  1. Thresholds are listed in order of decreasing difficulty: the more difficult thresholds are shown at the top and the easier ones at the bottom. Items are identified by their item number, followed by their threshold number (Example: PDQ3.2 represents PDQ item 3, 2nd threshold). Abbreviations: ccont: clock contour; chand: clock hand; corbw: corsi backwards; cubes: copying a cube; date: knowing the date; day: knowing the day of the week; digbwA: digits backwards (form A); digbwB: digit backwards (form B); digf: digit forward ; flanAcon: flanker test (form A), congruent reaction time; flanA: flanker test (form A) flanker effect; flanBcon: flanker test (form B) congruent reaction time; Fflu: F fluency; mon: month; ser7A: serial 7 (form A); ser7B: serial 7 (form B); trailA: short trail (form A); trailB: short trail (form B); mW1-mW5: MoCA memory words recall, 1–5; name2-3: name 2nd and 3rd object from MoCA; place: knowing the place; tapa: MoCA tap on letter a
