Psilocybin for Treatment-Resistant OCD: A Randomized Controlled Trial
OpenAlex – January 15, 2026
Summary
A single dose of psilocybin, a potent hallucinogen, dramatically reduced severe obsessive compulsive symptoms. In a randomized controlled trial, 69.2% of 13 adults with treatment-resistant OCD experienced significant symptom reduction within one week, against 0% on niacin. This medicine, a focus in pharmacology and psychedelics studies, showed an impressive effect size (Cohen's d=1.64), with scores decreasing by 9.83 points. While one serious adverse effect occurred, these clinical trial findings in internal medicine and psychiatry suggest a novel approach for a population often struggling with major depressive disorder.
Abstract
Background: Obsessive-compulsive disorder (OCD) affects 2-3% of the population worldwide. 40-60% of patients do not respond to first-line intervent...
Psilocybin rapidly, but not immediately, reverses reward learning deficits in a durable manner in an inflammatory rat model of depressive symptoms
OpenAlex – January 15, 2026
Summary
A single 0.3 mg/kg dose of the hallucinogen psilocybin rapidly reverses anhedonia, a core depressive symptom, in a rat model. This psychedelic compound, affecting serotonergic pathways, restored blunted reward processing within 24 hours, with antidepressant effects lasting over 7 days. This neuroscience and pharmacology insight suggests psilocybin's potential as a new medicine for depression, offering hope for improved psychological treatments. Psilocybin, a key focus in Psychedelics and Drug Studies, demonstrates sustained benefits.

Effectiveness of Anapanasati Meditation on Internal Locus of Control, Psychological Well-being, Resilience and Altruism Among Orphan Adolescents.
Annals of neurosciences – January 10, 2026
Summary
Anapanasati meditation significantly boosts well-being, altruism, and internal locus of control among vulnerable orphan adolescents. A three-month program, implemented with 54 orphan adolescents (compared to 54 non-orphan peers aged 13-17), demonstrated marked improvements in resilience from the second month. This simple, low-cost meditation effectively supports holistic growth, enhancing positive psychosocial performance for adolescents facing unique challenges. It offers a practical solution for resource-constrained settings, fostering a stronger sense of self-direction and compassion.
Abstract
Orphan adolescents face multiple vulnerabilities, including a lack of parental guidance, poor educational opportunities, socio-economic disadvantag...
Ibogaine for the treatment of Parkinson's disease: A case report
Journal of Psychedelic Studies – January 06, 2026
Summary
Low-dose ibogaine hydrochloride may offer hope for improving symptoms in Parkinson's disease (PD). In an 80-day treatment of a 52-year-old female patient, significant enhancements were noted across four out of five clinical assessments: motor symptoms improved by 54%, quality of life increased by 42%, fatigue decreased by 38%, and depression scores fell by 30%. Notably, sleep quality declined, likely due to ibogaine's stimulant effects. Remarkably, no adverse effects were reported, suggesting potential for ibogaine as a novel therapeutic avenue in managing PD symptoms.

Factors for predicting response to electroconvulsive therapy (ECT), transcranial magnetic stimulation (TMS) and ketamine in patients with treatment-resistant depression: a systematic review
Figshare – January 01, 2026
Summary
Electroconvulsive therapy (ECT), repetitive transcranial magnetic stimulation (rTMS), and ketamine treatments show promise for treatment-resistant depression (TRD), yet predicting patient responses remains challenging. Out of 408 studies screened, 42 met inclusion criteria, with 23 focusing on ketamine, 14 on rTMS, and 11 on ECT. Factors such as symptom profiles and inflammation markers were explored, but inconsistencies prevailed. Current evidence offers weak support for specific predictors, highlighting the need for larger comparative studies to enhance clinical decision-making in TRD management.
