Wechsler Memory Scale (WMS)

The Wechsler Memory Scale (WMS) measures various memory functions in people aged 16-90 and is the most commonly used memory scale for adults. The original WMS was first introduced in 1945 with the latest edition being the WMS-IV introduced in 2009. The WMS is frequently used along with the Wechsler Adult Intelligence Scale (WAIS). The WMS is used to determine memory function and can diagnose memory abnormalities as an effect of dementia or neurological disorders.

Different types of memory are assessed using the WMS, including visual, visual working, auditory, immediate and delayed memory.
