Active clinical trials for "Aphasia"

The purpose of this study is to investigate effects of tDCS stimulation in the left primary motor area followed by naming therapy to improve language functions in patients with aphasia in the sub-acute stage.

The refinement of repetitive transcranial magnetic stimulation (rTMS) has highlighted its merit in terms of learning programs as a treatment for aftereffect augmentation. Nevertheless, the efficacy of synchronous rTMS protocol integrated with computer-integrated speech training is not well understood. It is also not clear regarding the efficacy of compound bi-hemispheric stimulation protocol. The aim of the study is to investigate language response to these new strategies and to determine the longevity of the therapeutic outcome. Advanced MR neuroimaging techniques, such as fMRI and DTI, are powerful tools to evaluate the concomitant nervous changes after rTMS treatment on aphasic patients. The knowledge from fMRI and DTI microstructural evolution provides insight into underlined mechanism operating the language improvement.

Aphasia is one of the most disabling complications in language production in patients with left hemisphere stroke. About 19% of patients who experience aphasia may have a spontaneously recovery after several weeks or months. Some studies have reported that repetitive low frequency Transcranial Magnetic Stimulation (TMS-r) in patients with ischemic stroke generates left modulation of cortical excitability by facilitating and promoting functional reorganization and recovery of language production. In spite of this, most of the studies in patients with post-stroke aphasia, are small cases series without controls that correspond to a descriptive design and does not perform long-term follow up. Currently the population is heterogeneous respect to etiology, type of stroke and aphasia severity; also several authors have concluded that the exact location of the site, would be possible through the neuronavigation technique, to obtain better results. OVERALL OBJECTIVE Determine the efficacy of repetitive low-frequency TMS on oral language recovery in post-ischemic stroke patients with non-fluent aphasia ESPECIFIC OBJETIVES Estimate the effect of repetitiveTMS treatment on right Lowe Frontal Gyrus (GFI), in the evolution of the neuropsychological language test results in patients with non-fluent aphasia, compared to placebo. Describe the behavior of depression and anxiety levels in both treatment groups (active and placebo), through Zung anxiety and depression test, to establish their correlation with production testing language. Evaluate the effect of repetitiveTMS technique compared to placebo, on the overall functionality of the subject through Barthel scale. Describe the impact of language behavior on the quality of life of patients treated with placebo and active EMT, assessed by the EuroQol test. METHODOLOGY A placebo double blind controlled and randomize trial, to evaluate the efficacy of low frequency EMT-r in language recovery in 100 patients with first ischemic stroke event among the first 4-8 months postinfarction and non-fluent aphasia. The patient will agree and will sign the informed consent, in order to application aphasia diagnosis Boston test, Edinburgh test, Barthel scale, Zung anxiety and depression test, and EuroQol scale, Neuropsi. Subsequently the subjects will be randomizate to any of two arms of the study. A week before the start of the stimulation sessions, the following tests will be applied to assess language production: Boston Test and Verbal Fluency (FAS). Each patient will have a daily session EMT-r low-frequency active or inactive coil with a biphasic stimulator pulses applied for ten days in two weeks on the triangular area - homologous to injury Lower Front Gyrus (LFG), (right brain hemisphere). Complete the treatment schedule of two weeks, the language production will be evaluate again, and also scales as Barthel an Rankin-m, Zung anxiety and depression and EuroQol. This monitoring will be achieved in five stages: after one week, one month, 4 months, 8 months and 12 months post-stimulation, with the intention of determining the duration and effectiveness effects in language production of the EMT-r.

This prospective cohort study hypothesizes that an analysis of parallel qualitative and quantitative data is necessary to examine the full experience of living with aphasia. It is also hypothesized that there are specific factors that act as barriers or facilitators to successfully living with aphasia. A unique aspect of the project is the use of the Assessment for Living with Aphasia (ALA), a new aphasia friendly measure based on the World Health Organization International Classification of Functioning, Disability and Health (WHO ICF). Each session will assess written and spoken language, functional communication, mobility, Activities of Daily Living (ADL) function, burden of stroke, quality of life, and depression.

The purpose of this study is to determine if non-invasive electrical brain stimulation can enhance the outcome of intensive language therapy in chronic aphasia.

The purpose of this investigation is to implement a computational model that can predict and optimize training and cross-language generalization patterns for bilingual persons with aphasia (BPA). The proposed work will determine the best possible treatment program for each individual patient even before they are rehabilitated. In addition, the computational model allows specification of variables such as age of acquisition, language exposure/proficiency, impairment and their systematic influence on a range of language rehabilitation outcomes.

To study the effect of combined tDCS plus speech therapy compared to sham-tDCS plus speech therapy in subacute stroke patients suffering from moderate or severe aphasia. The patients will be randomized by a computer-generated lot. Assessment will be performed at study onset, after six weeks at the end of the specific intervention and 4 months after stroke onset for follow-up.

Aphasia is a frequent symptom after a left hemisphere stroke. It has serious impacts on social, family and professional lives. Aphasic patients need to be rehabilitated. To date, no pharmacological treatment being available only speech and language therapy (SLT) can improve patients, but its efficiency is moderate. Several studies have investigated the link between the recovery of language and neural reorganization. tDCs, a noninvasive technology for modulating neural excitability, could potentiate the effects of the SLT. About 25 studies in literature have described beneficial effects of tDCs coupled with SLT on aphasic patients. However to the investigator knowledge the feasibility of tDCs and speech therapy in clinical pathways has never been investigated. That is why the investigator propose to study in real care conditions how SLT proves more efficient on the recovery of language in a discursive assessment when coupled with active stimulation than with placebo stimulation.

This study is a pilot trial evaluating the safety and immunogenicity of AADvac1 in patients with the non-fluent variant of Primary Progressive Aphasia. 50% of participants will receive the 40 µg dosage of AADvac1 and 50% of participants will receive the 160 µg dosage of AADvac1. No placebo is used.
