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
