Abstract Objectives: In contrast with disorders of comprehension and spontaneous expression, conduction aphasia is characterized by poor repetition, which is a hallmark of the syndrome. There are many theories on the repetition impairment of conduction aphasia. The disconnection theory suggests that a damaged in the arcuate fasciculus, which connects Broca's and Wernicke's area, is the cause of conduction aphasia. In this study, we examined the disconnection theory. Methods: We enrolled ten… 
Excellent recovery of aphasia in a patient with complete injury of the arcuate fasciculus in the dominant hemisphere.
TLDR
The possibility that aphasia might show good recovery, even in cases of severe injury of the AF, is suggested.
CORRELATION OF INJURY OF ARCUATE FASCICULUS WITH APHASIA IN PATIENTS OF MILD TBI USING DIFFUSION TENSOR IMAGING
TLDR
No correlation could be established between the FA values to the specific type of aphasia information in detecting injury of theAF and evaluation of the AF even in the case of a patient with mild TBI.
Relation between aphasia and arcuate fasciculus in chronic stroke patients
TLDR
According to the findings, the remaining volume of the left AF, irrespective of directionality and diffusivity, showed moderate positive correlation with language function in chronic stroke patients with aphasia.

TLDR
It is concluded that conduction aphasia remains a controversial topic not only from the theoretic point of view, but also from the understanding of its neurologic foundations.
Recovery of aphasia and change of injured arcuate fasciculus in the dominant hemisphere in stroke patients.
TLDR
The results suggest that facilitation of the injured AF in the dominant hemisphere could be an important strategy in neuro-rehabilitation for stroke patients with aphasia.
Changes in maps of language function and the integrity of the arcuate fasciculus after therapy for chronic aphasia
TLDR
Results provide evidence for an association between improvement in functional status and the increased integrity within a white matter tract known to be involved in language function and its contralateral homologue, as well as increased neurophysiological activity in areas that have the potential to subserve language function bilaterally.
Tractography of white matter based on diffusion tensor imaging in ischaemic stroke involving the corticospinal tract: a preliminary study
TLDR
The fractional anisotropy (FA) values and apparent diffusion coefficient (ADC) values in the ipsilesional corticospinal tract may significantly reduce comparing with the volunteer group and the stroke patient with less fiber number may bear more possibilities of better motor rehabilitation.
Injury of the Arcuate Fasciculus in the Dominant Hemisphere in Patients With Mild Traumatic Brain Injury
TLDR
DTT could provide useful information in detecting injury of theAF and evaluation of the AF using DTT would be necessary even in the case of a patient with mild TBI who complains of mild language deficit.
The Superior Longitudinal Fasciculus in Typically Developing Children and Adolescents
TLDR
Findings from this study provide an examination of the relationship between superior longitudinal fasciculus integrity and children’s neuropsychological abilities that can be useful in monitoring pediatric neurologic diseases.

TLDR
The case suggests that conduction aphasia can be caused by a lesion, though small, located in arcuate fibers of the cerebrum, and indicated that lesions in the pathway connecting Broca's area and Wernicke's area causes difficulties in selecting accurate phonemes due to a malfunctioning interface between the two areas.

Conduction aphasia and arcuate fasciculus
TLDR
Three patients are presented who developed conduction aphasia after a small infarction almost exclusively confined to the arcuate fasciculus, which shows a rapid amelioration within a week after the stroke.

Leftward asymmetry in relative fiber density of the arcuate fasciculus
TLDR
A strong asymmetry in the relative fiber density of the arcuate fasciculus is reported, a white matter pathway associated with language that connects the frontal, temporal, and parietal lobes that may provide the elements of a neural system model for language lateralization.

TLDR
DTI is sensitive to white matter injury at 3 months following moderate to severe TBI in children, including brain regions that appear normal on conventional magnetic resonance imaging.
