Methylenedioxymethamphetamine (MDMA; "Ecstasy") is a popular recreational drug and brain serotonin (5-HT) neurotoxin. Neuroimaging data indicate that some human MDMA users develop persistent deficits in brain 5-HT neuronal markers. Although the consequences of MDMA-induced 5-HT neurotoxicity are not fully understood, abstinent MDMA users have been found to have subtle cognitive deficits and alt...

(+/-)3,4-Methylenedioxymethamphetamine (MDMA, 'Ecstasy') is a brain serotonergic neurotoxin in experimental animals, including nonhuman primates. It is also an increasingly popular recreational drug of abuse, and doses of MDMA that are used recreationally overlap with those that produce serotonin (5-HT) neurotoxicity in animals. Studies in human MDMA users probing for evidence of brain serotone...

Ecstasy normally contains 3,4 methylenedioxymethamphetamine (MDMA) that increases the levels of serotonin, dopamine, and epinephrine in the central nervous system with consequent adverse effects on the cardiovascular system. Herein, we presented a case of ecstasy abuse which resulted in two episodes myocardial infarction during a three month period; the second episode led to death due to thromb...

Background The popular recreational abuse drug 3,4-methylenedioxymethamphetamine (MDMA, 'Ecstasy') produces acute and long-lasting deficits in several markers of the serotonergic (5-HT) system. BDNF (brain derived neurotrophic factor) is a prominent trophic factor of serotonergic fibers. The aim of this study was to characterize the damage of serotonergic fibers in the frontoparietal cortex and...

BACKGROUND 3,4-methylenedioxymethamphetamine (MDMA or "Ecstasy") is known to damage brain serotonin neurons in animals and possibly humans. Because serotonergic damage may adversely affect memory, we compared verbal memory function between MDMA users and MDMA-naïve control subjects and evaluated the relationship between verbal memory function and neuronal dysfunction in the MDMA users. METHOD...

There is evidence that some heavy users of 3,4-methylenedioxymethamphetamine (MDMA, ecstasy) show signs of neurotoxicity (a cognitive dysfunction, a larger incidence of psychopathology). It has been postulated that the catechol intermediates of methylenedioxyamphetamines such as 3,4-dihydroxymethamphetamine (HHMA), a metabolite of MDMA, may play a role in their neurotoxicity by formation of thi...

The amphetamine derivative 3,4-methylenedioxymethamphetamine (MDMA, ecstasy) reverses dopamine and serotonin transporters to produce efflux of dopamine and serotonin, respectively, in regions of the brain that have been implicated in reward. However, the role of serotonin/dopamine interactions in the behavioral effects of MDMA remains unclear. We previously showed that MDMA-induced locomotion, ...

3,4-Methylenedioxymethamphetamine (MDMA) is a psychoactive drug of abuse which is increasingly popular in human recreational drug use. In rats, the drug has been shown to stimulate locomotion while decreasing exploratory behavior. MDMA acts as an indirect agonist of serotonin (5-HT) receptors by inducing 5-HT release by a 5-HT reuptake transporterdependent mechanism, although it is not known wh...

We previously showed that developmental 3,4-methylenedioxymethamphetamine (MDMA) treatment induces long-term spatial and egocentric learning and memory deficits and serotonin (5-HT) reductions. During brain development, 5-HT is a neurotrophic factor influencing neurogenesis, synaptogenesis, migration, and target field organization. MDMA (10 mg/kg × 4/d at 2 h intervals) given on post-natal day ...
