Tropical neurology refers to those diseases of the nervous system which prevail in between the Tropics of Cancer and Capricorn. Developments in speed and ease of travel and globalisation of economy have resulted in large scale migration rendering the boundaries of tropical regions less distinct. Wars, famines, natural disasters and economic sanctions have added to the problem of infection and aggravated the preexisting nutritional deficiency disorders in many tropical countries. This book is aimed at residents, practicing physicians, health workers and physicians from western countries who are visiting the tropical countries.
