CONCLUSIONS: The legal doctrine of settled insanity does not map well onto clinical reality and complicates the intersection of intoxication and mental illness by prompting insoluble questions about the etiology of mental illness. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

CONCLUSIONS: These findings support the potential for TAAR1 agonists as novel treatments for hyperactivity and risky decision-making in BD, and suggest an inverted U-shaped relationship between dopamine tone and decision-making optimization.

CONCLUSION: In this sample of older adults with self-reported mental health condition, about one-third had at least one annual preventive dental visit during the observation period. Receiving care from faculty members was significantly associated with increased odds of attending annual preventive dental visits.

It is hypothesised that structural brain abnormalities in individuals with schizophrenia are associated with aggressive behaviour, but this has not been tested directly. We pooled magnetic resonance imaging and clinical data from 2095 patients and 2861 healthy control subjects across 20 sites of the ENIGMA-Schizophrenia Working Group. Using normative modelling, we quantified individual-level deviations from controls (z-scores) for global and regional grey matter volume and white matter...

CONCLUSION: In all, 30% of patients with UCPPS demonstrated improvement in pain and/or urinary symptoms over 3 years. Baseline factors associated with improvement may represent markers of a milder or localised phenotype and/or treatment effects.

Cognitive symptoms are common in Parkinson's disease (PD) and have debilitating effects on quality of life and disease trajectory; however, the underlying brain mechanisms remain poorly understood. To address this gap, we investigated the relationship between functional connectivity and cognition at multiple time points using longitudinal functional MRI (fMRI) and cognitive assessments from the Parkinson's Progression Marker Initiative (PPMI). We calculated resting-state functional connectivity...

The persistence of HIV latent reservoir is the major challenge to HIV cure because latent viruses serve as sources for viral rebound upon ART cessation. Mechanisms regulating viral persistence are not well understood; thus, there is a compelling need for research focusing on addressing the knowledge gap related to HIV persistence. The present study focuses on the effect of extracellular condensates (ECs) on latent HIV/SIV reactivation in the brain in the context of HIV infection using the...

Cognitive deficits are common in primates, particularly in memory and emotional processes. Rhesus monkey (Macaca mulatta), widely used in cognitive and behavioral research, are central to memory studies. The relationship between recognition memory performance and pupillary dynamics in rhesus monkeys remains underexplored. This study investigated pupil dynamics during recognition memory tasks and their physiological correlates in five sexually mature male rhesus monkeys. We measured pupil...

CONCLUSIONS: Baseline cognitive functions, including executive function, did not influence reduction in depressive symptoms during brief psychotherapies. Brief psychotherapies may improve aspects of executive function such as decision-making related to reward.

Impaired decision-making is often seen in people with bipolar disorder (BD), even those undergoing treatment. Targeted therapeutics are therefore needed. People with BD report that cannabis use (CU) attenuates such cognitive and behavioral symptoms. We hypothesized that 1) people with BD who do not use cannabis would exhibit poor decision-making and functional capacity relative to healthy comparison (HC) participants and 2) CU in people with BD would be associated with decision-making and...

Post-acute sequelae of COVID-19 (Long COVID) includes physical and cognitive symptoms that can last long after acute infection. Links between lung pathophysiology and cognitive dysfunction in Long COVID remain largely unexplored. Long COVID participants were recruited from a post-COVID-19 clinic. Participants completed Patient-Reported Outcomes Measurement Information System (PROMIS) symptom questionnaires for Sleep Disturbance, Anxiety, Depression, and Cognitive Function, the National Institute...

Attention-deficit/hyperactivity disorder and anxiety disorders are highly prevalent in youth and are characterized by substantial heterogeneity and frequent co-occurrence. This transdiagnostic complexity challenges conventional diagnostic frameworks that rely on symptom-based categories, which often obscure underlying dimensional and neurobiological mechanisms and offer limited neurobiological specificity. To address these issues, we developed a deep learning-based brain-behavior modeling...

Obsessive-compulsive disorder (OCD) and chronic tic disorders (CTD) are highly heritable. Recent progress in OCD genomics has highlighted small-effect common alleles. Rare mutations have previously been found to carry large risks for OCD and CTD but only four high-confidence (hc) genes have been identified. We analyzed whole-exome sequencing data from 3,964 individuals with OCD, CTD, or both, including 2,418 trios. We find an excess in cases of de novo and rare protein-damaging mutations and...

Although adult Huntington's disease (HD) studies have significantly advanced our understanding of the course of degeneration, they may underrepresent critical neurodevelopmental aspects of the disease. Significant gaps remain in understanding how mutant huntingtin affects early neurodevelopment, its long-term impact, as well as potential implications for treatment outcomes. The Childhood to Adult Neurodevelopment in Gene-Expanded Huntington's Disease (ChANGE-HD; NCT01951588) study aims to...

CONCLUSIONS AND RELEVANCE: In this EHR-based cohort study, OSA appeared to be an independent risk factor for the later development of PD and could be modified by early treatment with CPAP. Effective screening measures and protocols for consistent adherence to CPAP may have large impacts on brain health.
