agrammatism
Pronunciation: ay-GRAM-uh-tizm
Language disorder characterized by the loss of ability to construct grammatically correct sentences, typically affecting syntax and word order.
Full Definition
Agrammatism is a specific type of aphasia where patients lose the ability to use grammar properly in speech and writing. This condition commonly affects Broca's area and results in telegraphic speech with preserved nouns and verbs but missing function words like articles, prepositions, and conjunctions. The condition is frequently observed in stroke patients and those with frontotemporal dementia. Editors should note that agrammatism is distinct from dysarthria, which affects speech motor control rather than language structure.
Usage
Usage note: Do not confuse with dysarthria (motor speech disorder) or general word-finding difficulties.
