Depression Severity Linked to Brain Energy Landscape State-Transition Entrapment

TL;DR: A 2026 study in Nature Communications used resting-state functional MRI (fMRI) to link major depressive disorder to more frequent but shorter visits to a salience-dominated brain state. Key Findings Resting-state fMRI compared depression with controls: the analysis included 38 adults with major depressive disorder and 38 healthy controls. Structural-connectivity modeling used a smaller subset: …

CYP2C19 Metaboliser Status Linked to DNA Methylation Patterns

TL;DR: A 2026 methylome-wide study in Clinical Epigenetics found that genetically inferred CYP2C19 metaboliser status, a pharmacogenomic marker relevant to antidepressant handling, was associated with DNA methylation patterns in a large Scottish cohort. Key Findings 18,396-person discovery cohort: Generation Scotland supplied the main genetic and DNA methylation analysis for CYP2C19 metaboliser status. 48 quadratic CpG …

Coherent Breathing Improved Recovery Markers in Trained Athletes

TL;DR: A 2026 randomized study in The Journal of Strength and Conditioning Research found that coherent breathing, a slow 6-breaths-per-minute breathing routine, improved several recovery markers in highly trained 400-meter athletes under repeated race stress without improving race times. Key Findings 22 trained athletes: Researchers randomized 11 athletes to usual recovery and 11 athletes to …

Cerebellar Gray Matter Was Lower in Bipolar Than Unipolar Depression

TL;DR: A 2026 study in BMC Psychiatry found that structural MRI of the cerebellum separated first-episode bipolar depression from unipolar depression with 76.3% exploratory model accuracy, mainly because several cerebellar gray-matter regions were smaller in bipolar depression. Key Findings MRI cohort included three groups: Researchers analyzed structural MRI from 42 bipolar depression patients, 48 unipolar …

Catatonia Linked to Lower Left Paracingulate Sulcus Presence on MRI

TL;DR: A 2026 MRI preprint on medRxiv found that patients with catatonia were less likely to have a left paracingulate sulcus (PCS), a stable anterior cingulate cortex fold, than psychiatric patients without catatonia. Key Findings 523 MRI scans: Researchers compared 109 patients with catatonia, 323 psychiatric patients without catatonia, and 91 healthy controls. Left PCS …

Cannabis Use Frequency and THC Exposure Did Not Change Brief-Abstinence Pain Sensitivity

TL;DR: A 2026 study in Psychopharmacology found that healthy adults who used cannabis frequently had higher circulating THC markers after at least 12 hours of verified abstinence, but their cold-pressor pain threshold, pain tolerance, and pain ratings did not differ from occasional users. Key Findings 75 cannabis users were tested: the sample included 38 occasional …
