Areas of Expertise
We are one of the few veterinary hospitals in the US with a dedicated large animal neurologist. One of five double-boarded large animal neurologists in the country, Dr. Johnson and her team is world-renowned for her expertise in neurologic disease, including neurodegenerative conditions (eNAD/EDM), neck problems, EPM, and Lyme neuroborreliosis. The neurology team closely collaborates with Sports Medicine and Surgery clinicians to provide comprehensive care.
Some common causes of neurologic disease in horses include:
- Equine Protozoal Myeloencephalitis (EPM)
- Cervical Vertebral Malformation/Cervical Vertebral Instability (CVM/CVI), also known as “Wobbler syndrome”
- Neurodegenerative diseases (eNAD/EDM)
- Neurologic Lyme disease (neuroborreliosis)
- Traumatic brain or spinal cord injury
- Temporohyoid osteoarthropathy (THO)
- Equine Herpes Myeloencephalopathy (EHM)
- West Nile Virus (WNV)
- Other viral encephalitis
- Headshaking
- Seizure disorders
Diagnostic services include:
- Complete neurologic examination
- Standing robotic CT of the head and neck
- Radiography
- Myelography
- Ultrasound
- Cerebrospinal fluid analysis (“Spinal tap”)
- Muscle biopsy
- Electromyography (EMG)
- Brainstem auditory evoked response (BAER)
- Behavioral video monitoring
- Ultrasound-guided articular process joint injections
