Syllogistic reasoning performance in MDMA (Ecstasy) users.
Previous research has demonstrated working memory and executive deficits in recreational users of MDMA (3,4-methylenedioxymethamphetamine; Ecstasy). In turn, both of these constructs have been implicated in syllogistic reasoning performance. Twenty-two MDMA users (mean age = 21.36) and 26 MDMA nonuser controls (mean age = 21.31) were tested on syllogisms of varying difficulty and on measures of...
متن کاملExecutive function in abstinent MDMA ('ecstasy') users.
BACKGROUND Methylenedioxymethamphetamine (MDMA, or 'Ecstasy') is a growingly popular recreational drug of abuse that is known to damage brain serotonergic neurons in animals and possibly humans. Few functional consequences of MDMA-induced serotonin neurotoxicity have been identified, either in animals or humans.

Sixty subjects, comprising 20 current light users, 20 ex-users, and 20 non-users of ecstasy, were tested on an extensive battery of cognitive tests. Current light use...
متن کاملBrain serotonin transporter binding in former users of MDMA ('ecstasy').
BACKGROUND Animal experimental studies have prompted concerns that widespread use of 3,4-methylenedioxymethamphetamine (MDMA; 'ecstasy') by young people may pose a major public health problem in terms of persistent serotonin neurotoxicity. AIMS To determine the status of brain serotonin neurons in a group of abstinent MDMA users. METHOD We assessed the integrity of brain serotonin neurons b...
متن کاملMapping serotonergic dysfunction in MDMA (ecstasy) users using pharmacological MRI
3,4-Methylenedioxymethamphetamine (MDMA or ecstasy) is a popular recreational drug that has been shown to induce loss of brain serotonin (5-HT) neurons. The purpose of this study was to determine the usefulness of pharmacological magnetic resonance imaging (phMRI) in assessing 5-HT dysfunction by examining the hemodynamic response evoked by infusion with the selective 5-HT reuptake inhibitor ci...
