Which type of aphasia is associated with the poorest prognosis?
Global/severe aphasia
In individuals with global aphasia, this most likely to improve are those with…
- lesions that are mainly subcortical
- an absence of damage to Wernicke’s area
- and an early corresponding improvement in auditory comprehension.
