Primary progressive aphasia affects one’s ability to communicate by making it difficult to express thoughts, understand words, and find words. It is a neurological syndrome that can eventually cause people to lose the ability to speak and write altogether. It comes in three types: semantic variant, logopenic variant, and nonfluent-agrammatic variant.
