Lisdexamfetamine Overdose Caused Delayed Severe Stress Cardiomyopathy in a Teen Case

TL;DR: A 2026 Critical Care Explorations paper described a 17-year-old girl whose intentional lisdexamfetamine overdose was followed by delayed severe heart failure, with left ventricular ejection fraction falling below 20% before recovery over months. Key Findings Delayed cardiac collapse: The patient first appeared stable after treatment, then worsened again about 24 hours after ingestion. Severe …

Ketogenic Diet Review Reported Glioblastoma Survival Signals Without Phase III Proof

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

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

by
Il6 Deficiency Worsened Parkinson's Mouse Damage by Sex

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: …

Iceland Psychiatric Diagnoses and Medication Fills Were Common After Age 40

TL;DR: A 2026 nationwide study in PLOS One found that adults age 40 and older in Iceland often had psychiatric diagnoses and psychotropic medication fills, with 20.8% receiving a diagnosis in the prior year and 34.2% filling at least one psychotropic prescription. Key Findings Nationwide cohort: Researchers analyzed registry data from 80,733 Icelanders age 40 …

Hebbian Learning Trapped Activity in Network Spreading Model

by
Hebbian Learning Trapped Activity in Network Spreading Model

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

by
HCN1 Triggered Neuronal Pacemaker Depolarization Faster Than HCN2 or HCN4

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 …

Glucose Signaling via ACLY Shaped Myelin-Forming Cell Development

by
Glucose Signaling via ACLY Shaped Myelin-Forming Cell Development

TL;DR: A 2026 mouse study in Nature Neuroscience found that glucose signaling through ATP-citrate lyase (ACLY), an enzyme that links sugar metabolism to gene regulation, helped oligodendrocyte progenitor cells multiply before they matured into myelin-forming cells. Key Findings Glucose mapped onto cell state: Developing mouse-brain regions with higher glucose had more proliferating oligodendrocyte progenitor cells, …

GLP-1 Weight Loss Drew More Stigma Through Shortcut Beliefs

TL;DR: A 2026 study in Stigma and Health found that women who lost 15% of body weight with GLP-1 receptor agonists, medications such as semaglutide that mimic a metabolic hormone involved in appetite and glucose signaling, were judged more harshly than women who lost the same amount through diet and exercise. Key Findings Medication-assisted loss …

Community Forensic Mental Health Services Still Vary Across England

TL;DR: A 2026 service-mapping study in BJPsych Bulletin found that community forensic mental health services (CFMHS), specialist teams for people with mental disorder and serious risk histories, still vary widely across England in structure, referral access, staffing, and crisis coverage. Key Findings 32 services responded: Researchers received data from 32 CFMHS after sending Freedom of …
