Characteristics of NF1 patients. M = male; F = female; MMSE = mini–mental state examination; IQ = intelligence quotient (mean = 100, SD = 15), measured with the German version of Wechsler Adult Intelligence Scale (WAIS-III). TOVA = Test of Variables of Attention, RTV = response time variability, RT = response time (mean = 100, SD = 15); WURS-k = Wender Utah rating scale, short-version for the assessment of the attention-deficit hyperactivity disorder in childhood (cut-off ≥ 30); ADHS-SB = ADHD Self Rating Scale (cut-off ≥ 15); HADS = Hospital Anxiety and Depression Scale (cut-off ≥ 8).
