TRD MRI Coupling Classified Depression Resistance Above 0.88 AUC

by GLOOM

A 2026 multimodal MRI study found that treatment-resistant depression had lower coordination between brain structure and brain activity than non-treatment-resistant depression in frontal, parietal, motor, and temporal regions. Machine-learning models using those structure-function coupling measures classified treatment-resistant vs. non-treatment-resistant depression with AUC values from 0.886 to 0.950 in the primary atlas analysis.1 Research Highlights TRD …

Catatonia Linked to Lower Left Paracingulate Sulcus Rate (28% vs 53%)

by GLOOM

Photoreal illustration of a brain with the anterior cingulate cortex highlighted, representing transdiagnostic structural markers of catatonia.

A 2026 hospital MRI study found that the left paracingulate sulcus was present in 31 of 109 catatonia patients (28%) vs. 171 of 323 psychiatric controls without catatonia (53%), a left-hemisphere group effect that survived adjustment for age, sex, scanner, brain volume, benzodiazepines, and antipsychotics.1 Research Highlights Left PCS signal: left paracingulate sulcus (PCS) presence …

Personalized TMS for Psychiatric Disorders: Targeting Functional Connectivity (FC) in the Brain (2024 Review)

by GLOOM

Transcranial Magnetic Stimulation (TMS) has emerged as a beacon of hope in the realm of psychiatry, offering a non-invasive alternative for treating psychiatric disorders. The variability in treatment outcomes highlights the necessity for advancements in personalized approaches. A recent paper analyzed the potential of personalized TMS protocols (customized based on individual brain connectivity) may help …

Ketamine Increases Amygdala Volume in Treatment-Resistant Depression (TRD) (2024 MRI Study)

by GLOOM

Depression is a complex mental health condition that significantly affects an individual’s emotional and physical well-being. Recent advances in neuroimaging have provided deeper insights into how major depressive disorder (MDD) alters brain structures, particularly the hippocampus and amygdala, and how treatments like ketamine can potentially reverse these changes. A new study using 3T and 7T …

Cerebellum Activity Predicts Euthymia (Stable Mood) vs. Depression in Bipolar Disorder (2024 Study)

by GLOOM

Bipolar disorder (BD), a complex and multifaceted mental illness, manifests through various mood states including depression, mania/hypomania, and euthymia. Recent advances in neuroimaging, particularly resting-state functional magnetic resonance imaging (fMRI), have shed light on the intricate dynamics of brain activity underlying these mood states. A new study employing dynamic fractional amplitude of low-frequency fluctuations (dfALFF) …

Combo of Neuroimaging, Transcriptome, Epigenetics to Understand Gray Matter Abnormalities in Major Depression (2024 Study)

by GLOOM

Major depressive disorder (MDD) affects millions worldwide, yet its underlying causes remain largely enigmatic. A new study integrated neuroimaging, transcriptomic, and epigenetic data to better understand the genetic underpinnings of MDD. This comprehensive approach revealed a complex interplay between brain structure, gene expression, and DNA methylation, offering new insights into this debilitating condition. Highlights: Integrative …

Detecting Misdiagnosed Bipolar Disorder via MRI Brain Connectivity Analysis (2024 Study)

by GLOOM

Bipolar Disorder (BD) and Major Depressive Disorder (MDD) are two of the most prevalent mood disorders, yet they are often misdiagnosed due to overlapping symptoms. This misdiagnosis can lead to inadequate treatment and worsened patient outcomes. However, recent advances in functional magnetic resonance imaging (fMRI) offer a promising solution to this challenge. By analyzing brain …
