This is a pocket-sized ready-reference to neurology. Organised from A to Z, the content consists of a series of entries, each one describing, in a readable and accessible style, an aspect of neurology. This ranges from providing overviews of major groups of diseases (e.g. the dementias) to more detailed coverage of specific disease categories (e.g. Alzheimer's disease). Specific neurological conditions are described according to a very structured template covering the definition of the condition, its clinical features, investigation, pathogenesis and treatment, finishing with a small number of relevant and up-to-date references. In addition, there are hints about differential diagnosis with extensive cross referencing between entries. This will become an essential resource for those undertaking training in neurology, will be of interest to those with interests closely allied to neurology (e.g. neurosurgery, neurorehabilitation) as well as providing a reference source for generalists looking for a readable synopsis of neurological conditions.
