3,4-Methylenedioxymethamphetamine (MDMA) is widely used recreationally but also modulates serotonergic signaling in the gut, potentially influencing the microbiota. Because low bone mineral density (BMD) is common in depression and other psychiatric disorders, we tested whether repeated, intermittent MDMA attenuates BMD loss in ovariectomized (OVX) mice. OVX mice received MDMA (10 mg/kg) three...
3,4-methylenedioxymethamphetamine (MDMA) is an amphetamine derivative known as an "entactogen," influencing emotional and social processing. Phase III clinical trials of MDMA-assisted psychotherapy for post-traumatic stress disorder have reported promising results, and MDMA-assisted therapy is currently under regulatory review. However, the precise mechanisms underlying positive treatment...
BACKGROUND: Major depressive disorder (MDD) is a leading cause of global disability, and current treatments often fail to provide sustained effectiveness. MDMA-assisted therapy (MDMA-AT) is a promising treatment for MDD. However, the long-term effects are not known. OBJECTIVES: To examine the long-term effects of MDMA-AT for MDD. METHODS: Twelve participants with MDD and an ongoing moderate to...
3,4-Methylenedioxymethamphetamine (MDMA), commonly known as ecstasy, is a psychostimulant with entactogenic properties and known to induce arousal and euphoria. As an amphetamine derivate, MDMA acts on the monoamine systems in the brain and stimulates release of dopamine (DA), noradrenaline (NA) and serotonin (5-HT), yet their individual contributions in driving arousal and euphoria remain...
Little is known about whether 3,4-methylenedioxy-N-methamphetamine (MDMA) neurocognitive side effects improve with sustained abstinence. This study aimed to systematically review and synthesise the existing literature on the long-term neurocognitive side effects of recreational MDMA use after a minimum of 6 months of abstinence. We searched relevant databases utilising terms related to (1) MDMA...
Ecstasy tablets are commonly associated with 3,4-methylenedioxy-methamphetamine (MDMA), but they often contain diverse psychoactive substances, including new psychoactive substances (NPS), which pose significant risks to users due to unknown composition and effects. This study analyzed 150 Ecstasy tablets seized in Poland between 2020 and 2021, shaped as "Stormtrooper" heads, to identify their...
Highly stressful events can lead to post-traumatic stress disorder (PTSD)-a significant public health concern which existing treatments (e.g., psychotherapy and traditional medications) have shown marginal efficacy for.Psychedelics-alternatively called hallucinogens-are psychoactive substances that cause perception, mood, and cognitive changes.Because they are known for their impact on neuron...
Introdução: Uma parcela substancial de pacientes com Transtorno de Estresse Pós-Traumático (TEPT), estimada entre 30% e 50%, não alcança remissão com as terapias padrão-ouro (ISRS e psicoterapia). Este cenário de refratariedade constitui um desafio clínico significativo. A terapia assistida por 3,4-metilenodioximetanfetamina (MDMA) emerge como uma intervenção com potencial disruptivo para esta...

O Transtorno de Estresse Pós-Traumático (TEPT) é uma condição mental que pode surgir após experiências traumáticas, afetando a qualidade de vida dos indivíduos. O tratamento convencional envolve psicoterapia e farmacoterapia, contudo, nem sempre apresenta resultados satisfatórios. Nesse cenário, a psicoterapia assistida por 3,4-metilenodioximetanfetamina (MDMA) tem emergido como alternativa...
Serotonergic psychedelics and 3,4-methylendioxtmethamphetamine (MDMA) are promising treatments for mental disorders with a continuously evolving evidence base. We searched Pubmed/Scopus/clinical trial registries up to 08july2025 for double-blind randomized controlled trials (RCTs) testing MDMA or serotonergic psychedelics in patients with mental disorders. Primary outcomes were change in...
