Cognitive-communication disorders are problems with communication secondary to a cognitive deficit rather than a primary language or speech deficit. A cognitive-communication disorder is a result from an impairment in one or more cognitive processes:
Insight and judgment
These processes are controlled by many cortical and subcortical structures within the brain. If someone is in a car accident and has a traumatic brain injury the frontal lobe might be damaged or if someone has a stroke in the middle of the night in the right hemisphere, it can cause processes to stop working. A person with a cognitive-communication disorder may have difficulty paying attention to a conversation, staying on topic, remembering information, responding correctly, understanding jokes or metaphors, or following directions. Cognitive-communication disorders vary in severity. Someone with a mild deficit may simply have difficulty concentrating in a loud environment, whereas a person with a more severe impairment may be unable to communicate at all.
What causes this?
