Frontotemporal degeneration (FTD) is a non-Alzheimer's dementia that is the 2nd most common cause of dementia in the United States. FTD may present with focal language symptoms that are clinically described as primary progressive aphasia (PPA). There are two types of PPA associated with FTD-semantic variant primary progressive aphasia (SV-PPA) and nonfluent/agrammatic variant primary progressive aphasia (NFV-PPA). Both diseases are progressive neurodegenerative disease processes that compromise dominant hemisphere large scale brain network function, ultimately resulting in mutism. There are currently no FDA-approved treatments for PPA and management is mostly supportive. In combination with resting state functional MRI (rs-fMRI), transcranial magnetic stimulation (TMS) with intermittent theta burst stimulation (iTBS) offers a non-invasive alternative to pharmacotherapy in persons with PPA. In our prior studies of Alzheimer's disease (AD) and Lewy body Dementia (LBD) subjects, investigators have determined that the anterior temporal pole (area TGd and TGv) is an area that is commonly dysfunctional in dementia. The investigators have already embarked upon an fMRI guided study of iTBS in early stage Alzheimer's disease where subjects received a series of 5 treatments to distinct brain regions inclusive of area TGd. The investigators propose a case study of 3 PPA studies where rs-fMRI is applied to the large-scale language networks.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Intermittent theta burst stimulation | Experimental | All subjects will receive treatment with intermittent theta burst stimulation (iTBS). There will be a total of 5 treatments over a 2-week period. All subjects will receive iTBS to the right TGd region. TBS treatment will also be provided for two additional sites within the large-scale brain networks (LSBNs) that is found to contain the greatest number of connectivity anomalies. Total participation will be 8-10 weeks. |
