Language

'Aphasia is an acquired neurogenic language disorder resulting from an injury to the brain, typically the left hemisphere, that affects the functioning of core elements of the language network. Aphasia involves varying degrees of impairment in four primary areas:

• spoken language expression
• written expression
• spoken language comprehension
• reading comprehension

Aphasia may also result from neurodegenerative disease.'
