Transcortical sensory aphasia is a language disorder caused by damage to the brain's language processing centers, resulting in difficulty comprehending and expressing language. This disorder is also known as sensory transcortical aphasia, receptive aphasia, or Wernicke's aphasia. Other synonyms for this condition include fluent aphasia, jargon aphasia, and receptive expressive aphasia. These terms are used interchangeably to describe a language impairment that affects a patient's ability to understand language, form thoughts and sentences, and communicate their ideas. Although the specific terms used to describe transcortical sensory aphasia may vary, they all refer to a significant communication challenge that affects many individuals who have experienced brain injury or disease.
