This book covers Ehlers-Danlos and hypermobility syndromes with an emphasis on treatment of the parasympathetic and sympathetic (P&S) nervous system dysfunctions. Unfortunately, most EDS/HSD patients have been misdiagnosed and misunderstood by providers. EDS/HSD is a multisystem, multifaceted disorder that is poorly understood. The P&S manifestations and treatments are also poorly understood throughout the healthcare community. To this end the authors wish to teach providers and patients alike to reduce the life-long suffering from both the disorder and the marginalization.
