Dorsolateral+Frontal+Lobe+Syndrome

This syndrome is characterized by difficulty planning novel cognitive activity and carrying out sequential tasks. Although cognitive abilities such as language, memory, and visuospatial skills are themselves intact, individuals with dorsolateral lesions lack executive control and therefore cannot properly use these skills. "Knowledge is divorced from action"

In this syndrome executive function deficits are paramount, implying the individual is deficient in: -Planning -Monitoring -Flexibility of behavior -Difficulty solving problems involving foresight, goal selection,resistance to interference, use of feedback and sustained effort -Appears inattentive -Unmotivated -Perseveration -Stimulus-bound behavior (e.g. incorrectly draws hands on clock at the 10 and 11 when asked to show 11:10 -Echopraxia - involuntary imitation of others gestures (indicates inhibited personal monitoring -Working memory may be effected and overlap with inability for sustained attention

-motor Aphasia -diminished verbal fluency a helpful test is the Wisconson Card Sorting Task
 * Left dorsolateral lesions**

-Transcortical motor aprosody
 * Right dorsolateral lesions**

Broadman's areas 8,9,10,46,47 can be found bilaterally in those who have prominent executive function deficits
