Attention and Motor Network Connectivity Predicts Spatial Neglect after Right Brain Stroke

To test whether patients with functionally-defined spatial neglect, as compared to stroke controls, had different patterns of resting state functional connectivity between the motor, dorsal and ventral attention networks, as indicated by functional Magnetic Resonance Imaging (fMRI).

Children with SSADH deficiency usually manifest with developmental delay, behavioral symptoms, language dysfunction, seizures, hypotonia, extrapyramidal symptoms, and ataxia. Diagnosis of SSADH deficiency is established by an abnormal urine organic acid pattern, including increased excretion of 4-hydroxybu...

CONCLUSIONS: This pilot study has visualized the effects of stroke lesions on the functional brain networks of individual patients. Consideration of the neurobiologic mechanisms underlying the differences between their connectograms has yielded new hypotheses about differences in the effects of stroke lesions.

Abstract Although the prevalence of muscle weakness in the general population is uncertain, it occurs in about 5% of U.S. adults 60 years and older. Determining the cause of muscle weakness can be challenging. True muscle weakness must first be differentiated from subjective fatigue or pain-related motor impairment with normal motor strength. Muscle weakness should then be graded objectively using a formal tool such as the Medical Research Council Manual Muscle Testing scale. The differential diagnosis of true muscle weakness is extensive, including neurologic, rheumatologic, endocrine, genetic, medication- or tox...

We present the case of a patient with a medical history of type 2 diabetes mellitus (DM) who experienced disseminated cutaneous VZV infection followed by multiple cerebral infarcts associated with VZV vasculopathy. Brain magnetic resonance imaging revealed multiple hyperintense lesions over the bilateral deep white matter and basal ganglia. A skin biopsy revealed small-vessel leukocytoclastic vasculitis with neutrophilic, lymphocytic, and eosinophilic infiltration. This case report describes the rare finding of cutaneous leukocytoclastic vasculitis in VZV infection and highlights that VZV infection is an uncommon but criti...

AbstractPurpose of ReviewTranscarotid artery revascularization (TCAR) is a novel hybrid procedure that reverses carotid flow and places a stent using surgical access of the carotid artery in the neck under local anesthesia. We discuss the indications for carotid revascularization, the clinical rationale for TCAR, and evidence for its potential role in the management of carotid stenosis.Recent FindingsResults from pre-clinical studies, prospective single-arm studies, and comparative analyses of registry data indicate that TCAR results in low amounts of periprocedural microembolization, cerebral lesions detectable on magneti...

ConclusionThe study demonstrates that aging changes blood flow but preserves blood and CSF interactions. We also showed that many parameters related to blood and CSF flows differ between young and elderly adults.

We report a patient with probable posterior cortical atrophy who demonstrated lower right-sided quadrantic visuospatial neglect, together with allocentric vertical neglect. METHODS/RESULTS: A 68-year-old man initially noted deficits in reading and writing. Subsequently, he developed other cognitive deficits. On vertical line bisections, he deviated upward, and on horizontal line bisections, he deviated to the left. These deviations together suggest that this man's neglect might be most severe in his right (head/body-centered) lower (below eye level) visual space. When attempting to perform vertical line bisections in ...

In this study, we investigated the link between AF and senescence markers through the assessment of protein expression in the tissue lysates of human appendages from patients in AF, including paroxysmal (PAF) or permanent AF (PmAF), and in sinus rhythm (SR). The major findings of the study indicated that the progression of AF is strongly related to the human atrial senescence burden as determined by p53 and p16 expression. The stepwise increase of senescence (p53, p16), prothrombotic (TF), and proremodeling (MMP-9) markers observed in the right atrial appendages of patients in SR, PAF, and PmAF points toward multiple inter...

However, there has been little research directly examining cardiac function in schizophrenia. AIMS: To investigate cardiac structure and function in individuals with schizophrenia using cardiac magnetic resonance imaging (CMR) after excluding medical and metabolic comorbidity. METHOD: In total, 80 participants underwent CMR to determine biventricular volumes and function and measures of blood pre...

This study assessed the safety and usefulness of pretreatment using a high-dose strong statin (HDSS) to reduce the periprocedural ischemic complications of CAS. We analyzed 117 carotid lesions treated by CAS that were evaluated with magnetic resonance imaging (MRI) within 48  h after the procedure. For 67 lesions, an HDSS (rosuvastatin 20 mg or atorvastatin 40 mg daily) were prescribed from at least 14 days before CAS to at least 14 days after procedure (HDSS group). Clinical and angiographic data, as well as in-hospital outcomes, of the HDSS group were retrospecti vely compared with 50 lesions wit...
