Neuro Device for Aphasia

Post-stroke Aphasia

The aim of the trial is to determine whether 75Hz transcranial alternating current stimulation (tACS) synchronized with therapeutic linguistic tasks is an effective form of therapy for post-stroke aphasia.

Assessing an Animal-Assisted Treatment Program for Adults With Aphasia: The Persons With Aphasia...

Aphasia

The lives of more than 2 million Americans are affected by aphasia, an acquired language impairment most commonly resulting from stroke that affects the ability to remember and express words. The well-being of these individuals is affected not just by the loss of words that is aphasia, but also the loss of friendships and opportunities for community engagement in which the loss of words can result. This study evaluates an animal-assisted treatment, The Persons with Aphasia Training Dogs (PATD) Program, designed to target the psychosocial consequences of aphasia by training participants in positive reinforcement dog training techniques that harness new skill learning and the advantages of interaction with family- or shelter-dwelling dogs to increase confidence and social engagement to support participants in living well with aphasia.

Effects of Verb Network Strengthening Treatment (VNeST) on Word Finding in Aphasia

AnomiaAphasia1 more

Although there is evidence that speech-language therapy may improve speech in language disorders following left hemisphere stroke there is still a lack of evidence for which types of therapy are effective. Furthermore, in Sweden, as well as in several other countries, access to speech-language therapy is limited. The purpose of this clinical trial is to compare outcome from Verb Network Strengthening Treatment (VNeST) provided as In-Clinic therapy (I-CT) or as synchronous telepractice therapy (TP-T).

Modulating Intensity and Dosage of Aphasia Scripts

Aphasia

The purpose of this study is to evaluate how changing conditions of speech-language treatment (namely, amount of repetition and distribution of practice schedule) affects the language outcome of participants with aphasia following a stroke. Using a computer based speech and language therapy program, participants will practice conversational scripts that are either short or long. Participants will practice for either 2 weeks (5 days a week) or for 5 weeks (2 days a week).

Effects of Electrical Stimulation on Verbal Learning in Typical and Atypical Alzheimer's Disease...

Alzheimer DiseaseEarly Onset2 more

Alzheimer's disease (AD) is the leading neurodegenerative disease of aging characterized by multiple cognitive impairments. Given the recent failures of disease-modifying drugs, the current focus is on preventing or mitigating synaptic damage that correlates with cognitive decline in AD patients. Transcranial Direct Current Stimulation (tDCS) is a safe, non-invasive, non-painful electrical stimulation of the brain that is shown to act as a primer at the synaptic level when administered along with behavioral therapy, mostly involving language, learning and memory. Previous studies have shown that tDCS over the left angular gyrus (AG) improves language associative learning in the elderly through changes in functional connectivity between the AG and the hippocampus. The investigators' previous clinical trial on the effects of tDCS in neurodegenerative disorders has also shown augmented effects of lexical retrieval for tDCS. In the present study the investigators will compare the effects of active vs. sham tDCS over the AG-an area that is part of the default mode network but also a language area, particularly important for semantic integration and event processing-in two predominant AD variants: probable AD with amnesic phenotype (amnesic/typical AD) and probable AD with non-amnesic (language deficit) phenotype also described as logopenic variant PPA with AD pathology (aphasic/atypical AD). The investigators aim to: (1) determine whether active high-definition tDCS (HD-tDCS) targeting the left AG combined with a Word-List Learning Intervention (WordLLI) will improve verbal learning; (2) identify the changes in functional connectivity between the stimulated area (AG) and other structurally and functionally connected areas using resting-state functional magnetic resonance imaging; (3) identify changes in the inhibitory neurotransmitter GABA at the stimulation site using magnetic resonance spectroscopy. Furthermore, the investigators need to determine the characteristics of the people that may benefit from the new neuromodulatory approaches. For this reason, the investigators will evaluate neural and cognitive functions as well as physiological characteristics such as sleep, and will analyze the moderating effects on verbal learning outcomes. Study results can help provide treatment alternatives as well as a better understanding of the therapeutic and neuromodulatory effects of tDCS in AD, thus improving patients' and caregivers' quality of life.

Transcranial Magnetic Stimulation and Constraint Induced Language Therapy for Chronic Aphasia

Aphasia

Transcranial Magnetic Stimulation (TMS) has been demonstrated to improve language function in subjects with chronic aphasia in a number of small studies, many of which did not include a control group. Although the treatment appears promising, data to date do not permit an adequate assessment of the utility of the technique. The investigators propose to study the effects of TMS combined with Constraint Induced Language Therapy (CILT) in 75 subjects with chronic aphasia. Subjects will be randomized in a 2:1 ratio to TMS with CILT or sham TMS with CILT. One Hz TMS at 90% motor threshold will be delivered to the right inferior frontal gyrus for 20 minutes in 10 sessions over 2 weeks; language therapy will be provided for one hour immediately after the conclusion of each session of TMS. Change from baseline in the Western Aphasia Battery Aphasia Quotient at 6 months after the end of TMS treatment will serve as the primary outcome measure. A secondary aim is to identify anatomic and behavioral predictors of response to treatment. Finally, a third aim is to identify the mechanism underlying the beneficial effect of the treatment using a variety of imaging techniques. Subjects who have no contraindication to the MRI will undergo fMRI imaging prior to and at 6 months after therapy. Using modern network analyses and robust machine learning techniques, the investigators will identify changes in the strengths of connections between nodes in the language network to address specific hypotheses regarding the effects of TMS and CILT on brain organization that are associated with beneficial response to treatment.

Incorporating Strategy Training Into Naming Treatment in Aphasia

Aphasia

This study incorporates metacognitive strategy training into semantic feature analysis treatment. Semantic feature analysis treatment has a strong evidence base and capacity to improve word retrieval by encouraging circumlocution. Circumlocution facilitates self-cued naming and assists listener comprehension when naming fails. However, semantic feature analysis treatment does not include direct techniques to teach patients with aphasia to generalize the use of semantic feature analysis treatment's circumlocution procedure. Therefore, this study proposes that combining semantic feature analysis treatment and metacognitive strategy training will stimulate the semantic system and increase patients with aphasias' use of circumlocution across divergent contexts. This study aims to measure the treatment's effect on naming accuracy for trained and untrained items. The study also aim to measure the treatment's effect on people with aphasias' knowledge of the strategy components and changes in verbalizations during retrieval attempts. The central hypothesis is that strategy training will increase patients with aphasias' explicit knowledge about circumlocution and enable them to use it to (1) self-facilitate naming, and (2) produce more informative connected speech.
