Effectiveness of Diagnostic Strategies in Suspected Delayed Cerebral Ischemia: A Decision Analysis Clinical Sciences
Conclusions— Imaging studies to test for the presence of angiographic vasospasm or perfusion deficits in patients with clinical DCI do not seem helpful in selecting which patients should undergo treatment and may not improve outcomes. Future directions include validating these results in prospective cohort studies.

Sleep Duration, Kidney Function, and Their Effects on Cerebral Small Vessel Disease in Elderly Hypertensive Patients.
CONCLUSIONS: In the present study, short sleep duration was a positive significant determinant for WMH and PVH in elderly hypertensives. Sleep duration might serve as a strong determinant for white matter lesions especially in those without CKD. PMID: 25559119 [PubMed - as supplied by publisher]

Isolated MCA Disease in Patients Without Significant Atherosclerotic Risk Factors: A High-Resolution Magnetic Resonance Imaging Study Clinical Sciences

Cerebral Perivascular Spaces Visible on Magnetic Resonance Imaging: Development of a Qualitative Rating Scale and its Observer Reliability
Conclusions: We developed a more inclusive and robust visual PVS rating scale allowing rating of all grades of PVS severity on structural brain imaging. The revised PVS rating scale has good observer reliability for basal ganglia and centrum semiovale PVS, best for basal ganglia PVS, and moderate reliability for midbrain PVS. Agreement is influenced by PVS severity and the presence of background features of SVD. The current scale can be used in further studies to assess the clinical implications of PVS.Cerebrovasc Dis 2015;39:224-231

Acute Response of Right Ventricular Function to Iloprost Inhalations in Patients with Pulmonary Arterial Hypertension: Preliminary Evaluation 
with Cardiac Magnetic Resonance Imaging
Background and objective Pulmonary arterial hypertension (PAH) is a progressive disorder characterized by abnormally elevated blood pressure of the pulmonary circulation. Without treatment, PAH progresses rapidly to right ventricular (RV) failure and even death. Cardiac magnetic resonance imaging (CMRI) has been an accurate and reproducible tool to assessment of RV morphology and function, which are important factors in the prognosis of patients with PAH. The aim of this study is to investigate acute RV response to inhalation of aerosolized iloprost in patients with PAH using CMRI. Method From March 2012 to March 2014, 48 ...

Short-Term Blood Pressure Variability Relates to the Presence of Subclinical Brain Small Vessel Disease in Primary Hypertension Cerebral Small Vessel Disease
Blood pressure (BP) variability is associated with stroke risk, but less is known about subclinical cerebral small vessel disease (CSVD). We aimed to determine whether CSVD relates to short-term BP variability independently of BP levels and also, whether they improve CSVD discrimination beyond clinical variables and office BP levels. This was a cohort study on asymptomatic hypertensives who underwent brain magnetic resonance imaging and 24-hour ambulatory BP monitoring. Office and average 24-hour, daytime and nighttime BP levels, and several metrics of BP variability (SD, weighted SD, coefficient of variation, and average ...

Vasospastic Amaurosis Fugax Diagnosed by Cerebral Angiography
We report a case of recurrent monocular blindness presumed to be caused by vasospasm, demonstrated by digital subtraction angiography. Case report: A 65-year-old man presented with recurrent visual loss in the left eye for 2 years. He had histories of hypertension, cigarette smoking, and May–Thurner syndrome. The symptom occurred variably from twice a day to once a week and usually lasted for 5 minutes. Brain magnetic resonance imaging, magnetic resonance angiography, and ophthalmologic evaluation did not reveal any abnormality.

Hypertensive Target Organ Damage and Longitudinal Changes in Brain Structure and Function: The Second Manifestations of Arterial Disease-Magnetic Resonance Study Cognitive Decline and Blood Pressure
We examined the association of hypertensive target organ damage with longitudinal changes in brain structure and function within the Second Manifestations of Arterial Disease–Magnetic Resonance (SMART-MR) study. Renal function, albuminuria, and left ventricular hypertrophy on electrocardiography were measured in 663 patients with manifest arterial disease (mean age, 57±9 years; 81% men). Automated brain segmentation was used to quantify progression of global brain atrophy (change in brain parenchymal fraction) and progression of cerebral small vessel disease on 1.5T magnetic resonance imaging, and memory and e...

Percutaneous Transluminal Angioplasty Improved Posterior Reversible Encephalopathy Syndrome due to Renovascular Hypertension
A 51-year-old man was admitted to our hospital complaining of preceding throbbing headache and tonic convulsions. Headache and convulsive seizure disappeared and his consciousness recovered to alert within 2 hours after onset. Neurological examination showed no abnormal findings. Laboratory examinations revealed high low-density lipoprotein cholesterol (179 mg/dL), renin (42 ng/mL/hour), aldosterone (265 pg/mL), noradrenaline (1031 pg/mL), and dopamine (79 pg/mL). In brain magnetic resonance imaging (MRI), fluid-attenuated inversion recovery, but not the diffusion-weighted image, showed high signal intensities in...

Valacyclovir and Acyclovir Neurotoxicity With Status Epilepticus
We present the case of a 52-year-old man with hypertension, diastolic congestive heart failure, end-stage renal disease on hemodialysis 3 times a week and a remote history of a hemorrhagic stroke who presented to the emergency department with a vesicular rash on his left arm. The rash was observed to be in a dermatomal distribution, and a diagnosis of herpes zoster was made. The patient was discharged home on valacyclovir 1 g 3 times a day for a duration of 7 days. The patient took 2 doses of valacyclovir before presenting to the hospital again with irritability and hallucinations. Over the next several days, the patient's...

Functional MRI 2.0 : ²³Na and CEST imaging.
Abstract In recent years the purely morphological magnetic resonance imaging (MRI) has been increasingly flanked by so-called functional imaging methods, such as diffusion-weighted imaging (DWI), to obtain additional information about tissue or pathological processes. This review article presents two MR techniques that can detect physiological processes in the human body. In contrast to all other functional MR imaging techniques, which are based on hydrogen protons, the first technique presented (X-nuclei imaging) uses the spin of other nuclei for imaging and consequently allows a completely different insight into...

Association of Aortic Stiffness With Cognition and Brain Aging in Young and Middle-Aged Adults: The Framingham Third Generation Cohort Study Epidemiology/Population
In conclusion, aortic stiffness was associated with cognitive function and markers of subclinical brain injury in young to middle-aged adults. Prospective studies are needed to examine whether aortic stiffening in young adulthood is associated with vascular cognitive impairment later in life.

Assessment of enlarged perivascular spaces and their relation to target organ damage and mild cognitive impairment in patients with hypertension
ConclusionsBasal ganglia EPVS are associated with the presence of microalbuminuria and poor adherence to antihypertensive drugs. The BG EPVS relation with MCI is not independent of the presence of other cerebral small vessel disease markers.
