  • *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.
