This study explores neurochemical changes in the brain during hypnosis, targeting the parieto-occipital (PO) and posterior superior temporal gyrus (pSTG) regions using proton magnetic resonance spectroscopy (MRS). We examined 52 healthy, hypnosis experienced participants to investigate how two different hypnotic states of varying depth impacted brain neurochemistry in comparison to each other and to their respective non-hypnagogic control conditions. Alongside neurochemical assessments, we recorded respiration and heart rate variability (HRV) to further explore possible associations between physiological correlates of hypnotic depth.

Article Synopsis
  • The study aimed to evaluate the quality of psychiatric discharge summaries (DS) written by the AI ChatGPT-4 compared to those written by psychiatric residents.
  • Results showed that human-written summaries were rated significantly higher than AI-generated ones, with statistical significance in most evaluated categories.
  • While AI DS did not fully match the quality of human-written summaries, they demonstrated potential for use as templates or starting points that could save physicians time in documentation.

Article Synopsis
  • Negative symptoms (NS) in schizophrenia spectrum disorders (SSD) and bipolar disorder I (BD-I) have been linked to issues in working memory, but research on their connections to other clinical factors is limited.
  • In a study with 50 participants from SSD and 49 from BD-I, NS were evaluated using SANS scores focusing on areas like avolition-apathy and anhedonia-asociality, while relationships to symptoms and antipsychotic medication were analyzed through regression methods.
  • Results indicated that disorganization correlates with specific negative symptoms, and avolition-apathy notably predicts worse working memory across both disorders, suggesting the need for further understanding of how NS affects cognitive function in these conditions.

Article Synopsis
  • A history of depression is a significant predictor for developing perinatal depression (fePND), but factors influencing first-time depression during this period are not well understood.
  • This study looked at how allergies and related blood parameters impact perinatal depression using data from CoLaus|PsyCoLaus.
  • The findings suggest that new cases of depression during the perinatal period are linked to a history of allergies and higher levels of certain immune cells, indicating that immune function may influence the risk for fePND and could help inform prevention strategies.

Article Synopsis
  • The study looked at how stopping antidepressant medicine affects a part of the brain called the amygdala that reacts to sad or negative faces.
  • It aimed to find out if this change in brain activity is connected to people becoming depressed again after they stop taking their medication.
  • The research involved tracking 83 patients who had previously been treated for depression and monitored them for 6 months after they stopped their meds to see if they relapsed into depression.

Background: Neuropsychiatric symptoms (NPS) are common in older people, may occur early in the development of dementia disorders, and have been associated with faster cognitive decline. Here, our objectives were to investigate whether plasma levels of neurofilament light chain (NfL), glial fibrillary acid protein (GFAP), and tau phosphorylated at threonine 181 (pTau181) are associated with current NPS and predict future NPS in non-demented older people. Furthermore, we tested whether the presence of NPS combined with plasma biomarkers are useful to predict Alzheimer's disease (AD) pathology and cognitive decline.

Serotonergic psychedelics hold promise as a treatment modality for various psychiatric disorders and are currently applied in psychedelic-assisted psychotherapy. We investigated the learning effects of the serotonin receptor agonist psilocybin in a probabilistic cue-reward task with emotional cues in the form of neutral or fearful faces, presented either consciously or subconsciously. This study represents the first investigation into reinforcement learning with psilocybin.

Background: Psychotherapies, such as cognitive behavioral therapy (CBT), currently have the strongest evidence of durable symptom changes for most psychological disorders, such as anxiety disorders. Nevertheless, only about half of individuals treated with CBT benefit from it. Predictive algorithms, including digital assessments and passive sensing features, could better identify patients who would benefit from CBT, and thus, improve treatment choices.

In this study, for the first time, we explored a dataset of functional magnetic resonance images collected during focused attention and open monitoring meditation before and after a five-day psilocybin-assisted meditation retreat using a recently established approach, based on the Mapper algorithm from topological data analysis. After generating subject-specific maps for two groups (psilocybin vs. placebo, 18 subjects/group) of experienced meditators, organizational principles were uncovered using graph topological tools, including the optimal transport (OT) distance, a geometrically rich measure of similarity between brain activity patterns.

The recent introduction of new-generation immunoassay methods allows the reliable quantification of structural brain markers in peripheral matrices. Neurofilament light chain (NfL), a neuron-specific cytoskeletal component released in extracellular matrices after neuroaxonal impairment, is considered a promising blood marker of active brain pathology. Given its sensitivity to a wide range of neuropathological alterations, NfL has been suggested for the use in clinical practice as a highly sensitive, but unspecific tool to quantify active brain pathology.
