Visual versus Verbal Working Memory in Statistically Determined Patients with Mild Cognitive Impairment: On behalf of the Consortium for Clinical and Epidemiological Neuropsychological Data Analysis (CENDA).

These results suggest that visual WM may be particularly sensitive to emergent illness compared to analogous verbal WM tests.
