Our neurology service evaluates, diagnoses, and treats large animal patients with a broad array of diseases that either primarily or secondarily affect the nervous system.

If your animal is experiencing neck or back pain, issues with balance, muscle atrophy, weakness, tremors, difficulty swallowing, deafness or blindness, a neurological examination might help to identify and diagnose your animal's potential disorder.

In addition to a range of diagnostic capabilities, we also have access to advanced imaging equipment, including the 4DDI Equimagine robotics-controlled imaging system.

About Dr. Johnson:

One of only five veterinarians in the world to be board-certified in both large animal internal medicine and neurology, and one of only two veterinarians practicing large animal neurology in the United States, Dr. Johnson has been a clinician at New Bolton Center since 2007 and was appointed to the faculty as assistant professor of large animal internal medicine and neurology in 2011.

As a neurologist, Dr. Johnson focuses on the diagnosis and treatment of diseases affecting the nervous system such as cervical vertebral (neck ) problems, also known as Wobbler syndrome, equine protozoal myeloencephalitis (EPM), and neurologic Lyme disease (neuroborreliosis).

Dr. Johnson received her veterinary degree from Cornell University, where she also completed a residency and became board-certified in large animal internal medicine in 2007.  After joining New Bolton Center as a lecturer in 2007, she completed a second residency in neurology at the University of Pennsylvania, becoming board-certified in neurology in 2011.

Some common causes of neurologic disease include:

  • Equine Protozoal Myeloencephalitis (EPM)
  • Cervical Vertebral Malformation/Cervical Vertebral Instability (CVM/CVI), also known as “Wobbler syndrome”
  • Neurologic Lyme disease (neuroborreliosis)
  • Trauma
  • Degenerative myeloencephalopathies
  • Equine Herpes Myeloencephalopathy (EHM)
  • West Nile Virus (WNV)

Appointments may be made by the owner, trainer or referring veterinarian.

Please call 610-444-5800 to make an appointment with Neurology.
