Twenty-five years ago, the field of neuropsychology was well established in North America, Europe, and Australia, with less presence elsewhere. This article discusses the development of neuropsychology over the last 25 years in other regions. Method: The growth of neuropsychology in Asia, Africa, the Middle East, Central and South America, and New Zealand is reviewed. Sources drawn on include a 2016 edition of The Clinical Neuropsychologist describing the practice of neuropsychology in 18 countries; papers on the profession of neuropsychology in Latin America (Arango-Lasprilla, Stevens, Paredes, Ardila, & Rivera, 2016), the history of neuropsychology in Asia (Lee, Wang, & Collinson, 2016), and neuropsychology in Central America (Judd, 2017); INSNET; and personal communications. Conclusions: There has been tremendous variability in the development of neuropsychology across these regions over the last 25 years. Obstacles to the growth of neuropsychology have included economic constraints on health care provision, limited availability of appropriate assessment and treatment methods, linguistic diversity and illiteracy, stigma toward and/or lack of awareness of neuropsychological disorders, lack of graduate training and clinical supervision, absence of accreditation of neuropsychologists as a clinical profession, poor pay, and diminished visibility of the field within the regional culture. Despite these obstacles, neuropsychological research and practice is establishing itself in these regions and has grown significantly over the last quarter century. Major challenges remain in establishing awareness of the significance of and developing culturally appropriate methods of assessing and rehabilitating cognitive aspects of brain disorders, training programs, recognition as a profession, and dedicated funding for neuropsychology positions.
