In between Carl Wernicke's locationist aphasia concept from 1874 and Norman Geschwind's new connectionist model of human brain functions in 1965, little notice was taken of the historical debate on aphasia and brain plasticity. Interestingly, Kurt Goldstein made long-forgotten, but highly relevant remarks on the connectionist model and thereby served as an important connecting link between Wernicke and Geschwind. With the original contributions of Goldstein and contemporary authors, we analyzed the historical background of the aphasia debate in the time period between Wernicke and Geschwind, which still influences current aphasia concepts and neurosurgical practice of today...

BACKGROUND: The underlying mechanism of transcortical sensory aphasia (TSA) caused by lesions occurring in the left frontal lobe remains unclear. We attempted to investigate the mechanism with the use of functional MRI (fMRI). METHODS: We studied 2 patients with TSA after a left frontal infarction identified by diffusion-weighted MRI. As control subjects, a patient with transcortical motor aphasia and a healthy normal adult were chosen. The Korean version of Western Aphasia Battery was performed initially and at 3 months post stroke...

Background Comorbidities and complications of stroke have implications for level of care and hospital resources. It is critical, therefore, that hospital morbidity data accurately reflect the prevalence of these additional diagnoses. Objective This study aimed to measure and describe the concordance between stroke clinicians/researchers and medical record coders when recording stroke and related diagnoses. Method Diagnoses recorded prospectively, according to defined criteria by a clinical research team, were compared with the coding of stroke comorbidities and complications as per the Australian Coding Standards (ACS) from the separations of 100 inpatients from three rehabilitation facilities in South Australia...

Communicative gestures can compensate incomprehensibility of oral speech in severe aphasia, but the brain damage that causes aphasia may also have an impact on the production of gestures. We compared the comprehensibility of gestural communication of persons with severe aphasia and non-aphasic persons and used voxel based lesion symptom mapping (VLSM) to determine lesion sites that are responsible for poor gestural expression in aphasia. On group level, persons with aphasia conveyed more information via gestures than controls indicating a compensatory use of gestures in persons with severe aphasia...

Alfredo Ardila, Silvia Rubio-Bruno
The purpose of this study was to analyze the question: how do people with aphasia experience the world? Three questions are approached: (1) how is behavior controlled in aphasia, considering that a normal linguistic control is no longer available; (2) what is the pattern of intellectual abilities in aphasia; and (3) what do aphasia patients' self-report regarding the experience of living without language. In aphasia, behavior can no longer be controlled through the "second signal system" and only the first signal system remains...

REVIEW
Cyril Hazif-Thomas, Philippe Thomas
Alzheimer's disease is accompanied by gradual aphasia, becoming more severe when the cognitive disorders are more marked. However, the quality of care provided to the patient can modulate the evolution of these language difficulties. Aphasia is linked to a human communication deficiency and can be limited by taking into account the phatic function of language to keep the channels of communication open.

Reading impairment is an important feature in Primary Progressive Aphasia (PPA). The Spanish orthography entails completely regular spelling to sound correspondences, so reading disorders may be different to English. In the current study, reading, phonological and semantic abilities of 35 patients with the three variants of PPA, and 13 healthy volunteers were assessed. Brain metabolism was concomitantly obtained from each participant using (18)F-fluorodeoxyglucose positron emission tomography imaging. Two main patterns of impairment were identified: difficulties in nonwords reading with preservation of exception words in agrammatic and logopenic aphasia, and the inverse pattern in semantic dementia...

BACKGROUND: Individuals with aphasia are often excluded from studies exploring poststroke cognition because so many of the standard cognitive assessments rely on language ability. Our primary objective was to examine the association between performance on cognitive tests and performance on comprehension and naming tests in poststroke aphasia. Second, we aimed to determine the association between language performance and a real-life measure of cognition (Kettle Test). Third, we explored the feasibility of administering cognitive tests in aphasia...

BACKGROUND: Papillary fibroelastoma is the third most common primary benign tumor with an incidence of up to 0.33% in autopsy series; it accounts for approximately 75% of all cardiac valvular tumors. CASE PRESENTATION: We describe a rare case of a 28-Year-old man that while playing football, had a sudden onset of neurological deficit: aphasia, right hemiparesis and right facial numbness. Transthoracic echocardiography (TTE) showed a 10x10 mm mass attached to the anterior mitral valve leaflet...

Behavioural impairment post-stroke is a consequence of structural damage and altered functional network dynamics. Hypoperfusion of intact neural tissue is frequently observed in acute stroke, indicating reduced functional capacity of regions outside the lesion. However, cerebral blood flow (CBF) is rarely investigated in chronic stroke. This study investigated CBF in individuals with chronic Wernicke's aphasia (WA) and examined the relationship between lesion, CBF and neuropsychological impairment. Arterial spin labelling CBF imaging and structural MRIs were collected in 12 individuals with chronic WA and 13 age-matched control participants...

This study examined patterns of neologistic and perseverative errors during word repetition in fluent Jargon aphasia. The principal hypotheses accounting for Jargon production indicate that poor activation of a target stimulus leads to weakly activated target phoneme segments, which are outcompeted at the phonological encoding level. Voxel-lesion symptom mapping studies of word repetition errors suggest a breakdown in the translation from auditory-phonological analysis to motor activation. Behavioral analyses of repetition data were used to analyse the target relatedness (Phonological Overlap Index: POI) of neologistic errors and patterns of perseveration in 25 individuals with Jargon aphasia...

Purpose: Language comprehension in people with aphasia (PWA) is frequently evaluated using multiple-choice displays: PWA are asked to choose the image that best corresponds to the verbal stimulus in a display. When a nontarget image is selected, comprehension failure is assumed. However, stimulus-driven factors unrelated to linguistic comprehension may influence performance. In this study we explore the influence of physical image characteristics of multiple-choice image displays on visual attention allocation by PWA...

OBJECTIVE: To determine whether logopenic features of phonologic loop dysfunction reflect Alzheimer disease (AD) neuropathology in primary progressive aphasia (PPA). METHODS: We performed a retrospective case-control study of 34 patients with PPA with available autopsy tissue. We compared baseline and longitudinal clinical features in patients with primary AD neuropathology to those with primary non-AD pathologies. We analyzed regional neuroanatomic disease burden in pathology-defined groups using postmortem neuropathologic data...

BACKGROUND AND PURPOSE: To determine the clinical utility of the midbrain-to-pons (M/P) ratio as a clinical biomarker of progressive supranuclear palsy (PSP) in patients with non-fluent primary progressive aphasia syndromes. METHODS: Patients with PSP, progressive non-fluent aphasia (PNFA) and logopenic progressive aphasia (LPA) were recruited. Patients were diagnosed clinically, but pathological confirmation was available in a proportion of patients. Midbrain and pons areas were measured using Osirix Lite, a free DICOM viewer...
