The hidden therapist: evidence for a central role of music in psychedelic therapy

February 2, 2018 / Depressive Disorders, Mushrooms / Psilocybin, Papers, Psychology, Publications / By / , , , , ,

Abstract

RATIONALE:
Recent studies have supported the safety and efficacy of psychedelic therapy for mood disorders and addiction. Music is considered an important component in the treatment model, but little empirical research has been done to examine the magnitude and nature of its therapeutic role.
OBJECTIVES:
The present study assessed the influence of music on the acute experience and clinical outcomes of psychedelic therapy.
METHODS:
Semi-structured interviews inquired about the different ways in which music influenced the experience of 19 patients undergoing psychedelic therapy with psilocybin for treatment-resistant depression. Interpretative phenomenological analysis was applied to the interview data to identify salient themes. In addition, ratings were given for each patient for the extent to which they expressed “liking,” “resonance” (the music being experienced as “harmonious” with the emotional state of the listener), and “openness” (acceptance of the music-evoked experience).
RESULTS:
Analyses of the interviews revealed that the music had both “welcome” and “unwelcome” influences on patients’ subjective experiences. Welcome influences included the evocation of personally meaningful and therapeutically useful emotion and mental imagery, a sense of guidance, openness, and the promotion of calm and a sense of safety. Conversely, unwelcome influences included the evocation of unpleasant emotion and imagery, a sense of being misguided and resistance. Correlation analyses showed that patients’ experience of the music was associated with the occurrence of “mystical experiences” and “insightfulness.” Crucially, the nature of the music experience was significantly predictive of reductions in depression 1 week after psilocybin, whereas general drug intensity was not.
CONCLUSIONS:
This study indicates that music plays a central therapeutic function in psychedelic therapy.

A Single Dose Of Ayahuasca Modulates Salivary Cortisol In Treatment-Resistant Depression

January 31, 2018 / Ayahuasca, Depressive Disorders, Neuroscience, Papers, Psychology, Publications / By / , , , , , ,

Abstract

Major depression is a highly prevalent mood disorder, affecting about 350 million people, and around 30% of the patients are resistant to currently available antidepressant medications. Recent evidence from a randomized placebo-controlled trial supports the rapid antidepressant effects of the psychedelic ayahuasca in treatment-resistant depression. The aim of this study was to explore the effect of ayahuasca on plasma cortisol and awakening salivary cortisol response, in the same group of treatment-resistant patients and in healthy volunteers. Subjects received a single dose of ayahuasca or placebo, and both plasma and awakening salivary cortisol response were measured at baseline (before dosing) and 48h after the dosing session. Baseline assessment (D0) showed blunted awakening salivary cortisol response and hypocortisolemia in patients (DM), both with respect to healthy controls group (C). Salivary cortisol also was measured during dosing session and we observed a large increased for both C and DM that ingested ayahuasca, than placebo groups. After 48h of the dosing session (D2) with ayahuasca, awakening salivary cortisol response (for both sexes) of treated patients became similar to levels detected in controls. This was not observed in patients that ingested placebo. No changes in plasma cortisol were observed after 48 hours of ayahuasca or placebo ingestion for both groups and sexes. Therefore, these findings point to new evidence of modulation of ayahuasca on salivary cortisol levels, as cortisol acts in regulation of distinct physiological pathways, emotional and cognitive processes related to etiology of depression, this modulation could be an important part of the antidepressant effects observed with ayahuasca. Moreover, this study highlights the importance of psychedelics in the treatment of human mental disorders.

Acute antidepressant effect of ayahuasca in juvenile non-human primate model of depression

January 25, 2018 / Ayahuasca, Depressive Disorders, Papers, Psychology, Publications / By / , , , , , ,

Abstract

The incidence of major depression in adolescents, aged between 15 to 18 years, reaches approximately 14%. Usually, this disorder presents a recurrent way, without remission of symptoms even after several pharmacological treatments, persisting through adult life. Due to the relatively low efficacy of commercially available antidepressant, new pharmacological therapies are under continuous exploration. Recent evidence suggests that classic psychedelics, such as ayahuasca, produce rapid and robust antidepressant effects in treatment-resistant depression patients. In this study, we evaluated the potential of antidepressant effects of ayahuasca in a juvenile model of depression in a non-human primate, common marmoset (Callithrix jacchus). The model induces depressive-like symptoms by chronic social isolation (60 days) and antidepressant effects monitoring included fecal cortisol, body weight, and behavioral parameters. The animals presented hypocortisolemia and the recovery of cortisol to baseline levels started already at 24h after the ingestion of ayahuasca, but not the vehicle. Moreover, in males, ayahuasca, and not the vehicle, reduced the scratching, a stereotypic behavior, and increased the feeding. Ayahuasca also improving body weight to baseline levels in male and female common marmosets. The behavioral response induced by ayahuasca shows long effect, lasting 14 days. Therefore, for this translational animal model of juvenile depression, it could be proposed that ayahuasca treatment presented more notable antidepressant effects than tricyclic antidepressant nortriptyline, investigated by our group, using this same protocol in an anterior study. Ayahuasca produced faster and more durable effect on reversion of physiological changes and depressive-like symptoms. Therefore, the results found for ayahuasca treatment corroborates in the validation of this substance as an effective antidepressant drug and encourages the return of studies with psychedelic drugs in the treatment of humor disorders, including adolescents with early-age depression.

Ayahuasca: Psychological And Physiologic Effects, Pharmacology And Potential Uses In Addiction And Mental Illness

January 24, 2018 / Ayahuasca, Depressive Disorders, Papers, Psychology, Publications, Substance Use Disorder / By / , , ,

Abstract

Ayahuasca, a traditional Amazonian decoction with psychoactive properties, is made from bark of the Banisteriopsis caapi vine (contains beta-carboline alkaloids) and leaves of the Psychotria viridis bush (supply the hallucinogen N,N-dimethyltryptamine (DMT)). Originally used by indigenous shamans for the purposes of spirit communication, magical experiences, healing, and religious rituals, across several South American countries ayahuasca has been incorporated into folk medicine and spiritual healing, and several Brazilian churches use it routinely to foster spiritual experience. More recently it is being used in Europe and North America, not only for religious or healing reasons, but also for recreation.
OBJECTIVE:
To review ayahuasca’s behavioral effects, possible adverse effects, proposed mechanisms of action and potential clinical uses in mental illness.
METHOD:
We searched Medline, in English, using the terms ayahuasca, dimethytryptamine, Banisteriopsis caapi, and Psychotria viridis and reviewed the relevant publications.
RESULTS:
The following aspects of ayahuasca are summarized: Political and legal factors; acute and chronic psychological effects; electrophysiological studies and imaging; physiological effects, safety and adverse effects; pharmacology; potential psychiatric uses.
CONCLUSION:
Many years of shamanic wisdom have indicated potential therapeutic uses for ayahuasca, and many present day studies suggest that it may be useful for treating various psychiatric disorders and addictions. The side effect profile appears to be relatively mild, but more detailed studies need to be done. Several prominent researchers feel that government regulations with regard to ayahuasca should be relaxed so that it could be provided more readily to recognized credible researchers to conduct comprehensive clinical trials.

Ketamine Use for Suicidal Ideation in the General Hospital: Case Report and Short Review

January 24, 2018 / Depressive Disorders, Ketamine, Papers, Psychology, Publications / By / , , , , , ,

Abstract

Low-dose infusion of ketamine may have rapid antisuicide properties. Such a treatment may therefore be useful in the general hospital to prevent suicide in an environment that cannot be made safe enough. We report on the use of ketamine as an efficient, well-tolerated treatment for persistent suicidal ideation in a patient hospitalized in a general hospital after a severe suicide attempt. Based on data in the literature, we suggest that the benefit-risk ratio for ketamine use in such a context is highly favorable.

Taking Psychedelics Seriously

January 22, 2018 / Anxiety Disorders / PTSD, Depressive Disorders, Ketamine, MDMA, Mushrooms / Psilocybin, Papers, Psychology, Publications / By /

Abstract

Background: Psychiatric research in the 1950s and 1960s showed potential for psychedelic medications to markedly alleviate depression and suffering associated with terminal illness. More recent published studies have demonstrated the safety and efficacy of psilocybin, MDMA, and ketamine when administered in a medically supervised and monitored approach. A single or brief series of sessions often results in substantial and sustained improvement among people with treatment-resistant depression and anxiety, including those with serious medical conditions.

Need and Clinical Considerations: Palliative care clinicians occasionally encounter patients with emotional, existential, or spiritual suffering, which persists despite optimal existing treatments. Such suffering may rob people of a sense that life is worth living. Data from Oregon show that most terminally people who obtain prescriptions to intentionally end their lives are motivated by non-physical suffering. This paper overviews the history of this class of drugs and their therapeutic potential. Clinical cautions, adverse reactions, and important steps related to safe administration of psychedelics are presented, emphasizing careful patient screening, preparation, setting and supervision.

Conclusion: Even with an expanding evidence base confirming safety and benefits, political, regulatory, and industry issues impose challenges to the legitimate use of psychedelics. The federal expanded access program and right-to-try laws in multiple states provide precendents for giving terminally ill patients access to medications that have not yet earned FDA approval. Given the prevalence of persistent suffering and growing acceptance of physician-hastened death as a medical response, it is time to revisit the legitimate therapeutic use of psychedelics.

Can we confidently use ketamine as a clinical treatment for depression?

January 1, 2018 / Depressive Disorders, Ketamine, Papers, Psychology, Publications / By /

Abstract

Findings from several proof-of-concept, double-blinded, placebo-controlled studies have shown rapid and large antidepressant effects in patients with major depression after a single dose of ketamine.1 These data are remarkable in the rapidity of therapeutic effects, with remission within 24 h (though relapse often occurs within days), the high degree of antidepressant potency in cohorts with moderate-to-high treatment resistance, and the consistency of findings between studies. Given that ketamine is readily available in many countries as an approved anaesthetic drug, it is not surprising that there has been enthusiasm for the use of ketamine to treat depression.

Increased nature relatedness and decreased authoritarian political views after psilocybin for treatment-resistant depression

January 1, 2018 / Depressive Disorders, Mushrooms / Psilocybin, Papers, Philosophy & Religious Studies, Publications / By / ,

Abstract

RATIONALE:
Previous research suggests that classical psychedelic compounds can induce lasting changes in personality traits, attitudes and beliefs in both healthy subjects and patient populations.
AIM:
Here we sought to investigate the effects of psilocybin on nature relatedness and libertarian-authoritarian political perspective in patients with treatment-resistant depression (TRD).
METHODS:
This open-label pilot study with a mixed-model design studied the effects of psilocybin on measures of nature relatedness and libertarian-authoritarian political perspective in patients with moderate to severe TRD ( n=7) versus age-matched non-treated healthy control subjects ( n=7). Psilocybin was administered in two oral dosing sessions (10 mg and 25 mg) 1 week apart. Main outcome measures were collected 1 week and 7-12 months after the second dosing session. Nature relatedness and libertarian-authoritarian political perspective were assessed using the Nature Relatedness Scale (NR-6) and Political Perspective Questionnaire (PPQ-5), respectively.
RESULTS:
Nature relatedness significantly increased ( t(6)=-4.242, p=0.003) and authoritarianism significantly decreased ( t(6)=2.120, p=0.039) for the patients 1 week after the dosing sessions. At 7-12 months post-dosing, nature relatedness remained significantly increased ( t(5)=-2.707, p=0.021) and authoritarianism remained decreased at trend level ( t(5)=-1.811, p=0.065). No differences were found on either measure for the non-treated healthy control subjects.
CONCLUSIONS:
This pilot study suggests that psilocybin with psychological support might produce lasting changes in attitudes and beliefs. Although it would be premature to infer causality from this small study, the possibility of drug-induced changes in belief systems seems sufficiently intriguing and timely to deserve further investigation.

Increased amygdala responses to emotional faces after psilocybin for treatment-resistant depression

December 27, 2017 / Depressive Disorders, Mushrooms / Psilocybin, Papers, Psychology, Publications / By / , , , ,

Abstract

Recent evidence indicates that psilocybin with psychological support may be effective for treating depression. Some studies have found that patients with depression show heightened amygdala responses to fearful faces and there is reliable evidence that treatment with SSRIs attenuates amygdala responses (Ma, 2015). We hypothesised that amygdala responses to emotional faces would be altered post-treatment with psilocybin. In this open-label study, 20 individuals diagnosed with moderate to severe, treatment-resistant depression, underwent two separate dosing sessions with psilocybin. Psychological support was provided before, during and after these sessions and 19 completed fMRI scans one week prior to the first session and one day after the second and last. Neutral, fearful and happy faces were presented in the scanner and analyses focused on the amygdala. Group results revealed rapid and enduring improvements in depressive symptoms post psilocybin. Increased responses to fearful and happy faces were observed in the right amygdala post-treatment, and right amygdala increases to fearful versus neutral faces were predictive of clinical improvements at 1-week. Psilocybin with psychological support was associated with increased amygdala responses to emotional stimuli, an opposite effect to previous findings with SSRIs. This suggests fundamental differences in these treatments’ therapeutic actions, with SSRIs mitigating negative emotions and psilocybin allowing patients to confront and work through them. Based on the present results, we propose that psilocybin with psychological support is a treatment approach that potentially revives emotional responsiveness in depression, enabling patients to reconnect with their emotions.

Quality of acute psychedelic experience predicts therapeutic efficacy of psilocybin for treatment-resistant depression

December 20, 2017 / Anxiety Disorders / PTSD, Depressive Disorders, Mushrooms / Psilocybin, Papers, Psychology, Publications / By / , ,

Abstract

Introduction: It is a basic principle of the ‘psychedelic’ treatment model that the quality of the acute experience mediates long-term improvements in mental health. In the present paper we sought to test this using data from a clinical trial assessing psilocybin for treatment-resistant depression (TRD). In line with previous reports, we hypothesized that the occurrence and magnitude of Oceanic Boundlessness (OBN) (sharing features with mystical-type experience) and Dread of Ego Dissolution (DED) (similar to anxiety) would predict long-term positive outcomes, whereas sensory perceptual effects would not.
Material and Methods: Twenty patients with treatment resistant depression underwent treatment with psilocybin (two separate sessions: 10mg and 25mg psilocybin). The Altered States of Consciousness (ASC) questionnaire was used to assess the quality of experiences in the 25mg psilocybin session. From the ASC, the dimensions OBN and DED were used to measure the mystical-type and challenging experiences, respectively. The Self-Reported Quick Inventory of Depressive Symptoms (QIDS-SR) at 5 weeks served as the endpoint clinical outcome measure, as in later time points some of the subjects had gone on to receive new treatments, thus confounding inferences. In a repeated measure ANOVA, Time was the within-subject factor (independent variable), with QIDS-SR as the within-subject dependent variable in baseline, 1-day, 1-week, 5-weeks. OBN and DED were independent variables. OBN-by-time and DED-by-time interactions were the primary outcomes of interest.
Results: For the interaction of OBN and DED with Time (QIDS-SR as dependent variable), the main effect and the effects at each time point compared to baseline were all significant (p = 0.002 and p = 0.003, respectively, for main effects), confirming our main hypothesis. Furthermore, Pearson’s correlation of OBN with QIDS-SR (5 weeks) was specific compared to perceptual dimensions of the ASC (p < 0.05).
Discussion: This report further bolsters the view that the quality of the acute psychedelic experience is a key mediator of long-term changes in mental health. More specifically, future therapeutic work with psychedelics may consider investigating ways which enhance mystical-type experience and reduce anxiety, given the growing evidence that this serves the efficacy of the treatment model.
