[Neurodegenerative disorders of the central nervous system in horses].

The research article reviews the notable neurodegenerative diseases that occur in horses and mentions some cases reported to Utrecht Veterinary Faculty. It denotes the need for a better understanding of the causes of these disorders, pointing out the potential roles of vitamin E deficiency and certain mycotoxins.

Discussion of Neurodegenerative Diseases in Horses

• The paper delves into neurodegenerative diseases relevant to horses, including ataxia which can be associated with different conditions like static stenosis, dynamic stenosis, lesions in different parts of the central nervous system, horse herpesvirus infections, equine degenerative myeloencephalopathy, and cerebellar abiotrophy.
• It also touches on other diseases, such as equine motor neuron disease, equine dysautonomia (commonly known as grass sickness), postanesthetic myelomalacia, and leukoencephalomalacia (a condition affecting white matter in the brain).

The Role of Vitamin E and Mycotoxins

• The research mentions that the actual causes behind the neurodegenerative lesions uncovered in horse patients are not entirely clear. However, they suggest that vitamin E could play a role in some patients, possibly coinciding with other risk factors. Research findings suggest that vitamin E deficiency could potentially be linked to neurodegenerative disorders in horses.
• Another cause suggested in the article is the presence of a mycotoxin, a fungi-produced toxic compound, which is understood to interfere with myelin metabolism. This is particularly noted in relation to leukoencephalomalacia.

Observations from the Research

• The article describes the cases reported to the Utrecht Veterinary Faculty that involved patients from horses to Mongolian Przewalski horses, and even zebras. These cases seem to suggest that there can be mixed forms of some of these differentiated diseases.
• Though the article reviews the significant neurodegenerative diseases of horses, it makes clear the need for further research to fully understand their etiology and potentially find more effective treatments and preventative measures.
