Summary
This study aims to investigate synaptic physiology and behavioral inhibition in patients with NF1 and ASD and to answer whether inhibitory deficits at these levels are modulated by lovastatin. Structure: (1) Visit 1: Baseline assessment- participant's characterization, baseline outcome measures and additional evaluations, (2) 3 consecutive days of physiologically probing drug/placebo intake, (3) Visit 2: Outcome measures and additional evaluations in the day after the last drug/placebo intake, (4) Washout period of 4 to 6 weeks, (5) 3 consecutive days of drug/placebo intake, (6) Visit 3: Outcome measures and additional evaluations in the day after the last placebo/drug intake.
