People with post-stroke motor aphasia know what they would like to say but cannot express it through motor pathways due to disruption of cortical circuits. We present a theoretical background for our hypothesized connection between attention and aphasia rehabilitation and suggest why in this context, Brain-Computer Interface (BCI) use might be beneficial for patients diagnosed with aphasia. Not only could BCI technology provide a communication tool, it might support neuronal plasticity by activating language circuits and thereby boost aphasia recovery...

Spontaneous complete thrombosis of an unruptured intracranial aneurysm leading to ischemic stroke is rare. We present a case of a 56-year-old man who suffered an acute left middle cerebral artery (MCA) infarction, attributable to complete thrombosis of an unruptured saccular MCA bifurcation aneurysm with occlusion of the parent artery. The presenting hemiparesis and aphasia partially improved over a long hospital rehabilitation stay. Follow-up imaging demonstrated no recanalization of the aneurysm or parent vessels...

BACKGROUND: Atrial fibrillation and atrial flutter are atrial tachycardias associated with embolic strokes. To date, there have only been a few reports highlighting the incidence of these atrial tachycardias due to mechanical compression of myocardial structures and the pulmonary vasculature in certain mediastinal masses and cysts. CASE: We present a case of a 75-year-old gentleman who is a nonsmoker with a history of hypertension who presents with an acute embolic stroke due to atrial flutter likely from mechanical compression from an underlying squamous cell carcinoma of the lung...

Background: The language lateralization index (LI) is a valuable tool in functional magnetic resonance imaging (fMRI) research, especially in people with post-stroke aphasia. However, there is inconsistent consideration for the overlap of lesions with regions of interest (ROIs). The purpose of this study was to determine whether standard LI (SLI) and lesion-adjusted LI (LALI) formulae generate different LI values and language lateralization classification for people with post-stroke chronic aphasia. Methods: SLI and LALI were calculated for an event-related (overt) verb generation task in an anterior and a posterior language ROI...

A 39-year-old man presented with new onset right hemiparesis and aphasia within an hour of using approximately 120 mL lidocaine 4% topical solution intranasally. Lidocaine had been prescribed over a 3-week period for pain due to multiple debridements of the nasal septum. A total of 650 mL of 4% lidocaine (26 g) had been dispensed to the patient during this time. The patient had a significant history of drug abuse, including snorting crushed tablets. Otherwise he was a healthy man with no chronic diseases or conditions...

Speech and language therapy is essential in the rehabilitation of aphasic disorders following a stroke. Due to the predicted increase of aphasia and limited resources within the healthcare system, the development of efficient and sustainable treatment methods is of exceptional importance. The effectiveness of both traditional and innovative approaches needs to be evaluated against the standards of evidence-based medicine. Class I evidence has been established for high-intensity speech and language therapy in subacute and chronic stages of aphasia...

Thyroid storm is a life-threatening condition that occurs secondary to an uncontrolled hyperthyroid state. Atrial fibrillation is a cardiovascular complication occurring in up to 15% of patients experiencing thyroid storm, and if left untreated this condition could have up to a 25% mortality rate. Thyroid storm with stroke is a rare presentation. This case report details a left middle cerebral artery (MCA) stroke with global aphasia and thyroid storm in a 53-year-old Hispanic male patient. Although uncommon, this combination has been reported in multiple case series...

Here we report first 2 cases of patients with nonvalvular atrial fibrillation with acute cardioembolic stroke in whom thrombi in the left atrial appendage (LAA) were resolved by edoxaban administration. Case 1 reports an 86-year-old woman who suddenly showed right hemiparesis and aphasia due to occlusion of the left middle cerebral artery. She received mechanical thrombectomy and recovered neurologically. Transesophageal echocardiography (TEE) performed on day 1 demonstrated thrombus in the LAA. The thrombus was resolved on day 13 after initiation of edoxaban (30 mg once daily) instead of warfarin, which was administered before stroke onset...

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/perfusion-weighted imaging was obtained and revealed a mismatch in the left parietal cortical region...

Alexander Thiel, Anna Zumbansen
BACKGROUND: Post-stroke aphasia syndromes as a clinical entity arise from the disruption of brain networks specialized in language production and comprehension due to permanent focal ischemia. This approach to post-stroke aphasia is based on two pathophysiological concepts: 1) Understanding language processing in terms of distributed networks rather than language centers and 2) understanding the molecular pathophysiology of ischemic brain injury as a dynamic process beyond the direct destruction of network centers and their connections...

A growing literature is pointing towards the importance of white matter tracts in understanding the neural mechanisms of language processing, and determining the nature of language deficits and recovery patterns in aphasia. Measurements extracted from diffusion-weighted (DW) images provide comprehensive in vivo measures of local microstructural properties of fiber pathways. In the current study, we compared microstructural properties of major white matter tracts implicated in language processing in each hemisphere (these included arcuate fasciculus (AF), superior longitudinal fasciculus (SLF), inferior longitudinal fasciculus (ILF), inferior frontal-occipital fasciculus (IFOF), uncinate fasciculus (UF), and corpus callosum (CC), and corticospinal tract (CST) for control purposes) between individuals with aphasia and healthy controls and investigated the relationship between these neural indices and language deficits...

BACKGROUND: Patients with basilar migraine (BM) and hemiplegic migraine (HM) have been excluded from triptan and DHE clinical trials due to a potential risk of ischemic vascular events, and the FDA mandates that package labeling state that they are contraindicated in BM and HM. The objective of this study was to demonstrate that triptans and DHE can be used for the abortive treatment of BM and HM without significant adverse ischemic vascular events. METHODS: A retrospective chart review of patients with BM features or HM who received acute abortive treatment with either triptans or DHE was conducted at 4 headache centers to assess the frequency of ischemic vascular events after administration...

RANDOMIZED CONTROLLED TRIAL
Marcus Meinzer, Robert Darkow, Robert Lindenberg, Agnes Flöel
Transcranial direct current stimulation has shown promise to improve recovery in patients with post-stroke aphasia, but previous studies have only assessed stimulation effects on impairment parameters, and evidence for long-term maintenance of transcranial direct current stimulation effects from randomized, controlled trials is lacking. Moreover, due to the variability of lesions and functional language network reorganization after stroke, recent studies have used advanced functional imaging or current modelling to determine optimal stimulation sites in individual patients...

BACKGROUND: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is considered a common cause of hereditary stroke caused by mutation of the NOTCH3 gene. Evidence against the use of intravenous tissue plasminogen activator (IV tPA) has been suggested due to possibility of hemorrhage. We present a case of a patient with CADASIL who was successfully treated using IV tPA. METHODS: A case description of a female patient who presented with stroke-like symptoms was a previously known case of CADASIL...
