Wobbler disease or wobbler's syndrome is a broad category of cervical disorders in the horse, including the conditions listed above, as well as equine wobbles anemia and cervical vertebral myelopathy, spinal cord compression (sometimes referred to colloquially among horse owners as "cervical arthritis" due to the arthritis that accumulates in facets).
Equine protozoal myeloencephalitis in various stages. Equine protozoal myeloencephalitis (EPM) is a disease that affects the central nervous system of horses.It is caused by a protozoal infection that is brought about by the apicomplexan parasites Sarcocystis neurona or Neospora hughesi.
Neospora hughesi is an obligate protozoan apicomplexan parasite that causes myelitis and equine protozoal myeloencephalitis (EPM) in horses, and has only been documented in North America. [1] EPM is a neurological disease from lesions in the spinal cord, brain stem, or brain from parasites such as N. hughesi or Sarcocystis neurona. [2]
Cervical vertebral stenotic myopathy (Wobbler disease): compression of the spinal cord in the cervical (neck) region results in lameness, ataxia, and change in gait, especially in the hind legs, and neck stiffness or pain.
After the conus medullaris (near lumbar vertebral levels 1 (L1) and 2 (L2), occasionally lower), the spinal canal contains a bundle of nerve fibers (the cauda equina or "horse-tail") that branches off the lower end of the spinal cord and contains the nerve roots from L1–L5 and S1–S5. The nerve roots from L4–S4 join in the sacral plexus ...
In horses, the disease often progresses gradually and includes clinical signs such as ataxia. In some horses mild clinical signs may herald a rapidly progressive disease course. The vital signs of infected horses are usually normal during physical examination, although thinning and mild depression may be present.
On Friday, March 27, 2009, at 11:13 pm, Alysheba was euthanized at the Hagyard Equine Medical Institute. "Due to a chronic degenerative spinal condition that led to ataxia and instability, Alysheba fell in his stall yesterday, injuring his right hind femur," said Kathy Hopkins, the Horse Park's director of equine operations. "Complicated by his ...
In 2008, a genetic ataxia blood test developed to test for 12 types of SCA, Friedreich's ataxia, and several others. However, since not every SCA has been genetically identified some SCAs are still diagnosed by neurological examination, which may include a physical exam, family history, MRI scanning of the brain and spine, and spinal tap.
