Book excerpt: Clinical case studies have long been recognized as a useful adjunct to problem-based learning and continuing professional development. They emphasize the need for clinical reasoning, integrative thinking, problem-solving, communication, teamwork and self-directed learning – all desirable generic skills for health care professionals. This book is a teaching tool that bridges the gap between textbook information and everyday experience of clinicians 'in the trenches'. Leading practitioners bring a practical approach to these complex conditions, highlighting specific areas of diagnostic uncertainty in evaluation and treatment. Each case is taken from real-world clinical practice and reviews the diagnostic and treatment process in a systematic manner, identifying common challenges and potential pitfalls. This concise and useful guide in the Common Pitfalls series provides a step-by-step guide for everyday clinical practice, invaluable to anyone dealing with cerebrovascular disease on a front-line basis. The intended readership is trainees and non-specialist practitioners in neurology, stroke medicine, and neurosurgery.
