A century of research on psychedelics: A scientometric analysis on trends and knowledge maps of hallucinogens, entactogens, entheogens and dissociative drugs.

European neuropsychopharmacology : the journal of the European College of Neuropsychopharmacology November 1, 2022 Marco Solmi, Chaomei Chen, Charles Dauré et al. 55 citations

Over the past century, clinical research on psychedelics has evolved from an early focus on safety into a 'psychedelic renaissance' after the 1990s. A scientometric analysis of 31,687 documents from the Web of Science identified major research themes: hallucinogens/entheogens, entactogens, novel psychoactive substances (NPS), and dissociative substances. The field has shifted from basic science to clinical applications, including phase 2 and 3 trials and evidence synthesis. Recent trends include NPS, ketamine-associated brain changes, and ayahuasca-assisted psychotherapy. The USA and Canada lead in productivity, reflecting legislative influences. This translational evolution has already led to esketamine approval for depression and may lead to further approvals across mental and physical conditions. Toxicology screening tools for NPS are urgently needed and may follow a similar path.

Half a Century of Research on Posttraumatic Stress Disorder: A Scientometric Analysis.

Current neuropharmacology January 1, 2024 Michel Sabé, Chaomei Chen, Wissam El-Hage et al. 25 citations

A scientometric analysis of 42,170 publications on posttraumatic stress disorder (PTSD) from 1945 to 2022 identified four major research trends: war veterans and refugees, treatment of PTSD/neuroimaging, evidence syntheses, and somatic symptoms of PTSD. The largest cluster focused on evidence synthesis for genetic predisposition and environmental exposures leading to PTSD. War-related trauma research has shifted from battlefield in-person exposure to drone operator trauma and is being outpaced by civilian trauma research, including the COVID-19 pandemic, postpartum, and grief disorder. Recent trends show a burst in PTSD treatment research involving Mhealth, virtual reality, and psychedelic drugs. The USA dominates collaboration networks, with a recent surge of publications from China. Compared to other psychiatric disorders, there is a lack of high-quality randomized controlled trials for pharmacological and nonpharmacological treatments.
