Early Antidepressants Linked to Bipolar Impulsivity During Euthymia

by GLOOM

MHD featured image for early antidepressant exposure and impulsivity in bipolar disorder.

A 124-person study of euthymic bipolar disorder found that patients with early systematic antidepressant treatment history had higher negative affect, attentional impulsivity, non-planning impulsivity, and total BIS-11A impulsivity scores than matched patients without that history.1 The association is clinically cautionary, but the cross-sectional design cannot separate antidepressant effects from delayed bipolar diagnosis or more severe …

COPE-A Reduced Youth PTSD in Substance-Use Trial

MHD featured image for youth PTSD, substance use, COPE-A, and symptom sequencing during therapy.

A 2026 randomized youth trial found that integrated exposure-based treatment reduced posttraumatic stress disorder symptoms more than supportive counseling, while substance-use changes were smaller and showed no clear treatment-specific advantage. Research Highlights COPE-A reduced PTSD more: youth receiving Concurrent Treatment of PTSD and Substance Use Disorders Using Prolonged Exposure – Adolescent version had a 17.00-point …

Catatonia Brain Circuits: Limbic System Review

by GLOOM

MHD featured image for catatonia, limbic-system brain circuits, and psychomotor shutdown.

A 2026 systematic review argues that catatonia should be read as a limbic-cortical circuit syndrome, with motor shutdown tied to brain systems for threat, salience, motivation, and emotional regulation. Research Highlights 20 studies met criteria: the 2026 review screened 1,792 records, assessed 54 full texts, and included 20 articles: 13 observational studies and 7 case …

Child Violence in South Africa: 91% Exposed by Age 8

by GLOOM

MHD featured image for child violence exposure and mental health in a South African birth cohort.

Violence exposure was nearly universal by age 8 in a South African birth cohort: 91.1% of children had experienced at least 1 violence type, and 53.6% had experienced more than 1. Recent violence exposure at age 8 was consistently tied to mental-health problems, while earlier exposure at age 4.5 showed weaker longitudinal prediction than same-age …

Rats Beat Humans in 2-Second Temporal Error Monitoring Study

by GLOOM

MHD featured image for temporal error monitoring and timing metacognition.

A 2026 iScience study found that both humans and rats could report whether their own 2-second timing responses were small-error or large-error trials, but rats were more accurate on test choices: human accuracy was 55%-57%, rat accuracy was 65%-67%, and the species gap remained significant before task-variable matching.1 Research Highlights Both species monitored timing errors: …

Syntaxin-6 Knockout Rescued Motor and Frailty Signs in Tauopathy Mice

by GLOOM

MHD featured image for syntaxin-6 knockout and tauopathy motor rescue in mice.

A 2026 humanized P301S tauopathy mouse study found that syntaxin-6 knockout partly rescued early motor impairment from months 1 to 4, protected gait at 5.5 months, reduced frailty (p = 0.0052), and reduced superficial-cortex neurodegeneration at 3 months (p = 0.0055).1 The finding strengthens syntaxin-6 as a tauopathy modifier, but it is still mouse genetics, …

Dream Content Tracks Personality, Sleep Quality, and Stress

by GLOOM

Dreams transform waking life rather than replaying it directly. In a 2026 Communications Psychology study of 3,366 reports, dreams were more visual, spatial, social, and bizarre than waking reports, while attitude toward dreaming, mind-wandering tendency, sleep quality, and COVID lockdown stress each left measurable fingerprints on dream content.1 Research Highlights Dreams were not random word …
