Impaired mnemonic discrimination in children and adolescents at risk for schizophrenia
People with schizophrenia and their high-risk, first-degree relatives report widespread episodic memory impairments that are purportedly due, at least in part, to failures of mnemonic discrimination. Here, we examined the status of mnemonic discrimination in 36 children and adolescents (aged 11-17 years) with and without familial risk for schizophrenia by employing an object-based recognition task … Read more

Aperiodic Neural Activity is a Better Predictor of Schizophrenia than Neural Oscillations
Diagnosis and symptom severity in schizophrenia are associated with irregularities across neural oscillatory frequency bands, including theta, alpha, beta, and gamma. However, electroencephalographic signals consist of both periodic and aperiodic activity characterized by the (1/fX) shape in the power spectrum. In this paper, we investigated oscillatory and aperiodic activity differences between patients with schizophrenia and … Read more

Associations of alcohol and cannabis use with change in posttraumatic stress disorder and depression symptoms over time in recently trauma-exposed individuals
In this study involving recent trauma-exposed civilians, researchers aimed to understand the complex relationship between substance use, posttraumatic stress disorder (PTSD), and depression. They utilized a large multisite dataset and tracked alcohol and cannabis use trajectories as well as PTSD and depression symptoms over a span of 3 months. The study identified three trajectory classes … Read more

Anxiety Screening: Evidence Report and Systematic Review for the US Preventive Services Task Force.
Evidence was insufficient to draw conclusions about the benefits or harms of anxiety screening programs. However, clear evidence exists that treatment for anxiety is beneficial, and more limited evidence indicates that some anxiety screening instruments have acceptable accuracy to detect generalized anxiety disorder.

Aperiodic Neural Activity is a Better Predictor of Schizophrenia than Neural Oscillations
EEG signals consist of both periodic and aperiodic activity, characterized by the (1/fX) shape in the power spectrum but the utility of this activity has not been examined in a task between schizophrenia patients and healthy control participants. We discovered that the steepness of the power spectrum better-predicted group status than traditional band-limited oscillatory power … Read more

Striatal dopamine in anhedonia: A simultaneous [11C]raclopride positron emission tomography and functional magnetic resonance imaging investigation
This study used to simultaneous PET-MR to detect reduced striatal dopamine functioning during reward processing and blunted mesocorticolimbic network functional connectivity in a transdiagnostic sample with clinically significant anhedonia.

Handbook of Self-Compassion
This handbook examines contemporary issues in self-compassion science and practice. It describes advances in the conceptualization and measurement of self-compassion as well as current evidence from cross-sectional and experimental research. The volume addresses the foundational issues of self-compassion, including its relationship to self-esteem and mindfulness. In addition, it considers the developmental origins of self-compassion and … Read more

Day-to-day individual alpha frequency variability measured by a mobile EEG device relates to anxiety
Investigators used an at-home EEG recording device to monitor the changes in individual alpha frequency (IAF), a unique brain activity signature in the 8-12 Hz frequency band. IAF day-to-day variability was found to be stable over a 1 month period and was also found to be related to trait anxiety.

Balancing the Roles of Clinicians and Police in Separating Firearms from People in a Dangerous Mental Health Crisis: Legal Rules, Policy Tools, and Ethical Considerations
As our country aims to implement measures to decrease suicide, of which over half are due to firearms, we explore the role of ERPO (Extreme Risk Protection Order) laws to temporarily remove guns from individuals at elevated risk.
