Over 12 million people with epilepsy have seizures that cannot be controlled by antiepileptic drugs. The term "drug-resistance" is abundantly used in the epilepsy literature but the definitions proposed differ considerably. It is used indifferently in a number of different settings: as a criterion for selection of patients eligible for new antiepileptic drug trials, for the selection of surgical candidates, for the design of epidemiological studies, for the design of studies on quality of life, for the definition of the epileptic encephalopathies (in comparison to more benign epilepsy syndromes), to mention but a few. As a result, available studies are usually not comparable and referral to epilepsy specialists is unacceptably delayed. The volume includes several focused chapters on all issues relating to drug-resistance and offers the basis for a consensus on a clinically meaningful core definition.

Book & DVD. With its many colour illustrations, this book provides a valuable overview of this fascinating discipline. Stereotaxy is a neurosurgical technique which consists in using the co-ordinates obtained by placing electrodes in a patient's brain to "map" in precise detail the part of the brain causing a particular disease, providing the neurosurgeon with the detailed information required for a more targeted surgical intervention. The book first provides background information on stereotaxy, discussing the methods and techniques used in stereotaxy applied to epilepsy surgery. Its many illustrations of surgical interventions and of the materials and methods used when implanting the electrodes give the reader a very clear view of the sequence of events involved. This is a true guide to stereotaxy and neurosurgery. The DVD features video sequences and 51 clinical cases!

Having appeared in the 1930s in Montreal, standardised neuropsychological evaluation has become an essential tool in the clinical diagnosis and evaluation of surgical epileptic patients. Nevertheless, despite great progress over the last 20 to 30 years in the diagnosis and medical treatment of epilepsy, clinical neuropsychology still remains largely associated with surgical epilepsy, particularly surgery of the temporal lobe. Clinical neurology has still not managed to clear a way in the daily practice with patients with all types of epilepsy despite significant advances in cognitive neuroscience and a large number of clinical studies on epilepsy and cognition. How is it that there are only rarely major advances in the field of clinical neuropsychology? It has long been time for this question to be asked, and for an attempt to be made to bring about changes. This was the aim of the Toronto workshop and the result of this book. Every approach was debated, providing important elements to reflect on and allowing a great forum for exchanges. This book includes the communications from the main participants and comments from some others on specific subjects.
