The relationship between cannabis use and cognition in people diagnosed with first-episode psychosis.

Psychiatry Research August 23, 2020 Chloé de Vos, Karolina Leopold, Elisabeth S. Blanke et al.

Cannabis use is highly prevalent among young people diagnosed with first-episode psychosis (FEP), however, its impact on cognition is still unclear. The aim of the present study was to examine the association of cannabis use with cognition in people diagnosed with FEP. We extended previous research findings by operationalising the comorbid cannabis use, considering recency of cannabis use and...

Psychiatry Research May 25, 2020 Rongrong Xuan, Xiaoming Li, Yuxi Qiao et al.

BACKGROUND Mindfulness-based cognitive therapy (MBCT) is an increasingly popular treatment for major depression and anxiety disorder, but has shown inconsistent efficacy for bipolar disorder (BD). Therefore, we conducted a meta-analysis to assess the general efficacy of MBCT for BD. METHODS Ten studies were identified that fulfilled the current inclusion criteria, including three controlled and...

Characteristics of non-clinical hallucinations: A mixed-methods analysis of auditory, visual, tactile and olfactory hallucinations in a primary voice-hearing cohort.

Psychiatry Research May 19, 2020 W. L. Toh, N. Thomas, Michelle A. Robertson et al.

Phenomenological studies involving hallucinations in non-clinical populations have been relatively neglected, especially within the non-auditory realm. Relevant knowledge would help further a more nuanced understanding of the psychosis continuum. Participants (N=33) were non-clinical voice-hearers, who have experienced auditory verbal hallucinations, but with no known mental health diagnosis...

Real-time fMRI neurofeedback reduces auditory hallucinations and modulates resting state connectivity of involved brain regions: Part 2: Default mode network -preliminary evidence

Psychiatry Research January 14, 2020 Clemens C C Bauer, Kana Okano, Satrajit Ghosh et al. 87 citations

Auditory hallucinations (AHs) are one of the most distressing symptoms of schizophrenia (SZ) and are often resistant to medication. Imaging studies of individuals with SZ show hyperactivation of the default mode network (DMN) and the superior temporal gyrus (STG). Studies in SZ show DMN hyperconnectivity and reduced anticorrelation between DMN and the central executive network (CEN). DMN...

An epidemiological study on the prevalence of hallucinations in a general-population sample: Effects of age and sensory modality.

Psychiatry Research February 1, 2019 Frank Larøi, Josef J Bless, Julien Laloyaux et al.

Epidemiological studies have repeatedly shown that a significant minority of the general population have experienced hallucinations, however, a potential effect of age on the prevalence of hallucinations in the general population has never been previously examined in a specific study. The aim of the present study was thus to examine the effects of age and sensory modality on hallucination...

Does mindfulness help people adapt to the experience of hearing voices?

Psychiatry Research December 2018 Louise Stephanie, Rossell Susan L, Toh Wei Lin et al.

Mindfulness-based interventions show promise in the treatment of psychotic symptoms. From a theoretical perspective, there may be several benefits of mindfulness for individuals who experience hearing voices. Related cross-sectional findings suggest mindfulness may protect against distress, disruption, negative beliefs, dysfunctional relational style and responding, and mood symptoms for...

Rapid inflammation modulation and antidepressant efficacy of a low-dose ketamine infusion in treatment-resistant depression: A randomized, double-blind control study.

Psychiatry Research November 2018 Mu-Hong Chen, Cheng-Ta Li, Wei-Chen Lin et al.

Increasing evidence supports the rapid antidepressant effect of a low-dose ketamine infusion in treatment-resistant depression (TRD). Proinflammatory cytokines play a crucial role in the pathophysiology of TRD. However, it is unknown whether the rapid antidepressant effect of ketamine is related to the rapid suppression of proinflammatory cytokines. Seventy-one patients with TRD were randomized...

Ketamine ameliorates depressive-like behaviors by tPA-mediated conversion of proBDNF to mBDNF in the hippocampus of stressed rats.

Psychiatry Research November 2018 Fan Zhang, Jie Luo, Xianlin Zhu

Some studies have indicated that ketamine has a rapid antidepressant effects, but the underlying molecular mechanism is still unclear. Researchers have found that mature brain-derived neurotrophic factor (mBDNF) and its precursor proBDNF are related to depression; they elicit opposite effects on cellular functions. It is clear that tissue plasminogen activator (tPA) is a key regulatory element...

Psychosis and synthetic cannabinoids.

Psychiatry Research October 2018 Huiqiong Deng, Christopher D. Verrico, Thomas R Kosten et al.

Synthetic cannabinoid (SC) products have gained popularity as abused drugs over the past decade in many countries.
