Low ‐frequency rTMS of the unaffected hemisphere in stroke patients: A systematic review
The aim of this review was to summarize the evidence for the effectiveness of low‐frequency (LF) repetitive transcranial magnetic stimulation (rTMS) over the unaffected hemisphere in promoting functional recovery after stroke. We performed a systematic search of the studies using LF‐rTMS over the contralesional hemisphere in stroke patients and reviewed the 67 identified articles. The studies have been gathered together according to the time interval that had elapsed between the stroke onset and the beginning of the rTMS treatment. Inhibitory rTMS of the contralesional hemisphere can induce beneficial effects on stroke...

Early Thrombectomy of a Proximal Middle Cerebral Artery Occlusion Leading to Complete Recovery with No Infarct
We report the case of a 55-year-old patient who developed sudden-onset right-sided hemiplegia and aphasia. Computed tomography angiography showed a thrombus in the M1 segment of the left middle cerebral artery. The thrombus was removed by mechanical thrombectomy 85 min after the onset of symptoms. A magnetic resonance imaging (MRI) scan showed no infarct, and the patient was discharged symptom free. To the best of our knowledge, this is the first report of thrombectomy of a symptomatic proximal middle cerebral artery occlusion leading to complete rescue, both clinically and radiologically assessed by MRI. Our case report s...

Stroke-like migraine attacks in long term survivors of high grade glioma. (P1.174)
Conclusions:Stroke-like migraine attacks are difficult to treat and the pathophysiology is unknown. With more sophisticated imaging techniques, a better understanding of this phenomenon will aid in the treatment and prophylaxis of the syndrome with a goal of improving quality of life for this small but slowly growing population.Disclosure: Dr. New has nothing to disclose.

Transcranial Direct Current Stimulation in Post-Stroke Aphasia Rehabilitation: Bilateral vs Unilateral Online Stimulation (P5.151)
Conclusions:tDCS showed to be an effective and safe tool in improving post-stroke patients’ aphasic symptoms, with no difference between the two montages employed, even if these results have to be considered preliminary, since we are still widening our sample. IFG stimulation is worth to be further explored (wider samples and evaluation for optimal stimulation parameters) as additional rehabilitative tool for post stroke aphasic patients.Disclosure: Dr. Torrente has nothing to disclose.

Characterization of Primary Progressive Aphasia and Prediction of Naming Decline by Multi-Modality MRI (N1.002)

Chronic Blood-Brain Barrier Disruption: a case report (P3.275)
Conclusions:WMH-associated BBB disruption maybe exacerbated by acute stroke, and can persist for months after the initial event, as manifest on BBB permeability imaging. These findings may offer insight into the pathophysiology of vascular dementia.Disclosure: Dr. Naqvi has nothing to disclose. Dr. Hitomi has nothing to disclose. Dr. Leigh has nothing to disclose.

Contrast induced encephalopathy mimicking reperfusion injury (P3.285)
Conclusions:Diagnostic or therapeutic angiography is frequently performed for acute ischemic or hemorrhagic stroke. Clinicians should be aware of contrast induced encephalopathy and consider it in cases of neurologic deterioration after angiography in order to initiate appropriate treatment and avoid unnecessary invasive tests.Disclosure: Dr. Bakradze has nothing to disclose.

Recurrent stroke in a patient with vitamin B12 deficiency and MTHFR mutation
We report an unusual case of recurrent stroke in a patient with vitamin B12 deficiency who was also homozygous for the methylene tetrahydrofolate reductase (MTHFR) gene mutation. The patient was a 35-year-old male vegetarian with no known medical history who initially presented with global aphasia, slurred speech, right facial weakness, and right-sided hemiplegia and was found to have a stroke (NIH Stroke Scale score of 25). At that time a CT scan of the head ruled out intracranial hemorrhage and a CT angiogram of the head and neck was done. The patient was found to have occlusion of the M1 segment of the left middle cereb...

Stroke vision, aphasia, neglect (VAN) assessment--a novel emergent large vessel occlusion screening tool: pilot study and comparison with current clinical severity indices
Conclusions The VAN screening tool accurately identified ELVO patients and outperformed a NIHSS ≥6 severity threshold and may best allow clinical teams to expedite care and mobilize resources for ELVO patients. A larger study to both validate this screening tool and compare with others is warranted.

Case Studies Demonstrating Stroke Telemedicine in the Rural Emergency Department
A 65-year-old man was transported to a critical access hospital emergency department for treatment of sudden onset dysphasia, a “funny feeling” on the right side of his face, dysphagia, and difficulty holding water in his mouth. He was alert and oriented and had unremarkable vital signs except for hypertension (188/65 mm Hg). A computed tomography scan of the head identified no abnormalities.

A Patient with Quadricuspid Aortic Valve and Ischemic Stroke.
Authors: Krisper M, Köhncke C, Escher F, Morris DA, Tschöpe C, Pieske B Abstract Quadricuspid aortic valve (QAV) is a rare congenital cardiac defect. Aortic regurgitation is the predominant hemodynamically relevant abnormality in patients with QAV, and the main reason for patients requiring valve surgery. Calcific valve disease of the left heart valves is classified as 'low embolic risk' according to current guidelines. However, it remains an important risk factor of cardiovascular events, including ischemic stroke. A 71-year-old woman presented with new-onset aphasia and hemiparesis of the right side of her body...

The unbridged gap between clinical diagnosis and contemporary research on aphasia: A short discussion on the validity and clinical utility of taxonomic categories.
Abstract Even if the traditional aphasia classification is continuously questioned by many scholars, it remains widely accepted among clinicians and included in textbooks as the gold standard. The present study aims to investigate the validity and clinical utility of this taxonomy. For this purpose, 65 left-hemisphere stroke patients were assessed and classified with respect to aphasia type based on performance on a Greek adaptation of the Boston Diagnostic Aphasia Examination. MRI and/or CT scans were obtained for each patient and lesions were identified and coded according to location. Results indicate that 26.5...

Effective ADAPT Thrombectomy in a Patient with Acute Stroke due to Cardiac Papillary Elastofibroma: Histological Thrombus Confirmation
A 75-year-old man with hypertension and atrial fibrillation was admitted to our emergency room with right-sided hemiplegia and complete aphasia (National Institutes of Health Stroke Scale [NIHSS] score  = 18). A noncontrast computed tomography scan showed a slight hypodensity in the left insular region and a bright hyperdense sign in the M1 tract of the left middle cerebral artery (MCA). Angio-CT confirmed an occlusion of the M1 tract of the MCA. Magnetic resonance diffusion-weighted imaging/p erfusion-weighted imaging was obtained and revealed a mismatch in the left parietal cortical region.
