MDMA in Adolescent Male Rats

Annals of the New York Academy of Sciences August 1, 2006 Raquel Faria, Ana Magalhães, Pedro Monteiro et al. 29 citations

Abstract: Long‐term behavioral consequences of the neurotoxicity produced by 3,4‐methylenedioxymethamphetamine (MDMA) in the adolescent rat are still mostly unknown. Here, adolescent male rats (postnatal day 45 PND [45]) were exposed to 10 mg/kg of MDMA, intraperitoneally, every 2 h for 6 h. Controls were given 0.9% saline in the same protocol. Ten days after exposure, the behavioral effects of...

Cannabidiol, a Cannabis sativa constituent, as an antipsychotic drug

Brazilian Journal of Medical and Biological Research April 1, 2006 Antônio Waldo Zuardi, José A. Crippa, Jaime E. C. Hallak et al. 411 citations

A high dose of delta9-tetrahydrocannabinol, the main Cannabis sativa (cannabis) component, induces anxiety and psychotic-like symptoms in healthy volunteers. These effects of delta9-tetrahydrocannabinol are significantly reduced by cannabidiol (CBD), a cannabis constituent which is devoid of the typical effects of the plant. This observation led us to suspect that CBD could have anxiolytic...

Problematic versus non-problematic ecstasy/MDMA use: the influence of drug usage patterns and pre-existing psychiatric factors

Journal of Psychopharmacology March 30, 2006 Kirstie Soar, John Turner, A. C. Parrott 65 citations

Recreational ecstasy (3,4-methylenedioxymethamphetamine; MDMA) use has been increasingly associated with a number of psychiatric symptoms and psychological problems. However, previous studies assessing possible psychopathological effects have not identified whether users consider their ecstasy use ‘problematic’ or not. In addition, research has generally failed to address the potential role of...

A review of the acute subjective effects of MDMA/ecstasy

Addiction March 24, 2006 Chelsea A. Baylen, Harold Rosenberg 214 citations

ABSTRACT Aim Although several relatively recent reviews have summarized the neuropsychiatric effects associated with chronic ecstasy use, there is no published comprehensive review of studies on the acute subjective effects (ASEs) of MDMA/ecstasy. Design The present study reviewed the prevalence, intensity and duration of ASEs collected from 24 studies that provided frequency data on the...

'The ghost pushes you down': sleep paralysis-type panic attacks in a Khmer refugee population.

Transcultural Psychiatry March 1, 2005 Devon E Hinton, Vuth Pich, Dara Chhean et al.

Among a psychiatric population of Cambodian refugees (N = 100), 42% had current--i.e. at least once in the last year--sleep paralysis (SP). Of those experiencing SP, 91% (38/42) had visual hallucinations of an approaching being, and 100% (42/42) had panic attacks. Among patients with post-traumatic stress disorder (PTSD; n = 45), 67% (30/45) had SP, whereas among those without PTSD, only 22.4%...

Among Cambodian refugees attending a psychiatric clinic (n=100), 49% (49/100) had at least one episode of sleep paralysis (SP) in the previous 12 months. The annual and monthly SP prevalences were much higher in posttraumatic stress disorder (PTSD) than in non-PTSD patients. Among the PTSD patients, 65% (30/46) had monthly episodes of SP versus 14.85% (8/54) among non-PTSD patients (chi2[2,...

Endocannabinoids and exercise.

British journal of sports medicine October 1, 2004 A Dietrich, W F McDaniel

Exercise induces changes in mental status, particularly analgesia, sedation, anxiolysis, and a sense of wellbeing. The mechanisms underlying these changes remain unknown. Recent findings show that exercise increases serum concentrations of endocannabinoids, suggesting a possible explanation for a number of these changes. This article provides an overview of this emerging field.
