Monthly Lecanemab Maintained Alzheimer’s Blood Biomarker Changes After 18 Months

June 18, 2026 by BrainASAP

TL;DR: A 2026 study in Alzheimer’s & Dementia: Translational Research & Clinical Interventions used lecanemab pharmacokinetic/pharmacodynamic modeling in early Alzheimer’s disease and found that blood biomarkers worsened after treatment stopped, while monthly maintenance dosing after 18 months was predicted to preserve most p-tau181 and GFAP, an astrocyte-inflammation protein. Key Findings Three plasma biomarkers improved: Lecanemab …

Misophonia and Hyperacusis Showed Different fMRI Sound-Processing Patterns

June 18, 2026 by BrainASAP

TL;DR: A 2026 study in Cognitive, Affective, & Behavioral Neuroscience used task-based functional MRI (fMRI), a brain-scan method that tracks blood-oxygen changes during a task, to show that misophonia and hyperacusis had partly different brain connectivity patterns during unpleasant sound processing. Key Findings 91 young adults were analyzed after 1 participant was excluded for excessive …

Smartphone Migraine Study Captured Daily Brain Fog and Symptom Burden

June 18, 2026 by BrainASAP

TL;DR: A 2026 medRxiv preprint enrolled 177 adults with migraine in a 30-day smartphone study and found that daily cognition and symptom check-ins were feasible, with 3,688 completed assessments and higher baseline burden in chronic migraine. Key Findings Migraine cohort: The MIND study followed 177 adults with migraine using once-daily smartphone surveys and brief mobile …

MeCP2 Overexpression Disrupted Neural Progenitor Cells More Than Mature Neurons

June 18, 2026 by BrainASAP

TL;DR: A 2026 Nature Communications study found that extra MeCP2, the dosage-sensitive protein linked to Rett syndrome and MECP2 duplication syndrome, disrupted neural progenitor cells far more than mature neurons by activating developmental genes too early. Key Findings Cell timing mattered: MeCP2 overexpression caused broad transcriptional changes in neural progenitor cells, but only modest changes …

Ketogenic Diet Review Reported Glioblastoma Survival Signals Without Phase III Proof

June 18, 2026 by BrainASAP

TL;DR: A 2026 systematic review and meta-analysis in Neurological Sciences found that ketogenic diet (KD), a very-low-carbohydrate diet designed to raise ketone fuel use, looked feasible and generally safe as an add-on strategy in glioblastoma (GBM), but the survival signal still needs phase III randomized proof. Key Findings The review included 41 human studies of …

Introductory Psychology Textbooks Still Repeated Myths and Bias

June 18, 2026 by BrainASAP

TL;DR: A 2025 study in The Journal of General Psychology found that introductory psychology textbooks showed modest improvement from 2018 to 2023, but several classic myths and contested topics were still presented in biased or oversimplified ways. Key Findings Researchers rated coverage of 11 textbook topics that psychology professors had flagged as commonly distorted or …

Il6 Deficiency Worsened Parkinson’s Mouse Damage by Sex

June 18, 2026 by BrainASAP

TL;DR: A 2026 study in Genes & Diseases found that Il6 deficiency, meaning loss of the gene for interleukin-6, worsened Parkinson’s-like motor and dopamine-system injury in mice. Key Findings Il6 knockout worsened movement: Mice lacking Il6 performed worse after MPTP, a toxin commonly used to model Parkinson’s-like dopamine injury. Female knockout mice showed earlier damage: …

Hebbian Learning Trapped Activity in Network Spreading Model

June 17, 2026 by BrainASAP

TL;DR: A network model in Communications Physics (2026) found that Hebbian learning, the familiar “fire together, wire together” rule, trapped activity in old routes, while anti-Hebbian weakening helped activity reach new areas. Key Findings Positive reinforcement trapped activity: when successful activation made the same link more likely to be used again, activity tended to circle …

HCN1 Triggered Neuronal Pacemaker Depolarization Faster Than HCN2 or HCN4

June 17, 2026 by BrainASAP

TL;DR: A 2026 Nature Communications study found that HCN1, an ion channel that helps neurons start rhythmic electrical firing, was fast enough to act as the trigger for neuronal pacemaker depolarization, while HCN2 and HCN4 mainly appeared too slow to drive each action-potential cycle. Key Findings HCN1 was the fast channel: In slow action-potential clamp …

Farsi-Speaking Refugees in Germany Had High Emotional Distress Risk

June 17, 2026 by BrainASAP

TL;DR: A 2026 cross-sectional study in Disaster Medicine and Public Health Preparedness found that 159 of 230 Farsi-speaking refugees in German refugee camps screened at high risk for depression, anxiety, and PTSD symptoms, while resilience, psychological flexibility, meaning in life, and social support also predicted posttraumatic growth. Key Findings High distress was common: 159 of …
