OBJECTIVE: Stroke in young adults is uncommon and have rarely been described. Moyamoya disease is one of the leading causes of stroke in young adults. We aimed to study the prognostic factors for stroke recurrences and functional outcomes in young stroke patients with moyamoya disease after revascularization. METHODS: We reviewed 696 consecutive patients with moyamoya disease admitted to our hospital from 2009 to 2015 and identified patients aged 18-45 years with first-ever stroke...

Dural venous sinus thrombosis (DVST) is a rare cause of stroke, which typically affects young women. The importance of identifying pre-disposing factors that lead to venous stasis lies in the foundation of understanding the etiology, pathophysiology and clinical presentation. The precise therapeutic role of interventional therapies is not fully understood though the current data do suggest potential applications. The aim of the study was to perform a systematic review and meta-analysis to evaluate the utility of and short-term 30-day survival after endovascular therapy for patients with DVST...

Neurosarcoidosis is a rare but important cause of stroke as it is treatable. Cases reported thus far have primarily been in young people who are relatively healthy. Here we report the case of a 73-year-old woman presenting with recurrent strokes and high-grade intracranial stenosis caused by probable neurosarcoidosis. This is unique as neurosarcoidosis is not usually considered as an etiology for recurrent strokes in our patient's age-group. We review and categorize published cases of neurosarcoidosis causing stroke and describe a classification scheme for certainty of diagnosis...

BACKGROUND: Carotid sinus massage is a widely used method for diagnosis and treatment of supraventricular tachycardia and carotid sinus hypersensitivity. Complications, mostly neurological, can occur but are rare. Carotid stenosis is a risk factor for complications. Hearing a carotid bruit on auscultation indicates stenosis, and is a contraindication for performing carotid sinus massage. However, the sensitivity of auscultation is insufficient. CASE DESCRIPTION: A 71-year-old man with a history of hypertension and hypercholesterolemia presented to the cardiology accident and emergency department with palpitations...

Hemiparesis may be the result of lesions in the contralateral pyramidal tract in the brain or, less frequently, in the ipsilateral pyramidal tract in the upper cervical spinal cord. However, although rare, multiple lesions that simultaneously occur in both of these regions may be the cause of acute hemiparesis, and the clinical symptoms can often be misdiagnosed as a stroke. In addition, the correct diagnosis of these multiple central nervous system (CNS) lesions is very challenging if they are caused by infection from an unexpected microorganism...

BACKGROUND: Genetic and environmental risk factors are assumed to contribute to the susceptibility to cervical artery dissection (CeAD). To explore the role of genetic imbalance in the etiology of CeAD, copy number variants (CNVs) were identified in high-density microarrays samples from the multicenter CADISP (Cervical Artery Dissection and Ischemic Stroke Patients) study and from control subjects from the CADISP study and the German PopGen biobank. Microarray data from 833 CeAD patients and 2040 control subjects (565 subjects with ischemic stroke due to causes different from CeAD and 1475 disease-free individuals) were analyzed...

BACKGROUND AND IMPORTANCE: Lesions in the corticospinal tract above the decussation at the medullary pyramids almost universally produce contralateral deficits. Rare cases of supratentorial lesions causing ipsilateral motor deficits have been reported previously, but only ever found secondary to stroke or congenital pyramidal tract malformations. CLINICAL PRESENTATION: Herein, we report a case of ipsilateral corticospinal tract innervation discovered incidentally with intraoperative monitoring during a microsurgical resection of a vestibular schwannoma...

Ischemic strokes occur when there is a sudden obstruction of an artery supplying blood flow to an area of the brain, leading to a focal neurological deficit. Strokes can be thrombotic or embolic in etiology and are associated with underlying conditions such as hypertension and atherosclerosis. Possible etiologies of strokes include cardioembolic disease, hematologic disorders, connective tissue disorders, and substance abuse or can be cryptogenic. Most stroke cases are seen in patients over 65 years of age...

INTRODUCTION: Moyamoya disease is a progressive, chronic occlusive vascular disease of the circle of Willis arteries leading to the development of collateral circulation to compensate the occlusion. CASE REPORT: An 11-year-old girl presented an abrupt loss of consciousness and a right-sided motor deficit. Clinical examination found hypertension with 220/120mmHg arterial blood pressure. Brain magnetic resonance imaging showed a large left hemispheric ischemic lesion...

Foreign accent syndrome is a rare motor speech disorder that causes patients to speak their language with a non-native accent. In the neurogenic condition, the disorder develops after lesions in the language dominant hemisphere, often affecting Broca's area, the insula, the supplementary motor area and the primary motor cortex. Here, we present two new cases of FAS after posterior fossa lesions. The first case is a 44-year-old, right-handed, Dutch-speaking man who suffered motor speech disturbances and a left hemiplegia after a pontine infarction...

BACKGROUND: To date, sex difference in outcomes among patients with intracranial atherosclerosis (ICAS) has rarely been discussed in China as well as in the world. This study aimed to estimate the sex difference in outcomes among patients with ICAS in Chinese cerebral ischemia patients. METHODS: We analyzed 1,335 men and women with ICAS who were enrolled in the Chinese Intracranial Atherosclerosis study. They were followed-up for ischemic stroke recurrence, any cause of death, cerebral vascular events (including transient ischemic attack, ischemic and hemorrhagic stroke), combined end points (including cerebral vascular events, angina or myocardial infarction, pulmonary embolism, peripheral vascular events), and unfavorable outcome (modified Rankin scale score of 3-6) at 1 year...

Reports of involuntary ipsilateral movements after a stroke are rare, and none have described a patient with both an instinctive grasp reaction and tremor-like movement ipsilateral to the acute stroke lesion. We here report such a patient. A 76-year-old right-handed woman with a past history of left thalamic hemorrhage developed left hemiparesis, an instinctive grasp reaction, and a peculiar involuntary movement of her right arm. This involuntary movement was stereotyped and sometimes rhythmical, with a groping or picking-like action...

OBJECTIVES: To evaluate the safety and feasibility of subclavian artery stenting for coronary-subclavian steal syndrome (CSSS). BACKGROUND: CSSS is a rare cause of myocardial ischemia due to ipsilateral subclavian artery stenosis in patients who have undergone coronary artery bypass graft. However, current knowledge of the optimal therapy for CSSS is limited. METHODS: The clinical data of 37 patients (33 male; mean age 65 ± 6 years) with CSSS who had undergone subclavian artery stenting between April 2007 and December 2015 were analyzed...

Use of non-ionic contrast media (CM) in coronary arteriography has been reported to cause transient cortical blindness, confusion, amnesia and very rare focal deficits. We report a 69-year old patient with stabile angina pectoris who underwent coronary angioplasty with stent placement due to in-stent thrombosis of the right coronary artery who developed stroke symptoms with radiological suspicion of subarachnoid hemorrhage. No vascular malformations were detected on CT cerebral angiography. Dual antiplatelet treatment was continued...

An auto-inflammatory syndrome consequent to SAMHD1 mutations involves cerebral vasculopathy characterized by multifocal stenosis and aneurysms within large arteries, moyamoya, chronic ischemia, and early-onset strokes (SAMS). While this condition involves the innate immune system, additional clinical features mimic systemic lupus erythematosus. Mutations in this gene can also cause a subset of the rare genetic condition Aicardi-Goutières syndrome. To date, no established therapy successfully prevents disease progression...

Carotid artery dissection is a significant cause of ischaemic stroke in all age groups and accounts for a large percentage of strokes in young patients. Carotid dissection can be caused by trauma, underlying connective tissue disease, hypertension, mechanical injury or can be spontaneous. We present an exceedingly rare case of carotid dissection caused by an elongated styloid process, causing direct mechanical damage to the carotid artery.

BACKGROUND: Fabry disease (FD) is known as a rare cause of stroke. Recent studies suggested that FD is an underdiagnosed entity among young stroke patients. We aimed to investigate the frequency of FD in young cryptogenic stroke patients who lived in the City of Sakarya and to define the clinical features that help in recognizing patients with FD. METHODS: Acute ischemic stroke patients aged 18-55 years who were admitted to our hospital between October 2013 and September 2016 were evaluated for inclusion...

Dissecting aneurysms in the anterior cerebral artery (ACA), although rare, can cause ischemic and/or hemorrhagic stroke. Hemorrhagic dissecting aneurysms in the A1 portion of the ACA are often associated with a poor prognosis. We retrospectively investigated three rare cases of hemorrhagic dissecting aneurysms in the A1 portion. Dissecting aneurysms were diagnosed by carotid angiography or computed tomography angiography to visualize morphological changes in the vessel. All patients presented with diffuse subarachnoid hemorrhage...

Fabry disease is an important underlying disease in young cryptogenic stroke patients. However, little is known regarding the frequency of Fabry disease in the general stroke population, especially in elderly patients. A total of 588 stroke patients (61.7% men; average age 74.1±12.5 years) were enrolled in this prospective study. Blood samples were obtained to produce blood spots to determine α-galactosidase A (α-GalA) activity and for GLA gene analysis. One 65-year-old female patient had a known GLA gene mutation, c...
