Subject characteristics and test results for each group.

Means are given with standard deviations in parentheses. AD: Alzheimer’s disease, FTLD: frontotemporal lobar degeneration, CDR: Clinical Dementia Rating Scale, GLM: General Linear Model, WMS: Wechsler Memory Scale, LM: Logical Memory 1: immediate, 2: delayed, FR: forgetting rate), VR: Visual Reproduction 1: immediate, 2: delayed, FR: forgetting rate). For further analyses see text.1The high standard deviation in this test measure was due to the fact that one AD patient recalled more information in the delayed compared to the immediate recall, although on an extremely low level of performance (one item in the immediate and four items in the delayed recall, thus resulting in a forgetting rate of −300).
