Most of these patients initially present to non-neurologists. Mastering clinical skills and examination is essential in order to localise the most probable neuroanatomical site of the patient's problem. This will enable the physician to order a focused investigation and request appropriate consultations. However, exposure to patients with neurological disorders is limited during training due to various reasons. This book is therefore written to serve non-neurologist who are expected to encounter patients with neurological problems on a day to day basis
