Filter by:The objective of this trial is to evaluate the effectiveness and safeness of personalized brain functional sectors (pBFS) technology-guided continuous theta burst stimulation (cTBS) on the inferior frontal gyrus (IFG) combined with the superior temporal gyrus (STG) for language function recovery in post-stroke aphasic patients.
The objective of this trial is to evaluate the effectiveness and safeness of intermittent Theta Burst Stimulation (iTBS) over the left Superior Temporal Gyrus (STG), guided by personalized Brain Functional Sector (pBFS) technology, on language function recovery in patients with post-ischemic stroke aphasia.

Primary progressive aphasia (PPA) is a disorder characterized by gradual decline in speech-language ability caused by underlying neurodegenerative disease. PPA is a devastating condition that can affect adults as young as their 50's, depriving them of the ability to communicate and function in society. Along with Alzheimer's Disease and other Alzheimer's Disease Related Dementias (AD/ADRD), PPA is now identified earlier and with greater precision. Increasingly, patients and families seek options for behavioral and neuromodulatory treatments to address PPA's devastating effects on communication, prolong speech-language skills, and maximize quality of life. Studies have documented the robust benefits of speech-language telerehabilitation methods for persons with PPA, with in-home treatment resulting in immediate and long-term benefits. This investigation aims to further enhance the potency of these treatment approaches by pairing them with tailored neuromodulatory intervention that targets critical brain networks supporting treatment in each clinical subtype of PPA. The study will evaluate the feasibility and preliminary benefit of home-based transcranial direct current stimulation (tDCS) combined with evidence-based speech-language telerehabilitation methods. tDCS will be delivered to patients in their own homes and site of stimulation will be tailored for each clinical subtype of PPA. This project has the potential to enhance clinical management and rehabilitation for individuals with PPA by establishing the benefit of behavioral and neuromodulatory treatment that is neurobiologically-motivated and accessible for patients and families.
Frontotemporal degeneration (FTD) is a non-Alzheimer's dementia that is the 2nd most common cause of dementia in the United States. FTD may present with focal language symptoms that are clinically described as primary progressive aphasia (PPA). There are two types of PPA associated with FTD-semantic variant primary progressive aphasia (SV-PPA) and nonfluent/agrammatic variant primary progressive aphasia (NFV-PPA). Both diseases are progressive neurodegenerative disease processes that compromise dominant hemisphere large scale brain network function, ultimately resulting in mutism. There are currently no FDA-approved treatments for PPA and management is mostly supportive. In combination with resting state functional MRI (rs-fMRI), transcranial magnetic stimulation (TMS) with intermittent theta burst stimulation (iTBS) offers a non-invasive alternative to pharmacotherapy in persons with PPA. In our prior studies of Alzheimer's disease (AD) and Lewy body Dementia (LBD) subjects, investigators have determined that the anterior temporal pole (area TGd and TGv) is an area that is commonly dysfunctional in dementia. The investigators have already embarked upon an fMRI guided study of iTBS in early stage Alzheimer's disease where subjects received a series of 5 treatments to distinct brain regions inclusive of area TGd. The investigators propose a case study of 3 PPA studies where rs-fMRI is applied to the large-scale language networks.
This study is recruiting people who had a stroke at least 1 month ago and now have a language impairment called aphasia. Living with aphasia can have devastating effects on communication and quality of life, and it is not uncommon for survivors with aphasia to face psychological problems like depression and anxiety. Participants who are eligible for this study will undergo baseline testing, engage in a 5-week treatment focused on psychological well-being, undergo post-treatment testing, and then testing again 1-month later. Check-in phone calls will be conducted during the 1-month off period and participants will be interviewed about their experience at the end of the study as well. Compensation will be provided to participants with aphasia.
Existing evidence-based treatments for word-level and sentence-level impairments following aphasia typically do not generalise to gains in everyday communication for people with aphasia (after stroke). Novel treatments need to be developed to address this. LUNA is a novel multi-level discourse treatment for people with mild to moderate aphasia that addresses personal narratives in a personalised and meta-linguistic and metacognitive manner. This is a feasibility randomised waitlist controlled trial of LUNA, in 28 people with post-stroke chronic aphasia. It will test feasibility, acceptability, preliminary efficacy, and treatment fidelity. Findings will enable the investigators to judge whether there is merit in proceeding to a larger definitive trial.
The investigators propose a pilot crossover trial of 2 behavioral language treatments, with randomized order of treatments and blinded assessors, to determine if a therapy designed to stimulate right hemisphere functions (Producing Increasingly Complex Themes Using Right-hemisphere Engagement Implemented with Telemedicine - PICTURE IT; described below) is more effective in improving discourse than a published computer delivered lexical treatment (shown previously to improve naming) in subacute post-stroke aphasia.
There are very few treatments for neurodegenerative disorders, and the efficacy of these treatments is generally modest. Recent studies have shown a short-term positive effect of non-invasive neuromodulation techniques such as transcranial magnetic stimulation (TMS) in primary progressive aphasia (PPA). PPA is a clinical syndrome associated with Alzheimer's disease and Frontotemporal degeneration. The aim of this study is to compare the effect of TMS and language therapy versus language therapy and sham TMS in patients with PPA during 6 months. A prospective, randomized, controlled, double-blind and parallel clinical trial will be conducted. The changes in brain metabolism using FDG-PET, language, neuropsychiatric symptoms, and daily-living activities will be assessed. Connectivity changes using electroencephalography will also be examined. In addition, a subgroup of patients will be assessed with multimodal MRI (structural and functional), and blood biomarkers. As a result of this project, valuable information about the long-term efficacy of non-invasive brain stimulation in PPA will be obtained, as well as the mechanisms of the therapy and clinical and neuroimaging factors associated with therapy response.
The current multi-center study aims to evaluate the efficacy and safety of pBFS-guided rTMS Neuromodulation Treatment for the rehabilitation of language functions in ischemic stroke aphasic patients.
