title: Chapter 17: cognitive assessment in neurology.
abstract: Modern interests in cognitive assessment began with Franz Gall's early 19th century theory of mental organology and Paul Broca's reports in the 1860s on patients with focal brain injury and aphemia. These workers spurred interest in assessing delimited mental abilities in relation to discrete cerebral areas. With roots in experimental and educational psychology, the intelligence testing movement added assessment tools that could be applied to neurological patients. Early- to mid-20th-century landmarks were Alfred Binet and Theodore Simon's intelligence scale, Howard Knox's nonverbal performance tests, and the intelligence quotient conceived by Lewis Terman and refined by David Wechsler. Also developed during this era were Henry Head's Serial Tests for aphasic patients and Kurt Goldstein's tests for brain-injured patients with impairments in "abstract attitude" and concept formation. Other investigators have contributed procedures for the evaluation of language functions, memory, visuospatial and visuoconstructive skills, praxis, and executive functions. A further milestone was the development of short standardized cognitive instruments for dementia assessment. Within a neurological arena, the historical emphasis has been on a flexible, process-driven approach to the service of neurological diagnosis and syndrome identification. Advances in clinical psychology, neurology, and the cognate clinical neurosciences continue to enrich assessment options.
