Cardiac MRI Has Limited Additional Yield in Cryptogenic Stroke Evaluation (P1.225)
Conclusions: The addition of cMRI to TEE in the diagnostic evaluation of CS results in 9[percnt] reclassification of CCS subtype, with only 3[percnt] reclassified as a non-CS subtype. Our results indicate the need for cost-effectiveness studies assessing the role of cMRI in determining ischemic stroke etiology.Disclosure: Dr. Liberman has nothing to disclose.

Change in CSF Dynamics Responsible for ICP Elevation After Ischemic Stroke in Rats: a New Mechanism for Unexplained END?
AbstractIt has been proposed that intracranial pressure (ICP) elevation and collateral failure are responsible for unexplained early neurological deterioration (END) in stroke. The study ’s aims were to investigate whether cerebral spinal fluid (CSF) dynamics, rather than edema, are responsible for elevation of ICP after ischemic stroke. Permanent middle cerebral artery occlusion (pMCAO) was induced with an intraluminal filament. At 24 h after stroke, baseline ICP was measured an d CSF dynamics were probed via a steady-state infusion method. Diffusion-weighted imaging (DWI) and T2-weighted magnetic resonance imaging wer...

Chronic Apraxia of Speech and Broca's Area Clinical Sciences
Conclusions— Persistence of AOS after 12 months is associated with large left hemispheric stroke and strokes that involve Broca’s area or other relatively anterior areas to which it is structurally or functionally connected. Patients with such lesions may benefit from early training in the use of technologies to support speech production and communication.

Gastroesophageal Reflux during Enteral Feeding in Stroke Patients: A 24-hour Esophageal pH-monitoring Study
Conclusions: GER is associated with aspiration pneumonia and occurs more often in patients with stroke lesions in the left hemisphere.

Long-Term Follow-up of Incidental Intracranial Aneurysms in Patients with Acute Ischemic Stroke
Conclusions: In our study, the prevalence of incidental aneurysm among acute ischemic stroke patients was 6.1%. After 2 years of follow-up, there was no aneurysm rupture or subarachnoid hemorrhage, and the diameter and shape of aneurysms did not change except for 1 patient in whom the aneurysm disappeared.

Screening for NOTCH3 Gene Mutations Among 151 Consecutive Korean Patients with Acute Ischemic Stroke
Conclusions: In this region, NOTCH3 gene mutations are frequently found in acute stroke patients who present with neuroimaging features consistent with advanced small-vessel disease.

The Determinants of Dementia After Stroke (DEDEMAS) Study: protocol and pilot data
This study will provide insights into the mechanisms of poststroke dementia and hold the potential to identify novel diagnostic markers and targets for preventive therapies. The study is registered at http://www.clinicaltrials.gov (NCT01334749) and will be extended as a multicenter study starting 2013.

Depression: Cognition relations after stroke
ConclusionsThe rates of depression and cognitive impairment were in the range of previous stroke studies. Our study suggested a strong relation between depression and cognition characterized by executive functions and working memory dysfunctioning.

Cerebral Microbleeds as a Predictor of 1-Year Outcome of Poststroke Depression Clinical Sciences
Conclusions— The results suggest that lobar CMBs may influence the outcome of PSD. The importance of CMBs in the clinical course of depression in stroke survivors warrants further investigation.

Alpha 1-Antitrypsin Therapy Mitigated Ischemic Stroke Damage in Rats
Our objective is to develop a new therapy for the treatment of stroke. Currently, the only effective therapy for acute ischemic stroke is the thrombolytic agent recombinant tissue plasminogen activator. α1-Antitrypsin (AAT), a serine proteinase inhibitor with potent anti-inflammatory, anti-apoptotic, antimicrobial, and cytoprotective activities, could be beneficial in stroke. The goal of this study is to test whether AAT can improve ischemic stroke outcome in an established rat model. Middle cerebral artery occlusion was induced in male rats via intracranial (i.c.) microinjection of endothelin-1. Five to 10 minutes after...

Magnetic Resonance Imaging in Experimental Stroke and Comparison With Histology: Systematic Review and Meta-Analysis Basic Sciences
Conclusions— Guidelines for standardized use and reporting of MRI in preclinical stroke are urgently needed. T2-weighted imaging could be used as an effective in vivo alternative to histology for estimating treatment effects based on the extent of infarction; however, additional studies are needed to explore the effect of individual parameters.

Prevalence and cognitive impact of medial temporal atrophy in a hospital stroke service: retrospective cohort study
ConclusionsMedial temporal lobe atrophy is common and has an independent impact on cognitive function in a stroke service population, independent of confounding factors including age and magnetic resonance imaging markers of cerebrovascular disease. Medial temporal lobe atrophy is independently related to verbal memory and nominal skills, while small vessel pathology also contributes to speed and attention, and executive and perceptual functions.
