Background: Neurology and literature have a complex interface; one of the facets is that of works inspired by grief on the passing of a beloved one due to a neurological disease.

Summary: In Memoriam A.H.H., written by Alfred Tennyson and published in 1850 in response to the untimely death of Arthur Henry Hallam, is one such elegy, which had a profound impact in Tennyson's body of work and on the history of Victorian poetry in general. In this review, the author delineates biographical notes of both men before analyzing the disease and death of Arthur Hallam due to hemorrhagic stroke.

Key messages: By evaluating Hallam's autopsy report and contemplating the different hypotheses on the etiology of his stroke, as well as how his death due to catastrophic neurological disease was memorialized in verse, neurologists may gain better insight on the interface between neurology and literature inspired by grief.

Introduction: Cardiology and cardiothoracic surgery are among the specialties that most commonly require neurology inpatient consultations. We aimed to study the neurology referrals by the cardiovascular-specialized hospital included in our tertiary hospital center.

Methods: Retrospective study of consecutive patients referred for neurology inpatient consultation between January 1, 2020, and December 31, 2022. We analyzed referrals, patients' characteristics, and the approach taken. A detailed subanalysis was performed for patients diagnosed with acute ischemic stroke (AIS).

Results: 143 patients were observed (mean age 67.3 years, 46 [32.2%] females). Most frequent referral reasons were suspected AIS deficits (39.2%), altered mental status (19.6%), suspected seizures (13.3%), and neuroprognostication (11.9%). Mean referral-to-consult time was 2.7 days, and 117 (81.8%) consults were in-person. Additional investigation, treatment changes, and outpatient clinic referral were proposed, respectively, in 79.7%, 60.1%, and 19.6% of patients. Most common diagnoses were AIS (45.5%), hypoxic-ischemic encephalopathy (18.9%), and delirium (7.0%). Regarding patients with AIS (n = 62), most common stroke causes were post-cardiac procedure (44.6%), infective endocarditis (18.5%), aortic dissection (10.8%), acute myocardial infarction (10.8%), and anticoagulant withdrawal in patients with atrial fibrillation (6.2%). Thirty-four AIS patients were diagnosed less than 24 h since last seen well, of which four (6.2%) were treated (three with thrombolysis and one with mechanical thrombectomy).

Conclusion: AIS is the most common reason for referral in our cardiovascular hospital. Our results highlight the importance of the availability of a neurologist/neurohospitalist with stroke expertise for consultation of inpatients admitted in a specialized cardiovascular hospital.

Combined central and peripheral demyelination (CCPD) is a rare disease characterized by demyelinating lesions in both the central nervous system (CNS) and peripheral nervous system (PNS). CCPD can present with acute, subacute, or chronic onset. The initial symptom may be of CNS origin, PNS origin, or both. The clinical manifestations of CCPD are quite heterogeneous, and there are no well-defined diagnostic criteria. In MRI imaging of CCPD cases, demyelinating lesions can be seen in areas such as the brain, cerebellum, brainstem, optic nerve, and spinal cord. Common electromyography (EMG) findings in patients with CCPD include decreased motor nerve conduction velocities, decreased or absent sensory nerve action potentials, prolonged F-wave latency, and decreased amplitude of compound muscle action potentials. Neurofascin (NF) is a transmembrane protein and anti-neurofascin (anti-NF) antibodies directed against NF can be positive in cases of CCPD. Four main NF polypeptides are produced by alternative splicing: NF 186, NF 180, NF 166, and NF 155. The investigation of anti-NF in CCPD cases is therefore important for etiological considerations. Here, we discussed three cases diagnosed with CCPD based on clinical, neuroimaging, EMG, and anti-NF antibody results in light of the literature.

Introduction: Long COVID can also lead to neurological sequelae that affect existing diseases. This study explored how COVID-19 infection affects neurological patients and the relationship between long COVID and exacerbating factors.

Methods: This retrospective study was conducted on 85 patients with neurological diseases after COVID-19 at the Neurology Department, Inje University Busan Paik Hospital, Korea. The data were collected between August and October 2022. The patients had a medical history, including COVID-19 infection, and completed symptom questionnaires. A long COVID questionnaire consisting of 35 inquiries in 10 categories was completed. Anxiety, depression, fatigue, functional difficulties, QOL, and health status changes were assessed.

Results: The analysis comprised 85 participants (age: 56.4 ± 15.2 years; 63.5% women). Of the categories, neurological symptoms (68.2%) were the most prevalent, followed by systemic symptoms (64.7%) and cardiopulmonary symptoms (56.5%). Anxiety, depression, and fatigue symptoms were reported by 36.5%, 34.1%, and 42.4% of the participants. Subjective neurological deterioration after COVID-19 was reported in 28 participants (28/81, 34.6%). Anxiety, depression, and fatigue were influenced by long COVID symptoms and the subjective deterioration of neurological conditions.

Conclusion: This study analyzed the long COVID symptoms in patients with preexisting neurological conditions and their impact on mental health and quality of life. One-third of the participants reported a subjective worsening of their preexisting neurological conditions. This study highlights the need for comprehensive follow-ups and a multidisciplinary approach for patients with neurological conditions and prolonged COVID-19 symptoms.

Introduction: Brain arteriovenous malformations (BAVMs) are high-flow intracranial vascular malformations characterized by the direct connection of arteries to veins without an intervening capillary bed. They are one of the main causes of intracranial hemorrhage and epilepsy, although morbidity is low. Angiogenesis, heredity, inflammation, and arteriovenous malformation syndromes play important roles in BAVM formation. Animal experiments and previous studies have confirmed that NOTCH4 may be associated with BAVM development. Our study identifies a connection between NOTCH4 gene polymorphisms and BAVM in a Chinese Han population.

Methods: We enrolled 150 patients with BAVMs confirmed by digital subtraction angiography (DSA) in the Department of Neurosurgery, Zhujiang Hospital, Southern Medical University from June 2017 to July 2019. Simultaneously, 150 patients without cerebrovascular disease were confirmed by computed tomography angiography/magnetic resonance angiography/DSA. DNA was extracted from peripheral blood and NOTCH4 genotypes were identified by PCR-ligase detection reaction. The χ2 test or Fisher's exact test was used to evaluate the differences in allele and genotype frequencies between the BAVM group, control group, bleeding group, and other complications.

Results: Two single-nucleotide polymorphisms (SNPs), rs443198 and rs438475, were significantly associated with BAVM. No SNP genotypes were significantly associated with hemorrhage or epilepsy. SNPs rs443198_AA-SNP and rs438475_AA-SNP may be associated with a lower risk of BAVM (p = 0.011, odds ratio (OR) = 0.459, 95% confidence interval (CI): 0.250-0.845; p = 0.033, OR = 0.759, 95% CI: 0.479-1.204).

Conclusion: NOTCH4 gene polymorphisms were associated with BAVM and may be a risk factor in a Chinese Han population.
