Stephen L. Hauser is an acclaimed physician and neuroimmunologist who has spent his career performing cutting-edge research on multiple sclerosis (MS), a devastating brain disease that affects millions of people worldwide. His work has revolutionized our understanding of the genetics, immunology and treatment of MS, and led to the development of B cell therapies—the most effective therapy for all forms of MS and the only therapy currently in place for progressive MS patients. The Face Laughs While The Brain Cries is a riveting memoir that follows Dr. Hauser from his unorthodox upbringing among the colourful cast of characters responsible for his development into a tenacious and innovative researcher, to the life-changing medical breakthroughs he has made against extremely long odds. Along the way, readers will learn the incredible stories of many of his patients, whose bravery, strength, and optimism in the face of a debilitating illness were instrumental to the progress that has been made in the fight against MS. This heart-warming book, written in accessible prose and related with equal measures of humour, empathy, and excitement, is sure to inspire.
