The research is devoted to the study of writing errors in patients with Broca’s aphasia performing the human-specific writing tasks. The object of the study is writing, the subject – disorder of writing in Broca’s agraphia. The aim of the research was to identify the most specific types of errors in writing language, depending on the cultural and historical significance of the actualized functions of writing language in Broca’s aphasia. Used instruments include classical neuropsychological assessment as well as specially developed experimental tasks aimed at actualization of cultural-historical functions of writing (communicative, mnestic and regulatory functions). Nonparametric Chi-square Friedman and Wilcoxon T-criteria used for pairwise comparison of data and analtysis of the distribution of errors. The study involved 22 patients with organic brain damage due to ischemic stroke in the basin of the left middle cerebral artery. Shown that the most specific grammatical errors were syntactic errors such as breaking of the sentence boundaries, omissions of independent and functional words, disorders of concordance and execution. Diversity in the performance of writing tasks that are similar in neuropsychological component structure but differ in functional purposes are explained by the choice of different strategies of writing. However, the general pattern is the dominance of the semantic content of the text over its formal structuring, expressed in grammatical rules. The research confirms that when studying agraphia, it is important to consider both structural (speech act operations) and functional (cultural and historical specific) aspects of writing.

Vascular Syndromes

Aphasia denotes an acquired central disorder of language, which alters patient’s ability of understanding and/or producing spoken and written language. The main cause of aphasia is represented by ischemic stroke. The language disturbances are frequently combined into aphasic syndromes, contained in different vascular syndromes, which may suffer evolution/involution in the acute stage of ischemic stroke. The main determining factor of the vascular aphasia’s form is the infarct location. Broca’s aphasia is a non-fluent aphasia, comprising a wide range of symptoms (articulatory disturbances, paraphasias, agrammatism, anomia, and discrete comprehension disorders of spoken and written language) and is considered the third most common form of acute vascular aphasia, after global and Wernicke’s aphasia. It is caused by a lesion situated in the dominant cerebral hemisphere (the left one in right-handed persons), in those cortical regions vascularized by the superior division of the left middle cerebral artery (Broca’s area, the rolandic operculum, the insular cortex, subjacent white matter, centrum semiovale, the caudate nucleus head, the putamen, and the periventricular areas). The role of this chapter is to present the most important acquirements in the field of language and neurologic examination, diagnosis, and therapy of the patient with Broca’s aphasia secondary to ischemic stroke.

Writing Errors

The research is devoted to the study of functional rearrangements in the structure of agraphia syndrome, depending on the content of the written task. Aim: To identify the variability of writing disorders in sensory and motor efferent agraphia in the conditions of performing different types of writing in terms of functional orientation. Materials and methods. The study involved 51 participants with post stroke aphasia and agraphia (29 people with with Wernicke aphasia). The severity of speech syndromes ranged from mild to moderate. All patients were right-handed. The native language for all participants was Russian. The study was carried out on the basis of inpatient departments of the Center for Speech Pathology and Neurorehabilitation in Moscow. Experimental methods included specially designed tasks that actualize the communicative, mnestic and regulatory functions of written speech. The productivity of writing when performing these tasks was compared with the assessment of the performance of diagnostic tasks traditionally used in clinical practice. Written errors were assessed at the level of individual graphemes, words and sentences. Statistical error analysis was carried out by intraindividual comparison of errors using nonparametric Chi-square tests and Wilcoxon’s test with subsequent correction for multiple comparisons using the Holm-Bonferroni method. Results. It was shown that in the group of patients with sensory agraphia, changes in the error structure were leading due to the increased load on the operation of auditory-speech analysis. In the group of patients with efferent motor dissociation agraphia identified when comparing different kinds of syntax errors. A common pattern for both groups was the use of compensatory strategies that optimize the writing process. Patients of both groups resorted to elliptical (incomplete, abbreviated) writing, used phrases of simple syntactic constructions, trying to reduce the number of written errors. The patients also resorted to a high variability of the communicative task, choosing the vocabulary that was most solidified in the past experience, which made it possible to avoid writing errors. Conclusion. Writing errors due to aphatic syndromes can be not only a manifestation of structural disorders of the component structure of speech function, but also a manifestation of the action of functional strategies of written communication.

Abstract Brodmann’s areas 44/45 of the inferior frontal gyrus (IFG), are the seat of Broca’s area. The Western Aphasia Battery is a commonly used language battery that diagnoses aphasias based on fluency, comprehension, naming and repetition. Broca’s aphasia is defined as low fluency (0-4/10), retained comprehension (4-10/10), and variable deficits in repetition (0-7.9/10) and naming (0-8/10). The purpose of this study was to find anatomic areas associated with Broca’s aphasia. Patients who underwent resective brain surgery in the dominant hemisphere were evaluated with standardized language batteries pre-op, POD 2, and 1-month post-op. The resection cavities were outlined to construct 3D-volumes of interest. These were aligned using an affine transformation to MNI brain space. A voxel-based lesion-symptom mapping (VLSM) algorithm determined areas associated with Broca’s aphasia when incorporated into a resection. Post-op MRIs were reviewed blindly and percent involvement of pars orbitalis, triangularis and opercularis was recorded. 287 patients had pre-op and POD 2 language evaluations and 178 had 1 month post-op language evaluation. 82/287 patients had IFG involvement in resections. Only 5/82 IFG resections led to Broca’s aphasia. 11/16 patients with Broca’s aphasia at POD 2 had no involvement of IFG in resection. 35% of IFG resections were associated with non-specific dysnomia and 36% were normal. By one-month, 76% of patients had normal speech. 80% of patients with Broca’s aphasia at POD 2 improved to normal speech at 1-month, with 20% improved to non-specific dysnomia. The most highly correlated (P< 0.005) anatomic areas with Broca’s aphasia were juxta-sylvian pre- and post-central gyrus extending to supramarginal gyrus. While Broca’s area resections were rarely associated with Broca’s aphasia, juxta-sylvian pre- and post-central gyri extending to the supramarginal gyrus were statistically associated with Broca’s type aphasia when resected. These results have implications for planning resective brain surgery in these presumed eloquent brain areas.

Positive Results

Agrammatism is characterized by morphosyntactic deficits in production of sentences. Studies dealing with the treatment of these deficits are scarce and their results controversial. The present study describes the rehabilitation of a case diagnosed as chronic Broca's aphasia, with agrammatism, using a method directed to sentence structural deficits. The method aims to expand the grammatical repertoire by training production of sentences with support from contexts that stimulate actions and dialogues. The patient showed positive results on all types of sentences trained and generalized the gains to spontaneous speech. However, these benefits were not sustained in the long term.
