Chronic Pain With Depression Had a Distinct Brain Structure Profile

TL;DR: A 2026 preprint UK Biobank neuroimaging study in medRxiv found that the comorbidity group showed widespread lower cortical volume, subcortical differences, and white matter microstructure alterations, while several alterations appeared unique to the chronic pain-depression comorbidity group. Key Findings Evidence map: a cross-sectional neuroimaging analysis comparing comorbid chronic pain and depression with pain-only, depression-only, …

Childhood and Adult Adversity Linked to Biological Aging Markers

TL;DR: A 2026 BMC Medicine study of UK Biobank adults linked adversity in both childhood and adulthood to higher frailty, older metabolomic age profiles, lower grip strength, and some telomere differences, with the clearest associations in people reporting multiple adverse events. Key Findings Large cohort: The study analyzed up to 153,557 middle-aged and older UK …

Childhood ADHD and Autism Predicted Adult Outcomes, But Rare CNVs Did Not Clarify Risk

TL;DR: A 2026 cohort study in BJPsych Open found that childhood attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) difficulties predicted poorer young-adult outcomes, but rare copy number variants (CNVs), which are deleted or duplicated DNA segments, did not clearly sharpen that prognosis. Key Findings 8,414 young people had CNV data: Researchers analyzed genetic and …

Chemotherapy Neuropathy Review Links Pain to Brain Changes

TL;DR: A 2026 review in Reviews in the Neurosciences argues that chemotherapy-induced peripheral neurotoxicity (CIPN), nerve injury from cancer treatment, can involve central nervous system changes that help explain chronic neuropathic pain and chemotherapy-related cognitive impairment. Key Findings 70-80% during treatment: The review cites chemotherapy-induced peripheral neurotoxicity as affecting about 70-80% of patients during treatment. …

Catatonia Limbic System Alterations Identified in Systematic Review of Neurobiological Evidence

TL;DR: A 2026 systematic review in European Archives of Psychiatry and Clinical Neuroscience argues that catatonia, a syndrome of freezing, mutism, and abnormal movement, may involve underweighted limbic-system circuitry linking emotional regulation with motor shutdown. Key Findings Limbic system has been comparatively underexplored in catatonia neurobiology: Most prior models focused on cortical motor systems and …

Orbitofrontal Atrophy Rating Improved bvFTD Diagnostic Certainty

TL;DR: A 2026 Alzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring study found that orbitofrontal and frontoinsular visual rating scales on MRI helped distinguish possible from probable behavioral variant frontotemporal dementia. Key Findings bvFTD cohort: The study included 93 probable and 15 possible bvFTD patients, plus healthy controls for cross-sectional comparisons. Best regions: Orbitofrontal and …
