Ketamine in psychiatry: Ethical imperatives in harnessing a controversial yet promising therapy

Australian & New Zealand Journal of Psychiatry December 11, 2025 Adem T. Can, Jim Lagopoulos, Paul B Fitzgerald et al. 2 citations

Ketamine has emerged as a rapid-acting intervention for treatment-resistant psychiatric disorders, generating both enthusiasm and unease. While evidence demonstrates robust antidepressant, anxiolytic and anti-suicidal effects, ketamine also carries risks, including dissociation, dependence and uncertain long-term safety. Its reputation as a recreational drug further complicates clinical...

Economic evaluation of subcutaneous ketamine injections for treatment resistant depression: A randomised, double-blind, active-controlled trial - The KADS study.

Journal of Affective Disorders October 15, 2025 Mary Lou Chatterton, Johana Kevin Perez, Thao Thai et al. 2 citations

Ketamine is effective for treatment resistant depression (TRD); but cost-effectiveness evidence remains limited. To evaluate the cost-effectiveness of subcutaneous ketamine for TRD from health sector and societal perspectives. A cost-utility analysis alongside the KADS randomised controlled trial (RCT) involved 174 participants receiving ketamine or midazolam (active control) twice weekly for 4...

Experienced meditators show greater forward traveling cortical alpha wave strengths.

Annals of the New York Academy of Sciences July 2, 2025 Neil W. Bailey, Aron T. Hill, Kate Godfrey et al. 4 citations

Mindfulness meditation involves training attention, commonly toward sensory experiences, with nonjudgmental awareness. Theoretical perspectives propose that meditation increases the precision of sensory processing and reduces the generation/elaboration of top-down expectations. Research suggests forward traveling cortical alpha waves may reflect bottom-up inhibition to enhance signal-to-noise...

Effect of ketamine on anxiety: findings from the Ketamine for Adult Depression Study.

The British journal of psychiatry : the journal of mental science January 7, 2025 Natalie T Mills, Stevan Nikolin, Nick Glozier et al. 3 citations Retracted

Anxiety disorders and treatment-resistant major depressive disorder (TRD) are often comorbid. Studies suggest ketamine has anxiolytic and antidepressant properties. To investigate if subcutaneous racemic ketamine, delivered twice weekly for 4 weeks, reduces anxiety in people with TRD. The Ketamine for Adult Depression Study was a multisite 4-week randomised, double-blind, active...

Uncovering a stability signature of brain dynamics associated with meditation experience using massive time-series feature extraction.

Neural networks : the official journal of the International Neural Network Society March 1, 2024 Neil W. Bailey, Ben D Fulcher, Bridget Caldwell et al. 7 citations

Previous research has examined resting electroencephalographic (EEG) data to explore brain activity related to meditation. However, previous research has mostly examined power in different frequency bands. The practical objective of this study was to comprehensively test whether other types of time-series analysis methods are better suited to characterize brain activity related to meditation....

The prescription of psychedelic therapies in Australia and New Zealand: A brief survey of psychiatrists.

Australas Psychiatry February 13, 2023 Joshua J Berger, Paul B Fitzgerald 19 citations

OBJECTIVE: To explore the knowledge and attitudes of psychiatrists about psychedelics therapies. METHOD: Access to a cross-sectional survey was distributed to psychiatrists through social media channels. Attitudes and knowledge about psychedelic therapies were recorded using Likert scales and ranking questions. RESULTS: Fifty-eight complete responses were collected (44 fully trained +14 trainee...

Meditators probably show increased behaviour-monitoring related neural activity

bioRxiv Preprint Server July 7, 2022 Neil W. Bailey, Harry Geddes, Isabella Zannettino et al. 5 citations preprint

Objectives Mindfulness meditation is associated with better attention function. Performance monitoring and error-processing are important aspects of attention. We investigated whether experienced meditators showed different neural activity related to performance monitoring and error-processing. Previous research has produced inconsistent results. This study used more rigorous analyses and a...
