According to Western Aphasia Battery (Kertesz 1982) aphasia is classified as non-fluent aphasias, including global, Broca’s, isolation and transcortical motor aphasias, and as fluent aphasias, including Wernicke’s, transcortical sensory, conduction and anomic aphasias.
Among the aphasia types global aphasia has the poorest prognosis, Broca’s aphasics often recovering towards anomic aphasia, and Wernicke’s aphasics tending to recover towards anomic or conduction aphasias.

Receptive aphasia, also known as Wernicke's aphasia, fluent aphasia, or sensory aphasia in clinical neuropsychology and cognitive neuropsychology, is a type of aphasia often (but not always) caused by neurological damage to Wernicke's area in the brain (Brodman Area 22, in the posterior part of the superior temporal gyrus of the dominant hemisphere).
Patients who recover from Wernicke's aphasia report that while aphasic they found the speech of others to be unintelligible, and even though they knew they were speaking, they could neither stop themselves nor understand what they had just said.

The WAB furthermore provides a calculated metric of overall aphasia severity, known as the Aphasia Quotient (AQ), which ranges from 0-100, and it assigns persons with aphasia to one of eight diagnostic categories, such as global aphasia, Broca's aphasia, Wernicke's aphasia, anomic aphasia, etc., based on patients' patterns of impairments and residual capabilities.
Of the eighteen chronic patients assigned to Broca's aphasia by the WAB before treatment, five were reassigned by the WAB after treatment to the less severe aphasia diagnostic category of conduction aphasia, with an average AQ improvement of +20.2 points.

 Custom essay on Health / Aphasia Conduction Aphasia - Essay Empire
As indicated by the preceding description of conduction aphasia, impaired repetition is often considered of prime importance for identifying this syndrome.
(1977) presented a possible solution to this issue by distinguishing "repetition conduction aphasia" and "reproduction conduction aphasia." They argued that a deficit in auditory-verbal short-term memory was responsible for impaired repetition in some conduction aphasics and that an independent deficit in speech programming was responsible for the paraphasic output in other conduction aphasics.
This latter decision does not rule out the presence of impaired repetition in conduction aphasia, but merely specifies that output based on other input modalities must also be impaired in conduction aphasia.

If one follows the standard clinical description of conduction aphasia as a disturbance in repetition that is paired with relatively preserved spontaneous speech and auditory comprehension, a heterogeneous group of patients will result.
At this level, the possible underlying deficits responsible for conduction aphasia are so varied as to render this syndrome of little use at both the clinical and experimental level.
