A cognitive communication disorder is a broad term that's used to describe a wide range of specific communication problems that can result from damage to regions of the brain that control your ability to think (cognition). This damage can impair your ability to transform thoughts into meaningful speech, writing, or gestures.

They can range from simple sound repetitions, such as stuttering, to occasional misarticulation of words and complete inability to use speech and language for communications (aphasia).
