  • Summary

    In this chapter we will describe how Parkinson’s disease (PD) affects patients’ eye movements, both bedside and laboratory, preceded by brief review of the anatomo-physiological substrate of eye movements. We will provide a practical summary of how to use the eye movement examination to aid the differential diagnosis of the parkinsonian syndromes, in particular idiopathic PD from multiple system atrophy (MSA), progressive supranuclear palsy (PSP), and corticobasal syndrome (CBS). A sub-section will describe how deep brain stimulation (DBS) also influences eye movements in PD. Despite a plethora of eye movement laboratory studies in PD it is still relatively unknown what the eye movements of these patients are like in real life. Given that the eyes move in order to see better, does the akinesia of PD impose visual deprivation or delays during ecological whole-body movements?.

  • Dizzy patients are notoriously difficult to diagnose as doctors require knowledge spanning several subspecialties, including neurology, otolaryngology, internal medicine and psychiatry. This updated second edition integrates the essential information from these fields, providing advice that is both practical and accessible. Beginning with two jargon-free chapters on anatomy, physiology and examination techniques, the book follows a coherent structure organized according to clinical presentations, such as recurrent vertigo, positional vertigo and chronic dizziness. Each chapter is summarized with a table showing diagnoses and their key features, ensuring that the relevant differential diagnoses are readily available. Access to more than sixty online video clips is included, illustrating bedside findings from pathological nystagmus to specific balance problems. With practical advice offered for a range of difficult clinical situations, this comprehensive guide will enable any doctor to feel confident when confronted with dizzy patients.
