Core Principles of Acute Neurology is a series of short volumes that handles major topics not found in sufficient detail elsewhere and provides useful context. Solving Critical Consults provide practical information on how to evaluate complicated neurology consults in the ICU. The diagnosis and management of neurologic complications of acutely ill hospitalized patients remains challenging. The modern intensive care unit is a different place with different patients, and consultants may require a specific expertise in handling complications associated with critical illness. Some of these requests for consultation include not only diagnosis of the neurologic state, but also assistance with management at all levels. Prognostication in devastating situations or when the critical illness has come under control is a common request.
