Transferring patients with large-vessel occlusion (LVO) or intracranial hemorrhage (ICH) to hospitals not providing interventional treatment options is an unresolved medical problem.To determine how optimized prehospital management (OPM) based on use of the Los Angeles Motor Scale (LAMS) compares in a Mobile Stroke Unit (MSU) accurately triaging appropriate hospital (comprehensive stroke center [CSC]) without (primary [PSC]) treatment.In this randomized multicenter trial 3-month follow-up,...

Zusammenfassung In der neuen S2k-Leitlinie „Erster epileptischer Anfall und Epilepsien im Erwachsenenalter“ werden Empfehlungen zu klinisch relevanten Fragestellungen in fünf großen Themenblöcken gegeben: Management erster Anfall, Pharmakotherapie, Epilepsiechirurgie, komplementäre supportive Therapieverfahren psychosoziale Aspekte. Beim Thema Leitlinie zunächst zur Unterscheidung beiden maßgeblichen Differenzialdiagnosen, Synkope psychogener nicht-epileptischer gegeben. Zudem wird...

<i>Background:</i> The etiology of ischemic strokes remains cryptogenic in about one third patients, even after extensive workup specialized centers. Atherosclerotic plaques the aorta can cause thromboembolic events but are often overlooked. They elude standard identification by transesophageal echocardiography (TEE), which is invasive or at best uncomfortable for many patients. CT angiography (CTA) be used as an alternative addition to TEE if this technique fails visualize every...

<i>Background:</i> Brain imaging in stroke aims at the detection of relevant ischemic tissue pathology. Cranial computed tomography (CT) is frequently used patients with transient attack (TIA) but no data available on how it directly compares to magnetic resonance (MRI). <i>Methods: </i>We compared acute lesions CT and MRI 215 consecutive TIA who underwent brain either (n = 161) or 54). An was performed within 24 h all had initially. <i>Results:</i>...

Purpose: Specialized electroencephalography (EEG) methods have been used to provide clues about stroke features and prognosis. However, the value of routine EEG in patients without (suspected) seizures has somewhat neglected. We aimed assess this a group acute ischemic regard short-term prognosis basic features. Methods: assessed (10–20) findings 69 consecutive seizures. Associations between abnormalities NIHSS scores, clinical improvement or deterioration as well MRI characteristics were...

We aimed to evaluate ictally-induced CSF parameter changes after seizures in adult patients without acute inflammatory diseases or infectious associated with the central nervous system. In total, 151 were included study. All admitted our department of neurology following and received an extensive work-up including EEG, cerebral imaging, examinations. protein elevation was found most (92; 60.9%) significantly older age, male sex, generalized seizures. Abnormal CSF-to-serum glucose ratio only...

Prognostic clinical scores (ABCD2 and ABCD3-I), as well specific signs symptoms (e.g. fluctuations) have been used to predict early stroke risk in patients admitted hospital after transient ischemic attacks (TIAs). We compared the utility of these for prognosis outcome.235 with TIAs our Comprehensive Stroke Center entered study. Patients were monitored over 3 days detailed brain imaging [diffusion-weighted (DWI) was performed either directly on admission or within 24 h from repeated cases...

<h3>Background and Objectives</h3> Whether physical activity (PA) is a risk factor for amyotrophic lateral sclerosis (ALS) controversial because data on lifelong PA are rare. The main objective of this study to provide insight into as potential ALS, reporting cumulative PA, leisure-time occupational PA. This also aims gather evidence the role prognostic in disease course. <h3>Methods</h3> Lifetime values collected by questionnaires addressing work leisure time were quantified metabolic...

Purpose To evaluate image quality and signal characteristics of brain perfusion CT (BPCT) obtained by low-dose (LD) ultra-low-dose (ULD) protocols with without post-processing highly constrained back-projection (HYPR)–local reconstruction (LR) technique. Methods Materials Simultaneous BPCTs were acquired in 8 patients on a dual-source-CT applying LD (80 kV,200 mAs,14×1.2 mm) tube A ULD kV,30 B. Image data from both tubes was reconstructed identical parameters post-processed using the...

Since many years, clinical decisions about the management of patients with carotid stenosis have been based on distinction between “asymptomatic” and “symptomatic” presentations. This was also reflected by design previous studies surgical versus conservative treatment current interventional surgery. Both terms, however, only address different phases activity one same condition blur significant message that is a most important marker systemic atherosclerosis, which accompanied much higher...

Large artery atherosclerosis (LAA) and small vessel disease (SVD) share common risk factors for stroke. We aimed at investigating the association of SVD with cerebral LAA as well in patients stroke likely to originate from aortic plaques.We investigated 71 consecutive (48 men, mean age 64.2 ± 13 years) ischemic undetermined cause according ASCO classification, who received ECG-triggered CT angiography best available atherosclerotic plaque detection aorta.Aortic plaques were detected 54...
