Queston #24180Note

There are three main types of primary progressive aphasias: logopenic, semantic, and nonfluent (also called agrammatic). Logopenic primary progressive aphasia is characterized by difficulty with word retrieval and repetition. Impaired comprehension of single words and confrontation naming is seen in semantic primary progressive aphasia, while impaired comprehension of grammatically complex sentences is impaired in non-fluent/agrammatic primary progressive aphasia.
