It is a great pleasure to write this foreword for Practice Pearls in Neurology, Series III. This is indeed a real collection of pearls. Neurological manifestations of systemic disorders are common. Renal dysfunctions are commonly associated with acute neurological syndromes and vice-versa. These have been highlighted as well. Neuro ophthalmology with approach to visual loss is written well. Optical coherence tomography (OCT) is gaining importance particularly in neurological practice and has been dealt with in detail. Idiopathic intracranial hypertension is more often dealt with by neurologists than neuro surgeons and the topic has received the attention it deserves. The cranial nerve conditions—Trigeminal Neuralgia and Bell's Palsy have been described with attention devoted to the complex anatomy and physiology of these two nerves. Practical management of these two conditions covering all aspects has been appropriately highlighted. It is beneficial to undergraduates, postgraduates and consultants to read the ‘Approach to Brachial Plexopathies’ which describes the applied anatomy, clinical manifestations, electro physiology and treatment including surgical approach. The dilemmas in anticoagulant therapy in neurology have been controversial. These have been dealt with clearly.

The overwhelmingly positive response to the first two books in the Series of Practice Pearls in Neurology has been the stimulus for the compilation of this final volume. Continuing to abide by the same principles which served us well in the earlier volumes, we have selected a wide range of topics with immense practical value to complete this series. As with the earlier volumes in this series, the expertise and experience of the faculty shines through each chapter. We are profoundly grateful to all the faculty members for their contribution to the successful realization of our goal of completing this series within specified timelines. It is our hope and belief that this final volume will round off this series covering many poorly charted areas in the neurological map and be of abiding use and value to the practitioners and students of neurology. We are grateful to Jaypee Brothers Medical Publishers (P) Ltd for their seamless guidance and help in bringing out these three series. Without the continued and selfless support of our families, this endeavour would not have fructified.

Practice Pearls in Neurology has been conceived and executed as a unique compilation of the topics elaborated in the annual seminars which go by the same name. These seminars have been conducted over the past three years and will be continued in the years to come. The abiding principle of these day long seminars have been to present commonly encountered (but seldom dealt with in standard books in a practically useful manner) conditions, in such a way as to help the novice as well as the adept. The presentations are aimed at focusing on knowledge or experience crystallized over the years into valuable pearls of wisdom pertaining to the topics under consideration.
