Filter by:Primary Progressive Aphasia (PPA) is a syndrome due to different neurodegenerative disorders selectively disrupting language functions. PPA specialist care is underdeveloped. There are very few specialists (neurologists, psychiatrists, neuropsychologists and speech therapists) and few hospitals- or community-based services dedicated to diagnosis and continuing care. Currently, healthcare systems struggle to provide adequate coverage of diagnostic services, and care is too often fragmented, uncoordinated, and unresponsive to the needs of people with PPA and their families. Recently attention has been gained by digital-health technologies, such immunoassay analyzer and high-field MRI, the most promising approaches to increase our understanding of neurodegeneration, and by new non-invasive brain stimulation techniques such as transcranial direct current stimulation (tDCS) that allow a personalized treatment approach. Our goal is to develop a new treatment approach in PPA in which the regional secondary care centers participating in this project should be the hub of a regional network. The MAINSTREAM (WP2- Efficacy of personalized training in the early stage of PPA) looks forward to introduce and evaluate therapeutic innovation such as tDCS coupled with language therapy in rehabilitation settings (WP2 Early Treatment). This objective will be pursued by conducting a randomized controlled pilot study in order to evaluate the efficacy of a combined treatment of Active (anodal) tDCS and individualized language training compared to Placebo tDCS combined with individualized language training in a subgroup of mild PPA defined using the Progressive Aphasia Severity Scale (PASS) (Sapolsky D, Domoto-Reilly K, Dickerson BCJA. Use of the Progressive Aphasia Severity Scale (PASS) in Monitoring Speech and Language Status in PPA. (2014) 28(8-9):993-1003).
The objective of this research is to experimentally delineate the direct effect of speech entrainment practice on independent speech production and identify practice conditions that enhance treatment benefits. The primary outcome measure (Correct Information Units per minute) tallies informativeness and efficiency of independent speech in treated stories.
The overall goal of this study is to evaluate whether stimulation of two brain areas alongside behavioral speech-language therapy increases connectivity to improve language functions in stroke-aphasia patients.
Aphasia is a language disorder caused by stroke and other acquired brain injuries that affects over two million people in the United States and which interferes with life participation and quality of life. Anomia (i.e., word- finding difficulty) is a primary frustration for people with aphasia. Picture-based naming treatments for anomia are widely used in aphasia rehabilitation, but current treatment approaches do not address the long-term retention of naming abilities and do not focus on using these naming abilities in daily life. The current research aims to evaluate novel anomia treatment approaches to improve long-term retention and generalization to everyday life. This study is one of two that are part of a larger grant. This record is for sub-study 2, which will evaluate the benefits of adaptive trial spacing.

Aphasia can significantly influence a person's social relationship and quality of life. To achieve positive language outcomes, an intensive and high-repetition speech therapy is essential. However, due to the limited number of speech therapists, the intensity and frequency of training are often insufficient. Therefore, it is critical to develop other rehabilitation approaches to enhance the benefits of aphasia intervention. Virtual reality (VR) is an immersive and interactive computer simulation technology that can promote the ecological validity of speech therapy. In this study, we develop an innovative VR software for speech training to explore the effects of VR on various aspects of language outcomes.
High-Definition Transcranial Direct Current Stimulation (HD-tDCS) allows to induce, in a non-invasive way, a transient inhibitory or excitatory neuromodulation of a given cerebral region and to obtain a very focused cortical effect. Previous studies using HD-tDCS have shown the effectiveness of this stimulation technique for enhancing language recovery in patients with aphasia. However, language processes are not determined solely by local neural activity at a single site, but rather by the interaction between neural networks. This is because a large cortical network is involved in language processes and, therefore, the same language disorder may result from lesions at different locations in this network. The investigators hypothesize that anodal HD-tDCS will enhance neural interactions between language areas and, thereby, improve language processing and word learning. The investigators propose to carry out a study on chronic aphasic patients involving HD-tDCS of the Broca region (left inferior frontal gyrus) combined with a verb learning task.
The main aim of the study is to investigate the effect of a novel, speeded anomia therapy (Conroy et al., 2018) in a large population of patients with chronic post-stroke aphasia. The treatment will be delivered via a web application (QuickWord).
To investigate the intervention effect of high definition transcranial alternating current stimulation(HD-tACS) in chronic post-stroke aphasia and its underlying neural mechanism by MRI.
The efficacy of conventional speech therapy alone for aphasia recovery is inconclusive. The prospective study will monitor the effects of combined language therapy and tDCS through structural and functional MRI.
