BACKGROUND AND PURPOSE: Proximal large vessel occlusion (LVO) is present in up to 30% of minor strokes. There is no proven effectiveness of MT in the subgroup of minor stroke with LVO in the anterior circulation and data about mechanical thrombectomy (MT) in this subgroup of patients are sparse, with optimal management of these patients being yet not definitely addressed. The purpose of this case-control study was to evaluate MT in patients suffering from acute ischemic stroke (AIS) and LVO in the anterior circulation, presenting with minor to mild stroke symptoms (NIHSS<8)...

Imaging is paramount to the diagnosis and management of ischemic stroke, offering a battery of structural and functional probes of cerebrovascular physiology. The technical underpinnings of stroke imaging continue to evolve, bringing the neuroscience community increasingly closer to high-resolution, tissue-level biomarkers of brain perfusion, metabolism, and viability. The rapid expansion of neuroimaging in this domain has met with controversies, and in many respects, a lack of generalizable conclusions regarding optimized use in cerebrovascular disease...

The sudden occurrence of a focal neurological deficit, sometimes transitory and fluctuating, must lead to a suspicion of a stroke, including in a child. The preferred examination is magnetic resonance imaging with magnetic resonance angiography in an emergency. The sequelae of stroke are common and severe. Urgent diagnosis and adapted care can help to improve morbidity-mortality. Rehabilitation starts early and must systematically screen for cognitive or language impairment. The management of a stroke in a child must be planned for in multi-disciplinary protocols established before the patient's arrival at hospital...

As a result of a brain injury such as stroke, the skeletal muscles may undergo numerous structural and functional alterations. These abnormal changes are linked to muscle weakness, joint contracture, and abnormal muscle tone and eventually, result in motor impairment. A subset of these alterations affects passive muscle stiffness, i.e., viscoelastic properties. However, in vivo estimation of changes in viscoelastic properties is a challenging task. Here, we used the shear wave velocity, estimated through ultrasound SuperSonic imaging (SSI), as a surrogate for viscoelastic properties...

BACKGROUND: Basilar artery occlusion can cause locked-in syndrome, which is characterized by quadriplegia, anarthria, and limited communication via eye movements. Here, we describe an uncommon stroke syndrome associated with endovascular recanalization of the top of the basilar artery: "reverse locked-in syndrome." METHODS: We report the case of a patient with atypical neurological deficits caused by acute ischemic stroke of the midbrain tegmentum. We perform neuroanatomic localization of the patient's infarcts by mapping the magnetic resonance imaging (MRI) data onto a brainstem atlas...

This paper comments on a companion article, a first-person account of an episode of transient global amnesia written by New York Times reporter Trip Gabriel (Gabriel T. 2017. Cogn Behav Neurol. 30:1-4). Mr Gabriel describes having no memories of a cold, rainy day that he had spent on a sailboat competing in two races. The episode may have been triggered by his exposure to water. Afterward, the skipper recalled that Mr Gabriel had functioned fine on the boat, although after returning to shore he needed help finding his car...

Trip Gabriel
In this vivid first-person case history, political reporter Trip Gabriel describes experiencing a classic episode of transient global amnesia. He was near the average target age of 61. Although no cause has been established for the syndrome, as with many other patients his episode appears to have been triggered by contact with water: He was racing a sailboat. While remaining alert and handling complex sailing maneuvers, he suddenly developed amnesia that left him with no recollection of finishing two races, returning to shore, drinking a beer with his friends, needing help finding his car, and not knowing where he was or where he lived...
