The brain is responsible for all of our cognitive or intellectual functioning. Cognition refers to the way a person thinks, learns, and remembers. A person who has had a stroke may have problems in any of these areas. The stroke may also affect the patient's ability to judge and reason and understand, as well as to concentrate and plan.
Problems with cognition may not be seen right away. They may become more noticeable when the patient begins to do things on their own. A formal evaluation by a neuropsychologist may be useful in determining the extent of the problem. Therapists can help with the re-learning process. Cognitive retraining is important so that the patient can function as safely as possible once they return home.
