Reading is an aspect of language function, but also requires visual processing skills. Unsurprisingly, given the role of the very front parts of the brain (the 'prefrontal cortex Cortex
The outer surface of the brain.') as monitors of everything that the brain does, damage there can also affect reading ability. This is often seen in people who do not read, even though they are able - i.e., they have lost the initiative to read.
