Dementia screening batteries often fall short on measures of executive functioning. The Weigl Color Form Sorting Test (WCFST) is a candidate for inclusion in such batteries, but can be insensitive to mild disturbance. The WCFST consists of 12 colored geometric shapes and requires the patient to sort the pieces by color or form, and then shift to the other sorting principle unassisted. We created a modified version of the WCFST (the Weigl-R) with increased conceptual complexity by adding two stimulus dimensions (texture and central shapes). The range of scores was also increased by adding the extent of examiner assistance required to achieve a correct sort, ability to verbalize conceptual strategy, and number of perseverations. We administered the Weigl-R to a group of 30 patients with mixed dementias, 34 adults with cognitive impairment without dementia, and 21 healthy controls. The new measure discriminated well between healthy controls and older adults with either cognitive impairment without dementia, or dementia. The Weigl-R may be a useful adjunct to brief dementia batteries but requires further validation.
