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 …

Major Upper-Extremity Amputation Raised Mental Health Odds

by GLOOM

Major upper-extremity amputation was linked to substantially higher odds of new mental-health diagnosis, antidepressant initiation, and psychotherapy claims than minor upper-extremity amputation in a matched national database study. The clearest clinical implication is early mental-health screening after major limb loss, not waiting for distress to surface months later.1 Research Highlights 2,452 matched patients were analyzed: …

Treatment-Resistant Depression in Pakistan: 34% TRD, 86% Polypharmacy

MHD featured image for treatment-resistant depression, polypharmacy, and CYP2C19 findings in Pakistan.

A 2026 DIVERGE analysis of 3,677 antidepressant-exposed patients with major depressive disorder in Pakistan classified 34% as treatment resistant, while 86% received psychotropic polypharmacy and only 6% received psychotherapy.1 The CYP2C19 signal is real enough to study prospectively, but the main treatment-system finding is medication stacking in a setting where psychological care was rare. Research …

77-Drug Blood Screen Found Benzodiazepines in 37.9% of Detections

by GLOOM

MHD featured image for neuropsychiatric drug blood screening and benzodiazepine detections.

A 2026 clinical-lab study tested a 77-drug liquid chromatography-tandem mass spectrometry serum screen in 1,021 patients and found that benzodiazepines accounted for 37.9% of all detections, ahead of antidepressants and antipsychotics.1 Emergency-department cases were a small slice of the sample, but they were positive more often than outpatients: 85.2% vs. 59.5%. Research Highlights Benzodiazepines dominated …

Fibromyalgia Costs in Saudi Arabia: $2,560 Annual Direct Medical Cost

by GLOOM

MHD featured image for fibromyalgia healthcare costs in Saudi Arabia.

A 2026 Saudi tertiary-hospital study estimated that adults treated for fibromyalgia — chronic widespread pain with fatigue, sleep disruption, cognitive symptoms, and overlapping mood or medical problems — generated SAR 9,601.2 (USD 2,560.3) in annual direct medical costs per patient, with specialist visits and diagnostic procedures accounting for 96.3% of recorded spending.1 Research Highlights Annual …

PGx Testing Found Actionable Genotypes in 30% of Veterans

by GLOOM

MHD featured image for pharmacogenomic testing in veteran depression and antidepressant polypharmacy.

A 12-week randomized pilot trial in 60 Veterans with depression and psychiatric polypharmacy found that 30% had an actionable antidepressant gene-drug interaction, but immediate access to pharmacogenomic results did not clearly change prescribing or Patient Health Questionnaire-9 depression scores compared with delayed access.1 Research Highlights Actionable PGx results were common: 18 of 60 Veterans, or …

SSRI Pharmacogenomic Testing: CYP2D6, CYP2C19, Remission

by GLOOM

A 2026 methylome-wide association study by Shen et al. found 48 CpG methylation sites tied to the quadratic CYP2C19 metabolizer-status term in 18,396 Generation Scotland participants, with 19 sites showing non-linear patterns and targeted replication in 1,238 older adults.1 That supports CYP2C19 as real biology beneath SSRI pharmacogenomics, but it does not prove universal antidepressant …
