Psilocybin is a classic psychedelic compound that may have efficacy for the treatment of mood and substance use disorders. Acute psilocybin effects include reduced negative mood, increased positive mood, and reduced amygdala response to negative affective stimuli. However, no study has investigated the long-term, enduring impact of psilocybin on negative aff...
BACKGROUND: The repeated use of small doses of psychedelics such as psilocybin and lsd over a period of time (microdosing, md) has gained popularity and scientific attention in recent years. Retrospective reports from users suggest clinical potential. AIM: To answer the question whether md with psychedelics could theoretically provide symptom relief for peop...
Serotoninergic hallucinogens include drugs such as lysergic acid diethylamide (LSD), dimethyltryptamine (DMT) and psilocybin. Recent trials with single/few doses of these compounds show that they induce rapid and sustained antidepressive, anxiolytic, and antiaddictive effects. These effects are also observed in religious groups using the DMT-containing brew ...

Objective: The purpose of the present study was to obtain patient information across a wide geography about medical history, drug use, symptoms, and treatments of individuals diagnosed with hallucinogen persisting perception disorder (HPPD). Methods: The study was an internet survey that yielded 26 HPPD patients from North America (81%), Europe (12%), and So...
BackgroundRecognition of emotions in facial expressions (REFE) is a key aspect of social cognition. Anxiety and mood disorders are associated with deficits in REFE, and anxiolytics and antidepressants reverse these deficits. Recent studies have shown that serotonergic hallucinogens (i.e. ayahuasca, dimethyltryptamine, psilocybin, lysergic acid diethylamide [...
The use of classical psychedelics in a therapy setting can have a positive impact on many different psychiatric disorders such as mood disorders, anxiety, addiction, and overall spiritual wellbeing (Carhart-Harris et al., 2017). However, medicinal psychedelics have been stigmatized and removed as an option of treatment, just as medical cannabis once was. If ...
Depression is one of the most disabling and prevalent mental disorders, which causes excessive feelings of sadness and despair. Unfortunately, there are a substantial number of patients that do not respond well to conventional interventions and new approaches are therefore needed. Recent studies have revealed that psilocybin can effectively reduce symptoms o...
Serotonin is a key neuromodulator known to be involved in brain development, perception, cognition, and mood. However, unlike as with dopamine for example, a compelling unified theory of brain serotonin function has not yet been established. This is likely due to the exceptional complexity of the serotonin system, with its 14+ receptors, over twice the numbe...
Depression and anxiety are psychiatric diagnoses commonly associated with low quality of life and low percentage of responsiveness by patients treated with currently available drugs. Thus, research into alternative compounds to treat these disorders is essential to guarantee a patient's remission. The last decade has witnessed a revamped interest for the app...
IntroductionMood, anxiety, and substance-use disorders are among the most prevalent psychiatric disorders in the population. Although several pharmacological treatments are available, they are not effective for a significant proportion of patients and are associated with several adverse reactions. Therefore, new treatments should be explored. Recent studies ...
In the past decade, an increasing number of clinical trials are reporting evidence that psychedelics or serotonergic hallucinogens (such as lysergic acid diethylamide, psilocybin, and ayahuasca/dimethyltryptamine) could be effective in the treatment of mood, anxiety, and substance use disorders. The mechanisms responsible for these effects are not fully unde...
BackgroundNatural speech analytics has seen some improvements over recent years, and this has opened a window for objective and quantitative diagnosis in psychiatry. Here, we used a machine learning algorithm applied to natural speech to ask whether language properties measured before psilocybin for treatment-resistant can predict for which patients it will ...
Our creativity is challenged daily when facing new situations asking for novel solutions. Creativity, a multicomponent construct includes flexible divergent and rigid convergent thinking. Psychedelic drugs like psilocybin can enhance creativity and affect state of mind (mood, empathy, openness). Of note, flexible thinking is disturbed in psychopathological c...
RationaleRecent 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.ObjectivesThe present study assessed the influence of music on the ac...
Controlled clinical trials using LSD, psilocybin, ayahuasca to treat major mood disorders and addictions have recentlyachieved significant results. Psychedelic drugs cause acute alterations in visual object perception, where object borderswithin the visual scene exhibit illusory rhythmic movements. What is the relationship between the perceptual effectsand t...
This chapter reviews what is known about the therapeutic uses of the serotonergic or classic hallucinogens, i.e., psychoactive drugs such as LSD and psilocybin that exert their effects primarily through agonist activity at serotonin 2A (5HT2A) receptors. Following a review of the history of human use and scientific study of these drugs, the data from clinica...
The classical psychedelic drugs, including psilocybin, lysergic acid diethylamide and mescaline, were used extensively in psychiatry before they were placed in Schedule I of the UN Convention on Drugs in 1967. Experimentation and clinical trials undertaken prior to legal sanction suggest that they are not helpful for those with established psychotic disorder...
Mental illness is a public health crisis. Millions of Americans suffer through their days crippled by symptoms of mood, anxiety, and substance use disorders. These conditions take large social and economic tolls on our communities. However, the medicines used to treat them have remained largely unchanged for over fifty years. Though helpful to many people, t...
