Welcoming Museum Visitors with Unapparent Disabilities exploreshow international cultural organizations (i.e. museums, aquariums, art centers) serve individuals with mental health and neurodiverse challenges. Opening chapters present the status of mental health in society and the need for inclusive design. Organized by unapparent disability, the book includes: a medical definition of the condition as defined by the International Statistical Classification of Diseases and Related Health Problems 11th Revision (ICD-11) by the World Health Organization; a brief introduction to that condition; personal accounts of the condition and challenges faced when visiting a museum, exhibition, and/or participating in a program; and, global case studies which describe how the hidden disability was supported/addressed and lessons learned.
