Filter by:Aphasia is a loss of language due to stroke or other brain injury. Word-finding in conversation is a universal and persistent difficulty in aphasia. While several techniques exist to improve word-finding in aphasia, it is unclear how the brain changes in response to behavioral therapy. In this study, persons with aphasia will receive behavioral therapy aimed at helping them to be more successful at finding words. Twenty therapy sessions will be provided in a 10-week period. Each therapy session will last about 2 hours and will include a variety of language tasks. Prior to beginning word-finding therapy, each participant will receive two fMRI scans, spaced 10 weeks apart. After finishing therapy, each participant will receive two additional fMRI scans, spaced 10 weeks apart. For a portion of the MRI scan, participants will complete language tasks. The purpose of these fMRI scans is to measure brain changes that may occur due to successful behavioral therapy. The hypotheses are as follows: First, that the behavioral therapy will improve word-finding as it has been shown to do in the past. Second, that the brain will change in a couple of different ways. It is expected that the network of regions that support word-finding will be more connected and work together more efficiently after therapy. It is also expected that the networks of regions that support other aspects of cognitive function, such as attention and executive function, will also be more connected and work together more efficiently.
The purpose of this study is to conduct a randomized clinical trial that assesses the efficacy and cost-effectiveness of an Intensive Comprehensive Aphasia Program (ICAP), specifically focusing on the variable of intensity. Half of the participants will receive 60 hours of intensive treatment over three weeks, while the other half will receive the same amount and type of comprehensive treatment distributed over 15 weeks.
Intensive therapy for aphasia has been demonstrated to improve language functioning after stroke or other neurological injury. However, recovery is generally not complete and new therapies are needed to improve outcomes. Transcranial direct current stimulation (tDCS) has been shown to improve outcomes with motor therapy after stroke. This study will examine the feasibility of using tDCS with intensive language therapy as a way of enhancing language outcomes in aphasia
This study evaluates the verbal, cognitive, emotional, and neural efficacy of a choir singing intervention in chronic aphasic patients and their caregivers. Using a cross-over RCT design, half of the participants receive a 4-month singing intervention during the first half of the study and half of the participants during the second half of the study.
The aim of this study is to investigate the effect of dual site-dual channel non-invasive brain stimulation for recovery of language and cognitive function in post stroke patients. Simultaneous dual site-dual channel stimulation was applied by using two sets of transcranial direct current stimulation devices. All subjects will go through four conditions of transcranial direct current stimulation with for 30 minutes. Four conditions are 1) Dual stimulation: i) anodal stimulation on ipsilesional inferior frontal cortex, ii) anodal stimulation on ipsilesional dorsolateral prefrontal cortex. 2) Single stimulation 1: anodal stimulation on ipsilesional inferior frontal cortex and cathodal stimulation on contralesional inferior frontal cortex; 3) Single stimulation 2: anodal stimulation on ipsilesional inferior frontal cortex and cathodal stimulation on contralesional supraorbital area.
Combined analysis of functional and structural language network changes may be a good model for predicting language outcome.
The objective of the study is to estimate the incidence and recovery of aphasia, dysarthria and dysphagia in an acute setting (first week) with the NIHSS sub-item scores for language and speech and a dysphagia screening. Furthermore, we will evaluate the severity of aphasia, dysarthria and dysphagia in an acute setting (first few days) with standardized measurements (ScreeLing, BNT, NSVO-Z, perceptual assessment, MASA/FOIS). To evaluate the effect of early IVT/EVT in patients with ischemic stroke on functional outcomes for language and speech via the NIHSS scale.
The primary progressive aphasia (PPA) is a neurodegenerative condition characterized by a gradual, irreversible decline of language function (Mesulam, 2001). There are no known treatments for PPA so far. The relentless progression of PPA symptoms eventually leads to a profound impairment in communication ability and, ultimately, to more generalized deficits of cognition. Some cases and small studies reported that Transcranial Magnetic Stimulation (TMS), one of the non-invasive neuromodulation tech, can be employed to facilitate language production and improve the language ability in patients with PPA. Herein we will explore the tolerance and efficacy of TMS for the treatment of PPA by the randomized controlled trial .Meanwhile the functional MRI tech will be used to investigate the neural network changing in the procedure
This study was conducted in three phases: The first phase involved creation of a Spanish adaptation of the Melodic Intonation therapy; the second phase consisted of a pilot non-randomized intervention study to analyse its feasibility for use with 4 Spanish patients with poststroke nonfluent aphasia; the third phase consisted of a pilot randomised, crossover, intervention pilot trial in a different set of patients with poststroke nonfluent aphasia (N=20)
Stroke is the leading cause of adult disability in the United States, and aphasia is common following a stroke to the left hemisphere of the brain. Aphasia therapy can improve aphasia recover; however, very little is known about how different patients respond to different types of treatments. 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. We are also interested in understanding the kinds of treatment materials that should be emphasized in speech/language treatment. Overall, the goal of the current research is to inform the clinical management of post-stroke aphasia by identifying factors that can predict how an individual will respond to different treatment methods.
