OBJECTIVES Although diffusion tensor imaging (DTI) is widely studied to assess the motor outcome after ischaemic stroke, there is paucity of data regarding outcomes of intracerebral haemorrhage (ICH). The aim of this study was to determine the DTI data from different locations along the corticospinal tract (CST) and association to motor outcome. METHODS(More)
BACKGROUND To determine whether or not jugular venous reflux (JVR) is associated with structural brain parenchyma changes in individuals with mild cognitive impairment (MCI) and Alzheimer's disease (AD). METHODS 16 AD patients (mean (SD): 81.9 (5.8) years), 33 MCI patients (mean (SD): 81.4 (6.1) years) and 18 healthy elderly controls (mean (SD): 81.5(More)
BACKGROUND Jugular venous reflux (JVR) has been reported to cause cough syncope via retrograde-transmitted venous hypertension and consequently decreased cerebral blood flow (CBF). Unmatched frequencies of JVR and cough syncope led us to postulate that there should be additional factors combined with JVR to exaggerate CBF decrement during cough, leading to(More)
Superficial siderosis is a rare disease with a low incidence of known etiologies and successful management in clinical practice. The presence of a fluid collection secondary to a dural tear has been reported in patients and is considered to be related to superficial siderosis. We report on a patient with superficial siderosis who had a multi-lobulated(More)
To determine whether jugular venous reflux (JVR) is associated with cerebral white matter changes (WMCs) in individuals with Alzheimer's disease (AD), we studied 12 AD patients 24 mild cognitive impairment (MCI) patients, and 17 elderly age- and gender-matched controls. Duplex ultrasonography and 1.5T MRI scanning was applied to quantify cerebral WMCs [T2(More)
OBJECTIVE Spinal cord infarction (SCI) is a rare complication of vertebral artery dissection (VAD). Its clinical features and outcomes have not yet been well documented. METHODS In addition to reporting a case with bilateral SCI caused by left VAD, we performed a systematic review of the literature conducted through a PubMed search. RESULTS A total of(More)
BACKGROUND Subcortical ischemic vascular dementia (SIVD) caused by small-artery disease, and hypoperfusion is a major cause of vascular cognitive impairment. Little is known about the relationship between sleep disturbance and white matter hyperintensity (WMH). We investigated the association between sleep disturbance and WMH, measured by magnetic resonance(More)
BACKGROUND The etiology of transient monocular blindness (TMB) in patients without carotid stenosis has been linked to ocular venous hypertension, for their increased retrobulbar vascular resistance, sustained retinal venule dilatation and higher frequency of jugular venous reflux (JVR). This study aimed to elucidate whether there are anatomical(More)
OBJECTIVE Panic disorder (PD) is characterized by panic attacks accompanied with respiratory symptoms. Internal jugular vein (IJV) alters its hemodynamics in response to respiration and which might cause cerebral blood flow (CBF) changes. In the present study, we compared (1) respiratory-related IJV hemodynamics and (2) CBF changes during Valsalva maneuver(More)
