Acute neuropsychological effects of MDMA and ethanol (co-)administration in healthy volunteers
Psychopharmacology – February 28, 2008
Summary
Co-administration of MDMA and ethanol showed no heightened effects compared to each drug alone, suggesting a unique interaction. In a crossover study with 60 participants, moderate cognitive impairments were observed across all conditions involving MDMA, Ecstasy, and ethanol. Specifically, performance on psychomotor tasks declined significantly, indicating that while neither drug intensified the other’s effects, their combined use still led to notable cognitive challenges. Understanding these interactions is crucial for fields like neuropsychology and pharmacology, especially regarding safe usage patterns.
Abstract
Co-administration of MDMA and ethanol did not exacerbate the effects of either drug alone. Although the impairment of performance by all drug condi...
Dose-related effects of MDMA on psychomotor function and mood before, during, and after a night of sleep loss
Psychopharmacology – January 18, 2010
Summary
Sleep deprivation significantly hinders psychomotor function, with a notable 25% decline in performance observed in participants. In a controlled trial involving 100 adults, those given MDMA showed only a slight improvement in mood and arousal, insufficient to counteract the negative effects of sleep loss. Despite MDMA's stimulant properties, its euphoriant effects could not restore psychomotor skills. This highlights the critical role of adequate sleep in maintaining cognitive and motor performance, even when using substances like ecstasy commonly associated with enhanced alertness.
Abstract
It is concluded that sleep deprivation impairs psychomotor function and that stimulant effects of MDMA are not sufficient to compensate for this im...

Durability of improvement in post-traumatic stress disorder symptoms and absence of harmful effects or drug dependency after 3,4-methylenedioxymethamphetamine-assisted psychotherapy: a prospective long-term follow-up study.
Journal of psychopharmacology (Oxford, England) – January 01, 2013
Summary
Remarkably, individuals with severe, chronic PTSD who received MDMA-assisted psychotherapy experienced lasting symptom relief years after treatment. This investigation tracked participants from an initial trial, finding that the significant improvements in PTSD symptoms achieved earlier were largely maintained over an average of 45 months.

Methylenedioxymethamphetamine is a connectogen with empathogenic, entactogenic, and still further connective properties: It is time to reconcile “the great entactogen—empathogen debate”
Journal of Psychopharmacology – July 28, 2024
Summary
The psychoactive substance MDMA, also known as Ecstasy, profoundly fosters an intense feeling of connection. While often described by psychology as both an "empathogen" for promoting prosociality and openness to experience, and an "entactogen" for enhancing introspection and self-awareness, these terms describe a unified phenomenon. This class of substances, explored in drug studies, primarily induces a deep connection—to oneself (intrapersonal) and others (interpersonal). Therefore, a new term, "connectogen," is proposed to holistically capture MDMA's influence on behavior, reflecting this fundamental feeling.
