Companion Animal Practice
Common cranial nerve disorders in dogs and cats
  1. Jacques Penderis

    Jacques Penderis graduated from the University of Pretoria (Onderstepoort) in South Africa in 1993. After a spell in small animal practice, he completed an internship at the Royal Veterinary College and a residency in neurology at Glasgow. In 1998, he moved to the Animal Health Trust (AHT), where he latterly worked as head of the neurology/ neurosurgery unit. He is currently studying for a PhD at Cambridge, after which he will return to the AHT to develop a genetic and molecular neurology research programme. He is a diplomate of the European College of Veterinary Neurology and an RCVS and European recognised specialist in neurology.

1. CN I to IV and CN VI


CONSIDERING the rarity and complexity of many neurological disorders, it is not surprising that neurology cases are often referred to specialist centres. However, this is certainly not the situation with regard to cranial nerves disorders, the majority of which can be readily identified and managed in practice. Initial assessment of these conditions is both quick and simple, and does not require any expensive or specialised equipment. The aim of this series of articles is to discuss the assessment of cranial nerves and detail their common disorders, either as a refresher for those already proficient in their management or as an introduction for those less experienced in clinical neurology. Part 1 considers the nerves involved in vision (CN II, III, IV and VI) and olfaction (CN I); Part 2, to be published in the May issue of In Practice, will discuss the trigeminal (CN V) and facial (CN VIl) nerves (which primarily supply sensation and motor function to the face); while Part 3, to be published in the June issue, will describe vestibular disease and deafness (CN VIII), as well as the remainder of the cranial nerves (CN IX to XII).
