The late sequel of cranio-cerebral trauma are common causes of decreased mental capability and pathology localized in frontal lobes which can cause the dysexecutive syndrome (the individual has a goal but has difficulty in generating or activating the appropriate goal directed behavior). We analysed 58 patients, random-chosen, treated in the Neurotraumatology Department in Kraków after craniocerebral injury. Among them, 6 patients were found who scored more than average in DEX questionnaire. It was shown that diagnosis of DEX enables use of neuropsychological rehabilitation, which can improve final outcome.
