glucose and increases the availability of substances that repair tissues. Cortisol also curbs functions that would be nonessential or harmful in a fight-or-flight situation.
How does Prascend work in horses?
Prascend® is a medicine licensed to treat the clinical signs associated with Equine Cushing’s disease in horses. It contains the active ingredient pergolide. Prascend® works by mimicking the action of dopamine and therefore regulating the production of hormones from the pituitary gland.
What is the difference between Cushing’s disease and Cushing’s syndrome?
What is the difference between Cushing disease and Cushing syndrome? Cushing disease occurs when Cushing syndrome is caused by an ACTH-producing pituitary tumor, whereas Cushing syndrome is the set of symptoms that results when there is a surplus of cortisol in the body.
Are seizures part of Cushing’s disease?
While Cushing’s Disease (also known as hyperadrenocorticism) is not typically a direct cause of seizures, some of the circumstances surrounding the condition can lead to seizures. In most cases, Cushing’s Disease is caused by a lesion in the pituitary gland at the base of the brain.
Is there an alternative to Prascend for horses?
In horses that simply refuse to eat pergolide, or in the small percentage of cases that do not respond well to treatment, then there is an alternative. Instead of using a drug that aims to reduce ACTH secretion by the pituitary gland, we instead use a drug called Trilostane (marketed as Vetoryl).
What is life expectancy with Cushings?
Cushing’s disease is fatal without treatment; the median survival if uncontrolled is about 4.5 years, Melmed said. “This truly is a metabolic, malignant disorder,” Melmed said. “The life expectancy today in patients who are not controlled is apparently no different from 1930.”
What are signs of neurological problems in horses?
Lack of coordination, weakness or paralysis of the hind limbs, muscle twitching, impaired vision, head pressing, aimless wandering, convulsions, circling and coma are some of the severe neurologic effects. Horses typically have non-neurologic signs, too, such loss of appetite and a depressed attitude.
What are 4 neurological symptoms?
Examples of symptoms include paralysis, muscle weakness, poor coordination, loss of sensation, seizures, confusion, pain and altered levels of consciousness.
What can cause neurological problems in horses?
Equine neurological disorders are typically caused by an infection or a malformation in the spinal column. Botulism: An infection caused by bacteria that can be found in poorly stored or moist fodder that produces a toxin when consumed, leading to an inability to swallow, hold the head up, and muscle weakness.
Can the effects of Cushings be reversed?
