A Case Report of A Persian Patient with Crossed Aphasia: Agrammatism after Right Hemisphere Lesion
Crossed aphasia in dextral (CAD) refers to aphasia occurring after right brain damage in dextral persons. CAD is a rare phenomenon in the world and there has not been any report of crossed aphasia in Persian, that is why we measured to report a Persian patient with crossed aphasia and this is a first report of incidence of CA in Persian. In this case report study, we offered a complete report o...
متن کاملDissociations Between Fluency And Agrammatism In Primary Progressive Aphasia.
BACKGROUND: Classical aphasiology, based on the study of stroke sequelae, fuses speech fluency and grammatical ability. Nonfluent (Broca's) aphasia often is accompanied by agrammatism; whereas in the fluent aphasias grammatical deficits are not typical. The assumption that a similar relationship exists in primary progressive aphasia (PPA) has led to the dichotomization of this syndrome into flu...
متن کاملAdult crossed aphasia in dextrals revisited.
The clinical study of crossed aphasia in dextrals (CAD) may shed light on the discreteness and modularity of several cognitive functions, such as language, gestures and visual spatial abilities, with respect to hemispheric lateralisation. Since 1975 over 180 cases have been described, employing, however, different criteria of assessment and classification. The purpose of this paper is to review...
متن کاملLanguage processing in aphasia: changes in lateralization patterns during recovery reflect cerebral plasticity in adults.
During single word processing the negative cortical DC-potential reveals a left frontal preponderance in normal right-handers as well as in patients with a history of transient aphasia. Lateralization of DC-negativity therefore provides a reliable and robust method for the assessment of language dominance. In 11 stroke patients with permanent aphasia this physiological pattern changed to bilate...
متن کاملBrain Injury and Cerebral Lateralization
Life span studies1,2,3,4,5,6,7,8 have shown that the population percentage of left-handers diminishes steadily, so that they are drastically underrepresented in the oldest age groups. This population trend suggests the reduced longevity of left-handers9. Coren and Halpern (1991) suggest that some of the elevated risk for left-handers is apparently due to environmental factors that elevate their...
