Methylenedioxymethamphetamine (MDMA) is generally described as non-addictive. However, this report describes three cases in which criteria for dependence were met. A wider understanding that MDMA can be addictive in rare cases is important as very heavy use may cause lasting neuronal changes. This risk could be reduced with effective identification and treatment of dependent persons. In one cas...

Background: Ecstasy or 3-4, methylenedioxymethamphetamine (MDMA), as an amphetamine derivate, could lead to learning and memory impairment. Objectives: As the hippocampus is responsible for learning and memory, herein we evaluated acute and chronic effects of MDMA on the structure of the hippocampus. Materials and Methods: Male Wistar rats (200-250 g) received single or multiple injections of M...

INTRODUCTION Exposure to 3-4, methylenedioxymethamphetamine (MDMA) leads to cell death. Herein, we studied the protective effects of ginger on MDMA- induced apoptosis. METHODS 15 Sprague dawley male rats were administrated with 0, 10 mg/kg MDMA, or MDMA along with 100mg/kg ginger, IP for 7 days. Brains were removed to study the caspase 3, 8, and 9 expressions in the hippocampus by RT-PCR. Dat...

Use of 3,4-methylenedioxymethamphetamine (MDMA; ecstasy) has increased dramatically in recent years, yet little is known about its effects on the developing brain. Neonatal rats were administered MDMA on days 1-10 or 11-20 (analogous to early and late human third trimester brain development). MDMA exposure had no effect on survival but did affect body weight gain during treatment. After treatme...

3,4-Methylenedioxymethamphetamine (MDMA, "Ecstasy") releases serotonin and dopamine. The role for dopamine in mediating the effects of MDMA has not yet been examined in humans. We investigated the effect of pretreatment with the dopamine D(2) antagonist haloperidol (1.4 mg i.v.) on psychological and physiological responses to MDMA (1.5 mg/kg p.o.) in 14 healthy volunteers using a double-blind p...

The use of the street drug methylenedioxymethamphetamine (MDMA), commonly referred to as ecstasy, has become increasingly prevalent amongst teenagers and young adults in the United States and many other parts of the world. While most anesthesiologists are facile with the intricacies of managing patients intoxicated by alcohol, cocaine and narcotics the new "club" drugs present a challenge, espe...

A recent traffic fatality has been attributed to the use of the drug methylenedioxymethamphetamine (MDMA). The deceased was a 29-year-old white male with no known history of drug abuse. Toxicological analysis detected MDMA and metabolite methylenedioxyamphetamine (MDA) in the blood, urine, and vitreous humor specimens submitted for analysis. The concentrations of MDMA in clotted blood, sodium f...

MDMA (3,4-methylenedioxymethamphetamine or "ecstasy") is a recreationally used drug with remarkable and characteristic prosocial effects. In spite of abundant attention in the scientific literature, the mechanism of its prosocial effects has not been elucidated in humans. Recently, research in animals has suggested that the neuropeptide oxytocin may induce these effects. In a double blind, rand...

Cognitive task performance was assessed in three groups of young people: 10 regular users of 3,4-methylenedioxymethamphetamine (MDMA) who had taken 'ecstasy' 10 times or more; 10 novice MDMA users who had taken 'ecstasy' one to nine times; and 10 control subjects who had never taken MDMA. A computerized battery of cognitive tasks (Cognitive Drug Research system) was undertaken on a day when sub...

The abuse of methylenedioxymethamphetamine (MDMA) during pregnancy is of concern. MDMA treatment of rats during a period of brain growth analogous to late human gestation leads to neurochemical and behavioral changes. MDMA from postnatal day (P)11-20 in rats produces reductions in serotonin and deficits in spatial and route-based navigation. In this experiment we examined the impact of MDMA fro...
