It is twenty years since the first edition of this textbook of neurology was published. In this, as in the previous editions, it remains

the simplest, most compact, well-illustrated and clearly written textbook of neurology. It is most valuable and accessible for reading and reference, not only for neurologists but for all physicians.

The notable progress made in the last few years in neurology has been included in this revision. The chapter by Dr. David Wechsler on psychometric tests has been completely rewritten and changed to psychological diagnosis of personality disorders in organic brain syndromes. Descriptions of the diagnosis and treatment of many disease syndromes have been re-edited to accord with recently acquired knowledge. New syndromes and the chemotherapies (sulpha drugs and penicillin) have been included. The chapters on the neuroses and the history of neurology have been retained.
