Melodic-Intonation-Therapy and Speech-Repetition-Therapy for Patients With Non-fluent Aphasia
AphasiaStroke3 moreWe are doing this clinical trial in order to evaluate two different treatments for non-fluent aphasia: Melodic Intonation Therapy (MIT) and Speech Repetition Therapy (SRT). MIT uses a simple form of singing, while SRT uses intensive repetition of a set of words and phrases. We want to see which intensive form of treatment is more effective in leading to an improvement in speech output compared to a no-therapy control period, and whether either treatment can cause changes in brain activity during speaking and changes in brain structure. We will use a technique known as functional Magnetic Resonance Imaging (fMRI) to measure blood flow changes in the brain and structural MRI that assess brain anatomy and connections between brain regions. We will use fMRI to assess brain activity while a patient speaks, sings, and hums. We will assess changes in brain activity and in brain structure by comparing scans done prior to treatment to scans obtained after treatment and we will also examine changes between treatment groups. We will correlate changes in brain activity and brain structure with changes in language test scores.
Dopaminergic Enhancement of Learning and Memory in Aphasia
Cerebrovascular AccidentAphasiaThe purpose of this study is to determine whether levodopa, in combination with a high frequency language training, is effective in boosting naming performance in patients with aphasia.
Evaluation of the Effects of Response Elaboration Training for Aphasia
AphasiaLanguage Disorders1 moreThe purpose of this study is to evaluate the effects of Response Elaboration Training (RET), which is a speech/language therapy for aphasia. The study is designed to determine whether verbal language production improves in terms of content and length of utterances as a result of treatment.
Speech Therapy and Repetitive Transcranial Magnetic Stimulation Therapy in Post-stroke Anomic Aphasia...
AphasiaAphasia2 moreThe aim of the study is to observe the effects of speech therapy and transcranial magnetic stimulation therapy in patients who develop anomic aphasia after stroke. Patients meeting the inclusion criteria will be randomly divided into groups. In the repetitive transcranial magnetic stimulation (rTMS) treatment group, a total of 10 sessions, 1 session per day, will be applied to the right inferior frontal gyrus area with a frequency of 1 Hz for 20 minutes. The control group patients will be given speech therapy in the same way, but no active magnetic stimulation will be given in rTMS sessions (sham application). Speech therapy will be given to each patient by the same physiotherapist, and the treatment will last a total of 10 days, 60 minutes a day. Minimental test (MMT), Ege aphasia test, aphasia quality of life scale (SAQOL-39) will be filled in to the patients before and after the treatment.
Impact of Neuromodulation on Language Impairments in Stroke Patients
StrokeAphasiaUp 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.
Rehabilitating and Decelerating Language Loss in Primary Progressive Aphasia With tDCS Plus Language...
Primary Progressive AphasiaPPAPeople 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.
The Effect of Venlafaxine on Language Function in Patients With Subcortical Aphasia: A fMRI Study...
Subcortical AphasiaIschemic StrokePrevious studies have demonstrated that venlafaxine significantly improves the language function of healthy subjects and increase of fMRI activation in cortical language area. This study was designed to investigate the relationship between venlafaxine on the cortical language functional reorganization and clinical language improvements in the stroke patients with subcortical aphasia. It is a randomized, controlled, single-blind, longitudinal trial which has approved by the ethics committee of Guangzhou General Hospital of Guangzhou Military Command, and all patients and their guardian should sign an informed consent. The patients will divide into the venlafaxine group and the control group according to the principle of randomization (random number table). The patients in the venlafaxine group begin to take a venlafaxine hydrochloride capsule after enrollment ( each containing venlafaxine 75mg), qd, until 4 weeks after randomization, and the control group do not. Assessments of language functional behavior and examines of functional magnetic resonance imaging (fMRI) should be performed on the first days (V1), 28±3 days (V2) and 90±3 days (V3) after randomization. Through all this procession, we expect improve the language function of participants in experiment and clarify its mechanism,the research may help develop a new treatment for other patients with similar conditions.
Tablet-based Aphasia Therapy in the Chronic Phase
AphasiaStrokeAphasia is one of the most common and disabling disorders following stroke, in many cases resolving in long-term deficits. There is evidence that intensive aphasia therapy is effective for language recovery, even in the chronic phase post-stroke. However, as many patients are left with residual language disorders and intensive aphasia rehabilitation is difficult to achieve, the investigators are exploring tablet-based therapies to further facilitate language recovery in a cost-effective manner.
Effects of Neuromodulation on Verbal Fluency in Post-stroke Aphasia
Post-stroke AphasiaThis is a pilot study with a single active treatment arm. The study is designed to assess the efficacy of a portable, non-invasive neuromodulation system for the treatment of post-stroke aphasia. Both language and movement assessments will be made.
Transcranial Direct Current Stimulation and Aphasia Language Therapy
Nonfluent AphasiaStrokeThe purpose of this study is to evaluate the effectiveness of small amounts of electrical current, applied without surgery to the brain, in combination with speech-language treatment, on the language outcome of study subjects with nonfluent aphasia (i.e. difficulty with the comprehension and expression of spoken and written language) following a stroke.
