REVIEW
Ronald M Lazar, Amelia K Boehme
PURPOSE OF REVIEW: Aphasia is a common feature of stroke, affecting 21-38% of acute stroke patients and an estimated 1 million stroke survivors. Although stroke, as a syndrome, is the leading cause of disability in the USA, less is known about the independent impact of aphasia on stroke outcomes. RECENT FINDINGS: During the acute stroke period, aphasia has been found to increase length of stay, inpatient complications, overall neurological disability, mortality, and to alter discharge disposition...

The present study addressed open questions about the nature of sentence production deficits in agrammatic aphasia. In two structural priming experiments, 13 aphasic and 13 age-matched control speakers repeated visually- and auditorily-presented prime sentences, and then used visually-presented word arrays to produce dative sentences. Experiment 1 examined whether agrammatic speakers form structural and thematic representations during sentence production, whereas Experiment 2 tested the lasting effects of structural priming in lags of two and four sentences...

OBJECTIVE: To identify implementation priorities for post-stroke aphasia management relevant to the Australian healthcare context. DATA SOURCES: Using systematized searches of databases (CINAHL, Medline), guideline and stroke websites, and other sources, evidence was identified and extracted for seven implementation criteria for 13 topic areas relevant to aphasia management. These seven priority-setting criteria were identified in the implementation literature; strength of the evidence; current evidence-practice gap; clinician preference; client preference; modifiability; measurability; and health impact...

We report the case of a 56-year-old woman who underwent total resection of a Masson's tumor or intravascular papillary endothelial hyperplasia (IPEH), which was discovered due to a left temporal intracerebral hematoma revealed by aphasia. IPEH is more often localized on cutaneous and subcutaneous locations, intracranial IPEH are rare and only approximately twenty cases have been published to date. These tumors are a benign vascular lesion composed of papillary intravascular proliferation of epithelial cellular associated thrombosis with fibrin deposits responsible for vascular lumen obliteration...

Previous studies have demonstrated that alterations of gray matter exist in post-stroke aphasia (PSA) patients. However, so far, few studies combined structural alterations of gray matter volume (GMV) and intrinsic functional connectivity (iFC) imbalances of resting-state functional MRI to investigate the mechanism underlying PSA. The present study investigated specific regions with GMV abnormality in patients with PSA (n = 17) and age- and sex- matched healthy controls (HCs, n = 20) using voxel-based morphometry...

Aphasia is a significant cause of disability and reduced quality of life. Two speech pathology treatment approaches appear efficacious: multimodal and constraint-induced aphasia therapies. In constraint-induced therapies, non-verbal actions (e.g., gesture, drawing) are believed to interfere with treatment and patients are therefore constrained to speech. In contrast, multimodal therapies employ non-verbal modalities to cue word retrieval. Given the clinical and theoretical implications, a comparison of these two divergent treatments was pursued...

Research has shown that linguistic functions in the bilingual brain are subserved by similar neural circuits as in monolinguals, but with extra-activity associated with cognitive and attentional control. Although a role for the right cerebellum in multilingual language processing has recently been acknowledged, a potential role of the left cerebellum remains largely unexplored. This paper reports the clinical and fMRI findings in a strongly right-handed (late) multilingual patient who developed differential polyglot aphasia, ataxic dysarthria and a selective decrease in executive function due to an ischemic stroke in the left cerebellum...

BACKGROUND: Progranulin gene (GRN) mutations are major causes of frontotemporal lobar degeneration. To date, 68 pathogenic GRN mutations have been identified. However, very few of these mutations have been reported in Asians. Moreover, some GRN mutations manifest with familial phenotypic heterogeneity. Here, we present a novel GRN mutation resulting in frontotemporal lobar degeneration with a distinct clinical phenotype, and we review reports of GRN mutations associated with familial phenotypic heterogeneity...

BACKGROUND: Stereotactic radiosurgery (SRS) is a widely used therapy for brain metastases(BMs) in Non-small cell lung cancer(NSCLC). However, its role in symptomatic patients with EGFR mutation remains unclear. We have retrospectively reviewed the clinical data of patients with symptomatic BMs whom received SRS as a salvage approach and concurrent gifitinib therapy. METHODS: Seven patients with primary NSCLC, symptomatic BMs, and EGFR mutation were identified in a retrospective review of patients treated with SRS using X-knife at Guangdong 999 Brain Hospital between 1 January 2012 and 31 August 2014...

Phonological complexity may be central to the nature of human language. It may shape the distribution of phonemes and phoneme sequences within languages, but also determine age of acquisition and susceptibility to loss in aphasia. We evaluated this claim using frequency statistics derived from a corpus of phonologically transcribed Italian words (phonitalia, available at phonitalia,org), rankings of phoneme age of acquisition (AoA) and rate of phoneme errors in patients with apraxia of speech (AoS) as an indication of articulatory complexity...

The aim of these two case reports is to demonstrate that a predefined, structured, multimodal clinical bed-side testing during seizures in a long-term video-EEG monitoring setting facilitates diagnosis of complex neuropsychological syndromes. To the best of our knowledge, we present the first case of conduction aphasia as the sole ictal semiology, and a patient with focal seizures producing an angular gyrus syndrome in the speech dominant hemisphere. The relevance of diagnosing ictal aphasic and angular gyrus syndromes and localizing the symptomatogenic zone is discussed...

BACKGROUND Chronic subdural hematoma (CSDH) is a common neurosurgical condition that is treated using a cranial burr hole evacuation procedure, but recurrence is common. The use of anticoagulant therapy can increase the risk of developing a recurrent subdural hematoma. We present a challenging case of a patient on long-term anticoagulant therapy following previous aortic and aortic valve surgery who had CSDH with multiple recurrences and was ultimately treated with tranexamic acid as an adjunct to surgery. CASE REPORT A male patient in his mid-sixties presented with a headache and bilateral CSDH...

INTRODUCTION: Semantic dementia, including the semantic variant of primary progressive aphasia (svPPA), is strongly associated with TAR-DNA binding protein 43 (TDP-43) type C pathology. It provides a useful model in which to test the specificity of in vivo binding of the putative tau ligand [(18)F]AV-1451, which is elevated in frontotemporal lobar degeneration tauopathies. METHODS AND RESULTS: Seven patients (five with svPPA and two with 'right' semantic dementia) and 12 healthy controls underwent positron emission tomography brain imaging with [(18)F]AV-1451...

Mario F Mendez
BACKGROUND: Few publications deal with non-neurogenic language disorders (NNLDs), distinct from psychogenic speech disorders such as psychogenic dysphonia or stuttering. NNLDs are alterations in language owing to psychosomatic preoccupations, conversion disorder, psychiatric disorders, or other psychological reasons. OBJECTIVE: To identify and classify the range of NNLDs and their characteristics. METHODS: This review summarizes the literature on disturbances in language, broadly defined as the use of symbols for communication, which may have a psychogenic or psychiatric etiology...

BACKGROUND: Brain damage can impair the use of all languages in bilingual persons. For effective management of aphasia (i.e., impaired language) in such persons, assessment of all languages is essential. The most widely used test for this purpose - the Bilingual Aphasia Test (BAT) - is cumbersome and requires a considerable amount of time for administration. To overcome this limitation, a short version of the BAT has been recommended. OBJECTIVE: The objective of this study was to derive a short version of BAT for Malayalam-English bilingual persons with aphasia and to establish the test-retest reliability as well as the content and construct validities of this version...

Diane F Morean
The majority of people with aphasia have word retrieval difficulty and effective treatment remains elusive. There have been a few studies that have explored the effects of semantic complexity on verb retrieval in individuals with aphasia; each used a variation of Breedin et al.'s (1998) delayed repetition/story completion task. Although each subsequent investigator worked to address potential confounds in order to achieve more valid results that would give rise to a clearer understanding of these deficits, findings and their interpretations have varied...

The use of a stent retriever increases the risk of intracranial vasospasm. Here, we report the case of a man who developed severe vasospasm in a long segment of the extracranial internal carotid artery after mechanical irritation by a stent retriever inserted for the treatment of acute cerebral ischemia. A 47-year-old right-handed man presented with sudden-onset right-sided weakness and difficulty speaking. The patient's National Institutes of Health Stroke Scale score was 6 and he had an Alberta Stroke Program Early Computed Tomography Score of 9...

We report the case of a patient with long-term history of hypertension, presenting with transient neurological disorders and severe graft failure several years after kidney transplantation. Cause of end-stage renal disease was hypertensive nephrosclerosis. Chronic hemodialysis lasted for 1 year. After transplantation and throughout follow-up, serum creatinine ranged from 200 to 230 μmol/L and maintenance immunosuppression included sirolimus and low-dose steroids. Six years after transplantation, the patient presented with right hip pain radiating to the lower back, transient aphasia, confusion, and hemiparesis...

Quetiapine is an atypical antipsychotic agent which is also prescribed for delirium due to its anti-dopaminergic effects; aphasia is an unusual side effect associated with the drug. Here, we report the case of an 83-year-old woman who was prescribed quetiapine (50 mg per day) for delirium. Unexpected, global aphasia occurred 3 days after treatment began. Complete recovery occurred following discontinuation of the drug. A brain computed tomography scan excluded intracranial hemorrhage and the laboratory results confirmed that no exacerbation of infection or electrolyte imbalances were present...
