Many patients recovering from a stroke experience some degree of emotional difficulties and/or cognitive changes. A therapy called cognitive remediation — also known as cognitive rehab or cognitive rehabilitation — can help.
Cognitive dysfunction is a frequent complication of a stroke. A stroke may cause physical changes to brain tissue and can lead to diffuse cognitive deficits, including problems with attention, memory, executive functioning, and information processing.
Executive functioning problems include difficulty with executing “everyday actions,” such as carrying out a sequence of actions, planning a task, beginning a task, knowing when one has completed a task, or even becoming “lost” while in the middle of a task. Executive functioning problems are highly related to problems carrying out everyday activities.
A stroke also affects mood and emotions, and this is not simply a reaction to a life-threatening event. The area of the brain in which a stroke occurs determines what functions are affected, which could be not only speech, motor control, or cognition, but even emotions. For example, damage to the left temporal lobe is associated with low mood, but damage on the right side can produce manic reactions. Damage in the frontal lobe will often modify emotional processing and behavior.
Cognitive remediation is a valuable therapy to help a patient overcome all of these difficulties. Cognitive remediation treatment can teach long-lasting skills that help restore everyday functioning. Research has demonstrated that cognitive remediation interventions that incorporated elements of memory, processing speed, and attention led to significant improvements in a number of cognitive areas.
The good news is that everyone, even after suffering a stroke, has intact cognitive abilities and strengths. Cognitive remediation therapy teaches a patient to use those existing abilities to compensate for deficits in other areas. Cognitive remediation treatment incorporates all domains of functioning: emotional, behavioral, and cognitive.
Cognitive rehabilitation is based on the principle of neuroplasticity, meaning that the human brain is not a static organ but can be physically changed. These changes can occur within neural pathways and synapses after exposure to enriched environments. Cognitive remediation provides such an enriched environment.
What is cognitive remediation/cognitive rehabilitation?
Behavioral, emotional, and cognitive changes after a stroke can be stressful, but with quality rehabilitation a patient can achieve excellent results and a good quality of life.
Weill Cornell is pleased to offer several services to assist patients after a stroke, including a comprehensive Cognitive Remediation Program that focuses on improving working memory, attention, and focus. The five-week program includes personal consultation, telephone sessions, and online components designed to improve performance in a wide range of cognitive tasks.
