Persisting perceptual abnormalities in psychedelic users are associated with conditioned hallucinations and impaired sensory processing

bioRxiv (Cold Spring Harbor Laboratory) August 16, 2026 Maximillian Greenwald, Peter Thestrup Waade, Eren Kafadar et al. preprint

Abstract Serotonergic psychedelics (SP) are increasingly used in clinical research and naturalistic settings, but their psychotic-like side effects, including persisting perceptual abnormalities (PPAs), are poorly understood. Psychosis-associated hallucinations are associated with susceptibility to conditioned hallucinations and computationally-estimated overweighting of perceptual...

Effects of Psychedelic Drug Use on Neurocognitive Function and Psychological and Social Quality of Life Domains: An International Online Study

medRxiv August 28, 2025 Franziska Stadler, Johan Saelens, Ioline D. Henter et al. preprint

This international online study (N=759) examined the acute, subacute, and long-term effects of psychedelic drug use on cognitive performance and mental health. Participants completed cognitive tasks assessing working memory, selective attention, and visual/spatial perception, as well as questionnaires assessing mental health outcomes and quality of life. Based on self-reported substance use,...

Inflammation, stress and depression: an exploration of ketamine’s therapeutic profile

Drug Discovery Today February 1, 2023 J. Johnston, Maximillian Greenwald, Ioline D. Henter et al. 64 citations

Well-established animal models of depression have described a proximal relationship between stress and central nervous system (CNS) inflammation – a relationship mirrored in the peripheral inflammatory biomarkers of individuals with depression. Evidence also suggests that stress-induced proinflammatory states can contribute to the neurobiology of treatment-resistant depression. Interestingly,...

Ketamine and Serotonergic Psychedelics: Common Mechanisms Underlying the Effects of Rapid-Acting Antidepressants

The International Journal of Neuropsychopharmacology November 16, 2020 Bashkim Kadriu, Maximillian Greenwald, Ioline D. Henter et al. 98 citations

BACKGROUND: The glutamatergic modulator ketamine has created a blueprint for studying novel pharmaceuticals in the field. Recent studies suggest that "classic" serotonergic psychedelics (SPs) may also have antidepressant efficacy. Both ketamine and SPs appear to produce rapid, sustained antidepressant effects after a transient psychoactive period. METHODS: This review summarizes areas of...
