Combination of non-invasive brain stimulation with mindfulness-based interventions for anxiety and depression symptoms: systematic review and meta-analysis of randomized controlled trials.

European Archives of Psychiatry and Clinical Neuroscience November 17, 2024 Anastasia Demina, Benjamin Petit, Vincent Meille et al. 6 citations

In this article we aimed synthesize all available evidence regarding the effects of non-invasive brain stimulation (NIBS) techniques combined with mindfulness-based interventions (MBIs) on mental health indicators. We performed a systematic review of randomized controlled trials evaluating NIBS/MBIs combinations in clinical populations and a random effects pairwise meta-analysis of studies...

Neurobiological Changes Induced by Mindfulness and Meditation: A Systematic Review.

Biomedicines November 15, 2024 Andrea Calderone, Desirèe Latella, Federica Impellizzeri et al. 83 citations

Background and Objectives: Meditation and mindfulness, rooted in ancient traditions, enhance mental well-being by cultivating awareness and emotional control. It has been shown to induce neuroplasticity, increase cortical thickness, reduce amygdala reactivity, and improve brain connectivity and neurotransmitter levels, leading to improved emotional regulation, cognitive function, and stress...

Understanding the variability in ketamine’s efficacy in managing treatment-resistant depression

Discover Psychology November 3, 2024 Joshua W. Bryan 3 citations

Abstract Ketamine, often associated with its frequent illicit recreational use, is renowned as an approved alternative for treatment-resistant depression. This paper evaluates the mechanism of ketamine’s role in treating depression, emphasising its positive safety profile and acute onset of action. Ketamine’s mechanism of action involves antagonism of N-methyl-D-Aspartate (NMDA) receptors,...

KETAMINE: Neural- and network-level changes.

Neuroscience November 1, 2024 Vishal Bharmauria, Hamidreza Ramezanpour, Afef Ouelhazi et al.

Ketamine is a widely used clinical drug that has several functional and clinical applications, including its use as an anaesthetic, analgesic, anti-depressive, anti-suicidal agent, among others. Among its diverse behavioral effects, it influences short-term memory and induces psychedelic effects. At the neural level across different brain areas, it modulates neural firing rates, neural tuning,...

Rethinking the role of TRKB in the action of antidepressants and psychedelics.

Trends in Neurosciences November 1, 2024 Cecilia Anna Brunello, Cecilia Cannarozzo, Eero Castrén 29 citations

Antidepressant drugs promote neuronal plasticity, and activation of brain-derived neurotrophic factor (BDNF) signaling through its receptor neuronal receptor tyrosine kinase 2 (NTRK2 or TRKB) is among the critical steps in this process. These mechanisms are shared by typical slow-acting antidepressants, fast-acting ketamine, and psychedelic compounds, although the cellular targets of each drug...

Challenges and rewards of in vivo synaptic density imaging, and its application to the study of depression.

Neuropsychopharmacology November 1, 2024 Ruth H Asch, Chadi G. Abdallah, Richard E. Carson et al. 11 citations

The development of novel radiotracers for Positron Emission Tomography (PET) imaging agents targeting the synaptic vesicle glycoprotein 2 A (SV2A), an integral glycoprotein present in the membrane of all synaptic vesicles throughout the central nervous system, provides a method for the in vivo quantification of synaptic density. This is of particular interest in neuropsychiatric disorders given...

Psilocybin-assisted neurofeedback for the improvement of executive functions: a randomized semi-naturalistic-lab feasibility study

Philosophical transactions of the Royal Society of London. Series B, Biological sciences October 21, 2024 Stefanie Enriquez‐geppert, Jaroslav Krc, Fiachra O'Higgins et al. 5 citations

Executive function deficits, common in psychiatric disorders, hinder daily activities and may be linked to diminished neural plasticity, affecting treatment and training responsiveness. In this pioneering study, we evaluated the feasibility and preliminary efficacy of psilocybin-assisted frontal-midline theta neurofeedback (NF), a neuromodulation technique leveraging neuroplasticity, to improve...

GluN2B on Adult-Born Granule Cells Modulates (R,S)-Ketamine's Rapid-Acting Effects in Mice.

The International Journal of Neuropsychopharmacology October 1, 2024 Nicholas E Bulthuis, Josephine C McGowan, Liliana R Ladner et al. 2 citations

Standard antidepressant treatments often take weeks to reach efficacy and are ineffective for many patients. (R,S)-ketamine, an N-methyl-D-aspartate (NMDA) receptor antagonist, has been shown to be a rapid-acting antidepressant and to decrease depressive symptoms within hours of administration. While previous studies have shown the importance of the GluN2B subunit of the NMDA receptor on...

Synaptic basis of rapid antidepressant action.

European Archives of Psychiatry and Clinical Neuroscience September 29, 2024 Ege T Kavalali, Lisa M Monteggia 4 citations

The discovery of ketamine's rapid antidepressant action has generated intense interest in the field of neuropsychiatry. This discovery demonstrated that to alleviate the symptoms of depression, treatments do not need to elicit substantive alterations in neuronal circuitry or trigger neurogenesis, but rather drive synaptic plasticity mechanisms to compensate for the underlying pathophysiology....

Psychedelics: A review of their effects on recalled aversive memories and fear/anxiety expression in rodents

Neuroscience & Biobehavioral Reviews September 20, 2024 Isabel Werle, Leandro J Bertoglio 17 citations

Threatening events and stressful experiences can lead to maladaptive memories and related behaviors. Existing treatments often fail to address these issues linked to anxiety/stress-related disorders effectively. This review identifies dose ranges associated with specific actions across various psychedelics. We examined psilocybin/psilocin, lysergic acid diethylamide (LSD),...
