Improvements in functioning and workplace productivity with esketamine nasal spray versus quetiapine extended release in patients with treatment resistant depression: Findings from a 32-week randomised, open-label, rater-blinded phase IIIb study.

European Neuropsychopharmacology April 1, 2025 Eduard Vieta, Nahida Ahmed, Celso Arango et al. 12 citations

Patients with treatment resistant depression (TRD) experience a greater negative impact on their functioning and productivity at home and in the workplace versus treatment-responsive patients. Here, we report the effects of esketamine nasal spray (NS) versus quetiapine extended release (XR) on functioning, work productivity and activity impairment. ESCAPE‑TRD (NCT04338321) was a 32-week...

The Effect of Meditation, Mindfulness, and Yoga in Patients with Rheumatoid Arthritis.

Journal of Personalized Medicine November 15, 2022 Laura Slagter, Koen Demyttenaere, Patrick Verschueren et al.

Mind-body therapies (MBTs), including meditation, yoga, and mindfulness, create an interaction between the mind and body to enhance health. MBTs are perceived by both patients and healthcare professionals as valuable in the management of rheumatoid arthritis (RA), but the extent of this contribution is unclear, as are the patient subgroups who benefit most from MBTs. Therefore, this systematic...

Twelve-Week Yoga vs. Aerobic Cycling Initiation in Sedentary Healthy Subjects: A Behavioral and Multiparametric Interventional PET/MR Study

Frontiers in Psychiatry October 18, 2021 June van Aalst, Lise Jennen, Koen Demyttenaere et al. 9 citations

Interventional yoga studies with an active control group remain scarce and are important to clarify the underlying neurobiology. We conducted an interventional study in healthy controls using simultaneous positron emission tomography/magnetic resonance (PET/MR) imaging and psychometric scales. Thirty healthy, female volunteers (28.4 ± 8.4 years) participated and were randomly assigned to a...

What Has Neuroimaging Taught Us on the Neurobiology of Yoga? A Review

Frontiers in Integrative Neuroscience July 8, 2020 June van Aalst, Jenny Ceccarini, Koen Demyttenaere et al. 57 citations

Yoga is becoming increasingly popular worldwide, with several implicated physical and mental benefits. Here we provide a comprehensive and critical review of the research generated from the existing neuroimaging literature in studies of yoga practitioners. We reviewed 34 international peer-reviewed neuroimaging studies of yoga using magnetic resonance imaging (MRI), positron emission tomography...

Long-term Ashtanga yoga practice decreases medial temporal and brainstem glucose metabolism in relation to years of experience

EJNMMI Research May 14, 2020 June van Aalst, Jenny Ceccarini, Georg Schramm et al. 13 citations

BACKGROUND: Yoga is increasingly popular worldwide with several physical and mental benefits, but the underlying neurobiology remains unclear. Whereas many studies have focused on pure meditational aspects, the triad of yoga includes meditation, postures, and breathing. We conducted a cross-sectional study comparing experienced yoga practitioners to yoga-naive healthy subjects using a...

Ketamine: stimulating antidepressant treatment?

BJPsych Open May 1, 2016 Gin S. Malhi, Yulisha Byrow, Frederick Cassidy et al. 31 citations

SUMMARY: The appeal of ketamine - in promptly ameliorating depressive symptoms even in those with non-response - has led to a dramatic increase in its off-label use. Initial promising results await robust corroboration and key questions remain, particularly concerning its long-term administration. It is, therefore, timely to review the opinions of mood disorder experts worldwide pertaining to...
