executive dysfunction
Impairment in higher-level cognitive processes including planning, decision-making, problem-solving, and behavioral regulation, commonly seen after frontal lobe injury.
Full Definition
Executive dysfunction refers to deficits in the cognitive processes responsible for goal-directed behavior, including planning, organization, decision-making, problem-solving, working memory, cognitive flexibility, and behavioral regulation. These impairments are commonly observed following damage to the frontal lobes, particularly the prefrontal cortex, and can result from traumatic brain injury, stroke, neurodegenerative diseases, or psychiatric conditions. In neurorehabilitation, executive dysfunction can significantly impact functional independence, safety awareness, and the ability to participate effectively in therapy. Symptoms may include difficulty initiating tasks, poor time management, inflexibility in problem-solving, impaired judgment, and challenges with multi-tasking. Assessment typically involves standardized neuropsychological tests, and intervention strategies focus on strategy training, environmental modifications, and compensatory techniques.
