    Changes in Prevalence of Idiopathic Intracranial Hypertension in the United States Between 2015 and 2022, Stratified by Sex, Race, and Ethnicity · 2024 · DOI

  • Additional neuroimaging signs have been proposed and used with contradictory results; thus, prospective evidence is needed to improve diagnostic accuracy.

    Magnetic Resonance Imaging Signs of Idiopathic Intracranial Hypertension · 2024 · DOI

  • There is a lack of research on the use of integrative therapies in chronic neurological conditions. Conventional therapies often leave residual neurological deficits and functional impairments.

  • Future studies should investigate the clinical implications of anatomical variations of the dural venous sinuses. Future studies should develop and validate a classification system for CS patterns. Future studies should examine the relationship between anatomical variations and venous pathologies.

    Morphological variations of the dural venous sinuses: a cadaveric study · 2026 · DOI

  • There is a lack of understanding of the anatomical variations of the dural venous sinuses. There is a need for a framework for understanding and classifying these variations.

    Morphological variations of the dural venous sinuses: a cadaveric study · 2026 · DOI

  • Further studies are needed to validate the use of PHOMS UP thickness as a biomarker for true papilloedema. Studies should investigate the use of OCT scanning in different patient populations. Research should focus on developing new treatments for papilloedema based on the study's findings.

    Optical coherence tomography measurement of retinal layers above the peripapillary hyperreflective ovoid mass-like structure in true papilloedema and pseudo-papilloedema · 2026 · DOI

  • There is a need for simple, rapid, non-invasive tools for distinguishing pseudo-papilloedema from true papilloedema. Current methods for diagnosing papilloedema are often invasive and time-consuming.

    Optical coherence tomography measurement of retinal layers above the peripapillary hyperreflective ovoid mass-like structure in true papilloedema and pseudo-papilloedema · 2026 · DOI

  • The diagnosis of pediatric idiopathic intracranial hypertension can be challenging. There is a need for more accurate and efficient diagnostic tools for pediatric idiopathic intracranial hypertension.

    Diagnostic value of machine-learning using conventional magnetic resonance imaging markers for pediatric idiopathic intracranial hypertension: a retrospective study · 2026 · DOI

  • External gen- eralizability to other scanners, sequences, and case mixes therefore remains to be established. Consequently, a biologically grounded prepubertal-versus- postpubertal subgroup analysis could not be performed, and whether performance differs across pediatric age strata remains unknown.

    Diagnostic value of machine-learning using conventional magnetic resonance imaging markers for pediatric idiopathic intracranial hypertension: a retrospective study · 2026 · DOI

  • The study had a retrospective design. The sample size was limited to 100 neonates. The study did not include a control group.

    NeoCVST Score: Classification of Brain Injury Secondary to Neonatal Cerebral Venous Sinus Thrombosis · 2026 · DOI

  • There is no scale to characterize the spectrum of brain injury secondary to neonatal CVST. Existing pediatric ICH classification systems could not adequately characterize hemorrhage in neonatal CVST.

    NeoCVST Score: Classification of Brain Injury Secondary to Neonatal Cerebral Venous Sinus Thrombosis · 2026 · DOI

  • Further studies are needed to explore the long-term outcomes of patients with hard drusen. Research is needed to investigate the underlying mechanisms of the associations between lipid metabolism and choriocapillaris microvascular impairment. Studies should examine the effectiveness of novel therapeutic strategies for AMD.

    Systemic lipid abnormalities and choriocapillaris flow deficits in patients with hard drusen · 2026 · DOI

  • The precise trajectory of the conversion of small hard drusen to larger soft drusen and ultimately to AMD remains incompletely characterized. The underlying mechanisms of the associations between lipid metabolism and choriocapillaris microvascular impairment are not fully understood.

    Systemic lipid abnormalities and choriocapillaris flow deficits in patients with hard drusen · 2026 · DOI

  • The clinical challenge lies in distinguishing benign primary headache disorders from secondary causes in pregnancy. There is a need for increased awareness of the importance of red-flag recognition, imaging selection, and coordinated specialty care.

    Headache in Pregnancy: A Case Series of Secondary and Benign Causes with Diagnostic Pathways · 2026 · DOI

  • The association between venous recanalization and clinical prognosis remains uncertain. The role of IDA in CVT pathogenesis is not fully understood.

    Clinical Recovery Without Recanalization in Iron Deficiency Anemia-Associated Cerebral Venous Thrombosis: A Case Report · 2026 · DOI

  • The importance of neuroimaging in children with headache who have red flag features - The need for early diagnosis and treatment of brain tumors in children

    Headache in a Young Child Revealing an Unexpected Intracranial Tumor · 2026 · DOI

  • Advanced thrombophilia testing, including genet- ic analysis for factor V Leiden and prothrombin gene mutations, was not performed because of limited availability. Toxicological identification of the scorpi- on species was also not possible. cONcLUSION Ischemic stroke is a rare but important complica- tion of scorpion envenomation. Venom-induced au- tonomic dysregulation, endothelial injury, inflamma- tory activation, and prothrombotic mechanisms may collectively contribute to cerebrovascular thrombo- sis.
