This chapter defines emerging disabilities; explores medical, psychosocial, and vocational implications of emerging disabilities that distinguish them from traditional disabilities; and provides demographic characteristics of individuals who are most vulnerable to acquiring emerging disabilities. It examines some social and environmental trends that have contributed to the development of emerging patterns and types of disabilities including advances in medicine and assistive technology, globalization, climate change, poverty, violence and trauma, the aging American populace, and disability legislation. Psychological and physical trauma from warfare, violent crime, intimate partner violence, and youth violence can result in permanent physical, cognitive, and psychiatric disabilities. Diagnostic uncertainties, misdiagnoses, and skepticism on the part of medical providers are frequently associated with emerging disabilities. Women also represent a population that is at an increased risk of acquiring emerging disabilities and chronic illnesses. Rehabilitation systems are still not fully prepared to address the multifaceted needs of individuals with emerging disabilities.
