Neuroplastic white matter changes in patients with major depression following lysergic acid diethylamide treatment

Cell Reports Medicine May 7, 2026 Mihai Avram, Aurore Menegaux, Felix Müller et al. 1 citation

The clinical trial NCT03866252 investigates the antidepressant effects of lysergic acid diethylamide (LSD) in 61 patients with major depressive disorder (MDD) randomized to low-dose LSD (LD-LSD; 2 × 25 μg) or moderate-to-high-dose LSD (HD-LSD; 100 μg followed by 200 μg) 4 weeks apart. Although the trial reports positive clinical outcomes, underlying mechanisms remain unclear. Here, we test...

Psychedelics distinctly alter brain entropy and complexity compared to psychostimulants

medRxiv January 16, 2026 Kristian Larsen, Patrick M. Fisher, Drummond E. Mcculloch et al. 1 citation

Classical psychedelics have regained interest for their potential to treat psychiatric and neurological disorders, and explore neural mechanisms supporting perception, cognition, and mood. Acute psychedelic effects have been linked to increases in brain complexity and entropy, but it is unclear if these changes are specific to psychedelics or reflect more general psychoactive effects. Here, we...

Meditation, psychedelics, and brain connectivity: A randomized controlled resting-state fMRI study of N,N-dimethyltryptamine and harmine in a meditation retreat.

Meditation, psychedelics, and brain connectivity: A randomized controlled resting-state fMRI study of N,N-dimethyltryptamine and harmine in a meditation retreat.

Meditation, psychedelics, and brain connectivity: A randomized controlled resting-state fMRI study of N,N-dimethyltryptamine and harmine in a meditation retreat

Universität Zürich, ZORA September 29, 2025 Klemens Egger, Daniel Meling, Firuze Polat et al.

Both meditation and psychedelics are widely studied for their therapeutic potential in mental health. Recent research suggests potential synergies between mindfulness practice and psychedelics, though empirical studies have primarily focused on psilocybin. This study investigates the distinct and combined effects of mindfulness practice and an ayahuasca-inspired formulation containing...

Psychedelics for major depression-From controlled research settings into broader clinical use.

Cell Rep Med September 1, 2025 Mihai Avram, Stefan Borgwardt

Psychedelics have shown promising antidepressant effects in recent phase 2 randomized controlled trials, with phase 3 studies underway. While therapeutic outcomes are encouraging, the underlying mechanisms—from receptor-level pharmacology to subjective experience and context—remain only partially understood. We highlight clinical and mechanistic advances and outline priorities for future...

Large-scale brain connectivity changes following the administration of lysergic acid diethylamide, d-amphetamine, and 3,4-methylenedioxyamphetamine.

Molecular Psychiatry April 1, 2025 Mihai Avram, Lydia Fortea, Lea Wollner et al. 26 citations

Psychedelics have recently attracted significant attention for their potential to mitigate symptoms associated with various psychiatric disorders. However, the precise neurobiological mechanisms responsible for these effects remain incompletely understood. A valuable approach to gaining insights into the specific mechanisms of action involves comparing psychedelics with substances that have...

Effective Connectivity of Thalamocortical Interactions Following d-Amphetamine, LSD, and MDMA Administration.

Biological psychiatry. Cognitive neuroscience and neuroimaging May 1, 2024 Mihai Avram, Felix Müller, Katrin H. Preller et al. 13 citations

While the exploration of serotonergic psychedelics as psychiatric medicines deepens, so does the pressure to better understand how these compounds act on the brain. We used a double-blind, placebo-controlled, crossover design and administered lysergic acid diethylamide (LSD), 3,4-methylenedioxymethamphetamine (MDMA), and d-amphetamine in 25 healthy participants. By using spectral dynamic causal...

Für ein besseres Verständnis anhaltender Wahrnehmungsstörungen nach der Einnahme klassischer Psychedelika

Fortschritte der Neurologie · Psychiatrie April 1, 2024 Stefan Borgwardt, Tomislav Majić, Mihai Avram et al.

Klassische Psychedelika wie Psilocybin, Lysergsäurediethylamid (LSD), Ayahuasca oder 5-Methoxy-Dimethyltryptamin (5-MeO-DMT) stehen wieder vermehrt im Fokus des psychiatrisch-psychotherapeutischen und neurowissenschaftlichen Interesses. Dies ist vor allem auf aktuelle klinische Studien zurückzuführen, die einen möglichen therapeutischen Nutzen von Psychedelika in der Behandlung verschiedener...

Lysergic acid diethylamide: In search of the wonder drug

Psychedelics as Psychiatric Medications March 1, 2023 Mihai Avram, Felix Müller, Stefan Borgwardt 1 citation

Abstract Lysergic acid diethylamide (LSD) is a potent perception-altering chemical. Since the discovery of its effects almost eighty years ago, LSD has been revered and demonized. Before its ban in the late 1960s, LSD was used to model aspects of psychosis and treat distinct mental disorders such as alcohol addiction and anxiety. The new wave of research on psychedelics as potential treatments...

Characterizing Thalamocortical (Dys)connectivity Following D-Amphetamine, LSD, and MDMA Administration

Biological Psychiatry Cognitive Neuroscience and Neuroimaging April 29, 2022 Mihai Avram, Felix Müller, Helena Rogg et al. 43 citations

Psychedelics, empathogens, and psychostimulants evoke thalamocortical hyperconnectivity with sensorimotor areas, akin to findings in patients with psychotic disorders.

Bridging the Gap? Altered Thalamocortical Connectivity in Psychotic and Psychedelic States

Frontiers in Psychiatry October 13, 2021 Mihai Avram, Helena Rogg, Αλεξάνδρα Κορδά et al. 43 citations

Psychiatry has a well-established tradition of comparing drug-induced experiences to psychotic symptoms, based on shared phenomena such as altered perceptions. The present review focuses on experiences induced by classic psychedelics, which are substances capable of eliciting powerful psychoactive effects, characterized by distortions/alterations of several neurocognitive processes (e.g.,...
