semantic paraphasia
Pronunciation: pair-ah-FAZE-ee-ah
Language error involving substitution of a semantically related word, typically seen in fluent aphasia syndromes.
Full Definition
Semantic paraphasia refers to word-finding errors where patients substitute a word that is semantically related to the intended target word, such as saying 'chair' when meaning 'table' or 'dog' when meaning 'cat'. This type of error is characteristic of fluent aphasia syndromes, particularly Wernicke's aphasia and transcortical sensory aphasia. Unlike phonemic paraphasias, semantic paraphasias preserve the phonological structure while altering the meaning. These errors reflect disruption in lexical-semantic networks and are often accompanied by relatively preserved syntax and phonology.
Usage
Usage note: Distinguish from phonemic paraphasia in clinical documentation.
