jargon aphasia

n. It is not a specific subtype of aphasia, but a term used to describe the characteristics of the language that sometimes is observed in fluent (Wernicke's) aphasias. In jargon aphasia patients' speech is abundant and easily produced, phonemes are recognizable, grammatical elements are used (and even overused), but speech contains abundant substitutions corresponding to neologisms (unrecognizable words) and paraphasias (words that are incorrect in their phonological composition - phonological paraphasias; or in their selection - verbal paraphasias), up to the point that language is completely incomprehensible to the listener. Jargon aphasia (or jargonaphasia) can be regarded as an extreme version of fluent aphasia found in usually extended left temporal or temporal-parietal lesions. Three subtypes of jargon can be distinguished, depending on the dominant substitutions: neologistic jargon, phonemic jargon, and semantic jargon, even though it is frequent to find a combination of all of them.
