‘Is MDMA a Human Neurotoxin?’:Diverse Views from the Discussants

Neuropsychobiology 2000 John Turner, A. C. Parrott 27 citations

UNLABELLED: Every discussant at the Novartis symposium was invited to submit a 250-word abstract, giving their views upon the question: 'Is MDMA a human neurotoxin?'. These abstracts are presented here. They illustrate a wide range of viewpoints and opinions, as might be expected from experts in such diverse fields: animal neuroscience, human cognitive testing, police pathology laboratory,...

Deconstructing Ecstasy: The Politics Of Mdma Research

Addiction Research & Theory 2000 Charles S. Grob 79 citations

What is Ecstasy? Defined by the New Webster's Dictionary as a state of intense overpowering emotion, a condition of exultation or mental rapture induced by beauty, music, artistic creation or the contemplation of the divine, ecstasy derives etymologically from the ancient Greek ekstasis, which means flight of the soul from the body. The anthropologist, Mircea Eliade, who explored the roots of...

(±)3,4-Methylenedioxymethamphetamine (‘Ecstasy’)-Induced Serotonin Neurotoxicity: Clinical Studies

Neuropsychobiology 2000 Una D. Mccann, Victoria Eligulashvili, George A. Ricaurte 192 citations

(±)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...

Potential Human Neurotoxicity of MDMA (‘Ecstasy’): Subjective Self-Reports, Evidence from an Italian Drug Addiction Centre and Clinical Case Studies

Neuropsychobiology 2000 Fabrizio Schifano 83 citations

The present paper attempts to give an updated overview of the magnitude of the phenomenon of ecstasy abuse in Italy and other European countries. It gives an account of some clinical case studies and of a larger-scale report on polydrug (including MDMA) consumers attending our Public Health Addiction Treatment Unit in recent years, with a view to clarifying the characteristics and...

(±)3,4-Methylenedioxymethamphetamine (‘Ecstasy’)-Induced Serotonin Neurotoxicity: Studies in Animals

Neuropsychobiology 2000 George A. Ricaurte, Jie Yuan, Una D. Mccann 291 citations

The popular recreational drug, (±)3,4-methylenedioxymethamphetamine (MDMA; ‘Ecstasy’) is a potent and selective brain serotonin (5-HT) neurotoxin in animals. MDMA-induced 5-HT neurotoxicity can be demonstrated using a variety of neurochemical, neuroanatomical and, more recently, functional measures of 5-HT neurons. Although the neurotoxic effects of MDMA in animals are widely accepted, the...

A three-choice discrimination procedure dissociates the discriminative stimulus effects of d-amphetamine and (±)-MDMA in rats.

Experimental and Clinical Psychopharmacology 2000 A. K. Goodwin, L. E. Baker 44 citations

(+/-)-3,4-Methylenedioxymethamphetamine (MDMA) produces subjective effects in humans that are similar to, but distinguishable from, those of psychostimulants. Drug discrimination studies in nonhumans have yielded inconsistent results regarding the similarities between MDMA and the psychomotor stimulant d-amphetamine. This study successfully used a 3-choice operant procedure to establish MDMA...

Human Research on MDMA (3,4-Methylene- dioxymethamphetamine) Neurotoxicity: Cognitive and Behavioural Indices of Change

Neuropsychobiology 2000 A. C. Parrott 153 citations

Laboratory animals can develop serotonergic neurotoxicity after repeated doses of 3,4-methylenedioxymethamphetamine (MDMA) or ‘Ecstasy’. If similar neural damage occurs in humans, this may be evident in cognitive or behavioural impairments. In a review of the behavioural skills shown by drug-free recreational Ecstasy users, three aspects of cognitive performance are often affected: reduced...

Is MDMA (‘Ecstasy’) Neurotoxic in Humans? An Overview of Evidence and of Methodological Problems in Research

Neuropsychobiology 2000 Helen Valerie Curran 143 citations

Evidence from research with a range of animal species, from rodents to non-human primates, has shown that MDMA (±3,4-methylenedioxymethamphetamine) is neurotoxic. This article explores the evidence that MDMA may be neurotoxic in humans by briefly overviewing three types of research: (1) neurobiological, (2) psychological/somatic and (3) psychiatric. The first type of evidence derives from...

Investigation of the prejunctional α2‐adrenoceptor mediated actions of MDMA in rat atrium and vas deferens

British Journal of Pharmacology November 1, 1999 Aisling Lavelle, Valerie Honner, James R. Docherty 55 citations

We have investigated the effects of methylenedioxymethamphetamine (MDMA, ‘ecstasy’) on peripheral noradrenergic neurotransmission in the rat. In rat atrial slices pre‐incubated with [ 3 H]‐noradrenaline and in the presence of desipramine (1 μ M ) to prevent effects of MDMA on basal outflow of tritium, MDMA (10 μ M ) significantly inhibited the release of tritium evoked by short trains of six...

α-Lipoic acid prevents 3,4-methylenedioxy-methamphetamine (MDMA)-induced neurotoxicity

Neuroreport November 1, 1999 Norberto Aguirre, Meritxell Barrionuevo, Marı́a J. Ramı́rez et al. 89 citations

A single administration of 3,4-methylenedioxymetham-phetamine (MDMA, 20 mg/kg, i.p.), induced significant hyperthermia in rats and reduced 5-hydroxytryptamine (5-HT) content and [3H]paroxetine-labeled 5-HT transporter density in the frontal cortex, striatum and hippocampus by 40–60% 1 week later. MDMA treatment also increased glial fibrillary acidic protein (GFAP) immunoreactivity in the...
