Comparing Mattis Dementia Rating Scale--initiation/perseveration subset and frontal assessment battery in stroke associated with small vessel disease.

Forty-two controls and 32 patients with stroke associated with small vessel disease (SSVD) were administered the Mattis Dementia Rating Scale Initiation / Perseveration subset (MDRS I/P) and Frontal Assessment Battery (FAB). Both tests showed comparably good ability in Receiver Operating Characteristics curves analysis (AUCMDRS I/P=0.887; AUC FAB=0.854, p=.833) in discriminating between controls and patients and correctly classified over 78% of subjects. Verbal fluency and motor programming contributed most to the discriminating power in the two tests. The MDRS I/P and FAB are useful in discriminating between controls and SSVD patients in a hospital setting.
