Individual participant data systematic review and meta-analysis of randomised controlled trials assessing adult mindfulness-based programmes for mental health promotion in non-clinical settings.

Nature. Mental health July 10, 2023 Julieta Galante, Claire Friedrich, Napaporn Aeamla-Or et al. 102 citations

Mindfulness-based programmes (MBPs) are widely used to prevent mental ill-health that is becoming the leading global cause of morbidity. Evidence suggests beneficial average effects but wide variability. We aimed to confirm the effect of MBPs on psychological distress, and to understand whether and how baseline distress, gender, age, education, and dispositional mindfulness modify the effect of...

Acute effects of MDMA (3,4-methylenedioxymethamphetamine) on EEG oscillations: alone and in combination with ethanol or THC (delta-9-tetrahydrocannabinol).

Psychopharmacology February 2011 Marieke M Lansbergen, Glenn J H Dumont, Joop M A Van Gerven et al.

Typical users of 3,4-methylenedioxymethamphetamine (MDMA or "ecstasy") are polydrug users, combining MDMA with alcohol or cannabis [most active compound: delta-9-tetrahydrocannabinol (THC)]. The aim of the present study was to investigate whether co-administration of alcohol or THC with MDMA differentially affects ongoing electroencephalogram (EEG) oscillations compared to the administration of...

Increased oxytocin concentrations and prosocial feelings in humans after ecstasy (3,4-methylenedioxymethamphetamine) administration

Social Neuroscience June 25, 2009 Glenn Dumont, Fred C.g.j. Sweep, R. van der Steen et al. 238 citations

MDMA (3,4-methylenedioxymethamphetamine or "ecstasy") is a recreationally used drug with remarkable and characteristic prosocial effects. In spite of abundant attention in the scientific literature, the mechanism of its prosocial effects has not been elucidated in humans. Recently, research in animals has suggested that the neuropeptide oxytocin may induce these effects. In a double blind,...

Psychotic symptoms in narcolepsy: phenomenology and a comparison with schizophrenia.

General Hospital Psychiatry 2009 Hal A Droogleever Fortuyn, G A Lappenschaar, Fokko J Nienhuis et al.

Patients with narcolepsy often experience pervasive hypnagogic hallucinations, sometimes even leading to confusion with schizophrenia. We aimed to provide a detailed qualitative description of hypnagogic hallucinations and other "psychotic" symptoms in patients with narcolepsy and contrast these with schizophrenia patients and healthy controls. We also compared the prevalence of formal...

Acute neuropsychological effects of MDMA and ethanol (co-)administration in healthy volunteers

Psychopharmacology February 28, 2008 Glenn Dumont, E. Wezenberg, M. M. G. J. Valkenberg et al. 50 citations

Co-administration of MDMA and ethanol did not exacerbate the effects of either drug alone. Although the impairment of performance by all drug conditions was relatively moderate, all induced significant impairment of cognitive function.
