Dysexecutive syndrome (DES) is defined as an
impairment of executive functions constituting of two domains: behavioral
dysexecutive syndrome (BDES) and cognitive dysexcutive syndrome (CDES) which
are not accompanied always. A growing body of studies demonstrated that BDES is
a common post-stroke neuropsychiatric comorbidity. The prevalence of BDES instroke survivors varies ranging from 3% to 25% possibly attributed to the lackof standardized diagnosis methods and variances in study sample and study mode.

Post-stroke BDES comprises varieties of
clinical presentations, the most prevalent of which are anosognosia and hypo
activity with apathy-abulia. The clinical course of BDES in stroke population
has not yet fully elucidated. Some studies showed that there was only a minor
decrease of prevalence of BDES several months after stroke, suggesting the
possible chronicity of BDES. Possible clinical correlates of behavioral
symptoms in stroke are global cognitive impairment, executive dysfunction,
premorbid personality and psychopathology and stroke severity.
