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. …

Cheese3D Six-Camera System Tracked Whole-Mouse-Face 3D Motion at Sub-Millimeter Precision

TL;DR: A 2026 methods paper in Nature Neuroscience introduced Cheese3D, a six-camera system that tracked whole-mouse-face movement in 3D at sub-millimeter precision and used facial dynamics to infer anesthesia depth and neural-state-linked expression. Key Findings Sub-millimeter 3D tracking of the whole mouse face: Cheese3D uses a calibrated 6-camera array to capture motion of ears, eyes, …

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 …

Camel Cerebellum Mapping Found Layer-Specific Glia Patterns

by
Camel Cerebellum Mapping Found Layer-Specific Glia Patterns

TL;DR: A 2026 Scientific Reports study mapped astrocytes, oligodendrocytes, Bergmann glia, and microglia in the camel cerebellum, showing that glial support cells are distributed very differently across cerebellar layers. Key Findings 10 mature camels: Researchers examined cerebellar tissue from 10 mature male camel heads. GFAP was layer-specific: GFAP-positive astrocytes appeared in granular layer and white …

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 …

Abdominal Muscle Contractions Drove Brain Motion and Interstitial Fluid Flow in Awake Mice

by
Abdominal Muscle Contractions Drove Brain Motion and Interstitial Fluid Flow in Awake Mice

TL;DR: A 2026 mouse study in Nature Neuroscience found that abdominal muscle contractions during locomotion drove directed brain motion and helped move interstitial fluid through brain tissue during wakefulness. Key Findings Brain motion was tightly coupled to locomotion, not heartbeat or breathing: Two-photon imaging in awake head-fixed mice showed dorsal cortex shifted relative to skull …

Autistic Children Picked Up Unexpected Second Languages From Screens at 4× the Rate of Peers

by
Autistic Children Picked Up Unexpected Second Languages From Screens at 4× the Rate of Peers

TL;DR: A 2026 study in the Journal of Child Psychology and Psychiatry found unexpected bilingualism in 38.7% of autistic children aged 2-6, about 4.4 times the rate in typically developing peers, with caregivers reporting screen media as the usual source. Key Findings 38.7% of autistic children showed unexpected bilingualism: Using a language absent from the …

Autism EEG Signals Pointed to Opposing Excitation-Inhibition Subtypes

by
Autism EEG Signals Pointed to Opposing Excitation-Inhibition Subtypes

TL;DR: A 2026 preprint electrophysiology study in medRxiv found that the Hurst exponent and gamma oscillations tracked different aspects of excitation-inhibition balance, while human EEG data suggested two autism neurosubtypes with opposing Hurst-gamma profiles. Key Findings Study type: an in-silico, animal-validation, and human EEG study of excitation-inhibition balance in autism. Human EEG dataset: human electroencephalography …

Alzheimer's Capillary Blood Biomarkers Correlated With Cognition

TL;DR: A 2026 study in Nature Communications found that self-administered finger-prick blood tests for phosphorylated tau 217 (p-tau217), an Alzheimer’s tau marker, and glial fibrillary acidic protein (GFAP), an astrocyte-injury marker, correlated with cognition and function in older adults. Key Findings Remote sampling: Participants used capillary finger-prick blood collection rather than standard clinic-based venous blood …
