Predictive Value of Coronary Blood Flow for Future Cardiovascular Events in Patients with Atrial Fibrillation
Atrial fibrillation (AF) is associated with impaired coronary flow and diminished myocardial perfusion [1–3]. In a previous study, we demonstrated that patients with AF in the absence of obstructive coronary artery disease (CAD) have significantly higher Thrombolysis in Myocardial Infarction (TIMI) frame count (TFC) for all three coronary vessels compared to the control subjects without AF [1]. However, the clinical importance of the increased TFC in AF patients has not been fully elucidated, although TFC seems to be independently associated with mean platelet volume [4], an independent risk factor for future stroke and ...

Effects of Surgical Revascularization on Cerebral Oxygen Metabolism in Patients With Moyamoya Disease: An 15O-Gas Positron Emission Tomographic Study Clinical Sciences
Conclusions— Cerebral oxygen metabolism is significantly depressed in 80% of the involved hemispheres of moyamoya disease and improves in pediatric and younger adult patients without parenchymal lesions after bypass surgery. Cerebral oxygen metabolism may be reversibly depressed in response to cerebral ischemia in them although the underlying mechanisms are still unclear.

A Case of Bilateral Giant Internal Carotid Artery Aneurysms at the Cavernous Portion Managed by 2-stage Extracranial–Intracranial Bypass with Parent Artery Occlusion: Consideration for Bypass Selection and Timing of Surgeries
In conclusion, high-flow EC-IC bypass with PAO is recommended in the first stage of surgery on a unilaterally symptomatic side to minimize postoperative hemodynamic stress to the contralateral aneurysm. Once the contralateral side becomes symptomatic, second stage EC-IC bypass with PAO, either low-flow or high-flow bypass, is recommended based on the results of balloon test occlusion.

Efficacy of Extracranial–Intracranial Bypass for Progressive Middle Cerebral Artery Occlusion Associated with Active Sjögren's Syndrome: Case Report
Sjögren syndrome affecting the major cerebral arteries is rare, and an optimal therapeutic strategy to counteract such a lesion has not yet been established. We herein report a case of a 39-year-old woman with a history of primary Sjögren syndrome, which had previously been treated with immunosuppressive therapy, manifesting with a crescendo transient ischemic attack because of left middle cerebral artery stenosis. Despite the administration of high doses of prednisolone and azathioprine for active Sjögren syndrome, the frequency of crescendo transient ischemic attacks increased with the progression of stenosis and magn...

Cognitive and Affective Disturbances Following Focal Brainstem Lesions: A Review and Report of Three Cases
Abstract Although insights in cerebellar neurocognition and affect are continuously growing, little is known about the role of the brainstem in cognitive and behavioural processing. In this paper, it is hypothesized that the brainstem is an inherent functional part of the cerebellocerebral network subserving cognition and affect, and that isolated brainstem damage may cause a constellation of symptoms closely resembling the cerebellar cognitive affective syndrome (CCAS) following cerebellar pathology. In order to investigate these premises, the available literature on cognitive and affective disturbances followin...

Dopamine transporter imaging for the diagnosis of dementia with Lewy bodies.
CONCLUSIONS: Only one study has used a neuropathological reference standard to assess the accuracy of DAT imaging for the diagnosis of DLB. The small size of the included study means that sensitivity and specificity estimates are imprecise. However, data from this study suggest that DAT imaging is more accurate than clinical diagnosis. Clinical diagnosis is therefore unsuitable to use as a reference standard for assessing the accuracy of DAT imaging.No studies using a neuropathological reference standard have directly addressed the common clinical scenario where the use of DAT imaging is considered as a diagnostic test in ...

Hemichorea in a diabetes mellitus patient following acute ischemic stroke with changes in regional cerebral blood flow
Publication date: Available online 4 March 2015 Source:Journal of the Chinese Medical Association Author(s): Yutaka Suzuki , Minoru Oishi , Akira Kanno , Katsuhiko Ogawa , Mariko Fujisawa , Satoshi Kamei It is not unusual to observe hemichorea in patients with diabetes mellitus, with origins attributable to recent ischemia. Our patient was a 66-year-old female with diabetes mellitus who suddenly developed right hemichorea, mild muscle weakness of the right upper extremity, ideational apraxia, and acalculia. Her blood glucose was 600 mg/dL, and HbA1c was 13.3%. After the patient underwent head magnetic resonance imaging ...

Neuro-Behcet's Syndrome:Case Reports Emphasizing Challenges of Early Diagnosis (P2.075)
CONCLUSIONS: In both cases, NBS was ultimately diagnosed based on characteristic MRI findings, particularly fluctuating brain stem-diencephalic involvement, superimposed on supportive clinical and CSF profiles. Challenges to early diagnosis are highlighted by our cases and by the literature. The differential diagnosis is often broad at onset. Mucocutaenous symptoms can be a clue but may not be present. Awareness of NBS and its neuroimaging correlates is critical to enable timely diagnosis, particularly given that this condition can favorably respond to steroids and steroid-sparing agents.Disclosure: Dr. Feldman has nothing to disclose.

Teaching NeuroImages: Drug-induced parkinsonism with asymmetrical putaminal DaT binding
A 64-year-old patient developed shuffling gait and postural instability over 8 months, in parallel to risperidone intake. Examination showed symmetric parkinsonian syndrome and mild left hemiparesis with spasticity, related to right middle cerebral artery stroke 10 years before. Within 1 month of risperdone withdrawal, parkinsonism disappeared, confirming drug-induced etiology. While degenerative parkinsonism is associated with reduction in striatal dopamine transporters binding in absence of structural lesions to basal ganglia, binding in drug-induced parkinsonism is normal.1 In our case, SPECT anomaly was incidental, rel...
