Abstract
Since the late 1980s the psychoactive drug 3,4-methylenedioxymethamphetamine (MDMA) has had a well-known history as the recreationally used drug ecstasy. What is less well known by the public is that MDMA started its life as a therapeutic agent and that in recent years an increasing amount of clinical research has been undertaken to revisit the drug's medical potential. MDMA has unique pharmacological properties that translate well to its proposed agent to assist trauma-focused psychotherapy. Psychological trauma-especially that which arises early in life from child abuse-underpins many chronic adult mental disorders, including addictions. Several studies of recent years have investigated the potential role of MDMA-assisted psychotherapy as a treatment for post-traumatic stress disorder, with ongoing plans to see MDMA therapy licensed and approved within the next 5 years. Issues of safety and controversy frequently surround this research, owing to MDMA's often negative media-driven bias. However, accurate examination of the relative risks and benefits of clinical MDMA-in contrast to the recreational use of ecstasy-must be considered when assessing its potential benefits and the merits of future research. In this review, the author describes these potential benefits and explores the relatives risks of MDMA-assisted psychotherapy in the context of his experience as a child and adolescent psychiatrist, having seen the relative limitations of current pharmacotherapies and psychotherapies for treating complex post-traumatic stress disorder arising from child abuse.Entities:

Relating 3,4-methylenedioxymethamphetamine’s (MDMA) psychotherapeutic effects to its unique receptor profile [8]
| Receptors or brain region involved | MDMA effects | How effects relate to treatment of PTSD | Neurobiological correlates | |
|---|---|---|---|---|
| Serotonin | Reduces depression and anxiety | Provides patient with an experience of positive mood and reduced anxiety in increased engagement | Release of presynaptic 5-hydroxytryptamine (5-HT) at 5-HT1A and 5-HT1B receptors | |
| Stimulates alterations in the perceptions of meaning | Opportunity to see old problems in a new light | Optimum level of arousal | Increased activity at the 5-HT2A receptors | |
| Dopamine and norepinephrine | Raises levels of arousal | Stimulating effect increases motivation to engage in therapy | Release of dopamine and noradrenaline | |
| Alpha-2 adrenoreceptors | Increases relaxation | Reduces hypervigilance associated with PTSD | Increased alpha 2-adrenoceptor activity | |
| Hormonal effects | Improves fear extinction learning | Allows reflection on traumatic memories during psychotherapy without being overwhelmed | Release of noradrenaline and cortisol | |
| Increases emotional attachment and feelings of trust and empathy | Improved relationship between patient and therapist. Capacity to reflect on traumatic memories | Multiple factors, including release of oxytocin | ||
| More likely to use words relating to friendship, and intimacy | Generate discussion about wider aspects of the patient’s social and emotional relationships | |||
| Reduced social exclusion phenomena | Opportunity to reflect upon patients’ wider social functioning | |||
| Regional brain changes | Improved detection of happy faces and reduced detection of negative faces | Enhances levels of shared empathy and prosocial functioning | Increased PFC activation and decreased amygdala fear response | |
| Reduced subjective fear response on recall of negative memories | Opportunity to reflect upon painful memories of trauma during psychotherapy | Decreased cerebral blood flow in the right amygdala and hippocampus | ||
PTSD = post-traumatic stress disorder; PFC = prefrontal cortex
