Remotely-supervised Neuromodulation in PPA

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.

Educational Support Group Program for Bilingual and Spanish-speaking Carepartners and People With Progressive Aphasia

The current study aims to examine the benefits of an education/support group program for individuals with progressive aphasia (caused by various etiologies, diagnoses) and their carepartners. The current study utilizes pre-, post-treatment, and follow-up assessments to measure effects of a psychoeducational support group and an implementation/communication skills training phase on measures of psychosocial function, communicative effectiveness and speech/language function. Analysis of study-specific surveys and semi-structured interviews will provide qualitative data regarding outcomes. Before beginning the education and support group, focus groups will be run in order to set priorities for the themes to be included in the education program. Participants will join via tele-based means if preferred and these participants may reside in the United States, or internationally including Mexico and Spain.
