What are Invisible Diseases or Disabilities?

Over a billion people are estimated to live with some form of disability, and an estimated 40% have medical conditions are not apparent to others-invisible diseases. Examples include chronic pain disorders, mental health issues, substance use disorders, visual or auditory impairments, and learning disabilities. Mental disorders are particularly common, affecting more than 50% of adults in middle- to high- income countries at least once within their lifetime. And rates of mental health issues are rising, particularly among young people. There is often significant stigma attached to disclosing a disability, and despite an increased utilization of health care services, substantial gaps in access remain. These include treatment costs, transportation, limited service availability, physical barriers, and in some cases, health care providers that are unable or unwilling to provide care, due to lack of understanding or knowledge.
