Definition |
A disturbance of the production or comprehension of grammatical structures such as function words and word endings and in which meaning is generally preserved because of the presence of substantive words with high information content. A disturbance of the production or comprehension of grammatical structures such as function words (e.g. articles, prepositions, auxiliary verbs) and word endings (e.g. -ed, -ing). Meaning is generally preserved because of the presence of substantive words with high information content. Agrammatism is also called telegraphic speech (or telegrammatism) because of the absence of syntactical modifiers and the relative preservation of nouns, verbs, or substantive words. Agrammatism is typically associated with anterior lesions centred around the left premotor cortex and nonfluent motor aphasia.

Context |
This area includes the operculum, Broca’s third frontal gyrus, the anterior parietal area and the insula. The condition is characterized by apraxia of speech with mutism or recurring utterance, with the later emergence of agrammatism and severe reading and writing problems. Currently, therefore, the term Broca’s aphasia represents a range from the global mute condition to the agrammatic patient. More recently still, the much maligned ’faculties’ and diagrammatic schema of Lichtheim and Wernicke and others have enjoyed their own renaissance in the models of cognitive processing being developed by people working in the contemporary field of cognitive neuropsychology.
