In neurology, semantic dementia (SD), also known as semantic variant primary progressive aphasia (svPPA), is a progressive neurodegenerative disorder characterized by loss of semantic memory in both the verbal and non-verbal domains. However, the most common presenting symptoms are in the verbal domain (with loss of word meaning).

People with PPA may have difficulties comprehending what others are saying. They can also have difficulty trying to find the right words to make a sentence. [84] [85] [86] There are three classifications of Primary Progressive Aphasia : Progressive nonfluent aphasia (PNFA), Semantic Dementia (SD), and Logopenic progressive aphasia (LPA). [86] [87]
Blake Lively and Justin Baldoni aren't the first Hollywood actor-director duo to engage in on-set feuds. Will Smith and Chevy Chase infamously sparred with directors on their films.
The main subtypes of frontotemporal dementia are behavioral variant FTD (bvFTD), two variants of primary progressive aphasia – semantic dementia (svPPA) and progressive nonfluent aphasia (nfvPPA) [4] [18] – as well as FTD associated with amyotrophic lateral sclerosis (FTD–ALS or FTD-MND). [15]
