executive dysfunction
Impairment in higher-order cognitive processes including planning, decision-making, and cognitive flexibility.
Full Definition
Executive dysfunction refers to impairments in the higher-order cognitive processes that govern goal-directed behavior, including planning, working memory, cognitive flexibility, abstract reasoning, and inhibitory control. These functions are primarily mediated by the prefrontal cortex and its connections to other brain regions. Executive dysfunction commonly occurs in various neurological and psychiatric conditions including dementia, traumatic brain injury, ADHD, and schizophrenia. Manifestations may include difficulty organizing tasks, poor judgment, impulsivity, perseveration, and problems with multitasking or adapting to changing situations. Clinical assessment often involves neuropsychological tests such as the Wisconsin Card Sorting Test, Trail Making Test, or Stroop Test to evaluate different aspects of executive function.
