Abstract Objectives: Traditional mental status screens have limited sensitivity in detection of focal brain damage and are particularly insensitive to right hemisphere stroke (RHS). Addition of a simple measure of constructional ability, clock drawing, should enhance the sensitivity of the Modified Mini-Mental State Exam (3MS) in RHS. The relation between the 3MS-clock drawing screen and functional outcome in RHS was also examined. Design: Logistic regression analysis (Study 1) with cross validation on an independent sample (Study 2). Setting: Inpatient medical rehabilitation. Patients: Study 1: 32 acute RHS patients (mean age 75.2yrs) and 35 age- and education-matched healthy controls. Study 2 (cross-validation): 32 acute RHS patients (mean age 72.8yrs) and 36 matched healthy controls. Outcome Measures: 3MS, clock drawing, and Functional Independence Measure scores. Results: The 3MS-clock screen accurately distinguished RHS patients from controls. The clock drawing was a valuable and unique addition to the 3MS. RHS patients who were impaired on the 3MS-clock drawing screen had significantly worse FIM scores at discharge than RHS patients who were not impaired on the cognitive screen. Conclusion: Clinicians can enhance the sensitivity of their brief mental status examination of RHS patients, in addition to obtaining useful prognostic information, by including a clock drawing task in their screen.
