This single-center, randomized, double-blind, four-period crossover study will investigate the effect of alcohol on the pharmacodynamics and pharmacokinetics of RO4917838 in healthy volunteers. Healthy volunteers will receive 4 treatments in a randomized order: single dose of RO4917838 and alcohol, RO4917838 and non-alcoholic drink, placebo to RO4917838 and alcohol, and placebo to RO4917838 and non-alcoholic drink.
