*Tests used for each domain: Global Screening measure=Dementia Rating Scale 2; Verbal List Learning and List Delayed Recall=AVLT or CVLT-2-SF; Visual Learning and Visual Delayed Recall=Wechsler Memory Scale III/IV, Visual Reproduction Immediate and Delayed Recalls; Confrontation Naming=Boston Naming Test; Lexical Fluency=Controlled Oral Word Association Test; Semantic Fluency=Category Fluency; Visuospatial Construction=Rey-Osterrieth Complex Figure–Copy Condition; Auditory Working Memory=Wechsler Adult Intelligence Scales III/IV, Digit Span; Visual Attention/Processing Speed=Trail Making Test A; Set Shifting=Trail Making Test B; Cognitive Inhibition=Stroop Colour/Word Condition.
†Test scores were transformed to scaled scores; within normal limits=number of patients with scaled scores ≥9, mildly low=number of patients with scaled scores 6–8, impaired=number of patients with scaled scores ≤5.
‡Six patients completed the CVLT-2-SF and 21 completed the AVLT as tests of list learning and memory.
§Three patients did not complete tasks within the required time limit and were considered to have impaired performance on this measure.
