Seven hours after 39 migraineurs and 37 controls consumed an amino acid drink that contained or omitted l-tryptophan (thereby reducing brain serotonin synthesis), motion sickness was provoked by the visual illusion of movement. Tryptophan depletion boosted dizziness, nausea, and the illusion of movement in controls to levels that approached those of migraineurs. Thus, reduced brain serotonin activity may promote vestibuloocular disturbances during motion sickness and attacks of migraine.
