Transcortical Sensory Aphasia
Transcortical sensory aphasia is a subtype of fluent aphasia in which repetition is preserved and auditory comprehension and verbal expression are impaired. Extemporaneous speech is fluent and effortless, with intact grammar and prosody and frequent paraphasic errors.
Transcortical sensory aphasia is a subtype of fluent aphasia, differentiated from other fluent aphasia types by the patient’s preserved ability to repeat words and phrases, relative to their impaired comprehension and paraphasic output.
Natural History, Prognostic Factors, and Outcomes
Transcortical aphasias are relatively rare, occurring in less than 10% of patients with stroke (Bakheit et al. 2007; Laska et al. 2001). When a patient presents with transcortical aphasia after stroke, recovery tends to be rapid. For nonvascular disorders, the prognosis depends on the etiology as well as predictors of outcome in general, such as comorbid conditions, age, and lesion size.
