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

We have access to advanced imaging equipment, including MRI and CT/PET scans, cerebrospinal fluid analysis, and electrophysiology. We also have the capabilities to perform peripheral nerve and muscle biopsy and neurosurgery on the brain, spinal cord, and peripheral nerves.​

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