Participants were born before 1951 and KPNC members for 4+ years during 1997-2010. Embedded subsamples included sociodemographic and genetic data. Statin initiators were matched at first prescription (\"baseline\") with up to 5 \"noninitiators\" based on age and low-density lipoprotein cholesterol (LDL-C). Participants with extreme propensity scores were excluded. The outcome was time to incident AD/ADRD diagnosis, censoring, or the administrative end of study (December 31, 2020). Cox proportional hazard models were used to estimate hazard ratios for statin initiation on AD/ADRD incidence.

Cannon and Spanish physician Gregorio Marañón engaged in a sustained transatlantic correspondence that shed light on emerging ideas about the physiologic basis of emotion. Drawing on letters preserved at Harvard's Countway Library of Medicine and the Fundación Ortega-Marañón in Madrid, we examine how their dialogue bridged experimental physiology and clinical neuroendocrinology during a formative era in modern neuroscience. Cannon, widely known for introducing the concepts of \"homeostasis\" and the \"fight-or-flight\" response, saw in Marañón's clinical observations a compelling complement to his laboratory findings. In particular, Cannon repeatedly cited Marañón's work on the emotional effects of adrenaline, which distinguished between purely physiologic visceral reactions without subjective emotion (\"cold emotion\") and full subjective emotional states (\"hot emotion\"). This nuanced differentiation anticipated later cognitive and constructivist theories of emotion. Their exchange helped shape foundational concepts in affective and autonomic neuroscience by linking internal affective states to neuroendocrine mechanisms and observable bodily responses. These ideas would later cohere in Cannon's The Wisdom of the Body (1932), where traces of their correspondence are evident. Beyond their scientific importance, the Cannon-Marañón letters offer a rare window into the international and interdisciplinary networks that shaped biomedical thought in the early 20th century. It also reflects broader commitments because both men had a relevant political involvement. By recovering this epistolary exchange, we shed light on an overlooked chapter in the history of neuroscience and the enduring value of scientific dialogue.","PeriodicalId":19256,"journal":{"name":"Neurology","volume":"53 1","pages":"e213952"},"PeriodicalIF":9.9,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144684166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vessel wall MRI (VWMRI) offers the potential to identify culprit vNSPs, yet prospective studies in ESUS populations are lacking. This study aimed to assess the role of vNSPs in single-territory ESUS and to evaluate the utility of intracranial VWMRI in the diagnostic workup.</p><p><strong>Methods: </strong>Consecutive patients admitted to the Stroke Unit of the IRCCS Mondino Foundation (Pavia, Italy) with a confirmed ESUS diagnosis after a complete etiologic workup were prospectively enrolled in the study. Patients with multiterritorial ischemic lesions, complicated aortic arch atherosclerosis, or a probable patent foramen ovale-associated stroke were excluded. Intracranial VWMRI at 3-T was performed within 1 month of the index event. Atherosclerotic lesions were considered culprit if demonstrating postcontrast enhancement on T1-weighted images and a location consistent with ischemic lesions' distribution. Quantitative radiologic features of vNSPs were also analyzed.</p><p><strong>Results: </strong>A total of 80 patients (mean age 65.6 years, 34 [42.5%] women) were included. VWMRI identified a potentially culprit vNSP in 23 of 80 patients (28.8%, 95% CI 20-39.5).

The aim of this study was to evaluate the incidence and characteristics of postictal central apnea (PICA) in focal seizures. The secondary aim was to analyze morphometric features of the amygdala and other subcortical structures involved in autonomic control.METHODSWe prospectively enrolled consecutive patients admitted to the Epilepsy Monitoring Unit at Modena Academic Hospital (Italy) from April 2020 to December 2023. Inclusion criteria were as follows: (1) age older than 13 years; (2) at least 1 focal-onset seizure recorded during long-term video-EEG monitoring (LTVEM) with cardiorespiratory polygraphy. For each seizure, the presence of ictal central apnea (ICA) and/or PICA and its features were evaluated. Amygdala, hippocampus, thalamus, brainstem, and cerebellum volumetry were compared in patients with ICA/PICA with respect to healthy controls and patients with focal seizures without peri-ictal breathing disorders.RESULTSA total of 69 patients (mean age 35.7 years; 42% female) with 406 focal-onset seizures were analyzed. ICA was recorded in 71 seizures (17%) in 27 patients. PICA was recorded in 24 seizures in 12 patients (10 with temporal lobe epilepsy) corresponding to 5.9% of all recorded seizures. Notably, PICA was observed only in seizures showing ictal apnea (in 33.8%). In 11 seizures with PICA, a single apneic event starting in the ictal and extending to the postictal period was observed. In 13 seizures, multiple apneic events were present in the postictal period (range 2-8). Seizures with PICA showed a longer peri-ictal apnea time (mean 75 seconds vs 40 seconds; p = 0.007) and a longer time to restore a regular rhythmic breathing after seizure termination (mean 173 seconds vs 42 seconds; p < 0.001) than seizures with self-limiting ictal apnea. Amygdala volumes ipsilateral to the epileptogenic zone were larger in patients with ICA/PICA compared with controls and patients without seizure-related apnea.DISCUSSIONPICA occurs in approximately 6% of focal seizures and is associated with extended apnea time and an enlarged amygdala ipsilaterally to the epileptogenic zone. Our data support the existence of a continuum from ictal to PICA and highlight the importance of cardiorespiratory recordings in LTVEM.","PeriodicalId":19256,"journal":{"name":"Neurology","volume":"25 1","pages":"e213856"},"PeriodicalIF":9.9,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144684140","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aimed to determine trajectories and outcomes of development and adaptive function.METHODSThis was a mixed retrospective cross-sectional study of individuals from an international SCN2A Natural History Study, who had neurologic/neurodevelopmental disorders due to an SCN2A variant. Individuals with SCN2A intragenic variants were grouped into early-onset (EO) and late-onset (LO) phenotypic groups; those with SCN2A-containing 2q24.3 copy number variants (CNVs) were considered separately. We collected medical and developmental history from parents/caregivers and medical records. Adaptive function and behavior were characterized using functional classification system levels and Vineland Adaptive Behavior Scales-3 (VABS-3) Parent/Caregiver Form. We repeated analyses on individuals with variants known to result in gain-of-function (GOF, typically EO phenotypes) or loss-of-function (LOF, typically LO phenotypes).RESULTSA total of 100 individuals (age 0.1-21.9 years, 39% female) were studied. Phenotypic groups were EO (n = 44), LO (n = 48), and 2q24.3 CNV (n = 8). Developmental delay/intellectual disability was present in 91 of 100, and 23 of 80 individuals (29%) older than 2 years had autism spectrum disorder. Of people older than the typical age for skill attainment, 59 of 95 (62%) could sit and 48 of 88 (55%) could walk. In addition, 27 of 86 individuals (31%) spoke more than 1-5 single words, and 24 of 74 (32%) followed two-step commands. Median VABS-3 Adaptive Behavior Composite (ABC) scores were as follows: the EO phenotypic group had a score of 56 (range 21-110), the LO phenotypic group had a score of 45 (range 20-89), and 5 of 6 with a 2q24.3 CNV had an ABC score of <45. The EO phenotypic group had 3 distinct subgroups, consistent with \"benign,\" \"intermediate,\" and \"severe\" definitions previously published. The LO phenotypic group showed a continuum of severity, without distinct clusters. However, clinically relevant differences in motor function were evident when subgrouped by seizure-onset age; a lower proportion with earlier seizure onset (age <18 months) were independently ambulant than those with later onset or no seizures (5/15 [33%] vs 10/12 [83%] vs 14/15 [93%], p < 0.01). Analyses of individuals with confirmed GOF/LOF variants (n = 57) showed similar results to the EO/LO analyses.DISCUSSIONThe spectrum of developmental impairments and adaptive function in SCN2A-related disorders is extremely broad. Phenotypic subgroups provide prognostic information and critically inform clinical trial design.","PeriodicalId":19256,"journal":{"name":"Neurology","volume":"282 1","pages":"e213868"},"PeriodicalIF":9.9,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144684142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
