Zakzanis A1 Donald A. Young YR 2001 UL http://n.neurology.org/content/56/7/966.abstract AB To examine the neurotoxic potential of continued MDMA (“Ecstasy”) use in humans and its functional consequences over the course of 1 year, 15 MDMA users participated in a longitudinal study in which they completed a brief neuropsychological test battery composed mainly of retrospective and prospective memory tasks. Subjects were abstinent for 2 weeks on initial and 1-year testing. Continued use of MDMA was associated with progressive decline in terms of immediate and delayed recall.
