This chapter presents a radically renewed vision of psychiatry and psychology, based on the inclusion of the spiritual, energetic, and transformative dimensions of the human being. The author criticizes the technical-materialist drift of modern neuroscience, emphasizing how Western culture has relegated mystical and spiritual experience to exceptional or pathological phenomena, depriving the...
Serotonergic psychedelics are re-emerging as therapeutic candidates across psychiatry, particularly for treatment-resistant depression. Their rapid and sustained antidepressant effects, alongside evidence for neuroplastic, dopaminergic, and glutamatergic modulation, have prompted interest in whether they could address depressive and negative symptoms in schizophrenia spectrum disorders (SSDs)....
Introdução: Os transtornos psiquiátricos representam um importante desafio na saúde pública mundial, com impacto significativo na qualidade de vida, funcionalidade e mortalidade dos pacientes. Embora os psicofármacos tradicionais, como antidepressivos, antipsicóticos e estabilizadores de humor sejam amplamente utilizados, muitos indivíduos apresentam resposta insatisfatória, falha terapêutica...
Psychedelic compounds such as psilocybin, Lysergic Acid Diethylamide (LSD), N,Ndimethyltryptamine (DMT), and 3,4-methylenedioxymethamphetamine (MDMA) are emerging as novel therapeutics for neuropsychiatric disorders, including depression, Post-Traumatic Stress Disorder (PTSD), and addiction. Acting primarily through serotonin 5-HT2A receptor agonism, they activate intracellular cascades...

Abstract Depression and anxiety affect one in five adults, with age affecting prevalence. While clinical trials suggest classic psychedelics (e.g., psilocybin, LSD) and non-classic psychedelics (e.g., MDMA, ketamine) may alleviate these symptoms, it remains unclear how these relationships function in naturalistic settings or how they vary across the lifespan. We conducted a cross-sectional...
BACKGROUND: Hallucinogen use among adolescents is increasing worldwide. In this context, in recent years, hallucinogens have re-emerged in scientific and public discourse. However, whether there is an association between hallucinogens use in adolescents and the impact of such use in individuals with Early-Onset Psychosis (EOP), remains unclear. This systematic review and meta-analysis evaluated...
INTRODUCTION: Recreational drug poisonings pose a growing public health concern. European-level data remain limited, although poison centres are well placed to monitor related health incidents. This study analysed temporal trends in recreational drug poisonings reported to six European poison centres. METHODS: Aggregated retrospective data were collected over four years (2021-2024) from poison...
Support for the legal use of psilocybin mushrooms (23%) is much lower than it is for cannabis (65%), according to a new RAND research report, released Feb. 24. For LSD and 3,4‐methylenedioxymethamphetamine (MDMA)–assisted therapy, support for legal use is closer to 10%.
While interest in the therapeutic and recreational use of hallucinogens has increased, national surveillance often reports use in aggregate, potentially masking shifting trends among pharmacologically distinct substances. This study assessed trends in specific hallucinogens from 2021 to 2023 and identified correlates of use, with particular attention to subgroup patterns in populations commonly...
Sound and hearing play a crucial role in the conceptualisation and perception of divine entities, cultic places, and ritual processes. Sound phenomena can evoke religious experiences, structure ritual communication and stimulate desired emotional responses, whilst exposure to certain resonance frequencies can affect the human body, thereby influencing one’s perceptions and states of...
