Remotely-supervised Neuromodulation in PPA
Recruiting now · Not applicable · Has a placebo group
Conditions studied: Primary Progressive Aphasia(PPA), Progressive Aphasia, Progressive Aphasia in Alzheimer's Disease, Logopenic Progressive Aphasia (LPA), Logopenic Variant Primary Progressive Aphasia, Logopenic Variant of Primary Progressive Aphasia (LPA)
In brief
The goal of this clinical trial is to learn whether home-based brain stimulation combined with virtual speech-language therapy can improve communication abilities in adults with logopenic variant primary progressive aphasia (lvPPA), a language disorder most often caused by Alzheimer's disease. The main questions the study aims to answer are: * Is combining remotely supervised transcranial direct current stimulation (tDCS) with virtual speech-language therapy feasible and acceptable for people with lvPPA? * Does this combined treatment lead to improvements in communication compared to speech-language therapy with sham (placebo) stimulation? * Do individual brain characteristics help predict who benefits most from this treatment? Researchers will compare participants who receive active tDCS plus virtual speech-language therapy to participants who receive sham (placebo) tDCS plus virtual speech-language therapy to see if active brain stimulation enhances communication outcomes. Participants will: * Complete speech-language therapy sessions delivered by video visit. * Receive either active or sham tDCS that is remotely supervised and completed at home. * Complete language and cognitive testing before and after treatment. * Undergo brain imaging and other assessments to help understand treatment response.
