Background: There have been limited data on idiopathic intracranial hypertension (IIH) in Asians and there remain uncertainties whether a cerebrospinal fluid (CSF) pressure of 250 mm CSF is an optimum diagnostic cutoff. The aims of the present study included (1) characterization of IIH patients in Taiwan, (2) comparisons among different diagnostic criteria for IIH, and (3) comparisons between patients with CSF pressures of > 250 and 200-250 mm CSF.
Methods: This retrospective study involved IIH patients based on the modified Dandy criteria from two tertiary medical centers in Taiwan.
Background And Objectives: Blood-brain barrier (BBB) disruption has been proposed to be important in the pathogenesis of reversible cerebral vasoconstriction syndrome (RCVS), but not all patients present an identifiable macroscopic BBB disruption; that is, visible contrast leakage on contrast-enhanced T2 fluid-attenuated inversion recovery imaging. This study aimed to evaluate microscopic BBB permeability and its dynamic change in patients with RCVS.
Methods: This prospective cohort implemented 3T dynamic contrast-enhanced MRI.
Background and Purpose- Reversible cerebral vasoconstriction syndrome (RCVS) has a unique temporal course of vasoconstriction. Blood-brain barrier (BBB) breakdown is part of the pathophysiology of RCVS, but its temporal course is unknown. We aimed to investigate the temporal profile of BBB breakdown and relevant clinical profiles in a large sample size.

However, heterozygous mutations were recently identified to be associated with autosomal dominant cerebral small vessel disease (SVD). The present study aims at investigating the clinical features, frequency, and spectrum of mutations in a Taiwanese cohort with SVD.

We aimed to evaluate the association between migraine and VTE and to examine whether demographics or comorbid risk factors modulate VTE development.
Methods: -We conducted a cohort study accessing a nationwide claims-based database with an adult cohort of 102,159 neurologist-diagnosed migraine patients, and 102,159 nonheadache comparison subjects, matched on sex and propensity score for the diagnosis of migraine.
Objective: We aimed to investigate whether reversible cerebral vasoconstriction syndrome (RCVS) could recur and to identify the potential predictors of recurrence in a large cohort of patients.
Methods: This study followed a cohort of 210 patients with RCVS in a hospital-based headache center from 2000 to 2012. All patients were regularly followed up by telephone after remission for RCVS and were particularly asked to return to our hospital immediately if they developed new acute, severe (i.
Objective: To evaluate the association between migraine and Bell palsy and to examine the effects of age, sex, migraine subtype, and comorbid risk factors for Bell palsy.
Methods: This nationwide cohort study was conducted using data from the Taiwan National Health Insurance Research Database. Subjects aged 18 years or older with neurologist-diagnosed migraine from 2005 to 2009 were included.
