α-Synuclein Pathology in Idiopathic Normal Pressure Hydrocephalus: Evidence for Concomitant Synucleinopathy and Clinical Implications

Efstratios-Stylianos Pyrgelis, George P. Paraskevas, Vasilios C. Constantinides, Fotini Boufidou et autres

Idiopathic normal pressure hydrocephalus (iNPH) is a potentially reversible neurological disorder characterized by gait impairment, cognitive decline, and urinary dysfunction. Despite improvements in diagnostic criteria and neuroimaging techniques, accurate diagnosis remains challenging due to clinical overlap with neurodegenerative diseases, particularly Alzheimer’s disease …

Clinical Significance of Microembolic Signal Detection in Acute Ischemic Stroke: Insights Into Ongoing Cerebral Embolization and Occult Etiologies

Eleni Bakola, Lina Palaiodimou, Aikaterini Theodorou, Maria Chondrogianni et autres

BACKGROUND AND PURPOSE: Transcranial Doppler (TCD) detects microembolic signals (MES), reflecting ongoing cerebral embolization. MES have been studied across stroke subtypes and may clarify etiology, monitor treatment, and predict recurrence. We aimed to determine the prevalence of MES in acute ischemic stroke …

Progressive supranuclear palsy against everyone else: a look into the specificity of MRI markers

Vasilios C. Constantinides, Maria-Evgenia Brinia, Ioanna Kapsali, Nikolaos Giagkou et autres

INTRIDUCTION: Diagnostic accuracy of the clinical diagnosis of progressive supranuclear palsy (PSP) is suboptimal, due to its' clinical heterogeneity. Multiple MRI markers have been introduced in an effort to enhance clinical diagnosis. OBJECTIVES: This study compared the diagnostic accuracy of linear, planimetric …

Quantitative measurements of α-synuclein seeds in CSF inform diagnosis of synucleinopathies

Ilham Y. Abdi, Indulekha P. Sudhakaran, Simona S. Ghanem, Nishant N. Vaikath et autres

Diagnosing α-synucleinopathies and assessing target engagement in trials is hindered by the lack of reliable biomarkers. Here, we introduce a first-in-kind quantitative, highly sensitive, and disease-specific diagnostic assay, named Seeding Amplification ImmunoAssay (SAIA), developed and validated to detect synucleinopathy-linked disorders. To this …

In search of the optimal MRI marker for progressive supranuclear palsy: a large, single-center, retrospective study on the effect of phenotype, diagnostic certainty and disease duration

Vasilios C. Constantinides, Nikolaos Giagkou, Maria-Evgenia Brinia, Ioanna Kapsali et autres

INTRODUCTION: Multiple MRI markers have been introduced as surrogate markers of progressive supranuclear palsy (PSP). Midbrain surface, midbrain/pons surface ratio (M/P) and the Magnetic Resonance Parkinsonism Index (MRPI) have produced high diagnostic accuracy in differentiating PSP from other parkinsonian disorders. A systematic …

A Less Common Anatomical Variant of Bilateral Multiple Lesser Metatarsal Sesamoids With Radiologic and Clinical Correlation

Christos Lyrtzis, Dimitra Mpei, George P. Paraskevas, Nikolaos K. Lazaridis

Accessory or supernumerary bones are bones that are not normally present in the body but can be found as an anatomical variant. While hallucal sesamoids are common, lesser metatarsal sesamoids are uncommon and often underreported. These ossicles develop through endochondral ossification and …
