Brain Structure Differences in Children with ADHD Discovered

Researchers tested a new MRI correction method, called the traveling-subject (TS) approach, to resolve inconsistencies in ADHD brain imaging results. By scanning the same healthy subjects across multiple MRI machines, they identified and corrected for measurement biases, producing more reliable data.

Astrocyte Disruption Tied to Depression After Childhood Stress

Researchers have shown that astrocytes in the lateral hypothalamus play a pivotal role in how stress shapes behavior, particularly after early-life adversity. In mice, stress led to smaller, less branched astrocytes and abnormal orexin neuron activity, with sex-specific patterns in activity levels.

Sex Shapes the Course of Bipolar Disorder and Schizophrenia

A large multicenter study has revealed that sex influences the course and characteristics of schizophrenia and bipolar disorder. Women with schizophrenia tended to begin treatment later, while men with schizophrenia had the highest rates of substance use.

Chronic Stress Sends Immune Cells to Brain, Driving Depression

A new study shows that chronic stress causes immune cells called neutrophils to leave bone marrow in the skull and collect in the brain’s protective membranes, where they contribute to depressive symptoms. In mice, blocking an immune “alarm” pathway reduced these cells and improved mood-related behaviors.

This shows a brain with two paths leading to it.

Depression Disrupts Learning to Avoid Unpleasant Events

Depression specifically impairs the ability to learn how to actively avoid unpleasant events, though it does not affect avoidance behavior once learned. Researchers tested 465 participants across a range of depressive symptoms in a task adapted from rodent research, involving sounds and visual cues.

Hormonal Contraceptives Influence Memory of Emotional Events

A new study reveals that hormonal contraceptives may shape both emotional responses and memory processing in women. Compared with naturally cycling women, users of hormonal birth control had stronger emotional reactions and remembered fewer details of negative events when using regulation strategies like distancing or reinterpretation.

Brain Cells Behind Depression Identified

Researchers analyzing post-mortem brain tissue found two cell types altered in people with depression: excitatory neurons that regulate mood and stress, and microglia that manage inflammation. The findings highlight how depression is tied to measurable brain changes, not just emotional symptoms.

The Midlife “Unhappiness Hump” Has Vanished, But at a Cost

A new large-scale study finds that the long-observed “unhappiness hump,” where mental distress peaked in midlife, has disappeared. Instead, younger people now report the highest levels of anxiety, depression, and stress, with ill-being declining across the lifespan.

Cannabis Linked to Reduced Insomnia and Anxiety

A new study suggests cannabis-based medical products may help people with insomnia sleep better over the long term. Across 124 patients followed for up to 18 months, participants consistently reported improved sleep quality, less anxiety and depression, and a better overall quality of life.

Brain Map Reveals How Stress and Social Control Interconnect

A new study has identified a key brain hub in the medial prefrontal cortex that regulates stress responses and social behavior, offering critical insights into psychiatric conditions. Using advanced imaging and AI mapping in mice, scientists charted how these regions integrate sensory and bodily signals to control emotional stability.

Big Five No More? New Study Uncovers Hidden Personality Traits

For 40 years, the Big Five personality model has dominated psychology, but new research suggests it may be incomplete. Using taxonomic graph analysis, researchers mapped personality from the ground up, uncovering new meta-traits and traits not captured by the Big Five.

High-THC Cannabis Linked to Psychosis and Addiction

A systematic review of nearly 100 studies found that high-THC cannabis products are linked to negative mental health outcomes, particularly psychosis, schizophrenia, and cannabis use disorder. While some therapeutic research hinted at benefits for anxiety and depression, results were inconsistent and often showed potential harm.
