Parent-Implemented Autism Intervention Helped Chinese Preschoolers

TL;DR: A 2026 randomized trial in Molecular Autism found that a culturally adapted parent-implemented social communication program was linked to language, social-functioning, parent self-efficacy, and stress gains in Chinese-speaking autistic preschoolers, with no consistent advantage for therapist-led online groups over self-study across most outcomes. Key Findings Chinese preschoolers randomized: 112 autistic children aged 24-60 months …

Poor Sleep Tracked Faster Biological Aging, but Causation Was Mixed

TL;DR: A 2026 preprint in medRxiv found that poor sleep tracked faster biological aging across more than 64,000 adults, but twin and genetic analyses left the causal claim mixed rather than settled. Key Findings 64,000+ adults: Researchers tested sleep and aging biomarkers across five independent datasets spanning young, middle, and late adulthood. Poorer sleep quality: …

Esketamine Stellate Ganglion Block Reduced Postoperative Sleep Disturbance

by
Esketamine Stellate Ganglion Block Reduced Postoperative Sleep Disturbance

TL;DR: A 2026 randomized trial in BMC Anesthesiology found that adding an esketamine-adjuvanted stellate ganglion block to intraoperative esketamine plus dexmedetomidine reduced early postoperative sleep disturbance after gynecological laparoscopic surgery. Key Findings Sleep disturbance fell on day 1: Postoperative sleep disturbance affected 62.9% of patients in the stellate ganglion block group versus 83.2% in controls. …

Autistic Children With Speech Delay Showed Reversed Auditory Bias

by
Autistic Children With Speech Delay Showed Reversed Auditory Bias

TL;DR: A 2026 study in Autism Research found that autistic children with early speech delay needed longer sound gaps to detect timing changes, but detected smaller pitch-frequency changes than typically developing peers. Key Findings 21 autistic children were compared with 23 typically developing children: The autism group had early language delay and early autistic manifestations, …

Stroke Thrombectomy Technique Preference Did Not Predict First-Pass Reperfusion

by
Stroke Thrombectomy Technique Preference Did Not Predict First-Pass Reperfusion

TL;DR: A 2026 medRxiv preprint found that stroke thrombectomy operators often had a preferred device technique, but that preference did not reliably match the technique with the highest first-pass reperfusion rate. Key Findings Stroke thrombectomy cohort: The single-center analysis included 1,405 acute ischemic stroke patients treated with mechanical thrombectomy from 2019 through 2024. 75% had …

Perinatal EEG Delta and Alpha Power Tracked Depression and Anxiety

by
Perinatal EEG Delta and Alpha Power Tracked Depression and Anxiety

TL;DR: Portable electroencephalography (EEG) recordings tracked perinatal anxiety most consistently in a preliminary medRxiv preprint, with delta power carrying the clearest longitudinal marker and alpha power appearing in visit-specific anxiety analyses. Key Findings First-trimester marker: Relative delta power before 16 gestational weeks was associated with third-trimester PHQ-9 depression and GAD-7 anxiety scores. Delta-anxiety link: Across …

Cerebellar Hypermetabolism Impaired Fronto-Cerebellar Connectivity in Alcohol Use Disorder

by
Cerebellar Hypermetabolism Impaired Fronto-Cerebellar Connectivity in Alcohol Use Disorder

TL;DR: A 2026 study in Translational Psychiatry combined positron emission tomography (PET) and functional MRI (fMRI) in alcohol use disorder and linked cerebellar hypermetabolism to disrupted fronto-cerebellar connectivity and poorer inhibition performance. Key Findings AUD-control sample: Researchers compared 27 people with severe alcohol use disorder (AUD) and 25 healthy controls. Multimodal imaging used: The study …

Depression Reduced Alpha-Beta Reward Signaling in Movement Disorder Patients

by
Depression Reduced Alpha-Beta Reward Signaling in Movement Disorder Patients

TL;DR: A 2026 study in eNeuro used intracranial electroencephalography (EEG), a recording method for brain electrical activity, during deep brain stimulation surgery and found that Parkinson’s disease and essential tremor patients with elevated depression symptoms had weaker corticostriatal alpha-beta reward signaling. Key Findings 30 DBS patients participated: The sample included 14 Parkinson’s disease patients and …

Fisetin Plus Training Improved Maresin-1 and HOMA-IR in Obesity Trial

by
Fisetin Plus Training Improved Maresin-1 and HOMA-IR in Obesity Trial

TL;DR: A 2026 randomized trial in Journal of the International Society of Sports Nutrition found that 12 weeks of combined interval resistance and aerobic training increased Maresin-1, an inflammation-resolving lipid mediator, in men with obesity, with the largest insulin-resistance improvement when training was paired with 200 mg/day fisetin. Key Findings 44 men completed the trial: …

Alzheimer Plasma Proteomics Favored Continuous Molecular Axes

by
Alzheimer Plasma Proteomics Favored Continuous Molecular Axes

TL;DR: A 2026 preprint in medRxiv analyzed plasma proteomics in Alzheimer’s disease and mild cognitive impairment and found that four continuous molecular axes described the data better than hard subtype labels. Key Findings 5,895-person AD/MCI sample: The discovery analysis used one record per participant from the Global Neurodegeneration Proteomics Consortium. 81.5% module-space variance: Four continuous …
