Damage to the dorsolateral prefrontal cortex disrupts executive control, producing a dysexecutive syndrome characterized by difficulties with planning, organizing, set-shifting, and monitoring performance. When internal goals and strategies fail, behavior tends to be driven by external cues, leading to stimulus-bound behavior. Frontal release signs are not prominent with this pattern, since those primitive reflexes more often reflect dysfunction in other frontal areas. Medial frontal and orbitofrontal injuries tend to yield disinhibition or motivation abnormalities rather than the classic planning and problem-solving deficits of dysexecutive syndrome. Taken together, the profile described aligns best with damage to the dorsolateral prefrontal cortex.
