The purpose of this study is to assess the effects of non-invasive brain stimulation on memory and language ability in patients with two phenotypic variations of underlying Alzheimer disease pathology: amnestic mild cognitive impairment (aMCI) and logopenic variant of primary progressive aphasia (lvPPA). This study will use repetitive Transcranial Magnetic Stimulation (rTMS) to stimulate nodes of networks that are thought to be affected in these two conditions. Specifically, a node of the Default Mode Network (DMN)-the angular gyrus (AG)-will be stimulated in aMCI patients; and a node of the language network-the posterior inferior frontal gyrus (pIFG) will be stimulated in patients with lvPPA. We will use functional connectivity MRI (fcMRI) to assess changes in functional network architecture following the stimulation. We will also assess putative cognitive improvements resulting from the stimulation by in-depth language testing in lvPPA patients and in-depth memory testing in aMCI patients.
This study proposes to use transcranial direct current stimulation (tDCS) in patients with chronic strokes and aphasia in order to characterize and enhance the mechanisms of language recovery following injury. Prior to enrollment subjects will undergo six "site-finding' sessions involving various placements of positively charged (anodal), negatively charged (cathodal), and sham stimulation over the damaged and intact hemispheres of the brain, along with standard tests of language. Subjects who are found to experience a transient improvement in language ability in this initial experiment will participate in an incomplete cross-over design study to determine if 10 sessions of tDCS stimulation lead to prolonged language benefit when delivered to the hemisphere and at the polarity shown previously to respond best to stimulation.
This study aims to evaluate the effectiveness of a therapy called High-Definition Transcranial Direct Current Stimulation (HD-tDCS) for the treatment of the language deficits experienced by people with a type of Primary Progressive Aphasia. This study uses a combination of brain imaging, language assessment, language training sessions, and HD-tDCS therapy as well as placebo therapy sessions.
People with aphasia have difficulty with writing and often struggle to use electronic communication that connects people to one another. The goal of this project is to evaluate the extent to which a novel treatment (T-WRITE) improves written language function and the use of text messaging; we also evaluate whether there are subsequent positive effects on the participant's social connectedness and ultimately health-related quality of life (HRQOL). T-WRITE involves choral reading and repeated writing of sentences via texting. Participants work intensively and independently at home on a laptop computer. A virtual therapist directs the participant to practice copying and independently writing phrases and short sentences using the typing feature on a cellular phone. The specific objective of this randomized clinical trial is to compare T-WRITE to ORLA+WTG, a similar treatment that targets written expression using handwriting.
People with Primary Progressive Aphasia (PPA) are is a debilitating disorder characterized by the gradual loss of language functioning, even though cognitive functioning is relatively well preserved until the advanced stages of the disease. There are very few evidence-based treatment options available. This study investigates the behavioral and neural effects of multiple consecutive tDCS sessions paired with language therapy targeting verbs in sentences with individuals with PPA.
Up to 40% of stroke survivors suffer from aphasia, making recovery of language abilities a top priority in stroke rehabilitation. Conventional speech and language therapy may have limited effectiveness. Leveraging multimodal data (behavioral, neuroimaging, and genetics), this study aims to 1) evaluate the efficacy of combining tDCS with speech therapy, 2) examine neural changes associated with recovery, 3) identify factors influencing response to treatment.
The present study was conducted to develop the verbal expressive skills management programme (VESMP) to enhance verbal expressive skills of patients with severe Broca aphasia. To determine the efficacy of VESMP in improving the quality of life and level of satisfaction of aphasic stroke patients.Control group received traditional therapy and experimental group received therapy through VESMP programme on their smart phones.
As aphasia is one of the most common and disabling disorders following stroke, in many cases resolving in long-term deficits, it is now thought that intensive aphasia therapy is effective, even in the chronic phase following stroke. However, as intensive aphasia rehabilitation is difficult to achieve in clinical practice, tablet-based aphasia therapies are explored to further facilitate language recovery. Although there is mounting evidence that computer-based treatments are effective, it is also important to assess the feasibility, usability and acceptability of these technologies, especially in the acute phase post stroke. The investigators assume that tablet-based aphasia therapy is a feasible treatment option for patients with aphasia in the acute phase following stroke. The researchers also believe that the specific app that will be used in therapy is user-friendly and that it will be well accepted by this specific patient population.
Post stroke aphasia (PSA) is one of the most frequently happened deficiency of stoke, affecting speaking,comprehension, writing and reading of language. Generally, PSA is commonly seen in cortical damage, but in recent years it has been found that subcortical injury is also an important cause of PSA, which is called subcortical aphasia. Using fMRI technology, the investigators aim to investigate the language function of patients with subcortical cerebral infarction at different stages of recovery , and explored the mechanism of post-injury language reorganization in the brain. The investigators recruited 60 first-episode acute cerebral infarction patients with one-side lesion in subcortical white matter (40 with left injury and 20with right injury) and 20 health volunteers. All participants are right-handed, and screened with MMSE, HAMD and HAMA to exclude cases of psychosis, post-stroke dementia and depression. Each participant was arranged to have three test sessions at different stages after the infarction (T1:within 3 days after onset of the stroke ; T2:28 ±3days after onset; T3: 90±3days after onset), with fMRI and Western aphasia battery (WAB) in each session. The purpose of this study is to explore the pathogenesis of subcortical aphasia, and to understand the dynamic reorganization of language network during the recovery of language function.
