Teen Trauma Depression: fMRI Predicted Response at 82%

by GLOOM

A 2026 adolescent depression study used resting-state functional magnetic resonance imaging to test whether childhood trauma leaves a measurable network signature in the depressed teen brain. The researchers found disrupted default-mode network hubs in teenagers with major depressive disorder and childhood trauma, and baseline functional-connectome patterns predicted treatment response with 82% accuracy.1 Research Highlights Large …

Prenatal Nighttime Heat Linked to Autism Risk in 294,937-Child Cohort

by GLOOM

MHD featured image for prenatal nighttime heat and autism risk.

A Kaiser Permanente Southern California cohort involving 294,937 children linked extreme prenatal nighttime heat to autism diagnosis by age 5, with stronger associations at the 99th percentile than the 90th percentile.1 Compared with nighttime minimum temperature, daytime maximum temperature did not show the same confirmed whole-pregnancy pattern. Research Highlights Nighttime heat carried the main signal: …

Lobar Brain Bleeds Carried 3.49x Dementia Risk in NLP Stroke-Subtype Study

by GLOOM

MHD featured image for stroke subtypes and dementia risk.

A 2026 Scottish health-system preprint used natural language processing of CT and MRI reports to subtype stroke and found that lobar intracerebral hemorrhage carried a higher dementia risk beyond 6 months, aHR 3.49 vs matched controls.1 The method reduced unspecified stroke coding from 26.1% to 3.4%, making location-specific prognosis easier to see. Research Highlights Lobar …

fMRI Low-Frequency Oscillation Tracked Nicotine Dependence and Arousal

by GLOOM

MHD featured image for systemic low-frequency oscillation fMRI and nicotine arousal.

A 2026 multi-cohort fMRI study found that a signal often treated as physiological noise tracked nicotine dependence, cue-induced craving, abstinence, and stimulant effects.1 During cigarette cue exposure, systemic low-frequency oscillation amplitude correlated with nicotine dependence at r = −0.32, p = .009. Research Highlights Dependence tracked cue-period physiology: In 64 smokers, higher average sLFO amplitude …

GLP-1 Stroke Review Finds Prevention Signal, No Acute Neuroprotection Proof

by GLOOM

MHD featured image for GLP-1 receptor agonists and stroke neuroprotection.

A 2026 review concluded that GLP-1 receptor agonists have plausible stroke biology and modest prevention signals, but current human evidence does not support routine use as acute ischemic stroke neuroprotection.1 The useful clinical split is prevention in cardiometabolic patients vs. acute brain-rescue treatment after stroke onset. Research Highlights Acute neuroprotection is not established: the 2026 …

Lateral Septal PACAP Increased Stress Hormones and Anxiety Behavior

by GLOOM

MHD featured image for lateral septal PACAP signaling and anxiety behavior.

A 2026 rat study found that activating PACAP signaling in the lateral septum amplified stress-hormone release and anxiety-like behavior, while blocking endogenous PACAP receptors produced an anxiolytic pattern.1 The result makes the lateral septum look less like a passive relay and more like a stress-reactivity node in the PACAP pathway. Research Highlights Stress hormones rose: …

Trichostatin A for Alzheimer’s: 8 Core Genes, Unstable Binding

by GLOOM

MHD featured image for Trichostatin A and Alzheimer's disease gene networks.

A 2026 PLOS One computational study linked Trichostatin A to 949 predicted targets and 8 machine-learning-selected Alzheimer’s disease core genes, but 100 ns molecular dynamics simulations suggested the compound did not stably bind those candidate proteins.1 That makes the result more useful as an epigenetic network hypothesis than as evidence for a near-term Alzheimer’s drug. …
