Detection of acute 3,4-methylenedioxymethamphetamine (MDMA) effects across protocols using automated natural language processing

Neuropsychopharmacology January 24, 2020 Carla Agurto, Guillermo Cecchi, Raquel Norel et al. 33 citations

Abstract The detection of changes in mental states such as those caused by psychoactive drugs relies on clinical assessments that are inherently subjective. Automated speech analysis may represent a novel method to detect objective markers, which could help improve the characterization of these mental states. In this study, we employed computer-extracted speech features from multiple domains...

Oxytocin receptor gene variation predicts subjective responses to MDMA

Social Neuroscience January 20, 2016 Anya K. Bershad, Jessica Weafer, Matthew G. Kirkpatrick et al. 35 citations

3,4-Methylenedioxymethamphetamine (MDMA, "ecstasy") enhances desire to socialize and feelings of empathy, which are thought to be related to increased oxytocin levels. Thus, variation in the oxytocin receptor gene (OXTR) may influence responses to the drug. Here, we examined the influence of a single OXTR nucleotide polymorphism (SNP) on responses to MDMA in humans. Based on findings that...

MDMA alters emotional processing and facilitates positive social interaction

Psychopharmacology April 12, 2014 Margaret C. Wardle, Harriet de Wit 97 citations

±3,4-Methylenedioxymethamphetamine (MDMA, “ecstasy”) produces “prosocial” effects, such as feelings of empathy and closeness, thought to be important to its abuse and its value in psychotherapy. However, it is not fully understood how MDMA alters basic emotional processes to produce these effects, or whether it produces corresponding changes in actual social behavior. Here, we examined how MDMA...

‘Ecstasy’ as a social drug: MDMA preferentially affects responses to emotional stimuli with social content

Social Cognitive and Affective Neuroscience March 27, 2014 Margaret C. Wardle, Matthew G. Kirkpatrick, Harriet de Wit 52 citations

3,4-Methylenedioxymethamphetamine (MDMA, 'ecstasy') is used recreationally to improve mood and sociability, and has generated clinical interest as a possible adjunct to psychotherapy. One way that MDMA may produce positive 'prosocial' effects is by changing responses to emotional stimuli, especially stimuli with social content. Here, we examined for the first time how MDMA affects subjective...
