Article Abstract
Understanding how cnidarians pattern their nervous systems can provide insight into the ancestral mechanisms of neurogenesis that are shared with bilaterians, shedding light on the evolution of nervous systems. While previous studies have revealed deeply conserved mechanisms for neural induction and progenitor selection between cnidarians and bilaterians, less is known about how distinct neuronal subtypes are specified over time in cnidarians. We utilized single-cell mRNA sequencing to profile expressing cells across embryonic and planula-larva stages of neurogenesis, and functional experiments identified a dynamic role for over time. Our analysis revealed that unique neuronal subtypes emerge at different developmental stages, providing evidence for temporal patterning in developing cnidarian nerve nets. This can provide a foundation to better our understanding of neurogenic gene regulatory networks, and to compare neurogenesis across cnidarians, and with bilaterians, to improve our knowledge of nervous system evolution.

Retinal biomarkers in cognitive impairment and dementia: Structural, functional, and molecular insights.
Alzheimers Dement
September 2025
Department of Neurology, Beijing TianTan Hospital, Capital Medical University, Beijing, China.
Cognitive impairment and dementia, including Alzheimer's disease (AD), pose a global health crisis, necessitating non-invasive biomarkers for early detection. This review highlights the retina, an accessible extension of the central nervous system (CNS), as a window to cerebral pathology through structural, functional, and molecular alterations. By synthesizing interdisciplinary evidence, we identify retinal biomarkers as promising tools for early diagnosis and risk stratification.

Unlabelled: Leptomeningeal metastasis (LM) is a severe complication of solid malignancies, including lung adenocarcinoma, characterized by poor prognosis and diagnostic challenges. This study assesses whether curvilinear peri-brainstem hyperintense signals on MRI are a characteristic feature of LM in lung adenocarcinoma patients.
Methods: This retrospective study analyzed data from multiple centers, encompassing lung adenocarcinoma patients with peri-brainstem curvilinear hyperintense signals on MRI between January 2016 and March 2022.
Rapidly Progressive Primary Central Nervous System Vasculitis: A Rare Case with Multifocal Small and Medium Vessel Involvement.

Introduction: Primary central nervous system vasculitis (primary CNS vasculitis) is a rare inflammatory disorder that affects small-to-medium-sized cerebral vessels, often leading to recurrent strokes. Diagnosis is vague due to non-specific neurological symptoms. Imaging findings, cerebrospinal fluid (CSF) analysis and exclusion of systemic vasculitis are essential for diagnosis.

Background: Invasive central nervous system (CNS) aspergillosis is rare among human immunodeficiency virus (HIV)-positive patients due to preserved neutrophil function, despite significant CD4+ T-cell depletion. Diagnosis typically requires histopathologic confirmation, but polymerase chain reaction (PCR) testing has introduced new challenges due to its high sensitivity but limited specificity.
Case Presentation: We describe a newly diagnosed 43-year-old HIV-positive male with concurrent Hodgkin lymphoma who presented with progressive neurological decline and a ring-enhancing brain lesion.
Progress in the Study of Diagnostic Methods for Central Acute Vestibular Syndrome of a Vascular Cause.

Acute vestibular syndrome (AVS) is characterized by the sudden onset of dizziness or vertigo, accompanied by nausea, vomiting, gait instability, and nystagmus, lasting for more than 24 hours and often persisting for several days to weeks. Central AVS primarily involves central vestibular structures, such as the brainstem and cerebellum, and is most commonly caused by ischemic stroke in the posterior circulation. When acute posterior circulation infarction presents solely with isolated dizziness or vertigo, without other symptoms of central nervous system damage, it is often misdiagnosed as a peripheral vestibular disorder, this can lead to serious consequences.
