Transcranial Magnetic Stimulation in Nonfluent/Agrammatic Variant Primary Progressive Aphasia

Primary Progressive Nonfluent Aphasia

Nonfluent/agrammatic variant primary progressive aphasia (nf/avPPA) is a fatal neurodegenerative disease that begins with isolated language deficits. There is currently no cure or treatment for this disease. Repetitive Transcranial Magnetic Stimulation (rTMS), a noninvasive neuromodulatory technique, is effective in major depression, and studied in many other conditions including nf/avPPA. Here the investigators propose to study the feasibility and change in language and brain function of a newer rTMS protocol (intermittent theta-burst stimulation, iTBS) using a randomized, blinded crossover design: participants will receive active or sham iTBS for two weeks and then switch groups without them or clinicians knowing their group. The investigators hypothesize that brain function and performance with language tasks will change after active iTBS.

Evaluating Anodal tDCS Preceding Aphasia Therapy

StrokeAphasia

The purpose of this study is to determine if non-invasive brain stimulation (transcranial direct current stimulation) delivered prior to language therapy will improve word-finding in individuals with aphasia who are 6 months or greater post-stroke.

Non-invasive Repetitive Paraorbital Alternating Current Stimulation Therapy for Aphasia

Aphasia

The investigators assess if repetitive, transcranial alternating current stimulation (rtACS) can improve the speaking quality of the aphasic patient as well as other communication skills as naming, repeating and understanding spoken words, reading and writing. Further, it will be assessed if memory and attentiveness deficiencies after 10 days of therapy with brain stimulation are stabilized and remain stable after a training-free period of 60 days.

Strategy Training for People With Aphasia After Stroke

Strategy Training

One-third to one-half of acute strokes result in newly acquired cognitive impairments. Approximately 30 to 40% of people in the acute phase of stroke also sustain communication impairments. Stroke-related cognitive impairments are associated with significant functional disability, as indicated by the inability to regain independence in daily activities. The overall aim of this study is to examine the feasibility of an adapted form of strategy training for people with communication impairments who are admitted to inpatient rehabilitation. These analyses will address a critical gap in current rehabilitation research, namely the exclusion of people with communication impairments in acute stroke rehabilitation clinical trials, and provide pilot data to inform the design of future inclusive clinical trials seeking to reduce disability after stroke.

Transcranial Direct Current Stimulation for Post-Stroke Aphasia

Stroke

This is a randomized, crossover design trial that will compare how anodal transcranial direct current stimulation (tDCS) versus sham tDCS administered during multiple sessions of scripting therapy affects the acquisition and retention of trained scripts.

Proof-of-concept Study of LUNA Intervention in Aphasia

AphasiaStroke

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.

An Evaluation of a New Nonverbal Treatment for Global Aphasia

Stroke

People with global aphasia (PwGA) post stroke have little to no meaningful communication abilities (ie limited comprehension, spoken language, reading and writing abilities).A proportion of PwGA will also have limited abilities to use any alternative means of communication e.g. gesture, pictures or computer devices. There is a suggestion in the literature that this is because of co-occurring cognitive deficits. The consequence is that these clients are unable to reliably communicate even their basic needs.This is commonly known as having no functional communication abilities. Such PwGA tend not to respond to standard speech and language therapy interventions. This research will investigate the effect of a new cognitive intervention designed to improve basic functional communication abilities. The treatment will be nonverbal and involve computer and paperbased tasks ordered hierarchically from basic to more complex tasks. Six to eight participants will take part. All their sessions will take place in their own home. For some this may be a care home. They will first complete a diagnostic communication assessment in order for baseline abilities to be established. Further formal language and cognitive assessments will be conducted over a period of 6 weeks. A relative/friend will complete a questionnaires about mood/communication. The PwGA will also be videoed interacting with the research student e.g. looking at a magazine, completing a jigsaw, answering questions and making choices non-verbally. The participants then receive the new intervention 3 times a week for 6 consecutive weeks. All intervention sessions will be videoed. Then participants will be reassessed over 2 weeks using the same assessments as prior to the intervention. The questionnaire with their relative/friend and videoed activity session will also be repeated. After a twelve week break the participant will be videoed interacting with the research student complete some of the assessments again and their relative will re-complete the questionnaires.
