Recovery of injured Broca's portion of arcuate fasciculus in the dominant hemisphere in a patient with traumatic brain injury

  title={Recovery of injured Broca's portion of arcuate fasciculus in the dominant hemisphere in a patient with traumatic brain injury},
  author={Sung Ho Jang and Ji Wan Ha and Hyun Young Kim and You Sung Seo},
Rationale: Recovery of injured AF in patients with traumatic brain injury (TBI) has not been reported. In this study, we report on a patient with TBI who recovered from an injury to Broca's portion of AF in the dominant hemisphere, diagnosed by diffusion tensor tractography (DTT). Patient concerns: A 28-year-old right-handed male patient suffered head trauma resulting from sliding while riding a motorcycle. Diagnoses: He was diagnosed with a traumatic contusional hemorrhage in the left frontal… Expand

Although scant studies on this topic have been conducted in stroke patients, DTI for the AF appears to provide useful information on the presence or severity of injury of the AF, prognosis prediction of aphasia, and recovery mechanisms of acersia in strokes patients. Expand
Plasticity of language-related brain function during recovery from stroke.
Recovery of aphasia in adults can occur rapidly and is concomitant with an activation pattern that changes from left to a homologous right hemispheric pattern, even when the stroke evolves to completion. Expand
Characteristics of verbal impairment in closed head injured patients.
Close head injured patients with a history of coma who manifest motor speech impairment (dysarthria) also manifest linguistic processing deficits, suggesting that linguistic functions are particularly vulnerable in severe head injury. Expand
Speech disorders in closed head injury patients.
Although most patients showed an overall trend of speech improvement across time, the severely injured (Glasgow Coma Scale less than eight) continued to manifest permanent residual deficits especially those with expressive, mixed or global aphasia, and these persisted months after discharge. Expand
Evidence for Plasticity in White‐Matter Tracts of Patients with Chronic Broca's Aphasia Undergoing Intense Intonation‐based Speech Therapy
Diffusion tensor imaging (DTI) finds a significant increase in the number of AF fibers and AF volume comparing post‐ with pretreatment assessments in six patients, suggesting that intense, long‐term MIT leads to remodeling of the right AF and may provide an explanation for the sustained therapy effects.

Dynamics of language reorganization after stroke.
The data suggest that brain reorganization during language recovery proceeds in three phases: a strongly reduced activation of remaining left language areas in the acute phase is followed by an upregulation with recruitment of homologue language zones, which correlates with language improvement.

Clinical and neurophysiological findings may suggest that the AF is not required for repetition although could have a subsidiary role in it. Expand
