Clinical Neurological Examination and Localization 1st ed. 2021

Bedside Neurological examination is an important tool in diagnosing neurological disorders. Despite significant advances in the investigations available for diagnosing neurological disorders bedside neurological examination remains the cornerstone in diagnosing neurological disorders and should not only be conducted prior to the investigations but should be actually be utilized to plan the appropriate investigations. The ebook provides a focused account of various aspects of the neurological examination leading to clinical localization and hence obtaining the neurological diagnosis. It includes topics like how to obtain an appropriate neurological history’, ‘higher mental system examination’, examination of speech and various cranial nerves, and examination of other systems including motor system, sensory system, reflexes, cerebellar, and autonomic nervous system. The ebook also includes certain interesting topics like ‘neurological examination of the unconscious patient ‘and ‘tricks and tips of neurological localization. The ebook is easy to read and memorize due to multiple self-explanatory illustrations and important aspects being highlighted in bulleted format. The book will be of extreme help for MD and DNB students of Internal Medicine as well as DM and DNB students of Neurology and DNB and MCH Neurosurgery students, hence covering a fairly large readership base. It will also be read by practicing Internal medicine physicians, neurologists, and neurosurgeons who may want to revise the basics and tricks of neurological examination and localization.

About the Author

Dr. Vinit Suri is one of the most eminent neurologists in India with more than 30 years of experience in the field. He is a graduate of University College of Medical Sciences, Delhi University, and stood first in the Final MBBS examination with several gold medals to his credit and obtained his D.M. Neurology from G.B.Pant Hospital in 1992. He has been involved in teaching graduate and postgraduate students for the last 30 years and this is something very close to his heart. He is extremely sought after by his students for teaching neurological examination methods and skills of localization in a simple and easy-to-understand manner.

He has been working at Indraprastha Apollo Hospital, New Delhi as  Senior Consultant Neurologist and Coordinator of the department since 1996 and has been a pioneer in spearheading the Stroke Thrombolysis program in India.
He has served the Indian Stroke Association as the Secretary, Treasurer, and President and is the current President of the Delhi Neurological Association.


Neurological evaluation is similar to solving a complex mathematical equation. It is similar because neurological localization is extremely accurate
when components of the equation are selected appropriately. This exercise involves the accurate selection of the components of the equation from the history and elicitation of appropriate clinical signs as well as understanding the “neurological language” so as to arrange the components appropriately. An experienced neurologist can take an appropriate though detailed and focused history and conduct an appropriate and focused neurological examination and resulting in localizing the lesion within a few minutes when the inexperienced beginner may not get anywhere even after spending hours.

In this era of sophisticated neurological investigations including MRI, PET MRI, and functional MRI, electrophysiology, and genetic and serological markers clinical localization continues to be important and relevant and should not only precede these investigations but also should guide the diagnostic evaluation process.

This book is planned to provide a concise though a focused overview of methods of neurological examination enabling a focused clinical approach for localization in patients with neurological disorders.

Important components of the neurological diagnosis include:

1. Site of lesion:
(a) Central or peripheral nervous system with specific localization site—determined by localization from both history and clinical examination.
2. Etiology of lesion:
(b) Determined predominantly from the history with clues from:
I. Onset-acute, subacute, or chronic
II. Course of the illness-monophasic, relapsing, progressive, or spontaneous improvement
III. Other comorbidities and family history
IV. Therapeutic responses and failures
Differential Diagnosis in order of priority is then prepared using the components of the SITE of lesion and ETIOLOGY at that site.
