I also suspected this was the case when he was diagnosed with Aphasia in the context of not having a stroke or Brain tumor. Primary Progressive Aphasia (PPA)usually falls within the Fronto-temporal dementia (FTD) category of degenerative dementias. It is usually a tauopathy. The behavioral variant can be mistaken for a primary psychiatric disease e.g. Bipolar Disorder. I once saw a case that clinically presented as PPA that turned out to be Alzheimer’s Disease on post mortem.
