A context-sensitive road map for #MentalHealth system scale-up indicates that governance, supervision, referral pathways, monitoring, and local adaptation are necessary for sustainable implementation. https://t.co/lMztUNh1jH

US #MentalHealth and #SubstanceUseDisorder expenditures totaled $174 billion in 2021-2023, or 7.0% of all medical spending, with ambulatory services accounting for the largest share. https://t.co/40hYIIOUfe

Maternal #PlacentalGrowthFactor trajectories diverged in the third trimester in pregnancies where children were later diagnosed with #ADHD, while endothelin-1 did not differ.

💬 Viewpoint: A special collection in #Psychiatry highlights early-career investigators studying clinical equity, structural #MRI and machine learning, ultraprocessed foods and depression, and placental growth factor trajectories.

Structural #MRI with machine learning estimated individual delay discounting in college-aged participants, with white matter volumes showing stronger performance than gray matter volumes.

In patients with #Depression and high #UltraprocessedFoods intake, a low-ultraprocessed-food diet was feasible and acceptable, and depressive and anxiety symptoms were lower during the intervention period vs a regular diet.

💬 Viewpoint: In #Psychiatry, care for #Deaf and hard-of-hearing patients requires clinical competency because hearing loss, signed language, and social bluffing can complicate the Mental Status Examination and affect diagnosis.

From 2014 to 2024, #Psychiatry and #Psychology lobbying spending rose 29%, with notable increases among hospitals and nursing homes, while overall health professional lobbying declined. https://t.co/7dQ9JemCh5

📝 Narrative Review: Low-dose #Lithium exposure is linked to neuroprotective effects, reduced #Dementia risk, and cognitive stabilization in mild cognitive impairment, supporting further clinical evaluation. https://t.co/UrGDyAuX8a

[JAMA Psychiatry @JAMAPsych]

A pluralistic model of #Schizophrenia recognizes multiple neurochemical and cellular mechanisms, not just dopaminergic dysregulation, to help explain symptom heterogeneity and guide biomarker-informed, mechanism-based treatment development. https://t.co/T69ROMHV8V

[JAMA Psychiatry @JAMAPsych]

Many studies using #Neurodivergent or #Neurodiverse terminology identified participants through self-report or self-identification, and some did not specify any diagnosis. Precise diagnostic descriptors may improve clinical research and practice.

📝 Viewpoint: #Cannabis commercialization is a modifiable public health exposure shaped by policies on access, potency, labeling, and marketing. Regulating these features may reduce psychiatric risk beyond legalization status alone. 10.1001/jamapsychiatry.2026.2869

[JAMA Psychiatry @JAMAPsych]

In a matched study of more than 1 million patients, hospitalization for infection raised 2-year risks of #psychiatric and #neurologic disorders, especially cognitive deficits and encephalitis, with the greatest impact among adults. https://t.co/lBlPuA42Ez

[JAMA Psychiatry @JAMAPsych]

📝 Viewpoint: High-dose #psychedelic #clinicaltrials remain poorly masked, which limits isolation of pharmacological effects from expectancy effects.

More aggressive active comparators and reduced disclosure may strengthen causal inference.
