Full Definition
The fourth edition of the Wechsler Memory Scale, a comprehensive standardized neuropsychological instrument designed to assess various aspects of memory function in individuals aged 16-90 years. The WMS-IV evaluates immediate and delayed recall across different memory domains including auditory, visual, and working memory. It provides age-corrected normative scores and is commonly used in cognitive neurology to diagnose memory disorders, track cognitive decline, and assess treatment efficacy. The battery includes subtests for logical memory, visual reproduction, verbal paired associates, and spatial addition, among others. Results help differentiate between normal aging, mild cognitive impairment, and dementia.
Usage
Usage note: Distinguish from WAIS-IV (intelligence test) and earlier WMS editions.
