Abstract

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).
