Relating resting-state hemodynamic changes to the variable language profiles in post-stroke aphasia
Publication date: Available online 21 August 2018Source: NeuroImage: ClinicalAuthor(s): Ying Zhao, Matthew A. Lambon Ralph, Ajay D. HalaiAbstractLinking both structural lesions and the functional integrity of remaining brain tissue to patients' behavioural profile may be critical in discovering the limits of behavioural recovery post stroke. In the present study, we explored the relationship between temporal hemodynamic changes and language performance in chronic post-stroke aphasia. We collected detailed language and neuropsychological data for 66 patients with chronic (>1 yr) post-stroke aphasia. We used principal comp...

Lesion mapping in acute stroke aphasia and its implications for recovery
Publication date: 1 July 2018Source: Neuropsychologia, Volume 115Author(s): Stephanie J. Forkel, Marco CataniAbstractPatients with stroke offer a unique window into understanding human brain function. Mapping stroke lesions poses several challenges due to the complexity of the lesion anatomy and the mechanisms causing local and remote disruption on brain networks. In this prospective longitudinal study, we compare standard and advanced approaches to white matter lesion mapping applied to acute stroke patients with aphasia. Eighteen patients with acute left hemisphere stroke were recruited and scanned within two weeks from ...

Crossed aphasia following cerebral infarction in a right-handed patient with atypical cerebral language dominance
ConclusionThe findings suggest that the patient has right-sided cerebral language dominance, or that both hemispheres have linguistic functions. Not all patients show linguistic capabilities on the side opposite hand preference. The language dominance should be predicted by a combination of clinical manifestations and functional imaging techniques.

Haemorrhagic stroke related to the use of 4-fluoroamphetamine
We report on two patients who presented with headache and mild hypertension after 4-FA use. Patient A developed one-sided weakness and decreased consciousness after a few hours. A computed tomography scan showed a left-sided intracerebral haemorrhage. Because of life-threatening cerebral herniation, haematoma evacuation was performed. Postoperatively, she suffered from a right-sided hemiparalysis and severe aphasia, requiring clinical rehabilitation. Patient B had a subarachnoid haemorrhage without neurological deficits. In total, 939 4-FA-intoxicated patients were registered. These patients used 4-FA alone (44%) or in com...

An Emergent Large Vessel Occlusion Screening Protocol for Acute Stroke: A Quality Improvement Initiative
Background: Nurses play an integral role in triaging stroke patients. The purpose of this quality improvement initiative was to determine the efficacy of using an emergent large vessel occlusion (ELVO) screening protocol in the emergency department by nursing staff to improve identification of eligible patients as compared with current practice, improving time to endovascular treatment. Methods: Retrospective chart review was used to identify 76 patients admitted to a large urban stroke center. Of these, 36 presented during a 4-month period before the implementation of the Stroke Vision, Aphasia, Neglect (Stroke VAN) tool ...

Interobserver agreement between senior radiology resident, neuroradiology fellow, and experienced neuroradiologist in the rating of Alberta Stroke Program Early Computed Tomography Score (ASPECTS).
CONCLUSION: ASPECTS varied among raters. However, when using a narrowed window setting for interpretation, interobserver agreement improved. PMID: 29467112 [PubMed - as supplied by publisher]

Prehospital stroke scales and large vessel occlusion: A systematic review
ConclusionsThis meta‐analysis suggests that some prehospital scoring systems including cortical signs showed better accuracy to predict stroke due to LVO. However, the assessment of these signs could be difficult to investigate by paramedics and personnel of Emergency Medical Services, and for this reason, further prospective evaluations are needed.

A severe, relapsing case of myelin oligodendrocyte glycoprotein IgG-associated CNS inflammation
A 55-year-old man presented in October 2004 with general unease, vomiting, and gait disturbance. Initially diagnosed with an inner ear infection, the patient's symptoms did not improve and he was evaluated further. MRI revealed a cerebellar lesion, which led to the suspicion of a posterior circulation stroke, and he was started on antiplatelet drugs. However, an angiogram suggested no vascular pathology. In March 2011, he had another episode of ataxia and MRI showed a right brainstem lesion. Cryptogenic stroke was reconsidered. In March 2013, the patient developed paraparesis with urinary and bowel symptoms. MRI revealed m...

Wants Talk Psychotherapy but Cannot Talk: EMDR for Post-stroke Depression with Expressive Aphasia
CONCLUSION This is the first reported case demonstrating that EMDR can be effective for depression, even in those with severe expressive aphasia. In our case, there was no reluctance to disclose information, simply a neurological inability to do so. Through preparation, patience, perseverance, and plasticity (clinician flexibility, though perhaps also neuroplasticity), the patient’s PSD gradually improved, and she was able to reinvent her life within her limitations. ACKNOWLEDGMENTS The authors gratefully acknowledge Eugene Schwartz, E.C. Hurley, and Mark Hubner for providing consultation during patient care. REFERENCES ...

Letter to the Editor: Pneumocephalus: Is the needle size significant?
Discussion. Pneumocephalus is defined by two mechanisms: a ball-valve and an inverted bottle concept.1 The ball-valve type implies positive pressure events, such as coughing or valsalva maneuvers, that prevent air escape. Tension pneumocephalus is included in this mechanism, causing a parenchymal mass effect. The inverted bottle theory includes a negative intracranial pressure gradient following cerebrospinal fluid drainage, relieved by air influx. A small pneumocephalus is usually sealed by blood clots or granulation, allowing spontaneous reabsorption and resolution.[1] Otherwise, the lateral positioning of a patient duri...

Dr. Boukrina of Kessler Foundation explores treatments for reading deficits after stroke
(Kessler Foundation) 'The Trust's funding has enabled us identify people by type of reading problem, i.e., whether their primary problem is with word appearance, word meaning, or word sounds.' Our goal is to develop criteria for identifying high-risk patients on brain scan while they are hospitalized. Fundamental to effective intervention is early identification of reading problems. 'To identify people early on, we are looking at areas of brain damage associated with aphasia and type of reading difficulties.'

A case report of parenchymal hematoma after intravenous thrombolysis in a rivaroxaban-treated patient: Is it a true rivaroxaban hemorrhagic complication?
AbstractRationale:To date, the only treatment approved for acute ischemic strokes is thrombolysis. Whether intravenous thrombolysis may be safe in patients taking direct oral anticoagulants (DOACs) is currently a matter of debate.Patient concerns:A 74-year-old woman, who was on rivaroxaban 20 mg/d for nonvalvular atrial fibrillation, was admitted to our stroke unit with left-sided hemiparesis and aphasia. The onset of neurologic deficits had occurred 5 hours after the last rivaroxaban dose.Diagnosis:An acute ischemic stroke was diagnosed.Interventions:The patient was administered thrombolytic treatment with intravenous r...

Early Rehabilitation After Stroke: a Narrative Review
AbstractPurpose of ReviewDespite current rehabilitative strategies, stroke remains a leading cause of disability in the USA. There is a window of enhanced neuroplasticity early after stroke, during which the brain ’s dynamic response to injury is heightened and rehabilitation might be particularly effective. This review summarizes the evidence of the existence of this plastic window, and the evidence regarding safety and efficacy of early rehabilitative strategies for several stroke domain-specific deficits .Recent FindingsOverall, trials of rehabilitation in the first 2  weeks after stroke are scarce. In the realm of v...
