A comparison of MDMA-assisted psychotherapy to non-assisted psychotherapy in treatment-resistant PTSD: A systematic review and meta-analysis

February 6, 2022 / Anxiety Disorders / PTSD, MDMA, Papers / Leave a Comment / By / , , , , , ,

Abstract

Rationale: Novel, evidence-based treatments are required for treatment-resistant post-traumatic stress disorder (PTSD). 3,4-Methylenedioxymethamphetamine (MDMA) has beneficially augmented psychotherapy in several small clinical trials.

Objective: To review the use of MDMA-assisted psychotherapy in treatment-resistant PTSD.

Methods: Systematic searches of four databases were conducted from inception to February 2020. A meta-analysis was performed on trials which were double-blinded, randomised, and compared MDMA-assisted psychotherapy to psychotherapy and placebo. The primary outcomes were the differences in Clinician Administered PTSD Scale (CAPS-IV) score and Beck’s Depression Inventory (BDI). Secondary outcome measures included neurocognitive and physical adverse effects, at the time, and within 7 days of intervention.

Results: Four randomised controlled trials (RCTs) met inclusion criteria. When compared to active placebo, intervention groups taking 75 mg (MD -46.90; 95% (confidence intervals) CI -58.78, -35.02), 125 mg (MD -20.98; 95% CI -34.35, -7.61) but not 100 mg (MD -12.90; 95% CI -36.09, 10.29) of MDMA with psychotherapy, had significant decreases in CAPS-IV scores, as did the inactive placebo arm (MD -33.20; 95% CI -40.53, -25.87). A significant decrease in BDI when compared to active placebo (MD -10.80; 95% CI -20.39, -1.21) was only observed at 75 mg. Compared to placebo, participants reported significantly more episodes of low mood, nausea and jaw-clenching during sessions and lack of appetite after 7 days.

Conclusion: These results demonstrate potential therapeutic benefit with minimal physical and neurocognitive risk for the use of MDMA-assisted psychotherapy in TR-PTSD, despite little effect on Beck’s Depression Inventory. Better powered RCTs are required to investigate further.

Historic psychedelic drug trials and the treatment of anxiety disorders

December 6, 2021 / Anxiety Disorders / PTSD, Papers, Psychiatry & Medicine, Psychology, Publications / By / , , , , , ,

Abstract

Introduction: In this paper, we systematically review literature from 1940 to 2000 relating to the combined use of psychological therapies and psychedelic drugs in the treatment of ICD-10 anxiety disorders.

Methods: The databases Ovid MEDLINE(R), PsycINFO, and Multidisciplinary Association for Psychedelic Studies (MAPS) were searched for case reports and trials involving humans in the treatment of ICD-10 anxiety and related disorders. Twenty-four studies are described; four describe anxiety symptoms in diverse patient groups, 14 studies describe historic diagnoses that usefully correspond with ICD-10 anxiety disorders, six studies pooled results or failed to detail results specific to contemporary ICD-10 anxiety disorders. Two of the 24 studies reported are individual case reports while two of them were inadequate in terms of the reporting of outcome measures. Thus 20 studies were ultimately included in the summary analysis.

Results: Three of the 20 studies reviewed described improvements in anxiety by standardized measures (p < .05) and two studies found that this effect was dose related. Of the 20 studies included in the final analysis, 94 of 145 (65%) cases of “psychoneurotic anxiety reaction” as defined by Diagnostic and Statistical Manual of Mental Disorders-I showed improvement that ranged from moderate improvement to full recovery. Despite methodological inadequacies, the results from previous studies are encouraging and should be used to guide and inform further investigation.

Conclusion: The majority of studies indicate that a combination of psychedelic drug administration and psychological therapy was most beneficial. We found no study suggesting that the pharmacological action of psychedelic drugs in isolation is sufficient.

Psychedelics in the treatment of unipolar mood disorders: A systematic review

October 1, 2016 / Depressive Disorders, LSD, Mushrooms / Psilocybin, Papers, Psychology, Publications / By / , , , ,

Abstract

Unipolar mood disorders, including major depressive disorder and persistent depressive disorder (dysthymia), confer high rates of disability and mortality and a very high socioeconomic burden. Current treatment is suboptimal in most cases and there is little of note in the pharmaceutical development pipeline. The psychedelic drugs, including lysergic acid diethylamide and psilocybin, were used extensively in the treatment of mood disorders, and other psychiatric conditions, before their prohibition in the late 1960s. They are relatively safe when used in medically controlled environments, with no reported risk of dependence. Here, we present a systematic review of published clinical treatment studies using psychedelics in patients with broadly defined unipolar mood disorder, and consider their place in psychiatry. Whilst all the included studies have methodological shortcomings, of 423 individuals in 19 studies, 335 (79.2%) showed clinician-judged improvement after treatment with psychedelics. A recently completed pilot study in the UK favours the use of psilocybin with psychological support in treatment resistant depressive disorder. The evidence overall strongly suggests that psychedelics should be re-examined in modern clinical trials for their use in unipolar mood disorders and other non-psychotic mental health conditions.
