A major scientific review reveals a deep knowledge gap in how cognition is affected when schizophrenia and personality disorders occur together. Despite the high prevalence and severe outcomes tied to this dual diagnosis, only a small number of rigorous studies have ever examined cognitive functioning in this group.
A new study finds that victims of intimate partner violence who also experience suicidal thoughts or behaviors show distinct and severe injury patterns on medical imaging. These patients were far more likely to present at night in emergency settings and had dramatically higher rates of head, spinal, and deep internal injuries.
A massive multi-year analysis of tens of thousands of dogs reveals that CBD use is becoming increasingly common among aging companion animals. While dogs given CBD initially showed higher aggression, their aggression decreased below average levels with long-term use.
New brain imaging research shows that structural damage in schizophrenia spectrum disorders may begin in specific “epicenter” regions before spreading across connected brain networks. Individuals with the condition showed widespread reductions in structural similarity between key cognitive and emotional brain regions.
Researchers developed an AI tool that detects chronic stress by measuring adrenal gland volume on routine chest CT scans. This biomarker aligns with cortisol levels, stress questionnaires, and future cardiovascular outcomes, offering the first imaging-based method to quantify stress load in the body.
Researchers analyzed the genomes and behavioral profiles of 1,300 golden retrievers and found that several behavioral traits—such as trainability, fear of strangers, and aggression toward other dogs—are shaped by specific genetic variants. Remarkably, a dozen of these same genes also influence emotional and cognitive traits in humans, revealing shared biological roots across species.
New research shows that many people who die by suicide without prior suicidal thoughts or behaviors are not simply “missed cases”—they may have an entirely different underlying risk profile. Genetic analyses of more than 2,700 deaths revealed that these individuals carry fewer genetic risk factors for major psychiatric conditions compared to those with known suicidality.
A new study using DMT as a scientific tool reveals how psychedelics alter the brain’s alpha-wave dynamics and weaken our sense of self. The researchers found that DMT pushes the brain away from its usual “critical” balance between chaos and order, a state believed to be essential for coherent self-awareness over time.
A new study reveals African lions produce two types of roars, overturning long-held assumptions and opening the door to more precise wildlife monitoring. Using machine learning, researchers automatically distinguished between full-throated and newly identified intermediary roars with over 95% accuracy, eliminating much of the human bias in vocal identification.
A new study has identified a specific brain circuit that can push behavior into a compulsive “repeat mode,” forcing mice to continue digging and sniffing even when rewards are available. The circuit links the nucleus accumbens to the hypothalamus and then to the lateral habenula, a region involved in processing negative experiences.
