Help pay for MDMA PTSD research

December 6, 2021 / Anxiety disorders / PTSD, Articles, MDMA, Publications, Research / By

Recently, MAPS officially launched an Indiegogo campaign to help complete their crucial study of MDMA-assisted psychotherapy for people suffering from post-traumatic stress disorder (PTSD). OPEN supports MAPS in their efforts to raise both funds and awareness. Money is needed to progress vital research on these substances, while increasing awareness on the human and economic costs of PTSD can show that viable alternatives exist that can transform the lives of PTSD-sufferers.

The first published studies have shown that MDMA-assisted psychotherapy can be an effective treatment for people who did not respond to conventional therapies for post-traumatic stress disorder. MAPS’ studies are supported by the US government; their ongoing study in military veterans, firefighters, and police officers is halfway complete, and early results are promising. For some recent articles on MDMA-assisted PTSD-treatment, see here, here and here.

Donations will help pay the costs of conducting our ongoing clinical trial, a critical part of our international research program to develop MDMA-assisted psychotherapy into a prescription treatment for PTSD. Visit the Indiegogo page here,

Pharmacological enhancement of exposure-based treatment in PTSD: a qualitative review

October 17, 2013 / Anxiety disorders / PTSD, MDMA, Papers, Psychiatry, Psychology, Psychopharmacology, Publications / By / , ,

Abstract

There is a good amount of evidence that exposure therapy is an effective treatment for posttraumatic stress disorder (PTSD). Notwithstanding its efficacy, there is room for improvement, since a large proportion of patients does not benefit from treatment. Recently, an interesting new direction in the improvement of exposure therapy efficacy for PTSD emerged. Basic research found evidence of the pharmacological enhancement of the underlying learning and memory processes of exposure therapy. The current review aims to give an overview of clinical studies on pharmacological enhancement of exposure-based treatment for PTSD. The working mechanisms, efficacy studies in PTSD patients, and clinical utility of four different pharmacological enhancers will be discussed: d-cycloserine, MDMA, hydrocortisone, and propranolol.

MDMA enhances emotional empathy and prosocial behavior

October 4, 2013 / Anxiety disorders / PTSD, MDMA, Neuroscience, Papers, Psychology, Publications / By / , , , , , ,

Abstract

3,4-Methylenedioxymethamphetamine (MDMA, ‘ecstasy’) releases serotonin and norepinephrine. MDMA is reported to produce empathogenic and prosocial feelings. It is unknown whether MDMA in fact alters empathic concern and prosocial behavior. We investigated the acute effects of MDMA using the Multifaceted Empathy Test (MET), dynamic Face Emotion Recognition Task (FERT) and Social Value Orientation (SVO) test. We also assessed effects of MDMA on plasma levels of hormones involved in social behavior using a placebo-controlled, double-blind, random-order, cross-over design in 32 healthy volunteers (16 women). MDMA enhanced explicit and implicit emotional empathy in the MET and increased prosocial behavior in the SVO test in men. MDMA did not alter cognitive empathy in the MET but impaired the identification of negative emotions, including fearful, angry and sad faces, in the FERT, particularly in women. MDMA increased plasma levels of cortisol and prolactin, which are markers of serotonergic and noradrenergic activity, and of oxytocin, which has been associated with prosocial behavior. In summary, MDMA sex-specifically altered the recognition of emotions, emotional empathy and prosociality. These effects likely enhance sociability when MDMA is used recreationally and may be useful when MDMA is administered in conjunction with psychotherapy in patients with social dysfunction or post-traumatic stress disorder.

Self-Medication of LSD and MDMA to Treat Mental Disorders: A Case Series

September 18, 2013 / Anxiety disorders / PTSD, Depression, LSD, MDMA, Other subjects, Papers, Psychiatry, Psychology, Publications / By /

Abstract

50 years ago LSD was prescribed to treat a variety of mental illnesses. More recently LSD and MDMA (ecstasy) have become widely used outside medicine as both recreational drugs and by some patients as ‘self-medication’. These brief reports gather together five patients’ experiences using psychedelic drugs to treat their mental disorders. They are discussed in relation to the medical profession’s current growing interest in re-visiting psychedelic drugs as therapeutic treatments in psychiatry. The first case describes the successful self-treatment for depression using LSD, followed by a case in which doctors administered LSD in the 1960s and 1970s to successfully treat a case of obsessive-compulsive disorder (OCD) and chronic fatigue syndrome. The third and fourth cases describe the successful self-treatment of OCD using respectively MDMA and then LSD and the final case describes a self-treatment with LSD to manage Anorexia Nervosa. All the participants describing their use of these drugs give a positive report of self-treatment with minimal adverse effects. They also all support a resumption of more research into the therapeutic use of hallucinogens/psychedelic drugs as potential clinical therapies.

Psilocybin Biases Facial Recognition, Goal-Directed Behavior, and Mood State Toward Positive Relative to Negative Emotions Through Different Serotonergic Subreceptors

December 19, 2012 / Anxiety disorders / PTSD, Depression, Mushrooms / Psilocybin, Neuroscience, Other subjects, Papers, Psychiatry, Psychology, Psychopharmacology, Publications / By / , , , , ,

Abstract

Background
Serotonin (5-HT) 1A and 2A receptors have been associated with dysfunctional emotional processing biases in mood disorders. These receptors further predominantly mediate the subjective and behavioral effects of psilocybin and might be important for its recently suggested antidepressive effects. However, the effect of psilocybin on emotional processing biases and the specific contribution of 5-HT2A receptors across different emotional domains is unknown.

Methods
In a randomized, double-blind study, 17 healthy human subjects received on 4 separate days placebo, psilocybin (215 g/kg), the preferential 5-HT2A antagonist ketanserin (50 mg), or psilocybin plus ketanserin. Mood states were assessed by self-report ratings, and behavioral and event-related potential measurements were used to quantify facial emotional recognition and goal-directed behavior toward emotional cues.

Results
Psilocybin enhanced positive mood and attenuated recognition of negative facial expression. Furthermore, psilocybin increased goal-directed behavior toward positive compared with negative cues, facilitated positive but inhibited negative sequential emotional effects, and valence-dependently attenuated the P300 component. Ketanserin alone had no effects but blocked the psilocybin-induced mood enhancement and decreased recognition of negative facial expression.

Conclusions
This study shows that psilocybin shifts the emotional bias across various psychological domains and that activation of 5-HT2A receptors is central in mood regulation and emotional face recognition in healthy subjects. These findings may not only have implications for the pathophysiology of dysfunctional emotional biases but may also provide a framework to delineate the mechanisms underlying psylocybin’s putative antidepressant effects.

Durability of improvement in posttraumatic stress disorder symptoms and absence of harmful effects or drug dependency after 3,4-methylenedioxymethamphetamine-assisted psychotherapy: a prospective long-term follow-up study

November 20, 2012 / Anxiety disorders / PTSD, MDMA, Papers, Psychiatry, Psychology, Psychopharmacology, Psychotherapy, Publications / By / , , , , , ,

Abstract

We report follow-up data evaluating the long-term outcomes for the first completed trial of 3,4-methylenedioxymethamphetamine (MDMA)-assisted psychotherapy for chronic, treatment-resistant post-traumatic stress disorder (PTSD) (Mithoefer et al., 2011). All of the 19 subjects who received MDMA-assisted treatment in the original trial participated in the long-term follow-up (LTFU), with 16 out of 19 completing all of the long-term outcome measures, which were administered from 17 to 74 months after the original study’s final MDMA session (mean = 45.4; SD = 17.3). Our primary outcome measure used was the Clinician-Administered PTSD Scale (CAPS). Secondary outcome measures were the Impact of Events Scale-Revised (IES-R) and the Neuroticism Extroversion Oppenness Personality Inventory-Revised (NEO PI-R) Personality Inventory. We also collected a long-term follow-up questionnaire. Results for the 16 CAPS completers showed there were no statistical differences between mean CAPS score at LTFU (mean = 23.7; SD = 22.8) (t_matched = 0.1; df = 15, p = 0.91) and the mean CAPS score previously obtained at Study Exit (mean = 24.6, SD = 18.6). On average, subjects maintained statistically and clinically-significant gains in symptom relief, although two of these subjects did relapse. It was promising that we found the majority of these subjects with previously severe PTSD who were unresponsive to existing treatments had symptomatic relief provided by MDMA-assisted psychotherapy that persisted over time, with no subjects reporting harm from participation in the study.

A randomized, controlled pilot study of MDMA (± 3,4-Methylenedioxymethamphetamine)-assisted psychotherapy for treatment of resistant, chronic Post-Traumatic Stress Disorder (PTSD)

October 31, 2012 / Anxiety disorders / PTSD, MDMA, Papers, Psychiatry, Psychology, Psychopharmacology, Psychotherapy, Publications / By / , , ,

Abstract

Psychiatrists and psychotherapists in the US (1970s to 1985) and Switzerland (1988-1993) used MDMA legally as a prescription drug, to enhance the effectiveness of psychotherapy. Early reports suggest that it is useful in treating trauma-related disorders. Recently, the first completed pilot study of MDMA-assisted psychotherapy for PTSD yielded encouraging results. Designed to test the safety and efficacy of MDMA-assisted psychotherapy in patients with treatment-resistant PTSD; our randomized, double-blind, active-placebo controlled trial enrolled 12 patients for treatment with either low-dose (25 mg, plus 12.5 mg supplemental dose) or full-dose MDMA (125 mg, plus 62.5 mg supplemental dose). MDMA was administered during three experimental sessions, interspersed with weekly non-drug-based psychotherapy sessions. Outcome measures used were the Clinician-Administered PTSD Scale (CAPS) and the Posttraumatic Diagnostic Scale (PDS). Patients were assessed at baseline, three weeks after the second and third MDMA session (end of treatment), and at the 2-month and 1-year follow-ups. We found that MDMA-assisted psychotherapy can be safely administered in a clinical setting. No drug-related serious adverse events occurred. We did not see statistically significant reductions in CAPS scores (p = 0.066), although there was clinically and statistically significant self-reported (PDS) improvement (p = 0.014). CAPS scores improved further at the 1-year follow-up. In addition, three MDMA sessions were more effective than two (p = 0.016).

The NMDA antagonist ketamine and the 5-HT agonist psilocybin produce dissociable effects on structural encoding of emotional face expressions

July 27, 2012 / Anxiety disorders / PTSD, Depression, Ketamine, Mushrooms / Psilocybin, Neuroscience, Other subjects, Papers, Psychology, Publications / By / , , , ,

Abstract

Rationale
Both glutamate and serotonin (5-HT) play a key role in the pathophysiology of emotional biases. Recent studies indicate that the glutamate N-methyl-D-aspartate (NMDA) receptor antagonist ketamine and the 5-HT receptor agonist psilocybin are implicated in emotion processing. However, as yet, no study has systematically compared their contribution to emotional biases.

Objectives
This study used event-related potentials (ERPs) and signal detection theory to compare the effects of the NMDA (via S-ketamine) and 5-HT (via psilocybin) receptor system on non-conscious or conscious emotional face processing biases.

Methods
S-ketamine or psilocybin was administrated to two groups of healthy subjects in a double-blind within-subject placebo-controlled design. We behaviorally assessed objective thresholds for non-conscious discrimination in all drug conditions. Electrophysiological responses to fearful, happy, and neutral faces were subsequently recorded with the face-specific P100 and N170 ERP.

Results
Both S-ketamine and psilocybin impaired the encoding of fearful faces as expressed by a reduced N170 over parieto-occipital brain regions. In contrast, while S-ketamine also impaired the encoding of happy facial expressions, psilocybin had no effect on the N170 in response to happy faces.

Conclusion
This study demonstrates that the NMDA and 5-HT receptor systems differentially contribute to the structural encoding of emotional face expressions as expressed by the N170. These findings suggest that the assessment of early visual evoked responses might allow detecting pharmacologically induced changes in emotional processing biases and thus provides a framework to study the pathophysiology of dysfunctional emotional biases.

Could MDMA be useful in the treatment of post-traumatic stress disorder?

December 15, 2011 / Anxiety disorders / PTSD, MDMA, Papers, Psychiatry, Psychology, Psychopharmacology, Publications / By /

Abstract

In recent studies, 3,4-methylenedioxymethylamphetamine (MDMA) has shown promise in the treatment of post-traumatic stress disorder (PTSD) as an adjunct to post-trauma psychological therapy. However, because of historical associations with its use as the recreational drug ecstasy, MDMA research remains a controversial subject. Dr Sessa discusses these controversies and describes a UK-based MDMA/PTSD currently in development.

MDMA-Assisted Psychotherapy Using Low Doses in a Small Sample of Women with Chronic Posttraumatic Stress Disorder

September 8, 2011 / Anxiety disorders / PTSD, MDMA, Papers, Psychiatry, Psychology, Psychopharmacology, Psychotherapy, Publications / By / , , , ,

Abstract

The purpose of this study was to investigate the safety of different doses of MDMA-assisted psychotherapy administered in a psychotherapeutic setting to women with chronic PTSD secondary to a sexual assault, and also to obtain preliminary data regarding efficacy. Although this study was originally planned to include 29 subjects, political pressures led to the closing of the study before it could be finished, at which time only six subjects had been treated. Preliminary results from those six subjects are presented here. We found that low doses of MDMA (between 50 and 75 mg) were both psychologically and physiologically safe for all the subjects. Future studies in larger samples and using larger doses are needed in order to further clarify the safety and efficacy of MDMA in the clinical setting in subjects with PTSD.
