(a) After a left hemisphere stroke (grey) there is recruitment of perilesional area (green). 2.1. Conclusions Post-stroke aphasia is managed with speech and language. factors like gender, age, handedness and education have not been found to be robust predictors of recovery. Background There is high variability in post-stroke aphasia severity and predicting recovery remains imprecise. Amidst a complex interaction of a multitude of variables, clinicians are faced with the arduous challenge of predicting aphasia recovery patterns and subsequently, long-term outcomes in these individuals. 2 . But a definite metric predicting the precise recovery was not available. Aphasic patients generally tend to recover with some residual deficits. Introduction. Journal of the Neurological Sciences. In aphasia, recovery is difficult to predict and evidence-based guidance on prognosis delivery is lacking. Aphasia is an inability to comprehend or formulate language because of damage to specific brain regions. Studies of aphasia recovery have evaluated people at different times post-stroke to identify variables associated with good versus poor recovery. Conclusions: Initial aphasia severity was the best predictor of early post-stroke aphasia outcome, whereas lesion measures, though highly correlated, show less influence on the prediction model. Conclusion: Factors predicting good recovery following vascular aphasia include: young age, female gender, education, absence of risk factors for stroke, localized forms of aphasia, higher grade of motor power on the paretic side, small sized hypoperfusions and absence of cerebellar diaschesis on SPECT study. Background: Prognostication is a complex clinical task that involves forming a prediction about recovery and communicating prognostic information to patients and families. Aphasia treatment is beneficial for improving functional communication and language outcomes at the group-level. Factors predicting post-stroke aphasia recovery. Objectives The outcome of aphasia at 3 months is variable in patients with moderate/severe stroke. Diagnosis Diagnostic Study of Choice Study of choice We suggest that factors predicting early recovery may differ from those involved in long-term recovery. State the two key clinical factors that predict better recovery of aphasia; Note: You will have 3 months from the date of purchase to complete and review the course material. Discuss the clinical impact of the proportional recovery model for upper limb after stroke. There were 48 participants — 22 PWA and 26 Pw/oA — all of whom were at least six months post-onset. Aphasia is an acquired impairment in language production and/or comprehension which manifests in one third of stroke survivors 1, 2, 3. Abstract. It will provide unique insights into the neurobiological basis of major psychosocial factors such as depression in post-stroke aphasia. Article Google Scholar Watila MM, Balarabe SA (2015) Factors predicting post-stroke aphasia recovery. Standard prognostics do not include neurophysiological indicators or genetic biomarkers of neuroplasticity, which may be critical sources of variability. According to the NHS, most people make some degree of recovery from aphasia, though this is more likely if it has been caused by a one-off event such as a stroke. Critically, psychosocial and treatment-related factors significantly improved model fit over lesion volume, suggesting that these factors add predictive value to determining long-term aphasia prognosis. Introduction In this talk, I will present our ongoing work aimed at predicting language recovery in monolinguals and bilingual individuals after acquired brain injury, particularly after a stroke. Amidst a complex interaction of a multitude of variables, clinicians are faced with the arduous challenge of predicting aphasia recovery patterns and subsequently, long‐term outcomes in these individuals. 5-8 Furthermore, the persistent notion that PWA experience a plateau in recovery after the first year post-stroke 9-11 has been challenged with compelling evidence suggesting that language recovery is dynamic 12-16 and . The most important factors that determine recovery are the lesion location and size, aphasia type and severity and to some extent the nature of early haemodynamic response, and treatment received.. Project 1 The goal of project 1, lead by Dr. Julius Fridriksson, is to inform the clinical management of post-stroke chronic aphasia by identifying factors that predict how an individual will respond to different treatment methods. Post-stroke aphasia severity and potential for language recovery are highly variable and difficult to predict.

DOI: 10.3109/09638288.2010.488712 Predicting outcome after stroke 123 including all patients with aphasia (not limited to achievements were discussed bi-monthly by a team patients with stroke) showed that the more aggressive of specialists . Current research on aphasia recovery has largely examined broad outcome measures such as overall aphasia severity, rather than specific aspects of speech and language (6- 14). Aphasia is among the most common and disabling consequences of stroke. WA results from lesions to the left temporoparietal region, 1-3 which supports a range of functions related to language comprehension, including auditory and phonological processing of the speech stream in the superior temporal lobe, 4-7 semantic processing of lexical information in . The duration of study was 3-4 months of the disease. Aphasia is an acquired impairment in language production and/or comprehension which manifests in one third of stroke survivors 1 - 3.Post-stroke aphasia is managed with speech and language therapy (SLT), which addresses language impairments through patient-specific, targeted training in order to improve functional communication 4, 5. . Adapted from Hamilton et al. You will receive a reminder email 2 weeks before the expiration date. 1 Introduction. Material and methods A cohort study was undertaken with 40 patients with different clinical forms of aphasia. In the present study we attempt to investigate the specifics of the association between recovery of particular language indices and possible predicting factors focusing on three language domains: speech output, comprehension and naming. Conclusions: Predicting post-stroke aphasia recovery is difficult, because of the . According to the NHS, most people make some degree of recovery from aphasia, though this is more likely if it has been caused by a one-off event such as a stroke. aphasia recovery for different language combinations outside of Spanish and English, or what factors lead to . Anagraphic factors like gender, age, handedness and education have not been found to be robust predictors of recovery. quality of life (3-5). The most important factors that determine recovery are the lesion location and size, aphasia type and severity and to some extent the nature of early haemodynamic response, and treatment received. site of lesion, cognition, including 'capacity to learn', mood and other personal characteristics), or extrinsic (e.g. It was reported to develop in one third of patients with stroke and in two thirds of patients with right hemiplegia due to stroke. The purpose of this study is to understand how the following factors influence an individual's response to aphasia treatment: 1) biographical factors (e.g., age, education, gender), 2) post-stroke cognitive/linguistic abilities and learning potential, and 3) the location and extent of post-stroke brain damage.

Machine learning reveals new factor for predicting a stroke survivor's ability to regain language skills Boston University researchers developed a machine learning model that found that the brain's resting state functional connectivity can predict how stroke survivors with aphasia recover their language skills. Wernicke's aphasia (WA) is a syndrome resulting in severe disruption to language production and comprehension. strongest of these factors.6 The degree of aphasia recovery in the acute stage has also been suggested as a possible prognostic factor. Although lateralization of the brain affects some specialized cortical functions, there are still limited data to address its influence on clinically important outcomes. Journal of Evaluation in Clinical Practice. (b) Recruitment of right perisylvian area (grey) to subserve some language function. Because both languages may benefit from therapy, identifying the optimal target language for treatment is a current challenge for research and clinical practice. Aim: To characterise the course of language recovery after first-time stroke. Conclusions Long-term aphasia recovery is multidetermined by a combination of stroke-, psychosocial-, and treatment-related factors. Earlier scientists held the opinion that factors such as size of the stroke, patient age and education, and specific characteristics of the type of language deficit can determine recovery. APHASIA A new Wellcome Trust funded study is showing that language function continues to improve over decades following stroke. Prior research has demonstrated that the BiLex computational model can accurately simulate . Rationale, aims and objectives Recovery of language function in individuals with post-stroke aphasia is associated with a variety of patient and stroke-related indices. Previous studies have demonstrated that different factors can partially or independently explain the degree of spontaneous or treatment-related language recovery after stroke.5,6 Among the most consistent predictors found in the literature are initial aphasia severity7 and For post-stroke patients, factors like size of lesion, location, and hemodynamic response can predict response to treatment. Background and Purpose The severity of aphasic impairment in chronic stroke survivors is typically thought to be stable by 6 months postonset. The investigators focused on three factors in particular — severity of stroke, impact on perceived mobility, and post-stroke environmental factors — to determine their effects on social participation in members of both groups. Some studies have reported that lesions in the superior temporal gyrus are associated with poor aphasia recovery globally or Wernicke's aphasia [ 14 , 15 ]. BY GINA MANTICA & ALEX JOHNSON The potential recovery of post-stroke aphasia is highly variable and the rehabilitation outcomes are dicult to predict. Aphasia is one of the most common acquired language deficits in patients with left hemisphere stroke.It has been reported about 24%∼48% of patients suffered aphasia in the acute stage of stroke and it remains 10%∼18% developed chronic aphasia inspite of a certain percentage of spontaneous recovery which occurs mainly during the first three months after onset. Methods: Using our Performance and Recovery in Stroke Study (PARIS . -Change in score on the Western Aphasia Battery at 3 months for stroke survivors with mild to moderate aphasia can be predicted by the following equation: •(WAB max-WAB initial ) x .73 -(WAB naming max-WAB naming initial ) x .68 -(WAB repetition max-WAB repetition initial ) x .70 -(WAB comprehension max-WAB comprehension initial ) x .83 Purpose Many factors influence poststroke language recovery, yet little is known about the influence of previous stroke(s) on language after left hemisphere stroke. New research shows that computational modeling can predict how bilingual stroke . This study aimed to reveal the prognostic variables that relate to functional recovery in stroke patients with a left-sided hemispheric lesion during 6 months of follow-up. The present study sought to determine which factors better predict early language outcomes in individuals with post-stroke aphasia. The major causes are stroke and head trauma. 2012; 18 (3):689-694; 22. •After 6 months, significant drop in rate of recovery •Unlikely for spontaneous recovery after one year, although few case reports of many years post stroke in patients undergoing SLP therapy •Copenhagen: The outcome for language function was predicted by initial severity of the aphasia and by the initial stroke severity, but not Forty-one patients with acquired aphasia due to a left single stroke were recruited. stroke. Stroke has a variable effect across patients and recovery is clearly dependent on several key factors that are either intrinsic (e.g. Predictive Models for Apraxia of Speech after Stroke; Perceptions of the Concept of "Recovery from Stroke" Aphasia Access Report on Program Effectiveness for Persons with Aphasia; Aphasia Study: Aphasia's Impact on Use of Internet and Digital Devices; Stroke Study: Factors Affecting Post-Stroke Social Participation Factors affecting recovery from aphasia after a stroke: Review of related literature: Aphasia recovery is difficult to predict, but the most powerful predictor are the lesion-related factors: Mohr et al., 14 people with chronic aphasia (5 female, mean age: 56.9 yr) Study of neurophysiology changes in two groups of aphasia treatment CIAT and ILAT In this prospective longitudinal study, we investigated the role of prior stroke on language abilities following an acute left hemisphere ischemic stroke, while controlling for demographic and stroke-related factors, and examined . Common prognostic indicators of aphasia severity include inter-related variables such as neurological (e.g., lesion size, location) and demographic (e.g., age, time post-stroke) profiles[1]. Conclusion: Factors predicting good recovery following vascular aphasia include: young age, female gender, education, absence of risk factors for stroke, localized forms of aphasia, higher grade of motor power on the paretic side, small sized hypoperfusions and absence of cerebellar diaschesis on SPECT study. Aphasia is associated with poorer performance on functional recovery 3 activities of daily living, 4 and emotional well-being after stroke. The aim of this study is to determine the relative frequency, clinical types, and prognosis of vascular aphasia in patients with acute cerebrovascular stroke. Methods Patients with post-stroke aphasia (assessed by the Aphasia Rapid Test at day 7-ART D7) and MRI performed at . 1 At stroke onset, it is not possible to predict which individuals will show substantial recovery of language and which individuals will show little recovery or even decline. Questions about aphasia prognosis commonly arise, but it is unknown how speech pathologists formulate and deliver . Post-stroke Language and Cognitive deficits; Prognosis. Figure 1: The Hierarchical model for neuroplasticity. J Neurol Sci 352:12-18 time since stroke, therapy dose and quality) to the individual. Post-stroke aphasia is a major stroke sequela and burden which significantly and negatively affects the quality of life of patients [1-4].Identifying the severity of aphasia in the early stage of stroke is crucial in predicting the prognosis of patients [5,6].However, detailed examination of post-stroke aphasia during the acute phase is often difficult because of various stroke-related . Objective To evaluate whether a common polymorphism (Val66Met) in the gene for brain-derived neurotrophic factor (BDNF . Project aims. We were specifically interested in observing changes in naming ability in early recovery (days post-stroke) and in the chronic stage (at least 6 months post-stroke). Little is known about why some individuals improve whereas others remain stable or decline . Rationale, aims and objectives Recovery of language function in individuals with post‐stroke aphasia is associated with a variety of patient and stroke‐related indices. Louise Ambridge, Alex Leff , Jenny Crinion and Cathy Price report Predicting language outcome and recovery after stroke T he acute onset of aphasia following a stroke is a traumatic and life-changing experience for The chances of recovery are . In the latest research, investigators employed Western Aphasia Battery (WAB) test . However, little is known about their implications in early spontaneous recovery. Unfortunately . (c) Right hemisphere areas (red) may be deleterious impeding functional recovery of left hemisphere area. Conclusions Predicting post-stroke aphasia recovery is difficult, because of the interplay between lesion, anagraphic, and treatment-related factors, in addition to the role of neuroplasticity.
