A notable feature of aphasia in which one loses the ability to speak correctly, substitutes one word for another, and changes words and sentences in an inappropriate way. Three types of paraphasia have been described: a) Literal/Phonological Paraphasia: More than half of the intended word is produced correctly. For example, a patient may say “pun” instead of “spun.” In addition, transpositions of sounds can occur (e.g., “tevilision” for “television”). b) Neologistic Paraphasia: Less than half of the intended word is produced correctly. In some cases, the entire word is produced in correctly. Neologisms may occur in the speech of people with schizophrenia. c) verbal paraphasia: Another word is substituted for the target word. (The substitution must be a real word. If it is not, the paraphasia is classified as neologistic.)
A speech disorder in which the person uses a wrong sound in the place of the correct word or phrase.
A disorder of language in which unintended syllables, words, or phrases are interpolated in the patient’s speech. A severe degree of paraphasia results in speech that is a meaningless jumble of words and sounds, called jargon aphasia.
Misplacement of words, or use of wrong words, in speech as a result of a lesion in the speech region of the brain.
A form of aphasia in which a meaningless or inappropriate word or syllable is substituted for the correct spoken word or word combinations.
