Results of the neuropsychological assessment on day 18 after intoxication. Test parameters are depicted as z-scores stratified for age and education. Negative values indicate worse performance compared to the normative sample. Performances within the dotted area are within 1 SD from the mean of the normative sample (z = 0 +/− 1). Test parameters are grouped into broader cognitive domains (in bold and italics). Mild-to-moderate deficits in tests for cognitive processing speed, verbal learning and memory as well as efficiency of visual learning were observed. MoCA = Montreal Cognitive Assessment; RAVLT = Rey Auditory Verbal Learning Test; BVMT-R = Brief Visual Memory Test Revised; RCFT = Rey Complex Figure Test; SDMT = Symbol Digit Modalities Test; TMT = Trail Making Test (Part A and B); TAP = Test for Attentional Performance; D-KEFS=Delis-Kaplan Executive Functions System
