When Dr. Richard Horowitz moved to the Hudson Valley over a decade ago to start his own medical practice, he didn’t know that he would be jumping into the centre of one of the fiercest, most heated medical disputes being waged today. The ongoing debate over Lyme disease as a chronic illness has made it difficult for sufferers to find care, as doctors are in many cases unable or unwilling to diagnose it. This is how once-treatable infections can become chronic, causing disabling conditions that may never be cured.

In a field where the number of cases is growing each year and answers remain elusive, Horowitz has made extraordinary progress. His plan represents a paradigm shift, without which, he argues, the suffering will continue. In this book, Horowitz breaks new ground with a 16 Point Differential Diagnostic Map, the basis for his Lyme treatment plan, and an overarching approach to treating all chronic illness. He introduces MSIDS, or Multi-Systemic Infectious Disease Syndrome, a new lens on chronic illness that may prove to be an important missing link. And he covers in detail Lyme's leading symptoms and co-infections, including immune dysfunction, sleep disorders, chronic pain and neurodegenerative disorders. This book is an all-in-one source for patients of Lyme and other chronic illnesses to identify their own symptoms and work with their doctors for the best possible treatment outcome.
