Note. The 7-day interval = 24-hr to day 8 assessment; 14-day interval = 24-hr to day 15 assessment; 30-day interval = day 15 to day 45 assessment; 44 day interval = 24-hr to day 45 assessment; 198 day interval = baseline to 24-hr (first repeat) assessment. SRT = Simple reaction time; CDS = code substitution-learning; PRO = procedural reaction time; MTH = mathematical processing; M2S = matching to sample; CDD = code substitution-delayed; SR2 = simple reaction time 2; GNG = go no-go; PS = processing speed; AT = attention; LN acc. = learning accuracy; WM = working memory; VERM = verbal memory composite; VISM = visual memory composite; VMS = visual motor speed composite; RT = reaction time composite.
